An ischemic stroke happens when a blood clot prevents blood from passing through the arteries to the brain. The VSD detected the early signal in the bivalent booster, which is designed to inoculate against the original strain of the disease as well as omicron subvariants.
However, Pfizer and BioNTech have stated that “there is no evidence to conclude that ischemic stroke is associated with the use of the companies’ COVID-19 vaccines.” Pfizer also said that health officials have not found similar findings on numerous other monitoring systems in the U.S. and across the world. The signal was not identified in the Moderna version of the vaccine.
The CDC has stated that the rapid-response investigation of the signal in the VSD raised a question of whether people aged 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 compared with days 22-44 following vaccination.
The Biden administration has been pushing for elderly Americans to stay up to date on their booster shots given that their demographic is at the greatest risk of developing severe health complications from the virus. The Food and Drug Administration (FDA) has reassured the public that the flagged signal in the Pfizer booster may not be cause for alarm as it appears to be more of a statistical anomaly. An FDA official stated that “We have looked at the totality of the evidence and there are no concerns at this time that this represents a true safety signal. Like with a radio, you are going to hear some static in the background.”
It’s important to note that, as with any vaccine, monitoring systems are in place to detect any potential side effects or safety concerns. The CDC and FDA are actively investigating this potential concern, but it is important to not jump to conclusions without all the information. As always, it is important to consult with a healthcare professional before making any decisions regarding vaccinations.
In summary, the CDC is investigating a potential safety concern linked to the use of the updated Pfizer Covid vaccine booster in seniors after detecting an early signal of ischemic stroke in the bivalent booster. However, Pfizer and BioNTech have stated that there is no evidence to conclude that ischemic stroke is associated with the use of the companies’ COVID-19 vaccines.
