Bill Gates, the virus and the quest to vaccinate the world

If the initiative, aided by Bill Gates’ fortune and focus, manages to help protect the world’s poor from a virus that has already killed more than 1.3 million people, it will affirm the strategies he has promoted in his philanthropic work.

The head of one of the world’s largest vaccine manufacturers had a problem. Adar Poonawalla, chief executive of the Serum Institute of India, needed $850 million so he could begin producing doses of promising coronavirus vaccines for the world’s poor.

Poonawalla calculated that he could risk $300 million of his company’s money but would still be more than $500 million short. So he looked to a retired software executive in Seattle.

Bill Gates, the Microsoft founder turned philanthropist, had known Poonawalla for years. Gates had spent billions to help bring vaccines to the developing world, working closely with pharmaceutical executives to transform the market. In doing so, he became the most powerful — and provocative — private player in global health.

By the end of their conversation this summer, Gates had made a promise: The Bill and Melinda Gates Foundation would provide a $150 million guarantee so the Indian factory could move ahead with production. By September, the foundation had doubled its commitment.

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.
