In a wide-ranging interview with Moneycontrol, one of India's most respected surgeons, Dr Devi Shetty laid down a three-point plan to hasten vaccination, ramp up medical workforce, and prepare for the third wave, as the second wave of coronavirus ravages India. He also spoke about why no country in the world could have managed the caseload India is reporting, even as he lauded the government for its efforts to get oxygen to hospitals as cases surged in April. Shetty has been named as the head of the task force set up by the Karnataka government to prepare for the third wave of the pandemic.

Q: Many experts believe that the worst may be over soon for India as far as the second wave of Coronavirus is concerned and that May-end, the first week of June is when there will be some respite. Based on what you see today, when do you believe there will be some light at the end of the tunnel?

A: I'm not an epidemiologist or a virologist, I'm only a heart surgeon. But to be realistic, we should be preparing ourselves for this fight to continue till at least the middle of next year, because this is how long generally that each pandemic lasted in the past. But the intensity will come down. Generally, what we noticed was that the pandemic second wave is always severe, the third wave will not be as severe as the second wave.

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.
