Recent news indicates a CDC signal indicated a possible concern with the Pfizor booster. Several other monitors do not duplicate this finding and CDC continues to encourage continued usage of this booster. While I have absolutely no training in this area, I did want to know the significance of the "adverse event signal". The following is what I found. The 3rd paragraph seemed a bit undefined (sentence in Bold Red). Same data used but with a different methodology could not replicate.


"The signal was detected in the Vaccine Safety Datalink, a collaboration involving the CDC and about a dozen health-care organizations with electronic health records on 12 million people. As part of routine monitoring for possible adverse events, officials noticed late last year that they were picking up indications of higher-than-expected stroke risk, officials said.

Among about 550,000 people 65 and older who had already been vaccinated and received a booster dose of the Pfizer bivalent vaccine, 130 people had strokes in the first three weeks after getting the shot. No deaths have been reported. That finding raised a question because it suggested that people who received the bivalent were more likely to have an ischemic stroke in the 21 days following vaccination compared with Days 22 through 44 following vaccination.

The findings prompted officials to look for similar findings. CDC officials conducted a different analysis in the Vaccine Safety Datalink system, using the same data but different methodology, and were not able to replicate the finding. Officials also searched other systems, including those of Medicare, the Department of Veterans Affairs and Pfizer’s global surveillance network. Regulators in other countries, including Israel, also were consulted, but no evidence of similar findings emerged, the officials said."
