White House Messaging on COVID Vaccine Stroke Risk Under Scrutiny
Newly released documents reveal White House officials edited messaging surrounding a safety signal indicating a higher-than-expected number of strokes following COVID-19 vaccination. The alterations, made in January 2023, involved downplaying the risk of ischemic stroke – stroke caused by blood clotting – from “moderately elevated” to “slightly elevated,” and removing the phrase “potential risk” altogether.
Downplaying the Data: What the Records Show
Emails show health officials expressed concerns about the changes. One official acknowledged some edits were “helpful,” but others were deemed “overkill.” The CDC announced the initial safety signal on January 2023, identifying an increased risk of ischemic stroke in individuals aged 65 and older after receiving the Pfizer-BioNTech bivalent COVID-19 vaccine. The announcement followed internal discussions and revisions to the initial findings.
Previous Safety Signals and the Bivalent Vaccines
This isn’t an isolated incident. Documents previously released indicated the CDC identified hundreds of safety signals for the original COVID-19 vaccines in 2022 through the Vaccine Adverse Event Reporting System (VAERS). The signal associated with the bivalent vaccines was first identified in November 2022. A CDC official, in a December 2022 email, highlighted the White House and Department of Health and Human Services’ (HHS) “intense push to increase uptake of the booster in that age group” as context for the situation.
The Evolving Understanding of Stroke Risk
Initial investigations focused on the Vaccine Safety Datalink (VSD), which compared stroke rates in elderly individuals within 21 days of vaccination to those vaccinated 22-42 days prior. Although the signal wasn’t consistently found in other monitoring systems, and other countries didn’t report similar findings, the CDC and FDA acknowledged the signal and shared the information publicly, stating it was “very unlikely” to represent a true clinical risk.
The Role of Concurrent Flu Vaccination
Further analysis suggested the signal was primarily linked to individuals who received a Pfizer COVID-19 shot and an influenza vaccine on the same day. Data showed 40 stroke cases within 21 days among those receiving both vaccines simultaneously, compared to 20 cases in the 22-42 day window. For those receiving only the Pfizer vaccine, the numbers were 60 and 58, respectively.
A March 2024 FDA study confirmed an elevated risk of non-hemorrhagic stroke in elderly people following vaccination with Pfizer and Moderna COVID-19 vaccines, but again, this risk was primarily observed in those who received an influenza vaccine concurrently. Researchers concluded the risk was “likely driven by a high-dose or adjuvanted influenza vaccination.”
Continued Recommendations and Current Debate
Despite the emerging data, the government continued to recommend COVID-19 vaccination for nearly all individuals aged 6 months and older, including those previously vaccinated, and advised simultaneous administration of influenza vaccines. Senator Ron Johnson, chairman of the Permanent Subcommittee on Investigations, has criticized the administration’s handling of the situation, alleging a willingness to downplay safety risks.
Looking Ahead: Calls for Transparency
Johnson has requested additional records from Health Secretary Robert F. Kennedy Jr., including documentation related to a “Stroke Project” conducted by a CDC contractor. He also seeks interviews with key CDC officials involved in vaccine safety assessments. The senator argues that health officials continued to assert vaccine safety while simultaneously seeking evidence to support that claim.
FAQ
Q: What is a safety signal?
A: A safety signal is an indication that a vaccine may be associated with a particular health issue, requiring further investigation.
Q: What is ischemic stroke?
A: Ischemic stroke is a type of stroke caused by a blockage of blood flow to the brain.
Q: Did the CDC change its recommendations regarding COVID-19 vaccines?
A: No, the CDC continued to recommend COVID-19 vaccination for most individuals despite the identified safety signal.
Q: What role did the flu vaccine play in the stroke risk?
A: Data suggests the risk of stroke was elevated when the COVID-19 vaccine was administered concurrently with an influenza vaccine.
Did you know? The VAERS system is a passive reporting system, meaning reports are submitted voluntarily and don’t necessarily indicate a causal relationship between the vaccine and the adverse event.
Pro Tip: Discuss any concerns about vaccine safety with your healthcare provider to make informed decisions about your health.
