In this emerald isle, people take to any form of vaccination, like the legendary ducks take to water. Offer them a vaccine against anything and they will take it; at least most of them would do so. The vaccine antagonists and anti-vaxxers are extremely few and far between, so as to be almost a virtual non-entity. With a very high literacy rate, and a population that is prepared to take heed to the hilt, the axiom that dictates ‘prevention is better than cure’, it is the absolute dream of the experts in the public health scenario that there is unmitigated abiding interest on the part of our populace to get vaccinated against COVID-19. It has been said that vaccines do not save lives but vaccination most definitely does. Vaccines have to be given to people for them to produce the optimal effects. A receptive population to such a notion is indeed, a much-fancied reverie of all health service providers.
In such a background, it is most laudable that Sri Lanka is going pell-mell, even in an impetuous rush, to vaccinate her population against COVID-19, at what could best be described as at break-neck speed. Even given the spectacle of an insufficiency of adequate stocks of the coronavirus vaccines to freely vaccinate the population, the authorities are making the very best of the situation. We must, of course clearly appreciate the steps taken by the Government and the Ministry of Health in this initiative. The tri-forces, the Army in particular, have to be congratulated, in playing the lead role in organising a scheme of things to administer the vaccines in an orderly fashion. TAKE A BOW; ALL OF YOU, you are indeed giving the very best of yourselves in this endeavour.
Well, the goal is to somehow secure a high enough herd-immunity to defeat the virus; most definitely a commendable final goal. The currently prevalent mantra is to vaccinate, vaccinate, and vaccinate even more. Yet for all that there is much misinformation and an infodemic doing the rounds, especially on social media, about widespread speculations on loss of sexual prowess, impotence, subfertility and infertility, as undesirable effects of the COVID-19 vaccines. THERE IS ABSOLUTELY NO SCIENTIFIC BASIS FOR ANY OF THESE IMPLICATIONS. NONE OF THE CURRENTLY AVAILABLE COVID-19 VACCINES DO ANY OF THIS. It is just stupid covidiocy on the part of a few anti-vaxxers. It has induced a lot of young people to refuse the vaccine. This is a crime against humanity to spread such falsehoods. It is absolutely crucial to realise that the current vaccination drive is just a very important one of quite a few things we can do to try and keep the coronavirus at bay.
We have seen the fantastic results of immunisations against ‘child-killer diseases’ in paediatric healthcare. This author, as a young junior doctor, was witness to the ravages of the much-feared childhood diseases that killed or maimed scores of young children even in the second half of the last century. Those diseases such as tetanus, diphtheria, whooping cough, polio, measles, Japanese encephalitis; just to mention a few that took scores of young lives of yore, are a thing of the past now. Adequate vaccination has completely wiped them out. The last case of childhood polio in Sri Lanka was seen just around a quarter of a century ago. The young junior doctors of today and the current lot of medical students have not seen any of these dreaded diseases.
In the child healthcare scenario, vaccination has become the panacea for all ills in the above-mentioned diseases. In the same vein, it is quite reasonable to expect the coronavirus vaccines to provide a similar end-result. However, is it really so? It is a most lamentable fact that it is perhaps not quite so.
There is a well-recognised fundamental difference between all the vaccines that are used to prevent the much-feared childhood diseases of the past and the currently available vaccines against the coronavirus that is causing the current pandemic. The vaccines against all those childhood diseases COMPLETELY PREVENT children getting the disease!!!, period. Well, if the recipients are protected against getting the infection, it is the end of the story; a definitive conclusion of the matter in hand.
However, right up to just a few days ago, none of the currently available vaccines against COVID-19, were thought to be able to COMPLETELY PREVENT anyone getting the disease to any appreciable degree. How they work is by reducing the severity of the disease and by preventing the deaths. So…, the basic end-result characteristics of all the currently available COVID-19 vaccines were thought to be quite different to the standard vaccines against all other infective diseases. One could still get the disease in spite of being vaccinated against COVID-19 and would still be able to spread the illness to others.
