Of people who got infected with the coronavirus, none have been re-infected from the short term after.
"This has been a black cloud hanging over the potential protection that could be provided by any COVID-19 vaccine and gives real hope that, once a vaccine or vaccines are developed, they will provide long-term protection".
The study also found that staff with antibodies were less likely to have an asymptomatic infection.
A British study has revealed that people who had contracted COVID-19 are unlikely to contacted in again at least six mothers after the first infection.
Some 76 staff without antibodies tested positive compared to just three who had them.
The researchers found a specific cell within the human immune system, the memory B cell, "remembers" infection by the virus, and if challenged again, through re-exposure to the virus, triggers a protective immune response through rapid production of protective antibodies.Читайте также: Diaries of Alan Rickman to be published as a book
It monitored more than 12,000 healthcare workers employed at OUH and found that the chance of infection was hugely reduced in staff who had previously contracted Covid-19. And he considered that this finding makes "expect longer periods of protection" when a vaccine is available.
During the study, 89 out of 11,052 staff without antibodies developed a new infection with symptoms, while none of the 1,246 staff with antibodies developed a symptom infection.
Jeffery, the director of Infection Prevention and Control for Oxford University Hospitals, described the results as an "exciting find" which indicates "at least short-term protection from reinfection." .
"We know from a previous study that antibody levels fall over time", Eyre said.
Three members of staff with antibodies did test positive for the virus that causes COVID-19 but were all well and did not develop symptoms.При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
