UPDATE ON COVID 19 VACCINES:

Vaccination drive commendable, but don’t lower guard

BY Dr. H. T, Wickremasinghe
Senior Consultant Paediatrician
President, Vaccine and Infectious Diseases Forum of Sri Lanka

It is commendable that the government of Sri Lanka has planned to get down 9 million doses of Covishield Vaccine from Serum Institute of India, the world’s largest vaccine manufacturing company. This vaccine is actually none other than AstraZeneca –Oxford Vaccine manufactured by The Serum Institute of India, by the name of Covishield. To date, Sri Lanka has already administered about 200,000 doses to healthcare workers. The next consignment would be given to persons over 65 years and persons with comorbid conditions such as diabetes, hypertension, heart disease and kidney disease.

With the rolling out of the vaccine globally, new observations have surfaced. The original schedule of the vaccine was to give two doses 28 days apart. This provided almost 70% immunity. However, new evidence has come out last month, suggesting that it would be better to increase the gap between two doses to 12 weeks (three months) instead of four weeks. This would offer a more robust 84% immunity. The United Kingdom is already using the 3 months interval between two doses. This will provide greater flexibility for vaccine rollout, and help the health authorities to deal with any possible supply disruptions, while consistently sustaining the maximum immunity to the public.

A study done by the independent COVID-19 Vaccine Research Group in the UK had shown that until the time of conclusion of the study at three months, a single standard dose would provide 76% protection with no declining of immunity. How long this protection would last is not known yet. But time would tell us. As with any other vaccine, an introduction of a second dose at three months would certainly boost the immunity.

The second observation made during the roll out of this vaccine is that it appears to provide some form of protection to community spread of the disease. This study revealed that there was 67% reduction in community spread of the disease. This is in fact very good news, as when we go on vaccinating more and more people, there would be less and less community spread of the disease, reducing the burden on hospital medical services.

Another issue which surfaced while rolling out of the vaccine is the safety and efficacy of the vaccine in persons over 65 years of age. Unfortunately, all phase 3 trials done by AstraZeneca have not included many persons over 65 years of age. They primarily targeted the 18-55 year age group. According to the data from AstraZeneca’s phase 3 trials, only two out of 660 persons in the trial aged over 65 were infected with COVID-19. Such a small number of participants is grossly insufficient to make a global decision. It is obvious that AstraZeneca has failed to provide reasonable data of safety and efficacy of their vaccine in the elderly population. They are already paying the penalty as countries such as Germany, France, Austria, and South Africa have declined to use the vaccine for persons over 65 years, despite the recommendation made by the European Medicines Agency (The governing body of drug evaluation in EU countries) to use the vaccine for all ages. However, the United Kingdom decided to continue vaccination for all ages, including persons of over 80. Their interim analysis during the early part of the vaccination programme shows that the vaccine is not only effective and provide the same immunity as for others but also has slightly less side effects.

Considering the seriousness of COVID 19 in the elderly and it’s very high mortality, it is my considered opinion that even if the vaccine is less effective or has more side effects, it is still worth giving it to old persons as it would save their lives.

With more and more new genetic variations of SARS CoV 2 virus emerging, a reasonable concern has transpired among scientists whether the vaccines would be able to provide immunity to the new emerging strains. Up to now globally there are more than 8000 variants. Out of those, three variants, the South African variant, the Kent (UK) variant and the Brazilian variant are few rapidly gaining global spread. The UK variant has been identified in Colombo, Avissawella, Biyagama and Vuvuniya.

Studies done in UK has shown that AstraZeneca vaccine would provide immunity to the UK variant. However, a similar study done on over 2000 participants in South Africa has unfortunately revealed that this vaccine is not effective against the new South African strain.

There are more than 150 vaccines against COVID 19 in the production pipeline. Out of those, a dozen are nearing completion and awaiting submission of their dossiers to the World Health Organization for approval. With such a vast array of vaccines, it would be easy for WHO to distribute vaccines early to provide vaccination to all needy people in the world. But it would not be easy to have the same vaccine supply without disruptions with the expanding global demand. At the same time, some vaccines would show immunity to some new emerging variants, while another vaccine would show immunity to other variants. This brings us to another new strategy. What if we combine vaccines? Combined vaccines theoretically will provide greater flexibility for vaccine rollout and help to deal with any possible intermittent supply shortages of a particular brand.

