re: Three more studies show negative vaccine efficacy.

quote:

---

Pfizer vaccine effectiveness at 53.8% and Moderna at 65% against Delta after three months. They reported that a third dose of Pfizer got vaccine effectiveness against Omicron back up to 54.6%, at least for a month.

And just like that - up to date means quarterly.

For now, until years of science tells us otherwise.

With Omicron, the reports of negative efficacy are becoming impossible to ignore
