Did CDC + FDA Warn Of Stroke From Pfizer Vaccine?!

Did the CDC and FDA warn that the new Pfizer bivalent vaccine can cause a brain stroke?!

Take a look at the viral claims, and find out what the facts really are!


Claim : CDC + FDA Just Warned Of Stroke From Pfizer Vaccine!

People are sharing various articles about a new CDC and FDA notification on the new Pfizer bivalent COVID-19 vaccine, together with alarming comments, like:

CDC/FDA lied to the American public & Big Pharma lied , withheld information…Now because of the fear of the Republican House the Truth starts to come out … CDC, FDA see possible link between Pfizer’s bivalent shot and strokes

BREAKING: The CDC is now investigating a possible link between Pfizer Covid Vaccines and strokes

Time to sue everyone who pushed a vaccine. Your employer. The government. Retail stores. Everyone needs to be held accountable


US says Pfizer’s bivalent 💉 may be LINKED to a type of brain stroke in older adults


You know there’s a real & dangerous problem when BOTH the CDC & FDA raise a safety issue

They’re covering themselves BUT you’ve been WARNED


Truth : CDC + FDA Did Not Warn Of Stroke From Pfizer Vaccine!

It is true that the CDC and FDA released a notification about the new Pfizer bivalent COVID-19 vaccine. However, it has been twisted to falsely claim that the CDC and FDA are warning people about the risk of stroke from the COVID-19 vaccine.

Fact #1 : CDC + FDA Notification Is Available Online

On Friday, January 13, 2023, the CDC and FDA published a notification on a “preliminary safety signal” involving the new Pfizer COVID-19 bivalent vaccine, which is available online.

I strongly encourage you to read it for yourself, but for your easier understanding, here is a quick summary:

Fact #2 : Multiple Analyses + Studies Fail To Validate This Signal

While the CDC and FDA will continue to evaluate the data, they pointed out that multiple analyses and studies failed to validate this safety signal.

Again, the VSD surveillance system was the only one producing this safety signal. No other surveillance system or study has been able to confirm or validate this safety signal.

In fact, the CDC made a point in their notification to say that “it is very unlikely that the signal in VSD represents a true clinical risk“.

Fact #3 : Safety Signals Are Not Evidence Of Causation

Safety signals function like tripwires, alerting health authorities into taking a close look at potential issues with vaccines or medicines.

Just because a safety signal was detected, it does not mean there is an actual problem. Like actual tripwires can be accidentally triggered by animals or falling branches, safety signals may be the result of random chance or other factors (see next fact).

The detection of any safety signal merely means that the CDC and FDA should take a closer look.

Fact #4 : Elderly Population At Higher Risk Of Stroke

I should point out that the safety signal was identified only in elderly people who were 65 years and older.

The VSD system, in this case, found that 130 people who were 65 years and older had a stroke within 21 days of receiving the new bivalent vaccine, out of about 550,000 senior citizens. It should be noted that no deaths were reported.

That may sound alarming, but this population segment is itself at significantly higher risk of developing blood clots, which can cause ischaemic stroke:

High Risk

Moderate Risk

That is why such safety signals have to be investigated, as it is still not certain if the 130 senior citizens who suffered a stroke had higher risk factors like surgery or immobility.

Fact #5 : CDC Still Recommends Getting Bivalent Vaccines

The CDC issued that notification as a matter of transparency, and not because there was a genuine reason for concern.

If the CDC and FDA had any reason to believe that the Pfizer bivalent COVID-19 vaccine can cause stroke in senior citizens who receive it, they would have at least amended their vaccine recommendations.

Yet, the CDC continues to recommend that people who are eligible to receive the updated bivalent COVID-19 vaccine should continue to get them.

The CDC also stressed that multiple studies have shown that “staying up-to-date with vaccines is the most effective tool we have for reducing death, hospitalisation, and severe disease from COVID-19“.