However, the official guidance given by vaccine authorities in the world state that anyone who has already taken a vaccine should get the same brand of vaccine for both doses. The US Food and Drug Administration and the UK’s Joint Committee on Vaccination and Immunization (JCVI) recommend as much. It’s only in ‘very rare circumstances’ that vaccines of different brands may be used and only if one vaccine is available at a certain time, or it is not known which one was administered for the first dose. Nevertheless, the usefulness of a combined vaccine, in case of a short supply or with combating a new emergent variant, cannot be underestimated. New research is underway to find out the efficacy and safety of such combinations. The initial report with AstraZeneca-Pfizer vaccine combination will be available by mid-2021. Similar trials will be undertaken soon, so that the health authorities of countries would have a better and competitive option of choosing vaccines for their public.

Despite all this good news, we still have a question for which we have to wait for an answer. How long the immunity will last is the question for with no answers are available yet. Many countries have already commenced their vaccination programme, even before the introduction of the free vaccine programme by WHO sponsored COVAX. In the race of COVID-19 mass vaccination, Israel is well ahead of all the countries in the world already covering 43% of the total population. The number of new cases and deaths due to COVID-19 has come down. Even in the US, the initial wave of vaccination is slowly showing results of reduction of mortality from COVID-19 related complications.

The majority of the vaccines used so far may not provide the expected picture-perfect immunity and the world may continue to have COVID 19 infections, but based on evidence, speculations have already been made to claim that vaccination could provide almost 100% protection from death. This is what we all want.

With that positive note, let me conclude while emphasizing the need to continue our general public health measures such as wearing masks, social distancing and avoiding crowded gatherings to reduce the risk of contact with an infected person.

There is no science to beat common sense.

Disaster-proofing paradise: Sri Lanka’s new path to global resilience

Published

on

iyadasa Advisor to the Ministry of Science & Technology and a Board of Directors of Sri Lanka Atomic Energy Regulatory Council A value chain management consultant to www.vivonta.lk

As climate shocks multiply worldwide from unseasonal droughts and flash floods to cyclones that now carry unpredictable fury Sri Lanka, long known for its lush biodiversity and heritage, stands at a crossroads. We can either remain locked in a reactive cycle of warnings and recovery, or boldly transform into the world’s first disaster-proof tropical nation — a secure haven for citizens and a trusted destination for global travelers.

The Presidential declaration to transition within one year from a limited, rainfall-and-cyclone-dependent warning system to a full-spectrum, science-enabled resilience model is not only historic — it’s urgent. This policy shift marks the beginning of a new era: one where nature, technology, ancient wisdom, and community preparedness work in harmony to protect every Sri Lankan village and every visiting tourist.

The Current System’s Fatal Gaps

Today, Sri Lanka’s disaster management system is dangerously underpowered for the accelerating climate era. Our primary reliance is on monsoon rainfall tracking and cyclone alerts — helpful, but inadequate in the face of multi-hazard threats such as flash floods, landslides, droughts, lightning storms, and urban inundation.

Institutions are fragmented; responsibilities crisscross between agencies, often with unclear mandates and slow decision cycles. Community-level preparedness is minimal — nearly half of households lack basic knowledge on what to do when a disaster strikes. Infrastructure in key regions is outdated, with urban drains, tank sluices, and bunds built for rainfall patterns of the 1960s, not today’s intense cloudbursts or sea-level rise.

Critically, Sri Lanka is not yet integrated with global planetary systems — solar winds, El Niño cycles, Indian Ocean Dipole shifts — despite clear evidence that these invisible climate forces shape our rainfall, storm intensity, and drought rhythms. Worse, we have lost touch with our ancestral systems of environmental management — from tank cascades to forest sanctuaries — that sustained this island for over two millennia.

This system, in short, is outdated, siloed, and reactive. And it must change.

A New Vision for Disaster-Proof Sri Lanka

Under the new policy shift, Sri Lanka will adopt a complete resilience architecture that transforms climate disaster prevention into a national development strategy. This system rests on five interlinked pillars:

Science and Predictive Intelligence

We will move beyond surface-level forecasting. A new national climate intelligence platform will integrate:

AI-driven pattern recognition of rainfall and flood events

Global data from solar activity, ocean oscillations (ENSO, MJO, IOD)

High-resolution digital twins of floodplains and cities

Real-time satellite feeds on cyclone trajectory and ocean heat

The adverse impacts of global warming—such as sea-level rise, the proliferation of pests and diseases affecting human health and food production, and the change of functionality of chlorophyll—must be systematically captured, rigorously analysed, and addressed through proactive, advance decision-making.

This fusion of local and global data will allow days to weeks of anticipatory action, rather than hours of late alerts.

