We will have an abundant supply of Remdesivir by the second week of May: Biocon chief Kiran Mazumdar Shaw

Biocon Executive Chairperson Kiran Mazumdar Shaw says scarcity of critical anti-COVID-19 drugs Remdesivir and Itolizumab will end in 4-6 weeks as suppliers like her own company ramp up output that fell when the pandemic was receding. She said market pricing of vaccines is a must for the much-needed acceleration in inoculation.

The second wave of COVID-19 has hit India with ferocity. Desperate pleas for help abound in social media as families struggle for hospital beds, oxygen, and drugs used to treat the virus. Biocon, which manufactures two critical drugs, Remdesivir and Itolizumab, is ramping up manufacturing to meet the sudden surge in demand. Its top boss Kiran Mazumdar Shaw spoke to Moneycontrol on the factors that led to India dropping the ball in its fight against COVID-19 and the solutions ahead.

Q: First of all, how has the last week been for you? The news flow has been very alarming.

Kiran: It has been a very, very difficult time for us, in many ways. This whole situation is so alarming. And for someone who is manufacturing two very critical drugs that are needed to basically deal with this current crisis of the second wave, it has been non-stop trying to ramp up production, catering to demand. There's a sudden surge of demand. And it's been really very challenging to try and meet it, and very alarming to see that hospitals are full, patients are struggling, these drugs are given in a hospital setting, so you can understand the kind of gravity of the situation.

Q: In fact, I saw a lot of requests on social media for Remdesivir as well as Itolizumab. There also seems to be panic because hospitals are now asking many patients to source this on their own

COVID-19 Vaccine
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.
