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.

Illegal solar push ravages Hambantota elephant habitat: Environmentalist warns of deepening crisis

Published

on

Land earmarked for the project

A large-scale move to establish solar power plants in Hambantota has triggered a major environmental and social crisis, with more than 1,000 acres of forest—identified as critical elephant habitat—cleared in violation of the law, environmental activist Sajeewa Chamikara said.

Chamikara, speaking on behalf of the Movement for Land and Agricultural Reform, said that 17 companies have already begun clearing forest land along the boundaries of the Hambantota Elephant Management Reserve. The affected areas include Sanakku Gala, Orukemgala and Kapapu Wewa, which are known to be key elephant habitats and long-used movement corridors.

He said that what is taking place cannot be described as development, but rather as a large-scale destruction of natural ecosystems carried out under the cover of renewable energy expansion.

According to Chamikara, the clearing of forests has been carried out using heavy machinery, while large sections have also been deliberately set on fire to prepare the land for solar installations. He said that electric fences have been erected across wide stretches of land, effectively blocking elephant movement and fragmenting their natural habitat.

“These forests are not empty lands. They are part of a living system that supports wildlife and nearby communities. Once destroyed, they cannot be easily restored,” he said.

The projects in question include a 50 megawatt solar development undertaken by five companies and a larger 150 megawatt project implemented by 12 companies. The larger project is reported to be valued at around 150 million US dollars.

Chamikara stressed that these projects are being carried out in a coordinated manner and involve extensive land clearing on a scale that raises serious environmental concerns.

He further alleged that certain companies had paid about Rs. 14 million to secure support and move ahead with the projects. He said this points to a troubling failure of oversight by state institutions that are expected to protect forests and wildlife habitats.

“This is not only an environmental issue. It is also a serious governance issue. The institutions responsible for protecting these lands have failed in their duty,” he said.

Chamikara pointed out that under the National Environmental Act, any project of this scale must receive prior approval through a proper Environmental Impact Assessment process.

He said that clearing forest land before obtaining such approval is a direct violation of the law.

He added that legal requirements relating to archaeological assessments had also been ignored. Under existing regulations, large-scale land clearing requires prior evaluation to ensure that sites of historical or cultural value are not damaged.

“The law is very clear. You cannot go ahead with projects of this nature without proper approval. What we are seeing is a complete disregard for legal procedure,” Chamikara said.

The environmental impact of these activities is already becoming visible. With their natural habitats destroyed, elephants are increasingly moving into nearby villages in search of food and shelter. This has led to a sharp rise in human-elephant conflict in several areas.

Areas such as Mayurapura, Gonnooruwa, Meegahajandura and Thanamalvila have reported increasing encounters between humans and elephants. According to Chamikara, more than 5,000 farming families in these areas are now facing growing threats to their safety and livelihoods.

 

He warned that farmers are being forced to abandon their lands due to repeated elephant intrusions, while incidents involving damage to crops and property are rising. There have also been increasing reports of injuries and deaths among both humans and elephants.

“This is turning into a serious social and economic problem. When farmers cannot cultivate their lands, it affects food production, income and rural stability,” he said.

Chamikara also raised concerns about the broader environmental consequences of clearing forests for solar power projects. While renewable energy is promoted as a solution to reduce carbon emissions, he said that destroying forests undermines that goal.

“Forests play a key role in absorbing carbon dioxide. When you clear and burn them, you are increasing emissions, not reducing them. That defeats the purpose of promoting solar energy,” he explained.

He added that large-scale deforestation in dry zone areas such as Hambantota could also affect local weather patterns and reduce rainfall, which would have further negative impacts on agriculture and water resources.

Chamikara called for a shift in policy, urging authorities to focus on more sustainable approaches to solar power development. He said that rooftop solar systems on homes, public buildings and commercial establishments should be given priority, as they do not require clearing large areas of land.

He also recommended that solar projects be located on degraded or abandoned lands, such as areas affected by past mining or other low-value lands, rather than forests or productive agricultural areas.

“Renewable energy development must be done in a way that does not destroy the environment. There are better options available if there is proper planning,” he said.

Chamikara urged the Central Environmental Authority and the Department of Wildlife Conservation to take immediate action to stop ongoing land clearing and investigate the projects. He stressed that all activities carried out without proper approval should be halted until legal requirements are met.

He warned that failure to act now would lead to long-term environmental damage that could not be reversed.

“If this continues, we will lose not only forests and wildlife, but also the balance between people and nature that supports rural life. The consequences will be felt for generations,” he said.

The situation in Hambantota is fast emerging as a critical test of whether development goals can be balanced with environmental protection. As pressure grows, the response of authorities in the coming weeks is likely to determine whether the damage can still be contained or whether it will continue to spread unchecked.

Why Mahatma Gandhi’s teachings need to be at the heart of conflict resolution

Published

on

Mahatma Gandhi

All credit to the Tamil Nadu government for taking concrete measures to perpetuate the memory of the renowned Mahatma Gandhi of India, who on account of his moral teachings stands on par with the likes of Socrates, Plato, Aristotle, Confucius and Jalaluddin Rumi, to name a few such all-time greats. The time is indeed ripe to draw the world’s attention to the Mahatma’s humanistic legacy which has resonated in the hearts of peace-oriented sections the world over down the decades.

