COVID-19 update | Over 200 world leaders urge G7 nations to help vaccinate the world's poorest

A letter warns that the leaders of the UK, US, France, Germany, Italy, Japan and Canada must make 2021 a turning point in global cooperation because fewer than 2 per cent of people in sub-Saharan Africa have been vaccinated against COVID-19.

Some 230 world leaders, including former presidents, prime ministers and ministers have backed a campaign urging the G7 countries to help vaccinate the world's poorest from low-income economies against COVID-19 by paying two-thirds of an estimated $66 billion required.

A letter, seen by the Guardian' newspaper ahead of the G7 summit to be hosted by UK Prime Minister Boris Johnson in Cornwall from this Friday, warns that the leaders of the UK, US, France, Germany, Italy, Japan and Canada must make 2021 a turning point in global cooperation because fewer than 2 per cent of people in sub-Saharan Africa have been vaccinated against COVID-19.

The letter, whose signatories include former British Prime Ministers Tony Blair and Gordon Brown, argues the investment needed is affordable for the world's richest economies and vital to stopping the spread of new coronavirus variants that could undermine current vaccines.

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.
