The physique’s immune system produces antibodies in response to a international pathogen and makes use of them to assist struggle an an infection. All through the pandemic, antibody checks have been used to find out whether or not somebody was beforehand contaminated with the coronavirus.
Now, as Covid vaccines are being administered to tens of millions of individuals, questions have been raised in regards to the function antibody checks may play in figuring out whether or not a vaccine recipient is growing an immune response.

In a press launch on the time, the Swiss diagnostics and pharmaceutical big contended the test could be valuable after someone is vaccinated against Covid.
“Many present candidate vaccines purpose to induce an antibody response in opposition to the SARS-CoV-2 spike protein,” the corporate stated. “Assessments that quantify antibodies to the spike protein may very well be used to measure the extent of that response and monitor that measurement over time.”
Schechter acknowledged there may very well be a job for post-vaccination antibody checks, however he stated “there’s nonetheless much more we now have to study.”
“Sooner or later, it could make sense to have a look at antibodies. It could make sense to have a look at T-cells,” which symbolize one other factor of the physique’s immune response, he stated. “In the mean time, as many individuals ought to get vaccinated as rapidly as attainable, and there is no advice to get a further blood test afterwards,” he added.
