The results of two new research papers published in The Lancet confirmed that just one dose of the Coronavirus vaccine can stimulate a strong enough immune response in people who have already been infected with Corona so that it can protect them from diseases in the future.
In the United States, the vaccine is authorized in two doses, separated by 21 days, to protect against corona, as the first dose prepares the immune system and the second strengthens it.
One of those new papers, according to a report by "CNN", led by researchers at University College London and Public Health in England, included data on 51 health care workers in London, among these workers, 24 were former workers with Corona, and all received Healthcare workers first dose the Pfizer / BioNTech vaccine and then were tested for antibodies after 19 to 29 days.
The researchers found that in those who had a previous natural infection, vaccination increased their antibody levels by more than 140 times.
The other paper, from researchers at Imperial College London and other institutions in the United Kingdom, included data on 72 healthcare workers who were vaccinated in late December, and 21 of them had evidence of previous infection with the Coronavirus.
The workers provided blood samples at the time of receiving their first dose and then 21 to 25 days after vaccination, and the researchers found that people who had previously been infected with the Coronavirus seemed to generate stronger immune responses to a single dose of the vaccine compared to those who had not been infected before.
But despite these results, the researchers stress that people who have previously recovered from the Corona virus, are advised to get two doses of the vaccine when it is their turn.
According to the researchers, if you were not infected with the virus before, the second dose of the "messenger RNA" vaccine would greatly enhance the immunity of T cells, greatly enhance the antibody response, and would undoubtedly provide more complete and long-life protection.
