National Desk: A study has revealed that only one dose of the anti-Kovid-19 vaccine may be effective in those previously infected with the corona virus. Researchers have done this study on the UK and South African variants of the virus but believe that their investigation may also apply to the Brazilian (p.1) and Indian (b.1.617 and b.1.618) variants. The study has been published in the journal Science, which states that people who have not been previously infected with Kovid-19 and have taken only one dose of the vaccine may have an immune response to the forms of the corona virus. .
Researchers at Imperial College London, Queen Mary University, London, and University College London have studied UK health workers taking the first dose of the Pfizer / Bioentech vaccine at Barts and Royal Free Hospitals. They found that those who had previously had an infection and had minor symptoms or no symptoms at all, increased protection against the Kent and South African forms of the virus after taking the first dose of this vaccine. At the same time, people who have not been ill with Kovid-19 before, after taking the first dose of the vaccine, the immunity was less strong and they were at risk of the forms of the virus.
Rosemary Boynton, professor of immunology and respiratory medicine at Imperial College London, said that her study showed that people who had taken the first dose of the vaccine and had not previously been infected with SARS-Cove-2 , They have not received complete protection from virus forms. He said that this study underscores the importance of taking a second dose of vaccine to give people complete protection against the corona virus.