Yet for all this, there seems to be a little bit of light at the end of the tunnel. In a most recent scientific publication in the New England Journal of Medicine, released as recently as 22nd September 2021, an interim analysis of a large study conducted in 99 centres of the USA has shown significant protection against CONTRACTING THE DISEASE as well as AGAINST MORE SEVERE DISEASE AND DEATH by the mRNA-1273 (Moderna/Spikevax) vaccine, administered as two doses 28 days apart. Vaccine efficacy in preventing Covid-19 illness was 93.2%, the effectiveness in preventing severe disease was 98.2% and the efficacy in preventing asymptomatic infection, starting 14 days after the second injection, was 63.0%. Vaccine efficacy was consistent across ethnic and racial groups, age groups, and participants with coexisting conditions. No safety concerns were identified.
Be that as it may, added to all our problems, now there is the daunting spectacle of the various types of variants and mutants, ranging from Alpha through delta, even to Epsilon and most recently to a particularly nasty strain called ‘Mu’, of the coronavirus which could cause problems even in the fully vaccinated. We still do not understand completely the potential impact of these more virulent strains in vaccinated people.
However, a case in point in relationship to these facts is the presently dominant situation in Israel. That country, one of the fastest in vaccination and most-vaccinated nations in the world, in spite of almost the entire population being vaccinated, is having some problems at the present time. By mid-March 2021, Israelis were partying as lockdowns ended and by April, masks had more or less vanished, turning the tiny country into a tantalising glimpse of a post-pandemic future. However, the crafty blight of a coronavirus seems to have come back with a vengeance. From a few dozen daily cases in early June 2021, even zero on June 9, new daily COVID infections twice hovered near 6,000 very recently, the highest daily rate in six months. Having won early access to supplies of the BioNTech/Pfizer jab in exchange for sharing nationwide data on how mass vaccination drives affect the pandemic, Israel is a closely watched indicator of a country where well-inoculated developed economies are heading.
As new infections soared, so did the long tail of hospitalisations in Israel. Even though the unvaccinated were five to six times as likely to end up seriously ill, the vaccine’s protection was waning fastest for the oldest; the most vulnerable, who got their first jabs as early as December 2020. At this rate, health officials predicted at least 5,000 people would need hospital beds by early September, half of them with serious medical needs, twice as many as Israel is equipped to handle. The current Prime Minister of Israel was honest with Israelis when he announced a new measure just a couple of weeks ago, whereby the government was trying to cushion the blow. On August 1, it had started offering people, over 60, a third shot of the Pfizer vaccine, embarking on its own public health experiment as it tumbled into an unpredictable fourth wave. So far, 775,000 people have taken their third shot and doctors say they can see antibody counts rising measurably within days of the third jab.
For Israelis, the booster shots are a reminder that they are still on the frontier of Covid-19 vaccinations. They celebrated when they were the first to get jabbed, cheering Pfizer as lockdowns ended in March 2021. Now, they are the first to experience the limits of the vaccine and the first to accept a long-whispered inevitability: the need to give regular booster shots to stay protected.
All these facts tend to bring into sharp focus, again and AGAIN, the undoubted importance of time-tested manoeuvres of avoiding crowds, maintaining a social distance of at least one to two metres, wearing suitable and effective masks; even double-masking, and repeated washing of hands, as our own personal weapons against this dastardly blight. Vaccination against COVID-19 will probably not be the panacea for all ills in combating this pandemic, although it would be a very powerful tool in the hands of the authorities in their quest towards victory over this disease. It will certainly not be the ultimate ‘SILVER BULLET’ against the disease.
If there is a lesson to be learnt from Israel today, it is this: corona, in fact, is not over; perhaps not for quite a while. This summer was just an intermission. Next may come winter., sadly perhaps, a winter of discontent. We do hope to high heaven that it may not be so for this beautiful and much-treasured Motherland of ours.

Fractious West facing a more solidified Eastern opposition
Going forward, it is hoped that a reported ceasefire agreement between the US and Iran would provide a basis for a degree of stability in the Middle East and pave the way for substantive peace talks between the powers concerned. The world is compelled to fall back on hope because there is never knowing when President Donald Trump would change his mind and plans on matters of the first importance. So erratic has he been.
