Decoding India’s 2021 vaccination challenge

While the government aims to fully vaccinate 94 crore adults in the country by the end of December, it is possible that many do not turn up for the jabs given vaccine hesitancy.

India is expected to end July at about 46 crore total COVID-19 vaccine doses administered over six-and-a-half months, leaving it with an ambitious task to give 142 crores more vaccine jabs over the next five months to fulfil its aim of fully vaccinating all adults in 2021.

Achieving this will depend on three major factors, senior government officials have told News18. One, Bharat Biotech coming to the party and upping its production capabilities of Covaxin as envisioned, as the country is banking on it for a total of 48 crore doses. Two, the Biotech-E vaccine getting emergency use authorisation as the Centre is banking on it for 30 crore doses and has invested Rs 1,500 crore as an advance for “at-risk” manufacturing of the vaccine. Three,  people shedding ‘vaccine hesitancy’ and getting both their doses by December.

The vaccination level of July is expected to be similar to June at about 12 crore doses, despite a new vaccination policy in place since June 21, highlighting that the real issue remains in supply but vaccine hesitancy is a factor too. This may lead to a scenario where most of the adult population could get the first jab by the end of 2021 while the second jab may remain a work in progress.

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.
