Covid-19 vaccines train your immune system to fight the n-coronavirus
Covishield, Covaxin, and Sputnik V have been approved in India
Covaxin effectively neutralises the double mutant strain in India, says ICMR
A vaccine teaches your immune system to battle pathogens – and this is the goal of the Covid-19 vaccine. It helps you develop antibodies to better fight Covid-19, should you be exposed to the virus. Here are some key facts about Covid-19 vaccines in India.
While the entire procedure of vaccine development can take up to 10-15 years, the Covid-19 vaccine was developed in less than a year. This was largely possible due to global cooperation and funding. Further, SARS-CoV-2, the virus that causes Covid-19, is not a new virus and there already existed significant progress in vaccine technology.

Below are the three Covid-19 vaccine types in India,
Bharat Biotech, with a rich portfolio of 16 vaccines to date, developed India’s first indigenous Covid-19 vaccine – Covaxin. This is an inactive Covid-19 vaccine made using dead coronaviruses and has an efficacy of 81%. It is administered in two doses, four weeks apart. Recently, the ICMR has declared that Covaxin neutralises against multiple variants of the Covid-19 virus and effectively neutralises the double mutant strain.

This Covid-19 vaccine developed by Oxford-AstraZeneca is being manufactured by the Serum Institute of India. It consists of a common cold virus extracted from chimpanzees. This Covid-19 vaccine schedule consists of 2 doses, taken 4 to 8 weeks apart. The vaccine has an efficacy of ~63%, but with a longer gap between the two doses, the efficacy is reported to increase to 82-90%.
The Russian-made Covid-19 vaccine, Sputnik-V, is similar to Covishield and was recently approved by the Indian government. Sputnik-V has reported an efficacy of 92% as per research published in The Lancet, a renowned medical journal. This Covid-19 vaccine, unlike others, uses two different variations of the vaccines, injected 21-days apart. This provide a greater boost to the immunity system.
During the second wave of the coronavirus, the Government of India changed the Covid-19 vaccine eligibility to include everyone above the age of 18 from 1 May 2021. However, a shortage of vaccines has disrupted the vaccination drive. Therefore, you must adhere to preventive measures, including staying at home, wearing a mask, washing your hands at regular intervals, and maintaining physical distance. Moreover, if you have a Covid-19 vaccine scheduled and are unnerved by myths, look up sound Covid-19 vaccine facts and dispel misinformation.
