India likely to vaccinate 60-70% adults by late 2022, most of Africa to wait for COVID-19 vaccine till 2023: Report

The US, Canada, Russia, the UK and most of the European countries are exptected to complete the mass vaccination agsinst COVID-19 at the earliest.

Despite the rollout of COVID-19 vaccines in a number of countries, the global vaccination timeline would extend into 2023, according to a new report by the Economist Intelligence Unit (EIU).

India, which is currently vaccinating its citizens faster than any other country, is expected to inoculate 60-70 percent of its adult population not before late 2022, the report claimed.

China is also expected to complete the mass inoculation programme by late next year. Both the countries, despite being ahead in their vaccination developments, would require a larger time period for mass immunisation due to their populations of over 1.3 billion.

Most of Africa would lack widespread access to vaccines till early 2023, the report showed.

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.
