In May, the Independent Panel on Pandemic Preparedness and Response submitted its report to the World Health Organization (WHO), to be presented at the 74th World Health Assembly (WHA).

The panel, co-chaired by Ellen Johnson Sirleaf, former President of Liberia and Nobel Laureate, and Helen Clark, former Prime Minister of New Zealand, has high-profile members, including former Presidents, economists, health bureaucrats and activists. They reviewed documents, heard from experts, held round-table discussions, organised town-hall meetings and received open submissions from the governments and civil society. The final report titled ‘Covid19: Making it the last pandemic’ is a seminal work on the socio-economic and healthcare perspectives of the COVID-19 pandemic.

Multi-Dimensional Assessment

The report goes beyond the usual statistics about mortality, morbidity and loss to the economy; and acknowledges the social impact of the pandemic. The pandemic kept 90 percent of the children out of schools at its highest point. It increased the demand for support services for gender-based violence by five times and placed 10 million girls at risk of an early marriage.

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.
