Johnson & Johnson’s one-dose corona vaccine has been approved by the government for emergency use in India. Now India has 5 vaccines for Corona. This will give more strength to the country’s collective fight against Corona. Johnson & Johnson dosages will be available in India in the next two weeks.
This is a single dose vaccine and is being seen as a boon for a country with a large population like India. So far 50 crore people have been vaccinated in India and about 50 crore more vaccines are needed. So far, Covaxin, Covishield, Sputnik, Moderna and now Johnson & Johnson will also be available for use in the country.
Covaccine is a completely indigenous vaccine. It is being made by Bharat Biotech, while Covishield is produced by Oxford-AstraZeneca, Serum Institute is making it in India, while Sputnik is made by Gamalea Institute in Russia with funding from Russian Direct Investment Fund, its production in India Hyderabad based Dr. Reddy’s Lab is doing it. Moderna Vaccine and Johnson & Johnson are vaccines of American companies.
The vaccine has proved to be up to 92 percent effective against corona, while the efficiency of Covishield is between 62 percent and 80 percent. However, based on the data received so far, it is believed that if two doses of Covishield are administered with an interval of two to three months, then this vaccine is up to 90 percent effective. Whereas, Sputnik’s efficiency is up to 91.60 per cent, Moderna’s has also been recorded up to 95 per cent whereas Johnson & Johnson’s now available for use in India has also registered up to 95 per cent.
Covaccine is made in the traditional way, that is, in this, the dead virus is inserted inside the body, due to which the body recognizes the virus and makes antibodies against it. At the same time, both Covishield and Sputnik are vaccines based on adenovirus. The only difference is that both the doses of Sputnik are made from different viruses and there is no difference between the two doses of Covishield, all three vaccines are of both doses.
The maximum difference between the two doses is in Covishield, while the least is in Sputnik. A gap of 12 to 16 weeks has been kept between two doses of Covishield. Two doses of Covaccine are being administered at an interval of 4 to 6 weeks. At the same time, there is a gap of three weeks i.e. 21 days between two doses of Sputnik, whereas there is no such problem with Johnson & Johnson. The vaccine process is complete with one dose and this vaccine can prove to be a boon for a country with a large population like India.
