Covishield vs Covaxin Which one is better, Side Effects & Efficacy Rate details are available in this post. Two Covid 19 vaccines are being administered in India. One of them is Covishield of Serum Institute of India and the other is Covaxin of Bharat Biotech. India started its Covid vaccination program in January. More than 17 crores people have been vaccinated in the country so far and crores of doses have been sent to other countries. Two vaccines were approved based on the results of the trial. Experts expressed their opinion about Covishield (Oxford-AstraZeneca Developed) of Serum Institute of India (SII) and Covaxin of Bharat Biotech in collaboration with ICMR. The medical journal ‘Lancet’ has reviewed both vaccines. Both vaccines are safe and are more affective than the World Health Organization (WHO) set standards.
Covishield Vs Covaxin: which is better
Different techniques have been used to make Covishield and Covaxin vaccines. Covaxin has been prepared by deactivating Covid-19. ICMR had given the biotic virus to Bharat Biotech. By neutralizing this virus, Bharat Biotech has prepared the vaccine. Whereas the ‘covishield’ vaccine has been developed by inactivating adenoviruses. The first chimpanzee has been prepared by applying a genetic material of the spine protein of SARS-CoV-2 over an inactive cold-resistant adenovirus. This is the major Difference between Covishield Vs Covaxin you are reading here.
What is Covishield?
The Oxford-AstraZeneca vaccine was developed by Serum Institute of India, the world’s largest vaccine manufacturer in India. The company says that it is making more than 60 million doses of it in a month. This vaccine has been developed from a weak version of the common cold-causing virus in chimpanzee. This was changed to resemble the corona virus.
However, when it is put into the body, it does not cause any disease and when administrated as a vaccine in the body, it causes the immune system to produce antibodies. And when the corona virus infection occurs, it provokes antibodies to attack.Its two doses are given to people at intervals of four to 12 weeks. It is quite easy to store because it requires a temperature of two to eight degrees. Due to this, it can be easily distributed.
How effective is Covishield?
The international clinical trial of the Oxford-AstraZeneca vaccine Covishield states that when people were given one half and then one full dose, it was effective up to 90 percent. However, sufficient and unambiguous figures could not be given to approve the idea of ’half-dose and full dose. Unpublished data showed that keeping a long gap between the first and second doses increases the total effect of the vaccine.
After giving the first dose in a sub-group in this way, the vaccine was found to be effective up to 70 percent.Serum Institute of India (SII), the Indian manufacturer of the vaccine, claimed that Covishield has been found to be highly effective. The third phase data from Brazil and Britain also supports this.

What is Covaxin?
Covaxin is an inactivated vaccine and it means that it is made from dead corona virus which makes the vaccine safe. Bharat Biotech, which manufactures it, has used a sample of corona virus selected by the National Institute of Virology.
Immune cells of the body also recognize the dead virus after vaccination. After this, she prompts the immune system to make antibodies against this virus. A gap of four weeks is maintained between the two doses of this vaccine. It can be stored at a temperature of two to eight degrees.
How effective is Covaxin?
The results of the third phase of the trial of this vaccine show that the vaccine is effective up to 81%.When the Drugs Controller General of India gave emergency approval to the vaccines, its 3rd phase trial was going on. After this approval, people criticized it and doubted the usefulness of the vaccine.According to Bharat Biotech, it has a stock of 2 crore doses of covaxin. By the end of this year, it has a target of making 70 crore doses in its four plants in two cities.