Yet, confusion abounds on who has agreed to what. The US President is on record that a number of conditions put forward by him to Iran to deescalate tensions have been accepted by the latter, whereas Iran is yet to state unambiguously that this is so. For instance, the US side claims that Iran has come clear on the point that it would not work towards acquiring a nuclear weapons capability, but there is no official confirmation by Iran that this is so. The same goes for the rest of the conditions.
Accordingly, the peace process between the US and Iran, if such a thing solidly exists, could be said to be mired in uncertainty. Nevertheless, the wider publics of the world are bound to welcome the prospects of some sort of ceasing of hostilities because it would have the effect of improving their economic and material well being which is today under a cloud.
However, questions of the first magnitude would continue to bedevil international politics and provide the breeding ground for continued tensions between East and West. Iran-US hostilities helped highlight some of these divisive issues and a deescalation of these tensions would not inevitably translate into even a temporary resolution of these questions. The world community would have no choice but to take them up and work towards comprehending them better and managing them more effectively.
For example, there are thorny questions arising from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Essentially, this treaty bans the processing and use of nuclear weapons by states but some of the foremost powers are not signatories to it.
Moreover, the NPT does not provide for the destroying of nuclear arsenals by those signatory states which are already in possession of these WMDs. Consequently, there would be a glaring power imbalance between the latter nuclear-armed states and others which possess only conventional weapons.
Such a situation has grave implications for Iran’s security, for instance. The latter could argue, in view of the NPT restrictions, that the US poses a security threat to it but that it is debarred by the Treaty from developing a nuclear arms capability of its own to enable it to match the nuclear capability of the US. Moreover, its regional rival Israel is believed to possess a nuclear weapons capability.
Accordingly, a case could be made that the NPT is inherently unfair. The US would need to help resolve this vexatious matter going forward. But if it remains, US-Iran tensions would not prove easy to resolve. The same goes for Iran-Israeli tensions. Consequently, the Middle East would remain the proverbial ‘powder keg’.
Besides the above issues, the world has ample evidence that it could no longer speak in terms of a united NATO or West. Apparently, there could be no guarantee that US-NATO relations would remain untroubled in future, even if the current Iran-US standoff is peacefully resolved. US-NATO ties almost reached breaking point in the current crisis when the US President called on its NATO partners, particularly Britain, to help keep open the Hormuz Straits for easy navigation by commercial vessels, militarily, on seeing that such help was not forthcoming. Such questions are bound to remain sore points in intra-Western ties.
In other words, it would be imperative for the US’ NATO partners to help pull the US’ ‘chestnuts out of the fire’ going ahead. The question is, would NATO be willing to thus toe the US line even at the cost of its best interests.
For the West, these fractious issues are coming to the fore at a most unpropitious moment. The reality that could faze the West at present is the strong opposition shown to its efforts to bolster its power and influence by China and Russia. Right through the present crisis, the latter have stood by Iran, materially and morally. For instance, the most recent Security Council resolution spearheaded by the US which was strongly critical of Iran, was vetoed by China and Russia.
Accordingly, we have in the latter developments some marked polarities in international politics that could stand in the way of the West advancing its interests unchallenged. They point to progressively intensifying East-West tensions in international relations in the absence of consensuality.
It is only to be expected that given the substance of international politics that the West would be opposed by the East, read China and Russia, in any of the former’s efforts to advance its self interests unilaterally in ways that could be seen as illegitimate, but what is sorely needed at present is consensuality among the foremost powers if the world is to be ‘a less dangerous place to live in.’ Minus a focus on the latter, it would be a ‘no-win’ situation for all concerned.
It would be central to world stability for International Law to be upheld by all states and international actors. Military intervention by major powers in the internal affairs of other countries remains a principal cause of international mayhem. Both East and West are obliged to abide scrupulously with this principle.
