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.

Mannar’s silent skies: Migratory Flamingos fall victim to power lines amid Wind Farm dispute
By Ifham Nizam
A fresh wave of concern has gripped conservationists following the reported deaths of migratory flamingos within the Vankalai Sanctuary—a globally recognised bird habitat—raising urgent questions about the ecological cost of large-scale renewable energy projects in the region.
The incident comes at a time when a fundamental rights petition, challenging the proposed wind power project, linked to India’s Adani Group, remains under examination before the Supreme Court, with environmental groups warning that the very risks they highlighted are now materialising.
At least two flamingos—believed to be part of the iconic migratory flocks that travel thousands of kilometres to reach Sri Lanka—were found dead after entanglement with high-tension transmission lines running across the sanctuary. Another bird was reportedly struggling for survival.
Professor Sampath Seneviratne, a leading ornithologist, expressed deep concern over the development, noting that such incidents are not isolated but indicative of a broader and predictable threat.
“These migratory birds depend on specific flyways that have remained unchanged for centuries. When high-risk infrastructure, like poorly planned power lines, intersect these routes, collisions become inevitable,” he said. “What we are witnessing now could be just the beginning if proper mitigation measures are not urgently implemented.”
Environmentalists argue that the Mannar region—particularly the Vankalai wetland complex—is one of the most critical stopover sites in South Asia for migratory waterbirds, including flamingos, pelicans, and various species of waders. The sanctuary’s ecological value has also supported a niche with growing eco-tourism sector, drawing birdwatchers from around the world.
Executive Director of the Centre for Environmental Justice, Dilena Pathragoda, said the incident underscores the urgency of judicial intervention and stricter environmental oversight.
“This tragedy is a direct consequence of ignoring scientifically established environmental safeguards. We have already raised these concerns before court, particularly regarding the location of transmission infrastructure within sensitive bird habitats,” Pathragoda said.
“Renewable energy cannot be pursued in isolation from ecological responsibility. If due process and proper environmental impact assessments are bypassed or diluted, then such losses are inevitable.”
Conservation groups have long cautioned that the installation of wind turbines and associated grid infrastructure—especially overhead transmission lines—within or near sensitive habitats could transform these landscapes into lethal zones for avifauna.
An environmental activist involved in the ongoing legal challenge said the latest deaths validate earlier warnings.
“This is exactly what we feared. Development is necessary, but not at the cost of biodiversity. When projects of this scale proceed without adequate ecological assessments and safeguards, the consequences are irreversible,” the activist stressed.
The debate has once again brought into focus the delicate balance between renewable energy expansion and biodiversity conservation. While wind energy is widely promoted as a clean alternative to fossil fuels, experts caution that “green” does not automatically mean “harmless.”
Professor Seneviratne emphasised that solutions do exist, including rerouting transmission lines, installing bird diverters, and conducting comprehensive migratory pathway studies prior to project approval.
“Globally, there are well-established mitigation strategies. The issue here is not the absence of knowledge, but the failure to apply it effectively,” he noted.
The timing of the incident is particularly worrying. Migratory flamingos typically remain in Sri Lanka until late April or May before embarking on their return journeys. Conservationists warn that if hazards remain unaddressed, larger flocks could face similar risks in the coming weeks.
Beyond ecological implications, experts also highlight potential economic fallout. Wildlife tourism—especially birdwatching—contributes significantly to local livelihoods in Mannar.
Repeated reports of bird deaths could deter eco-conscious travellers and damage the region’s reputation as a safe haven for migratory species.
Environmentalists are now calling for immediate intervention by authorities, including a temporary halt to high-risk operations in sensitive zones, pending a thorough environmental review.
They stress that protecting animal movement corridors—whether elephant migration routes or avian flyways—is a fundamental pillar of modern conservation.
As the controversy unfolds, one question looms large: can Sri Lanka pursue sustainable energy without sacrificing the very natural heritage that defines it?
Pathragoda added that for now, the sight of fallen flamingos in Mannar stands as a stark reminder that development, if not carefully planned, can carry a heavy and irreversible cost.

‘Weaponizing’ religion in the pursuit of power
A picture of US President Donald Trump apparently being prayed for by supporters, appearing in sections of the international media, said it all loud and clear. That is, religion is being flagrantly leveraged or prostituted by politicians single-mindedly bent on furthering their power aspirations.
