Efficacy Rate

To understand the efficacy rate of these vaccines, several trials are done before launching them for vaccination.


Covaxin has shown a good efficacy rate in the results of its third phase. It has an efficacy rate of about 81% according to the researchers and developers. As the vaccination drive is on, many more efficacy results are coming up. In the recent results, it has been found that after the second dose, people can have an efficacy rate of 78% to 95% depending upon the already existing diseases that a particular person may have.


Covishield is known to come up with even better results when it comes to its efficacy rate. The vaccine has been tested and trialed at different parts of the world and the efficacy rate has come up as about 90% that is much more than satisfactory. Similar to Covaxin, an even clearer efficacy result is coming up from the vaccination drive. According to this result, Covishield can be efficient from 70% to 90% in different people, depending upon the diseases that they may have, the lifestyle that they lead, and the precautions that they are maintaining against Covid.

Both Covaxin and Covishield can be stored at a temperature of +2 degree Celsius to +8 degree Celsius. This is the average temperature that is available in general household refrigerators.

Vaccine Price


Currently, Covaxin is being used only for Indian citizens. The price of the vaccine will depend upon the place from where you are getting vaccinated. If you are getting your slots booked in a Government hospital, the vaccination is absolutely free, irrespective of whom you are. But if you are booking a slot in a private hospital, you have to bear the cost of the vaccine. The price of the vaccine will vary from one hospital to another. For example, one of the known hospitals of India Appolo is offering each dose of Covaxin at Rs. 1250/-. On the other hand, there are also some other private hospitals that are charging even Rs. 1500/- for the same booster.


Similar to Covaxin, even Covishield is available for free at Government hospitals. But if you are visiting a private hospital, you have to bear the cost. But as per the records, it has been noticed that private hospitals are charging comparatively lesser for Covishield than Covaxin. Let us take the same example of Apollo that we took for Covaxin. Apollo is charging Rs. 825/- per dose for Covishield.



Covaxin is an intramuscular vaccine that is injected into the upper arm region of any hand. An amount of 0.5ml is injected into the body per dose. Once the first dose is injected, the second dose has to be injected with a time period of 4 to 6 weeks.


Similar to Covaxin, Covishield is also an intramuscular vaccine. Again similar to Covaxin, a number of 0.5ml per dose are injected into the upper arm region of any hand in the case of Covishield. The only difference between both vaccines is the gap between the two dosages. It is mandatory to keep a gap of 12 to 16 weeks or 84 days between the first and the second dose of Covishield.
