#COVID #Immunity #Vaccination #AntibodyTitres are not necessarily an indicator of COVID immunity. A lot of people are posting messages worried about not demonstrating antibodies post-vaccination. This is a myth that needs to be addressed. Follow this thread......
There are various types of antibody tests, directed against specific components of the virus. Just bcoz antibody to 1 component is absent, doesn't imply lack of the immunity, coz we may have other COVID neutralising antibodies we haven't been tested for!
+ there is something called cell-mediated immunity which doesn’t show up in antibody tests. Moreover, antibodies may be present, in memory cells in the bone marrow and not in the circulating blood. They may only be recruited to fight when exposed to the virus!
