From 100% effective, to there's still a chance you get Covid and die, to maybe 6 months of protection, now down to needing a booster every three months. Disappointing.

The pfizer vaccine trials ended over a year ago[1]. Why are we only finding out about the reduced protection now? If the vaccine only works for three months, we should have known about that 10 months ago.

Is this really the first time you’re hearing this news? It’s been clear and supported by data for months.

This is the first time I'm hearing 3 months. Pfizer themselves said 6-12 months a few months ago[1], and have said 18 months as recently as Sept 30[2]. To be off by a factor of 6 in such a short time is, as I said, a PR disaster.
