Scientists in Pfizer company research found that the vaccine remains 90 percent effective even after 21 days. Scientists said that the risk of infection could be doubled in 8 days after taking the first dose of this medicine. Learn why?
New Delhi: Pharmaceutical manufacturer Pfizer has withdrawn permission to use emergency in India. Pfizer petitioned the Drugs Controller General of India (DCGI) to approve the emergency use of the corn vaccine.
Pfizer was the first pharmaceutical company at the time it applied for approval for emergency use. A company spokesperson said, “The company has withdrawn the emergency use.” Pfizer’s drug has been approved for emergency use in Britain and Bahrain.
In such a situation, the question is arising in everyone’s mind that why the approval for its use was withdrawn and how effective this medicine is. Talking about Pfizer Koranavias vaccine, according to one study, one dose of this vaccine remains safe and effective even after three weeks.
21 days after vaccine effector
Researchers at the University of East Anglia (UEA) said the vaccine was made by two companies, Bioentech and P-Pfizer. This vaccine remains effective even 21 days after giving the first dose of this vaccine. Also, after the study, it was found that even after 12 weeks of giving the first dose of corona vaccine, its effect remains 76 percent and prevents the disease from spreading by 67 percent.
Scientists found during the study that the vaccine remains 90 percent effective even after 21 days, but immunity may decline after nine weeks. It is worth noting that scientists have also said that the risk of infection can be doubled in 8 days of giving its first dose, because people feel that now they have got corona vaccine, now they will have nothing . Due to this people do not take vigilance.
At the same time, the University of Oxford announced on 2 February that its effect remains up to 82.4 percent when two doses of this vaccine are taken after a gap of three months. The happy thing in this study is that people who have been given vaccination have not only recovered, but this vaccine has also reduced the chances of spreading infection on them.
