#USA, January 20, 2023 – The US Centres for Disease Control and Food and Drug Administration have identified a potential risk of ischemic stroke in the elderly relating to the new Pfizer BioNTech Vaccine Bivalent.  Shockingly, despite the admission, the CDC is not advising there be any changes in vaccination methods, saying at this time it is not necessary.

The safety concern was flagged by the CDC’s Vaccine Safety Datalink, a 33 year old near real-time surveillance system which uses electronic health data to monitor the safety of vaccines.

Based on data provided by the VSD’ CDC officials launched an investigation into whether people 65 and older who have received the Pfizer-BioNTech COVID-19 Vaccine Bivalent were more likely to have an ischemic stroke in the 21 days following vaccination.

Ischemic strokes are the most common type of stroke and tend to happen when a blood clot blocks the flow of blood and oxygen to the brain.

Early in the administration of COVID-19 vaccines it was young people who were being warned off of vaccines because of a risk of blood clots.

The agency said multiple checks had been done with at least four other surveillance systems including government and private agencies; none have flagged the safety concern, nor has any other country flagged the finding as an issue.

Based on the assessments the CDC advised this, “Although the totality of the data currently suggests that it is very unlikely that the signal in VSD represents a true clinical risk, we believe it is important to share this information with the public— No change in vaccination practice is recommended. CDC continues to recommend that everyone ages 6 months of age and older stay up-to-date with COVID-19 vaccination; this includes individuals who are currently eligible to receive an updated (bivalent) vaccine.”

The CDC indicated that the moderna vaccine has not shown any sign of the risk at all.
