Immune cells in covid patients: Antibodies remain for 9 months after first COVID infection, claim scientists
98.8 people had antibodies
Scientists tested antibodies in these people once in May and November 2020 after February- March. The study, published in the journal Nature Communications, said that 98.8 percent of people infected in February and March had intact antibody levels in November. The results also showed that antibody levels remained the same in severe and asymptomatic cases of infection. There was no difference in antibodies of both asymptomatic and asymptomatic people.

There is no difference in antibodies of symptomatic-asymptomatic
Antibody levels were tracked using a probe assay based on three analyses. The results showed that there was some decline in antibodies of all types between May and November. So the team also saw cases of increased antibody levels in some people.
Lead author Dr Ilaria Dorigatti, from the MRC Center for Global Infectious Disease Analysis and Abdul Latif Jameel Institute for Disease and Emergency Analytics (J-IDEA) at Imperial, said: ‘We found no evidence that antibody levels differ between asymptomatic and asymptomatic infections. it happens.
He said that it is clear from this that the body’s immune system does not depend on the symptoms of the symptoms of Kovid or the severity of the disease.
Being infected twice increases antibodies
The team found in research that antibody levels increased in some people, indicating that they may have been re-infected with the virus. University of Padua professor Enirco Lavejo said a May investigation showed 3.5 percent of the city’s population was infected. Many people did not even know that they were infected with the virus because they did not show any symptoms i.e. were asymptomatic.
The researchers also analyzed how many more people were infected if one member of the household was infected. It has also been found in the study that in one out of four cases, when one of the family members got infected, the other members also got infected.

Even after making antibodies, follow these rules
This finding confirms that there are large differences in the number of secondary cases generated by infected people. The large differences in how an infected individual can infect others in a population suggest that behavioral factors are important for epidemic control. Experts say that following social distancing, wearing a mask can reduce the risk of infection.
The havoc of Kovid did not reduce
Dr Dorigatti said, ‘It is clear that the epidemic is not over, neither in Italy nor in other countries. I think it is important to continue with the dosage of the first and second vaccines as well as to be careful. The risk of SARS-CoV-2 can be reduced only by following the Kovid protocols.
Earlier also there was research on antibodies
Prior to this research, led by researchers from Washington University School of Medicine at St. Louis and a new study published in the journal Nature, it was found that recovery from mild symptoms of Kovid-19 infection. Even after months of exposure, people have immune cells present in their bodies, which instruct antibodies to fight the virus. Research has found that mild COVID cases provide permanent protection of antibodies to people who have been infected and are less likely to get repeated infections.
