“At the moment, there’s no recommendation to do that. We still have to understand a lot more about the vaccines, know what to measure, how to measure,” Schechter stated on “Closing Bell.”
The physique’s immune system produces antibodies in response to a international pathogen and makes use of them to assist struggle an an infection. Throughout the pandemic, antibody assessments have been used to decide whether or not somebody was beforehand contaminated with the coronavirus.
Now, as Covid vaccines are being administered to thousands and thousands of individuals, questions have been raised concerning the position antibody assessments might play in figuring out whether or not a vaccine recipient is growing an immune response. In medical trials, the vaccines from each Moderna and Pfizer–BioNTech have been proven to be greater than 94% efficient in stopping symptomatic Covid-19.
In December, for instance, Roche was granted emergency use authorization by the U.S. Food and Drug Administration for a take a look at that detects antibodies towards the coronavirus’ spike protein. In a press launch on the time, the Swiss diagnostics and pharmaceutical large contended the take a look at might be worthwhile after somebody is vaccinated towards Covid.
“Many current candidate vaccines aim to induce an antibody response against the SARS-CoV-2 spike protein,” the corporate stated. “Tests that quantify antibodies to the spike protein could be used to measure the level of that response and track that measurement over time.”
Schechter acknowledged there might be a task for post-vaccination antibody assessments, however he stated “there’s still a lot more we have to learn.”
“In the future, it may make sense to look at antibodies. It may make sense to look at T-cells,” which symbolize one other aspect of the physique’s immune response, he stated. “At the moment, as many people should get vaccinated as quickly as possible, and there’s no recommendation to get an additional blood test afterwards,” he added.
