Mazumdar-Shaw, who has been named among the world's 100 most powerful women by Forbes which described her as "India's richest self-made woman", contended that if one looks at the risk-benefit ratio, the risk of not approving a vaccine is far greater than the kind of risks associated with any side- effects.
Safety and efficacy data is pretty good for all the vaccine candidates but the only question unanswered as of now is how long they will give protection, she said.
The risk of waiting to get the answer to the durability question is too high.
Even if the vaccine gives protection for a short-time, it is worth it, she argued.
Terming the pandemic as a "public health catastrophe", Mazumdar-Shaw said there is nothing wrong in government exerting pressure on the regulatory bodies to review the vaccine candidates.
On a certain section of people worried about side-effects of Covid-19 vaccine, she said they should not feel like that, adding, it's not unsafe but the only thing one may not know as of now is how durable it is.
"Right now, as a person, I am not concerned about safety and efficacy (of Covid-19 vaccine). I am more concerned about: Will it protect me long enough?".
"If I were asked whether I will vaccinate myself, I will say 'yes'; because whatever it is, I would like to at least protect myself.
I am one of those fortunate people who actually developed natural immunity because I got Covid-19. But would I recommend that my family takes it? I would say 'yes'," the 67-year-old said.
Mazumdar-Shaw, who has more than four decades of experience in biotechnology, underlined that there is a need to allay fears of people on safety and efficacy of Covid-19 vaccines and to remove vaccine hesitancy.
"It is important to build that reliability and awareness saying that the vaccines are safe, and over time we will know how effective they are in terms of durability", she added.
Noting that "so many" vaccines are being developed because of the pandemic, Mazumdar-Shaw said in an year's time it would be known as to which one is more effective than others.
"... we have no other option. We need to get back to normalcy. I think taking a safe and efficacious vaccine... (even if) with limited protection, you should take it. It's the way I look at it", she said.
