Covaxin And Covishield, How Different Are They From One Another?

Updated: Jul 6




Which vaccine should I take?

If you are not yet vaccinated, our advice, just take the jab of whichever of the approved vaccines that's available at the vaccination center you are at.


Vaccines save lives, and presently that’s your only protection against the dreaded coronavirus. Vaccinate and keep yourself protected. A vaccine gains approval of being safe for human use after undergoing numerous stringent formalities. So either of the vaccines are tested and are safe.


Covaxin and Covishield have received approvals for use in India.

If you are an Indian who takes pride in encouraging products indigenously developed in India, Covaxin is your ideal choice, otherwise there’s nothing left to ponder about between the efficacy of the two vaccines, just take the jab!


If you have recently recovered from a Covid infection, then you can refrain from taking vaccination for a period of almost 3 months.


Understanding Covaxin & Covishield

Covaxin

1. Manufactured by Bharat Biotech in India, and developed by them in association with ICMR and NIV.

2. It is an inactivated viral vaccine.

3. Uses Whole-Virion Inactivated Vero Cell-derived technology.

4. The vaccine contains dead covid viruses that are not capable of infecting the person, but the vaccine is capable of triggering the immune system to create a defence mechanism against the actual virus that causes covid.

5. The same technology is used to develop vaccines for rabies, polio, Japanese encephalitis, etc.

6. Second dose is administered 4-6 weeks after the first dose.


Covishield

1. Developed by Oxford-Astrazeneca and manufactured by Serum Institute of India in India.

2. It is a recombinant vaccine.

3. Uses a Viral Vector platform.

4. The vaccine utilizes a chimpanzee adenovirus ChAdOx1 with suitable modifications enabling it to carry the Covid-19 spike protein. The virus does not infect the receiver of the vaccine but stimulates the immune system to develop response against the actual virus that causes covid.

5. The same technology was used to develop vaccines against ebola, etc.

6. Second dose is administered 12-16 weeks after the first dose.
