WHO chief Tedros Adhanom Ghebreyesus discussed the issue of the emergency use listing of Bharat Biotech’s COVID-19 vaccine Covaxin and resumption of supplies of the Serum Institute of India-manufactured AstraZeneca vaccine to the COVAX facility among other topics during a telephonic conversation with Health Minister Mansukh Mandaviya.

Had a call with @mansukhmandviya, India’s Health Minister, to discuss #India’s ongoing #COVID19 vaccination programme; the need for a global pandemic agreement; digital health; & traditional medicine. We welcome India’s support to strengthen WHO, incl. via flexible, sustainable financing, Ghebreyesus tweeted on Tuesday.

The WHO Director-General said that he also discussed with Mandaviya vaccine equity issues: the resumption of SII/AstraZeneca vaccine supplies to #COVAX; the Covaxin Emergency Use Listing process; and technology and license sharing through C-TAP.

COVID-19 Technology Access Pool (C-TAP) was launched in May last year for facilitating timely, equitable and affordable access of COVID-19 health products by boosting their supply.

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.
