Drew Weissman refutes RFK Jr. adviser’s claims about Covid shots

The Centers for Disease Control and Prevention recently convened a meeting of its Advisory Committee on Immunization Practices to discuss the recommendation of Covid-19 vaccines to the public. The panel decided to postpone a controversial vote and made recommendations aimed at addressing doubts about the vaccines while ensuring their widespread availability.

During the meeting, concerns were raised about the safety of mRNA Covid vaccines, particularly those produced by Moderna and Pfizer/BioNTech. Retsef Levi, who chairs ACIP’s working group on Covid vaccines, expressed worry about the potential persistence of mRNA, lipid nanoparticles, and spike proteins in the body. He also mentioned possible immune responses that are not fully understood and could impact genetic material. However, Moderna and Pfizer countered these claims by citing well-conducted studies that met global regulatory standards.

In response to these concerns, Drew Weissman, a professor at the University of Pennsylvania and co-recipient of the 2023 Nobel Prize in Physiology and Medicine for his work on mRNA vaccines, addressed the issue. He emphasized that while some studies may suggest widespread distribution of mRNA in the body, the majority of research refutes these claims. Additionally, he dismissed the idea of mRNA persisting in the body for extended periods.

Weissman also tackled the issue of spike protein production, highlighting that some studies using sensitive assays may have reported false positives. He emphasized that mRNA vaccines have been extensively studied and proven to be safe and effective, with no evidence of long-term mRNA presence or unintended protein production.

Furthermore, concerns about DNA contamination in vaccines were addressed, with Weissman explaining that minute amounts of DNA are common in vaccines and have not been linked to adverse effects. He stressed the importance of vaccines in saving lives and preventing diseases, citing the significant impact they have had on global health.

In conclusion, Weissman reiterated the safety and efficacy of mRNA vaccines, emphasizing their role in saving lives and controlling the Covid-19 pandemic. He urged the public to trust in the extensive testing and research that has gone into developing these vaccines, highlighting their importance in public health efforts.
