Combating Covid Pandemic: When ‘Something Is Better Than Nothing’

Combating Covid Pandemic: When ‘Something Is Better Than Nothing’ 

As the new Coronavirus overwhelms the world, since its global outbreak, up until November 29, 2020, over 1,458,305 people have died from this pandemic. Understandably, the Governments in all countries are frantically searching for some robust remedial measures to prevent these unfortunate deaths, besides protecting livelihoods of a vast majority of people.

For this purpose, experts considered effective preventive measures, such as vaccines could help taming this menace, alongside existing personal prevention measures. Accordingly, scientists around the world, have are hard to accelerate development and manufacturing of safe and effective Covod-19 vaccines, within the prescribed guidelines. Equally important is the fact these vaccines must be safe with predictable effectiveness- for all age groups.

The good news is, vaccines are now a distinct possibility in the near future, with the positive interim Phase III clinical trial reports pouring in. It gets reflected in the remark of the Director General of the World Health Organization (WHO), on November 23, 2020, at the media briefing on Covid-19. He said: There is now real hope that vaccines – in combination with other tried and tested public health measures – will help to end the pandemic.

Interestingly, amid these reports, a lurking fear of many experts also surfaces – on the impact of possible side effects, that Covid vaccine may cause, besides their medium to long term efficacy in human subjects. But, with the mounting number of deaths, near collapse of the global economy, including India, there isn’t any more time to watch and wait.

Apparently, all governments now want some scientifically relevant vaccines, instead of nothing. This article will deliberate on the one hand – an unprecedented achievement, alongside some critical concerns – voiced even by the Indian Prime Minister. Let me begin with the apprehensions, as expressed by some domain experts on some rough edges, as it were, in the process of its development.

Queries on vaccine dosing, efficacy, safety and testing:

On November 23, 2020, AstraZeneca and Oxford reported interim results of their vaccine with the average efficacy of 70% prevention. This sounded good to many, as it falls within the expectations of above a 50% standard that the FDA had set for Covid vaccines. However, the puzzling part in this result was – bigger (standard) doses of the vaccines were less efficacious. The vaccine was only 62% effective in a group that got two full doses spaced about a month apart. But among about 2,700 people who got a half-dose followed by a full, the number rose to 90%, the report highlighted. This incident prompted several questions about the most effective dose of AstraZeneca and Oxford vaccine, including its safety record and the approach to testing. Consequently, apprehensions surfaced whether the Drug regulators will clear it, based on the currently available data.

It now appears, AstraZeneca ‘s Covid-19 vaccine is ‘headed for an additional global trial as the drug maker tries to clear up the uncertainty and confusion surrounding favorable results in its current study.’ Incidentally, in India - AstraZeneca and Oxford vaccine will be manufactured by Pune-based Serum Institute of India (SII) under a collaborative arrangement. Let me now dwell on a broader as aspect in this space.

Could current Covid vaccines become useless in the future?

There isn’t an iota of doubt that developing Covid vaccine in ten months, which otherwise takes around ten years – is an unprecedented achievement. However, there are several other important areas in this space, where pundits have expressed uneasiness through various articles.
