In news that may frustrate millions of people recovering from the Corona virus, a new study showed that antibodies “evaporate” in the airways quickly after infection!
However, vaccination does its work later and increases its levels dramatically
The results of the study also indicated that taking a second dose of the vaccine after recovering from corona, may be important to protect against re-infection and prevent its transmission.
In this context, Anna Sorensen, who led the research, explained, according to what was reported by the journal “GCL Insight”, that what makes the study unique is that we looked at samples from both blood and airways. This gave us new knowledge of the immune response in places where the virus infects, which is rare in studies, since it is difficult to take samples from the airways, so we knew little about antibody levels in this place compared to blood. The good news!
While I considered that the good news lies in the fact that the antibodies returned quickly after vaccination in those who had previously been infected with the epidemic, it is not only
She explained that scientists found that the levels of antibodies in the airways after two doses of the vaccine were often higher than during the course of the disease, while they found in people In those who were not infected prior to vaccination, levels are much lower or even undetectable!
While Karen Lowry, co-author of the study, noted that “the results of this research showed that the study of blood alone does not reflect the levels of antibodies in The respiratory tract, which is likely to play a major role in neutralizing the virus in places where it is present, therefore supplementing vaccination with a second dose may be important to achieve optimal immune responses and reduce the spread of infection between individuals. The level of antibodies required to protect against infection is not yet known, despite all studies being conducted on this topic.
