Technology to transform health systems: What has the COVID-19 pandemic taught us?

Every country should rationally look at options to boost local manufacturing capacity for essential medical products and smaller nations can evaluate possibilities for maintaining strategic stockpiles.

The ghastly sight of refrigerated trucks parked next to large hospitals in New York City during the peak of the COVID-19 outbreak, was disturbing and thought provoking at the same time.

The city’s morgues were overwhelmed by the bodies coming in and the trucks send by the Federal Emergency Management Agency were the only solution available. Several months later, hundreds of bodies are still lying in those freezer trucks, awaiting a respectable funeral.

This happened at a city which is considered by many as the centre of the free world and the hub of global financial capital. We have seen similar situations playing out in several other developed nations. When the world is at the doorstep of imminent vaccination campaigns, we should be asking ourselves about what went wrong.

More importantly, how can we ensure that the situation does not repeat itself through some other pandemic?

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.