Under its mega developmental blueprint titled ‘ Tamil Nadu 2030’, the Tamil Nadu government, among other things, intends transforming villages into centres of economic growth in conformity with the Mahatma’s vision of making the village the fundamental unit of material and spiritual advancement. Thus will come into being the ‘Uttamar Gandhi Model Villages Project’, which will be initially covering 10 village Panchayats. (Please see page 3 of The Island of March 11, 2026).

The timeliness of remembering and appreciating anew the teachings of Mahatma Gandhi resides in the utter lawlessness that has been allowed to overtake the world over the last few decades by none other than those global powers which took it upon themselves to usher in a world political and economic order based on the UN Charter and the Universal Declaration of Human Rights. Mainly in ‘the dock’ in this regard are the permanent members of the UN Security Council.

As is plain to see, the international law and order situation has veered out of control. Principal priorities for the international community or what’s left of it is to prevent the current mainly regional war in the Middle East from degenerating dangerously into another world war, coupled with the task of eliminating the possibility of another nuclear holocaust.

The most scorching of ironies is that the world’s ‘number one power’, the US, has virtually lost its way in the ‘Global Disorder’ it has been party to letting lose. For instance, instead of making good its boast of militarily neutralizing Iran and paving the way for the constant flow of fuel and gas from the Strait of Hormus by itself and Israel, it is now appealing to the rest of the West to come to its assistance. Not surprisingly, US allies are indicating their unwillingness to help pull the US’ ‘chestnuts out of the fire’.

Oil and gas are the veritable life blood of countries and going ahead it should not come as a surprise if impatience gets the better of the major powers and the nuclear option is resorted to by some of them under the dangerous illusion that it would be a quick-fix to their growing economic ills and frustrations.

All the above and more are within the realms of the possible and the need is pressing for humanistic voices to take centre stage in the present runaway crisis. As pointed out in this column last week, Realpolitik has overtaken the world and unless the latter is convinced of the self-destructive nature of the major powers’ policy of ‘meeting fire with fire’ to resolve their disputes, annihilation could be the lot of a good part of the world.

For far too long the voice of humanity has been muted and silenced in the affairs of the world by the incendiary threats and counter-threats of the big powers and their allies. No quarter has been bold enough in these blood pressure-hiking slanging matches to speak of the need for brotherly love and compassion among nations and countries. But it’s the language of love and understanding that is the most pressing need currently and the Mahatma in his time did just that against mighty odds.

At present the US and Iran are trading threats and accusations over military-related developments in the Gulf and it’s anybody’s guess as to what turn these events will take. However, calming voices of humanity and moderation would help in deescalating tensions and such voices need to go to the assistance of the UN chief and his team.

The Mahatma used the technique of ‘Satyagraha’ or the policy of non-violent resistance to oppose and dis-empower to a degree the British empire in his time and the current major powers would do well to take a leaf from Gandhi. The latter also integrated into the strategy of non-violent resistance the policy of ‘Ahimsa’ or love and understanding which helped greatly in uniting rather than alienating adversaries. The language of love, it has been proved, speaks to the hearts and minds of people and has a profoundly healing impact.

Mahatma Gandhi defined the ideal of ‘Ahimsa’ thus: ‘In its positive form, “Ahimsa” means the largest love, the greatest charity. If I am a follower of “Ahimsa”, I must love my enemy or a stranger to me as I would my wrong-doing father or son. This active “Ahimsa” necessarily includes truth and fearlessness.’ (See; ‘Modern Indian Political Thought; Text and Context’ by Bidyut Chakrabarty and Rajendra Kumar Pandey, Sage Publications India, Pvt. Ltd., www.sagepub.in).

In the latter publication, the authors also defined the essence of ‘satyagraha’ as ‘protest without rancour’ and this is seen as ‘holding the key to his entire campaign’ of non-violent resistance. From these perspectives, the teaching, ‘hatred begets hatred’ acquires more salience and meaning.

Accordingly, the voice of reason and love needs to come centre stage and take charge of current international political discourse. The UN and allied organizations which advocate conflict resolution by peaceful means need to get together and ensure that their voices are clearly heard and understood. The global South could help in this process by seeing to the vibrant rejuvenation of organizations such as the Non-aligned Movement.

An immediate task for the peace-oriented and well meaning is to make the above projects happen fast. In the process they should underscore afresh the profound importance of the teachings of Mahatma Gandhi, who is acclaimed the world over as a uniting and healing political personality and prophet of peace.

If the Mahatma is universally acclaimed, the reason is plain to see. Put simply, he spoke to the hearts and minds of people everywhere, regardless of man-made barriers. The language of peace and brotherhood, that is, is understood by everyone. The world needs more prophets of peace and reconciliation of the likes of the Mahatma to drown out the voices of discord and war-mongering and ensure that the language of humanity prevails.
