Indian Medical Association (IMA) president JA Jayalal has said that the public should not worry about the efficacy of Covid-19 vaccines as there is evidence to prove their credibility.
“The people should not worry much about the safety and efficacy of Covid-19 vaccines as enough evidence is available to prove their credibility,” a report quoted JA Jayalal as saying.
He said vaccines are never 100 per cent protective and efficacious at any time.
Vaccines help the human body to overcome an infection, but herd immunity sets in to control the spread of a virus.
India has approved two Covid-19 vaccine candidates, Covishield by the Serum Institute of India and Covaxin by Bharat Biotech.
Covaxin has been approved for restricted emergency use in a clinical trial mode.
The mass immunization drive will begin in India start on January 16.
“The trials have proved the safety of the Covid-19 vaccines and they trigger an immune response in the human body. The technology of harnessing vaccines from inactivated viruses is proven science,” Jayalal said.
While the human body develops fewer antibodies during some infections, it may develop more during certain infections.
Again in case of some infections, the body may never develop antibodies.
“Covid-19 vaccines are producing antibodies and it’s enough at this stage,” he said.
Jayalal also said that the vaccines would be effective against the new mutant strains as well.
Meanwhile, the apex association of modern medicine practitioners in India has extended their support to scientists in endorsing the safety and efficacy of both indigenously produced vaccines to defy rumours circulating on social media.