Advanced Technology and Early Warning Infrastructure

Cell-broadcast alerts in all three national languages, expanded weather radar, flood-sensing drones, and tsunami-resilient siren networks will be deployed. Community-level sensors in key river basins and tanks will monitor and report in real-time. Infrastructure projects will now embed climate-risk metrics — from cyclone-proof buildings to sea-level-ready roads.

Governance Overhaul

A new centralised authority — Sri Lanka Climate & Earth Systems Resilience Authority — will consolidate environmental, meteorological, Geological, hydrological, and disaster functions. It will report directly to the Cabinet with a real-time national dashboard. District Disaster Units will be upgraded with GN-level digital coordination. Climate literacy will be declared a national priority.

People Power and Community Preparedness

We will train 25,000 village-level disaster wardens and first responders. Schools will run annual drills for floods, cyclones, tsunamis and landslides. Every community will map its local hazard zones and co-create its own resilience plan. A national climate citizenship programme will reward youth and civil organisations contributing to early warning systems, reforestation (riverbank, slopy land and catchment areas) , or tech solutions.

Reviving Ancient Ecological Wisdom

Sri Lanka’s ancestors engineered tank cascades that regulated floods, stored water, and cooled microclimates. Forest belts protected valleys; sacred groves were biodiversity reservoirs. This policy revives those systems:

Restoring 10,000 hectares of tank ecosystems

Conserving coastal mangroves and reintroducing stone spillways

Integrating traditional seasonal calendars with AI forecasts

Recognising Vedda knowledge of climate shifts as part of national risk strategy

Our past and future must align, or both will be lost.

A Global Destination for Resilient Tourism

Climate-conscious travelers increasingly seek safe, secure, and sustainable destinations. Under this policy, Sri Lanka will position itself as the world’s first “climate-safe sanctuary island” — a place where:

Resorts are cyclone- and tsunami-resilient

Tourists receive live hazard updates via mobile apps

World Heritage Sites are protected by environmental buffers

Visitors can witness tank restoration, ancient climate engineering, and modern AI in action

Sri Lanka will invite scientists, startups, and resilience investors to join our innovation ecosystem — building eco-tourism that’s disaster-proof by design.

Resilience as a National Identity

This shift is not just about floods or cyclones. It is about redefining our identity. To be Sri Lankan must mean to live in harmony with nature and to be ready for its changes. Our ancestors did it. The science now supports it. The time has come.

Let us turn Sri Lanka into the world’s first climate-resilient heritage island — where ancient wisdom meets cutting-edge science, and every citizen stands protected under one shield: a disaster-proof nation.

The minstrel monk and Rafiki the old mandrill in The Lion King – I

Published

on

Why is national identity so important for a people? AI provides us with an answer worth understanding critically (Caveat: Even AI wisdom should be subjected to the Buddha’s advice to the young Kalamas):

‘A strong sense of identity is crucial for a people as it fosters belonging, builds self-worth, guides behaviour, and provides resilience, allowing individuals to feel connected, make meaningful choices aligned with their values, and maintain mental well-being even amidst societal changes or challenges, acting as a foundation for individual and collective strength. It defines “who we are” culturally and personally, driving shared narratives, pride, political action, and healthier relationships by grounding people in common values, traditions, and a sense of purpose.’

Ethnic Sinhalese who form about 75% of the Sri Lankan population have such a unique identity secured by the binding medium of their Buddhist faith. It is significant that 93% of them still remain Buddhist (according to 2024 statistics/wikipedia), professing Theravada Buddhism, after four and a half centuries of coercive Christianising European occupation that ended in 1948. The Sinhalese are a unique ancient island people with a 2500 year long recorded history, their own language and country, and their deeply evolved Buddhist cultural identity.

Buddhism can be defined, rather paradoxically, as a non-religious religion, an eminently practical ethical-philosophy based on mind cultivation, wisdom and universal compassion. It is  an ethico-spiritual value system that prioritises human reason and unaided (i.e., unassisted by any divine or supernatural intervention) escape from suffering through self-realisation. Sri Lanka’s benignly dominant Buddhist socio-cultural background naturally allows unrestricted freedom of religion, belief or non-belief for all its citizens, and makes the country a safe spiritual haven for them. The island’s Buddha Sasana (Dispensation of the Buddha) is the inalienable civilisational treasure that our ancestors of two and a half millennia have bequeathed to us. It is this enduring basis of our identity as a nation which bestows on us the personal and societal benefits of inestimable value mentioned in the AI summary given at the beginning of  this essay.

