COVID-19 crisis | Pharma lobby calls for increased vaccine sharing

An estimated 11 billion vaccine doses could be produced by the end of 2021, compared with 2.2 billion at the end of May, according to the groups that are based in Europe and the United States.

Leading pharmaceutical organisations pressed Wednesday for urgent measures to share coronavirus vaccines globally and inoculate the world's entire adult population by the end of the year.

While advanced countries have made progress with vaccination programmes, shots "are not equally reaching all priority populations worldwide", eight major drug organisations and associations noted in a joint statement.

"Manufacturers, governments, and non-governmental organizations must work together to take urgent steps to further address this inequity," they said.

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.