Although in the case of the US President the trend took on may be an exceptionally graphic or dramatic form, the ‘weaponizing’ of religion is nothing particularly new, nor is it confined to only religiously conservative sections of the West. For example, in South Asia it is an integral part of politics. The ‘South Asian Eight’ are notorious for it and it could be unreservedly stated that in Sri Lanka, the latter’s ethnic conflict would be more amenable to resolution if religion was not made a potent weapon by ambitious politicians of particularly the country’s South.
The more enlightened sections of Christian believers in the US may not have been able to contain their consternation at the sight of the US President apparently being ‘blessed’ by pastors claiming adherence to Christianity. Any human is entitled to be blessed but not if he is leading his country to war without exhausting all the options at his disposal to end the relevant conflict by peaceful means.
More compounded would be his problem if his directives lead to the death of civilians in the hundreds. In the latter case he is stringently accountable for the spilling of civilian blood, that is, the committing of war crimes.
However, the US along with Israel did just that in the recent bombings of Iran, for instance. The majority of the lives lost were those of civilians. If the US President is endowed with a Christian conscience he would have paused to consider that he is guilty of ordering the taking of the life of another human which is forbidden in the teachings of Jesus Christ.
Moreover, the ‘pastors’ praying over the US President should have thought on the above lines as well. May be they were in an effort to curry the President’s favour which is as blame-worthy as legitimizing in some form the taking of civilian lives. Apparently, the realisation is not dawning on all Christian conservatives of the US that some of these ‘pastors’ could very well be the proverbial false prophets and the latter are almost everywhere, even in far distant Sri Lanka.
However, the political reality ‘on the ground’ is that the Christian Right is a stable support base of the Republican Right in the US. Considering this it should not come as a surprise to the seasoned political watcher if the Christian Right, read Christian fundamentalists, are hand-in-glove, so to speak, with President Trump. But it is a scathing indictment on these rightist sections that they are all for perpetrating war and destruction and not for the fostering of peace and reconciliation. Ideally, they should have impressed on their President the dire need to make peace.
That said, political commentators should consider it incumbent on themselves to point out that religion is being ‘weaponized’ in Iran as well. Theocratic rule in Iran has been essentially all about perpetuating the power of the clerical class. The reasons that led to the Islamic Revolution in Iran are complex and the indiscreet Westernization of Iran under the Shah dynasty is one of these but one would have expected Iran to develop from then on into a multi-party, pluralistic democratic state where people would be enjoying their fundamental rights, as enshrined in the Universal Declaration of Human Rights, for example.
Moreover, Iran should have taken it upon itself to be a champion of world peace, in keeping with its Islamic credentials. But some past regimes in Iran had vowed to virtually bomb Israel out of existence and such regional policy trajectories could only bring perpetual conflict and war. Considering the current state of the Middle East it could be said that the unfettered playing out of these animosities is leading the region and the world to ‘reap the whirlwind’, having recklessly ‘sowed the wind’.
However, religious fundamentalism-inspired conflict and war has spread well beyond the Middle East into almost every region since 1979, the year of the Islamic Revolution in Iran. So much so, knowledgeable opinion now points out that religious identity has come to replace nationalism as a principal shaper of international politics or “geopolitics”, as quite a few sections misleadingly and incorrectly term it.
Elaborating on the decisive influence of religious identity, the well known and far traveled Western journalist Patrick Cockburn says in his authoritative and comprehensive book titled, ‘The Age of Jihad – Islamic State and the Great War for the Middle East’ at page 428 in connection with the war in Chechnya ; ‘If nationalism was not entirely dead, it no longer provided the ideological glue necessary to hold together and motivate people who were fighting a war. Unlike the Islamic faith, it was no longer a belief or a badge of identity for which people would fight very hard.’ (The book in reference was published by VERSO, London and New York).
In his wide coverage of Jihadist Wars the world over Cockburn goes on to state that today a call from a cleric could motivate his followers to lay down no less than their lives for a cause championed by the former. The 9/11 catastrophe alone should convince the observer that this is indeed true.
However, as often pointed out in this column, there is no alternative but to foster peace and reconciliation if a world free of bloodshed and strife is what is being sought. Fortunately we are not short of illustrious persons from the East and West who have shone a light on how best to get to a degree of peace. Besides Mahatma Gandhi of India, who was the subject of this column last week, we have former President of Iran Mohammad Khatami, who made a case for a ‘Dialogue of Civilizations’ rather than a ‘Clash of Civilizations’.
The time is more than ripe to take a leaf from these illustrious personalities, for, the current state of war in the Middle East has raised the possibility of a war that could transcend regional boundaries. The antagonists are obliged to exhaust all the peaceful options with the assistance of the UN system. Besides, war cannot ever have the blessings of the sane.