It was this inherent national identity that the Sri Lankan contestant at the 72nd Miss World 2025 pageant held in Hyderabad, India, in May last year, Anudi Gunasekera, proudly showcased before the world, during her initial self-introduction. She started off with a verse from the Dhammapada (a Pali Buddhist text), which she explained as meaning “Refrain from all evil and cultivate good”. She declared, “And I believe that’s my purpose in life”. Anudi also mentioned that Sri Lanka had gone through a lot “from conflicts to natural disasters, pandemics, economic crises….”, adding, “and yet, my people remain hopeful, strong, and resilient….”.

 “Ayubowan! I am Anudi Gunasekera from Sri Lanka. It is with immense pride that I represent my Motherland, a nation of resilience, timeless beauty, and a proud history, Sri Lanka.

“I come from Anuradhapura, Sri Lanka’s first capital, and UNESCO World Heritage site, with its history and its legacy of sacred monuments and stupas…….”.

The “inspiring words” that Anudi quoted are from the Dhammapada (Verse 183), which runs, in English translation: “To avoid all evil/To cultivate good/and to cleanse one’s mind -/this is the teaching of the Buddhas”. That verse is so significant because it defines the basic ‘teaching of the Buddhas’ (i.e., Buddha Sasana; this is how Walpole Rahula Thera defines Buddha Sasana in his celebrated introduction to Buddhism ‘What the Buddha Taught’ first published in1959).

Twenty-five year old Anudi Gunasekera is an alumna of the University of Kelaniya, where she earned a bachelor’s degree in International Studies. She is planning to do a Master’s in the same field. Her ambition is to join the foreign service in Sri Lanka. Gen Z’er Anudi is already actively engaged in social service. The Saheli Foundation is her own initiative launched to address period poverty (i.e., lack of access to proper sanitation facilities, hygiene and health education, etc.) especially  among women and post-puberty girls of low-income classes in rural and urban Sri Lanka.

Young Anudi is primarily inspired by her patriotic devotion to ‘my Motherland, a nation of resilience, timeless beauty, and a proud history, Sri Lanka’. In post-independence Sri Lanka, thousands of young men and women of her age have constantly dedicated themselves, oftentimes making the supreme sacrifice, motivated by a sense of national identity, by the thought ‘This is our beloved Motherland, these are our beloved people’.

The rescue and recovery of Sri Lanka from the evil aftermath of a decade of subversive ‘Aragalaya’ mayhem is waiting to be achieved, in every sphere of national engagement, including, for example, economics, communications, culture and politics, by the enlightened Anudi Gunasekeras and their male counterparts of the Gen Z, but not by the demented old stragglers lingering in the political arena listening to the unnerving rattle of “Time’s winged chariot hurrying near”, nor by the baila blaring monks at propaganda rallies.

Politically active monks (Buddhist bhikkhus) are only a handful out of  the Maha Sangha (the general body of Buddhist bhikkhus) in Sri  Lanka, who numbered just over 42,000  in 2024. The vast majority of monks spend their time quietly attending to their monastic duties. Buddhism upholds social and emotional virtues such as universal compassion, empathy, tolerance and forgiveness that protect a society from the evils of tribalism, religious bigotry and death-dealing religious piety.

Not all monks who express or promote political opinions should be censured. I choose to condemn only those few monks who abuse the yellow robe as a shield in their narrow partisan politics. I cannot bring myself to disapprove of the many socially active monks, who are articulating the genuine problems that the Buddha Sasana is facing today. The two bhikkhus who are the most despised monks in the commercial media these days are Galaboda-aththe Gnanasara and Ampitiye Sumanaratana Theras.  They have a problem with their mood swings. They have long been whistleblowers trying to raise awareness respectively, about spreading religious fundamentalism, especially, violent Islamic Jihadism, in the country and about the vandalising of the Buddhist archaeological heritage sites of the north and east provinces. The two middle-aged monks (Gnanasara and Sumanaratana) belong to this respectable category. Though they are relentlessly attacked in the social media or hardly given any positive coverage of the service they are doing, they do nothing more than try to persuade the rulers to take appropriate action to resolve those problems while not trespassing on the rights of people of other faiths.

These monks have to rely on lay political leaders to do the needful, without themselves taking part in sectarian politics in the manner of ordinary members of the secular society. Their generally demonised social image is due, in my opinion, to  three main reasons among others: 1) spreading misinformation and disinformation about them by those who do not like what they are saying and doing, 2) their own lack of verbal restraint, and 3) their being virtually abandoned to the wolves by the temporal and spiritual authorities.

US’ drastic aid cut to UN poses moral challenge to world

Published

on

An UN humanitarian mission in the Gaza. [File: Ashraf Amra/Anadolu Agency]

‘Adapt, shrink or die’ – thus runs the warning issued by the Trump administration to UN humanitarian agencies with brute insensitivity in the wake of its recent decision to drastically reduce to $2bn its humanitarian aid to the UN system. This is a substantial climb down from the $17bn the US usually provided to the UN for its humanitarian operations.