From the latter viewpoint, not only did the West err in recent times, but the East did so as well. Iran, for instance, acted in gross violation of International Law when it attacked neighbouring Gulf states which are seen as US allies. Neither Iran nor the US-Israel combine have helped in advancing international law and order by thus taking the law into their own hands.
Unfortunately, the UN has been a passive spectator to these disruptive developments. It needs to play a more robust role in promoting world peace and in furthering consensual understanding among the principal powers in particular. The need is also urgent to advance UN reform and render the UN a vital instrument in furthering world peace. The East and West need to think alike and quickly on this urgent undertaking.

Science-driven health policies key to tackling emerging challenges — UNFPA
Marking World Health Day on April 7, health experts have called for a stronger commitment to science-based decision-making to address increasingly complex and evolving health challenges in Sri Lanka and beyond.
Dr. Dayanath Ranatunga, Assistant Representative of the United Nations Population Fund, stressed that health is no longer confined to hospitals or traditional medical systems, but is shaped by a broad spectrum of social, environmental, and technological factors.
“This year’s theme, ‘Together for Health. Stand with Science,’ reminds us that science is not only for laboratories or policymakers. It is a way of thinking and a tool that shapes everyday decisions,” he said.
Dr. Ranatunga noted that modern health challenges are increasingly interconnected, ranging from infectious diseases such as COVID-19 to climate-related risks, demographic shifts, and emerging forms of online violence.
He warned that maternal and newborn health continues to demand urgent attention despite progress. Globally, an estimated 260,000 women died from pregnancy and childbirth-related causes in 2023 alone—many of them preventable through timely, science-based interventions.
“In countries like Sri Lanka, where fertility rates are declining and survival rates improving, every pregnancy carries greater significance—not just for families, but for the future of communities and economies,” he said.
The UNFPA official also highlighted the growing threat of Technology Facilitated Gender-Based Violence (TFGBV), including cyber harassment and online abuse, noting that these forms of violence can have deep psychological consequences despite lacking visible physical harm.
He emphasised the need for multidisciplinary, science-informed approaches that integrate mental health, digital safety, and survivor-centered care.
Turning to demographic trends, Dr. Ranatunga pointed out that increasing life expectancy is bringing new challenges, particularly the rise of non-communicable diseases such as diabetes, cardiovascular illnesses, and cancers.
In Sri Lanka, nearly 13.9% of mothers develop diabetes during pregnancy, a trend attributed to obesity and unhealthy lifestyles, underscoring the urgent need for preventive healthcare strategies.
“Are we investing enough in prevention?” he asked, noting that early intervention and healthier lifestyles could significantly reduce long-term healthcare costs, especially in a country with a free public healthcare system.
He underscored the importance of data-driven policymaking, stating that scientific research and analytics enable governments to identify gaps, anticipate future needs, and allocate resources more effectively.
The UNFPA, he said, is already leveraging tools such as Geographic Information Systems (GIS) to improve access to maternal healthcare, including mapping travel times for pregnant women to reach health facilities.
Digital innovation is also transforming healthcare delivery, from telemedicine to real-time data systems, improving efficiency and ensuring continuity of care even during emergencies.
In Sri Lanka, partnerships between the government and development agencies are helping to modernise training institutions, including facilities in Batticaloa, equipping healthcare workers with both clinical and digital skills.
However, Dr. Ranatunga cautioned that technology alone is not a solution.
“It must be guided by evidence and grounded in equity,” he said, pointing out that women’s health remains significantly underfunded, with only about 7% of global healthcare research focusing on conditions specific to women.
He also drew attention to the growing health impacts of climate change, including extreme weather, food insecurity, and displacement, describing it as an emerging public health crisis.
“Health does not begin in hospitals. It is shaped by the environments we live in, the choices we make, and the systems we build,” he said.
Calling for renewed commitment, Dr. Ranatunga urged stakeholders to invest in prevention, embrace innovation, and ensure that science remains central to policy and practice.
“Science is not just about knowledge—it is about ensuring that everyone has the opportunity to live healthy, dignified lives, and that no one is left behind,” he added.
