In addition to wanting at the security of the vaccines, the researchers also gathered blood to evaluate antibodies to the coronavirus. Some mixtures of distinctive vaccine manufacturers led to a a bit reduce level of antibodies, and a a bit bigger stage in other conditions. But the researchers did not suspect that any blend of a flu and Covid vaccine would result in a decrease usefulness than every single supplied independently.
