Omikron vaccinen virker
-
"... 13.5 and 19.6-fold increase in neutralizing geometric titers ..." og "Preliminary laboratory studies demonstrate both Omicron-adapted candidates neutralize Omicron BA.4 and BA.5 though to a lesser extent than they do for BA.1". https://www.pfizer.com/news/press-release/press-release-detail/pfizer-and-biontech-announce-omicron-adapted-covid-19
Altså den nye vaccine virker, men
- målt i reagensglasset
- og knap så godt mod BA.5.
Pfizer og Biontech har ikke fået nogen tilladelser endnu; men blikket er stift rettet derhen:
"Data to be discussed with regulators with goal of rapidly introducing adapted booster to address current and future variants."Det er et svært kapløb.

US køber 105 mio doser af Pfizer og Biontech. Plus option på yderligere 195 mio. Samt mulighed for at få et mix med omikron vaccinen, hvis/når den bliver godkendt. https://www.pfizer.com/news/press-release/press-release-detail/pfizer-and-biontech-announce-new-agreement-us-government
Prisen, 30 usd per dosis, er også interessant.
