Data collected from 18 states between March and August suggest the Pfizer-BioNTech vaccine reduces the risk of being hospitalized with COVID-19 by 91% in the first four months after receiving the second dose. Beyond 120 days, however, that vaccine efficacy drops to 77%.

Meanwhile, Moderna’s vaccine was 93% effective at reducing the short-term risk of COVID-19 hospitalization and remained 92% effective after 120 days.

That sure would’ve been useful to know back in March…

of course, one wonders why they didn’t know this back in March… June at the latest.

No need for anybody to worry. I got the Moderna.

Delta did not become a thing until much later. Those efficacy statistics are influenced by Delta.

Why use a second string vaccine?

The drop in the antibody levels is the primary problem, otherwise the booster would be irrelevant. They had to have known in their trials that the antibody levels would drop precipitously after 6 months.
