How many times are we going to go over this? > There was a difference in the antibody levels from samples taken within 2 months and at 6 months post second dose where the 6 months antibody levels were sharply lower > In contrast, convalescent sera did not exhibit a correlative between time and antibody levels > Hence, the data suggests that the antibody levels of convalescent sera did not decline significantly for 8 months post infections, whereas the ultrahigh RBD antibody levels achieved with mRNA vaccines could be subject to a more rapid decline. > there was no trend of decreasing RBD antibodies in those with natural immunity for up to 9 months in our dataset. > In comparison, while mRNA vaccines resulted in much higher RBD antibody levels than natural infections, this hyper-elevated level appeared to be less stable with samples at 6 months past the second dose. While our work is still very preliminary, there is a recent study observing similar rapid decline in RBD antibody within 6 months of BNT162b2 vaccine Just legalize natural immunity already, this is ridiculous.
