Molnupiravir, an oral antiviral pill approved for treating Covid-19, has been questioned over its safety, but Indian health experts say the benefits outweigh the risks in the case of high-risk patients.

On Monday, health professionals treating coronavirus patients across the country reported that the Covid antiviral drug has reduced hospitalisation by 30 to 50 percent, as well as severity of the disease.

Developed by US-based drug company Merck, Molnupiravir is approved by the US Food and Drug Administration against Covid-19. It is approved by the UK Medicines and Healthcare Products Regulatory Agency (MHRA) for the treatment of mild-to-moderate Covid-19 in adults with a high risk of progression to severe disease, mainly those with pre-existing (comorbid) conditions.

"The question is can a medicine cause cancer in humans after using it for only five days? There should not be any hesitation in using the drug among patients above 45-50 years with co-morbidities. "It's a trade-off and it's more in favour of benefits." Dr Vasant Nagvekar, a task force member, said the drug should be used at a clinician's discretion.

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.
