Government begins selecting people for priority coronavirus vaccines

The Times of India said that frontline health and sanitation workers, police officials and elderly people with co-morbidities will get the vaccine on priority.

As the COVID-19 pandemic rages on, several vaccine candidates are in various stages of trials. Here are all the latest updates on coronavirus vaccines and their progress.

India’s coronavirus infections rose by another 62,212 cases over the previous day and a local media report said on Saturday that the government had begun identifying about 300 million people who would be given the vaccine first when it is ready.

The Times of India said that frontline health and sanitation workers, police officials and elderly people with co-morbidities will get the vaccine on priority.

The plan, which is still in the draft stage, aims to cover 23% of the population in the first phase. The final plan is likely to be ready by end October-November, the report said.

The selected individuals will be given an estimated 600 million doses.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

Earlier this month, health minister Harsh Vardhan had said that India hopes to receive up to 500 million doses of coronavirus vaccines by July next year to inoculate about 250 million people.

Officials have said that giving the vaccine to India’s 1.3 billion people will be a mammoth exercise, likely to stretch well into 2022.

India's cumulative tally of coronavirus infections stood at 7.43 million on Saturday, having risen by 62,212 in the last 24 hours, health ministry data showed.

But the number of active infections slipped below 800,000 for the first time in 1.5 months, which the ministry called a significant achievement.

India has recorded the world's second-largest number of cases after the United States and worries have been high that there may be further spikes during the ongoing festival season.
