Paul, from what i read, i believe on the Moderna website (i will try to find it and post later if i do), .....
overall effectiveness for Moderna was 94.1%
Efficacy for under age 65 was 96%
Efficacy for age 65 + was 85%. This group was 25% of the cohort of the phase 3 trials
Prato, I just reviewed the FDA Briefing Document (12/17/20) on the Moderna vaccine and your numbers are very close. The final efficacy analysis showed:
Age 18 - 65: 95.6%
Age 65+: 86.4%
The other good news from the final efficacy analysis was that there were ZERO "severe" COVID cases in the trial...in any age group. So while us old folks may not be totally immune to the virus there is a great chance that even if we get it post-vaccine we will not get dangerously ill.
