Mixing Of Covaxin & Covishield Vaccine: What WE KNOW SO FAR

Indian Council Of Medical Research recently revealed that the mix of two vaccines  ? Covishield and Covaxin, can actually yield better results.

The study was conducted on 18 people & claims that immunisation with the combination of two vaccines is not only safe but elicited better immunogenity.

To further back this with research, Drugs Controller General Of India has given an approval for study and its clinical trials.

The trials now will be conducted by Vellore's Christian Medical College on 300 more people.

The ICMR study said that profile of people who were given mixed vaccine showed that there are similar adverse events to when people are given same doses.

The immunogenicity profile (ability of a foreign substance to provoke an immune response in the body), against variants in people who were given mixed vaccine was superior.

The mix-and-match of the vaccine is not a new phenomena, it has also been done in past, it started with HIV research.

Experts say that mixing vaccine can actually avoid immunity against a vaccine & can elicit a longer immune response.

World Health Organisation have not offered any recommendations on mixing of COVID vaccine.

WHO says that data from mix and match studies of different vaccines are awaited - immunogenicity and safety both need to be evaluated.
