India witnessed a record single-day spike of 75,760 COVID-19 cases, as per the health ministry's 8 am update on August 27. The country has been reporting the highest daily rise in fresh cases globally, even as the death toll due to the infection has gone past the 60,000-mark.

Amid the precarious pandemic situation and rising number of cases, students across the country have been demanding postponement and cancellation of several examinations for fear of contracting the infection.

While many have cited the lockdown and restrictions on transport as reasons that would prevent them from reaching their centres, others have said they fear getting infected and putting other vulnerable family members at risk. However, the government has maintained that proper social distancing measures will be implemented to ensure the safety of students.

Globally, over 2.41 crore confirmed cases of COVID-19 have been reported and more than 8.24 lakh people have died due to the infection.

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.
