Boosted CoVid Vaccinations Essential For Omicron Protection
Vidcast: https://youtu.be/WCT_cC-l2FA
Boosting of CoVid-vaccination induced immunity is necessary to have any chance of preventing an Omicron infection. This the conclusion of German infectious disease researchers after studying the effects of serum from subjects vaccinated with either Pfizer or Moderna vaccines and boosted with either Pfizer or a natural CoVid infection.
This first plot shows the relative protective strength of anti-CoVid antibodies when tested against the Delta variant in grey or the Omicron variant in red. The two shot Pfizer regimen produces little protection against Omicron. Boosting the immunity with a third shot of Pfizer using various doses or a natural infection does produce protection in 1/3 to 1/2 of patients.
The second plot shows that 2 shots of Moderna is similarly ineffective against Omicron compared with Delta. Adding a booster of Pfizer offers protection in 7 of 9 patients.
We don’t know yet how serious an Omicron infection can be. With hospitalization and deaths rising, we suspect that the news is not good. Now is the time to develop as much CoVid immunity as you can with at least 3 shots of either the Moderna or Pfizer vaccines.
