In a briefing released Friday, the UK Health Security Agency announced that the Oxford/AstraZeneca, Pfizer/BioNTech and Moderna vaccines all protect against omicron less than they did against delta and that protection from boosters wanes in time. Booster effectiveness generally decreased to between about 60% and 70% protection at two to four weeks after the shot, down to between about 35% and 45% at 10 weeks, depending on the combination of vaccines administered.

Note:NOVAVAX says they may do better - but data not submitted.


>If Merck and Pfizer anti-virials are effective against it.

Regeneron monoclonal antibody NOT effective, but Sotrovimab is.

Pfizer pill for post exposure is effective. Couldn't find Merk data.


>Possible new vaccines - could take as little as 100 days -
>could take more depending on regulatory requirements.

No announcements about making new vaccines yet.


Coming up: Fauci says that daily positives may reach over 500,000 within 2 weeks. It's going to get bad.
