The FDA panel’s COVID vaccine approval ignited safety concerns on May 22, 2025, after recommending the 2025-2026 formula for COVID-19 shots.
Specifically, the Vaccines and Related Biological Products Advisory Committee’s decision sparked immediate backlash from experts.
Consequently, critics on X and beyond questioned the safety of these vaccines, citing emerging research on their harms. Thus, the FDA vaccine safety concerns debate underscores a growing distrust in public health decisions.
Hulscher Exposes Vaccine Harms on X
Nicholas Hulscher, an epidemiologist, raised alarms about the FDA-approved vaccines on X on May 25, 2025. He stated,
“We found Spike and somebody 2.5 years after mRNA vaccination. We have some excess mortality papers coming out. We identified large increases in deaths after vaccination. So a lot of the pipeline at the McCullough Foundation here, we’re now over our 20th study looking at the harms of these shots.”
Moreover, Hulscher emphasized,
“There are millions of vaccine injured Americans. And so we have to start helping these people out. I don’t know how many people, if you go ask any of your friends or family, usually somebody knows somebody that has either died or been permanently disabled.”
Therefore, the FDA vaccine safety concerns intensified with Hulscher’s findings. Learn about vaccine injuries.
We found vaccine spike protein 2.5 YEARS after mRNA injection — and uncovered major spikes in excess mortality. New studies coming soon.
As the government turns its back on mRNA harms and the vaccine-injured, the McCullough Foundation is picking up the pieces. https://t.co/OYYExk52jP pic.twitter.com/LP6EQAIDbC

McCullough Warns of Spike Protein Dangers
Dr. Peter McCullough further escalated the safety concerns with his warnings about the spike protein. On May 25, 2025, the McCullough Foundation posted on X, with McCullough stating,
“It’s probably the most detrimental protein we’ve ever seen for the human body. Now, the hope was—this was the gamble—that we’re going to have the body produce this horrible protein. And we’re going to produce enough antibodies to neutralize it. And the problem there is, quickly, the body got fatigued from seeing it all the time. So it went from the neutralizing IgG1, IgG2 antibodies, to the useless IgG4 antibodies, called IgG4 subclass switching. So people have this stuff in the bloodstream. The killer protein is in the bloodstream circulating, causing damage and blood clots making people feel bad.”
Indeed, McCullough’s research demands scrutiny of the FDA’s decision. Explore McCullough’s research.
The Spike Protein is One of the Most Dangerous Proteins in the World.

Calls for Accountability in Vaccine Safety
The FDA vaccine safety concerns have sparked urgent calls for accountability. For instance, Hulscher’s findings of excess mortality and McCullough’s warnings about the spike protein highlight potential risks ignored by the FDA panel.
Furthermore, X users echoed these concerns, pointing to a lack of government support for the vaccine-injured. Consequently, the debate raises a critical question: will the FDA address these safety issues?
Thus, transparency in vaccine approvals remains essential to rebuild public trust.