Considering that the US has hitherto been the UN’s biggest aid provider, it need hardly be said that the US decision would pose a daunting challenge to the UN’s humanitarian operations around the world. This would indeed mean that, among other things, people living in poverty and stifling material hardships, in particularly the Southern hemisphere, could dramatically increase. Coming on top of the US decision to bring to an end USAID operations, the poor of the world could be said to have been left to their devices as a consequence of these morally insensitive policy rethinks of the Trump administration.

Earlier, the UN had warned that it would be compelled to reduce its aid programs in the face of ‘the deepest funding cuts ever.’ In fact the UN is on record as requesting the world for $23bn for its 2026 aid operations.

If this UN appeal happens to go unheeded, the possibilities are that the UN would not be in a position to uphold the status it has hitherto held as the world’s foremost humanitarian aid provider. It would not be incorrect to state that a substantial part of the rationale for the UN’s existence could come in for questioning if its humanitarian identity is thus eroded.

Inherent in these developments is a challenge for those sections of the international community that wish to stand up and be counted as humanists and the ‘Conscience of the World.’ A responsibility is cast on them to not only keep the UN system going but to also ensure its increased efficiency as a humanitarian aid provider to particularly the poorest of the poor.

It is unfortunate that the US is increasingly opting for a position of international isolation. Such a policy position was adopted by it in the decades leading to World War Two and the consequences for the world as a result of this policy posture were most disquieting. For instance, it opened the door to the flourishing of dictatorial regimes in the West, such as that led by Adolph Hitler in Germany, which nearly paved the way for the subjugation of a good part of Europe by the Nazis.

If the US had not intervened militarily in the war on the side of the Allies, the West would have faced the distressing prospect of coming under the sway of the Nazis and as a result earned indefinite political and military repression. By entering World War Two the US helped to ward off these bleak outcomes and indeed helped the major democracies of Western Europe to hold their own and thrive against fascism and dictatorial rule.

Republican administrations in the US in particular have not proved the greatest defenders of democratic rule the world over, but by helping to keep the international power balance in favour of democracy and fundamental human rights they could keep under a tight leash fascism and linked anti-democratic forces even in contemporary times. Russia’s invasion and continued occupation of parts of Ukraine reminds us starkly that the democracy versus fascism battle is far from over.

Right now, the US needs to remain on the side of the rest of the West very firmly, lest fascism enjoys another unfettered lease of life through the absence of countervailing and substantial military and political power.

However, by reducing its financial support for the UN and backing away from sustaining its humanitarian programs the world over the US could be laying the ground work for an aggravation of poverty in the South in particular and its accompaniments, such as, political repression, runaway social discontent and anarchy.

What should not go unnoticed by the US is the fact that peace and social stability in the South and the flourishing of the same conditions in the global North are symbiotically linked, although not so apparent at first blush. For instance, if illegal migration from the South to the US is a major problem for the US today, it is because poor countries are not receiving development assistance from the UN system to the required degree. Such deprivation on the part of the South leads to aggravating social discontent in the latter and consequences such as illegal migratory movements from South to North.

Accordingly, it will be in the North’s best interests to ensure that the South is not deprived of sustained development assistance since the latter is an essential condition for social contentment and stable governance, which factors in turn would guard against the emergence of phenomena such as illegal migration.

Meanwhile, democratic sections of the rest of the world in particular need to consider it a matter of conscience to ensure the sustenance and flourishing of the UN system. To be sure, the UN system is considerably flawed but at present it could be called the most equitable and fair among international development organizations and the most far-flung one. Without it world poverty would have proved unmanageable along with the ills that come along with it.

Dehumanizing poverty is an indictment on humanity. It stands to reason that the world community should rally round the UN and ensure its survival lest the abomination which is poverty flourishes. In this undertaking the world needs to stand united. Ambiguities on this score could be self-defeating for the world community.

For example, all groupings of countries that could demonstrate economic muscle need to figure prominently in this initiative. One such grouping is BRICS. Inasmuch as the US and the West should shrug aside Realpolitik considerations in this enterprise, the same goes for organizations such as BRICS.

The arrival at the above international consensus would be greatly facilitated by stepped up dialogue among states on the continued importance of the UN system. Fresh efforts to speed-up UN reform would prove major catalysts in bringing about these positive changes as well. Also requiring to be shunned is the blind pursuit of narrow national interests.