Venerable Rahula Thera’s 35-year green mission and national Namal Uyana
It was 35 years ago, on March 28, 1991, that Venerable Rahula Thera, then a young monk, embarked on a journey to the Na forest in Ulpathagama, Palagama, in the Anuradhapura District. Today, three and a half decades later, this mission stands as living proof of the enduring bond between Buddhist philosophy and the natural world.
Marking the 35th year of this green mission, Rahula Thera’s relentless dedication has transformed the National Namal Uyana into an environmental landmark admired not only across Sri Lanka but around the globe, as well.
When studying the life of Venerable Rahula Thera, one cannot ignore the profound connection between Buddhism and the environment. Buddhism is a philosophy deeply attuned to nature. The historical use of the sacred “Na Ruka” by all four Buddhas: Mangala Buddha, Sumana Buddha, Revata Buddha, and Sobhita Buddha — for enlightenment —demonstrates that from time immemorial, Buddhism has maintained a sacred bond with the Na tree. From the birth of Siddhartha to his enlightenment, the propagation of the Dharma, and even the great Parinirvana, all of these milestones unfolded in verdant, living landscapes.
Venerable Rahula Thera did not embark on the Namal Uyana mission seeking government support or personal gain. His commitment sprang from a deep devotion to the Buddha’s teachings on grove cultivation. A grove cultivator is one who spreads compassion for nature. As the Vanaropa Sutta teaches:
Venerable Rahula Thera reclaimed Namal Uyana which was then under the control of timber smugglers and treasure hunters. The term “Wanawasi” does not merely mean living in a forest; it signifies finding rest and enlightenment through nature, free from the destructive roots of greed, sin, and delusion.
Another defining aspect of Venerable Rahula Thera’s 35-year mission is the purification of the human mind. He has consistently taught the thousands who visit Namal Uyana that a person who loves a tree will never harm another human being. As the Dhamma proclaims:
It is important to remember that Venerable Rahula Thera devoted his life, without fear, speaking the truth and taking necessary action, tirelessly advancing the national mission he began. From 1991 to the present, he has worked with every government elected by the people, maintaining impartiality and independence from political ideology. Yet, he never hesitated to raise his voice fearlessly against any individual, of any rank or party, who committed wrongdoing.
Religious and Social Mission
The National Namal Uyana is not merely a forest; it is a magnificent heritage site, dating back to ancient times. Scattered across the landscape are boundary walls, the remains of ancient monastery complexes, and stone carvings believed to date back to the reign of King Devanampiyatissa. In earlier centuries, this sacred land had served as a meditation sanctuary for hundreds of monks. The name “National Namal Uyana,” by which this ecological and archaeological treasure is known today, was introduced by Venerable Rahula Thera in 1991. The government’s later recognition of the site as the National Namal Uyana stands as a significant achievement for both religion and national heritage.
Venerable Rahula Thera is a monk who has lived a life of renunciation. A striking example of this is his decision not to assume the position of Chief Incumbent of the National Namal Uyana Viharaya, instead entrusting the temple to the Ramanna Nikaya and its trustees. In doing so, he set a precedent for the contemporary Sangha. The Thera himself stated that he was merely the trustee of Namal Uyana, not its owner.
Legacy and Continuing Inspiration
The 35th anniversary of Venerable Wanawasi Rahula Thera’s arrival at Namal Uyana is not merely the commemoration of a period of time; it is a message of nature to future generations. Through his work, the Thera revived the ancient Hela tradition of loving trees and venerating the environment as something sacred. This religious and environmental mission remains unforgettable.
The revival experienced by Namal Uyana, after the arrival of Venerable Wanawasi Rahula Thera, is beyond simple description. Some of the major accomplishments achieved under his leadership include:
* Securing and protecting the largest Rose Quartz (Rosa Thirivana) reserve in South Asia.
* Restoring the Na forest spread across hundreds of acres, providing shelter to numerous rare plants and animal species.
* Transforming the area into a living centre for environmental education, offering practical learning experiences for thousands of schoolchildren and university students.
* Drawing the attention of world leaders and international environmentalists to Sri Lanka’s unique environmental heritage.
In recognition of his immense contribution to environmental conservation, Venerable Rahula Thera was honoured with the Presidential Environment Award and the Green Award in 2004—a significant moment in his life. Yet the Thera himself has always remained devoted to the work rather than the recognition it brings, making such appreciation even more meaningful.
