Data Says COVID Booster Only 37% Effective Against Omicron–So Why Are The FDA And CDC Pushing It?

A new study(that has not been yet peer-reviewed) found that a booster shot is only 37% effective against the Omicron variant. 

This calls into question why the FDA and CDC are pushing it.

Back in 2020, the FDA said they would only approve a vaccine that at least had 50% effectiveness.


NEW – Canada: New data from Ontario suggests a 3rd mRNA dose (“booster”) has a “vaccine effectiveness” of only 37% for Omicron. In 2020, the FDA said they would not accept vaccine efficacy less than 50%. Yet the FDA and CDC advising a “booster” for Omicron.



Results We included 3,442 Omicron-positive cases, 9,201 Delta-positive cases, and 471,545 test-negative controls. After 2 doses of COVID-19 vaccine, vaccine effectiveness against Delta infection declined steadily over time but recovered to 93% (95%CI, 92-94%) ≥7 days after receiving an mRNA vaccine for the third dose. In contrast, receipt of 2 doses of COVID-19 vaccines was not protective against Omicron. Vaccine effectiveness against Omicron was 37% (95%CI, 19-50%) ≥7 days after receiving an mRNA vaccine for the third dose.

Conclusions Two doses of COVID-19 vaccines are unlikely to protect against infection by Omicron. A third dose provides some protection in the immediate term, but substantially less than against Delta. Our results may be confounded by behaviours that we were unable to account for in our analyses. Further research is needed to examine protection against severe outcomes.
