 10 Things to Know About SII’s Covishield Vaccine

There’s much excitement and confusion about the COVID vaccines in India. To help out, the Serum Institute of India has released a fact-sheet with some relevant information abut their vaccine Covishield, like how many doses to take, how efficacious it is, who should avoid the vaccine and more.

FIT breaks it down.

1. Who Will Get the Vaccine?

It has been approved for restricted use in an emergency situation for individuals 18 years of age and above. It is advised that pregnant women weigh the risks before taking the shot.

2. Who Should Skip It?

People with severe allergies would need to be extra careful and should only take the vaccine if recommended by their doctor. People with allergies to the ingredients should avoid the vaccine.


3. Speaking of, What Are The Ingredients?

According to their fact sheet, L-Histidine, L-Histidine hydrochloride monohydrate, Magnesium chloride hexahydrate, Polysorbate 80, Ethanol, Sucrose, Sodium chloride, Disodium edetate dihydrate (EDTA), Water for injection.

4. How Many Doses Are Needed?

The vaccination course includes two doses of 0.5 ml each. It is important that the second dose be given between 4 to 6 weeks post the initial dose to complete the course.

5. Does it Affect Fertility?

6. What Are the Benefits of the Vaccine?

According to the SII pamphlet, in their ongoing clinical trials, Covishield has been shown to prevent COVID infection when two doses are given 4 and 12 weeks apart.

How long does it protect against COVID? This is unclear as of now.

According to the data, Covishield could provide a protective immune response four weeks after the second shot.

7. So, What is the Efficacy?

Based on data from the clinical trials in the United Kingdom, Brazil, and South Africa, giving two full doses of 0.5 ml each has generated an efficacy of 62.10 per cent.

But when the second dose was given 12 weeks after the first does, the efficacy was at 78.79 per cent. This indicates that the 12 week gap is vital.

8. Are There Any Side Effects to Worry About?
