rom the CDC comes the latest comparison of our current CoVid vaccines in terms of ability to keep the average Jane or Joe without any medical issues out of the hospital. Once again, Moderna come out on top.
A multi-center study of 1682 vaccinated persons 16 yrs or older and 2007 controls shows that, between March and August of this year, the Moderna vaccine was 93% and significantly more protective against hospitalization than the Pfizer at 88% and the Johnson & Johnson at 71%. The Pfizer shortfall was due to a decline of effectiveness from 91% at 3 months or less to 77% after 3 months.
A subset of vaccinated patients had their anti-CoVid antibodies assayed. Here, the Moderna vaccine again performed better than the Pfizer, particularly for levels of anti-RBD antibodies (4,333 vs 2,950). Both of the mRNA vaccines bested the J&J vaccine with levels that had levels of only 59.
Those vaccinated with Pfizer but particularly with J&J should not only be extra careful with masking, distancing, hygiene, and ventilation but should get in line quickly for a booster.
