Dealing with Covid-19 can be stressful. A few days ago, this columnist was tested positive for Covid. It was scary at first. The mind plays up your fears and dwells on the extremes. What will happen if I get hospitalized? Will my family be safe? How will we cope if everyone gets it? Luckily for me, the symptoms were mild and I recovered quickly.

Growing up, a visit to the doctor meant travelling a few kilometers by bus or sometimes in an auto rickshaw, waiting in line for a token and then getting a few minutes of facetime with the general physician for a quick diagnosis. Hospital visits were rare and only for serious ailments. Fortunately, I’ve never had to be hospitalized as a child.

Cooped up in my room the past few days, as I learnt more and more about the pandemic, I started panicking. I quickly needed to talk to a doctor. But going to a hospital meant exposing others to the virus. So I quickly Googled Covid care packages at home and found one to my liking. It was being run by a large hospital chain. I called the number they’d advertised and was promptly guided to download their app.

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.
