After 7 months, overall vaccine effectiveness preventing any CoVid infection drops from a peak of 95-96% to 70% for Pfizer and 82% for Moderna.  Over a 5 month period, vaccine effectiveness for the J&J vaccine drops from a peak of 79% to 64%.  Public health investigators at the University of North Carolina tabulated state-wide data on over 10 million persons from December, 2020 to September, 2021.


Looking at protection against hospitalization and death from CoVid: for Pfizer the number dropped from a peak of 96% to 88% at 7 months; for Moderna, a peak of 98% to 92%; and for J&J, a peak of 90% to 80% after 5 months. 


These vaccines are remarkably effective over time, but less so against the Delta variant which increased over the time of the study.  Bottom line: you receive optimal protection, especially if you are in a high risk group, from a booster dose of CoVid vaccine.
