The development of mRNA vaccines, including initiatives like Operation Warp Speed, was pivotal in the U.S. pandemic response, underscoring their public health importance.

The Department of Health and Human Services recently canceled nearly $500 million in mRNA vaccine research funding, citing data that supports their safety and effectiveness against COVID-19 and flu.

Full Fact concludes that Robert F. Kennedy Jr.'s claims about mRNA vaccines lack scientific support, highlighting that these vaccines are effective and safe, with expert consensus affirming their role in reducing COVID-19 severity and mortality.

Kennedy's use of discredited sources and biased figures with conflicts of interest undermines his anti-vaccine stance, according to Full Fact.

Kennedy announced that the US Department of Health and Human Services would cease funding mRNA vaccine research, falsely claiming these vaccines fail to protect effectively and promote viral mutations, which Full Fact finds misleading.

mRNA vaccine technology, which delivers instructions for viral protein production, is faster to develop and has been proven highly effective through multiple studies, including a 2022 Lancet study and a 2024 WHO report.

Historical data shows COVID-19 vaccines have saved over 20 million lives in their first year alone, with effectiveness estimates exceeding 90%, demonstrating their critical role in pandemic response.

Experts clarify that viruses naturally develop resistance through mutation driven by natural selection, a process common to all vaccines and infections, not specific to mRNA vaccines.

Extensive studies and endorsements from the CDC and FDA confirm that mRNA vaccines, such as Pfizer-BioNTech and Moderna, are safe and have saved millions during the pandemic.

While no mRNA flu vaccines have yet been approved, early trial results suggest they are more effective than standard flu vaccines, contradicting Kennedy's assertions.

Kennedy falsely claims that mRNA vaccines cause new mutations in respiratory viruses; experts explain that mutations occur randomly and are not caused by vaccines.

A review of scientific publications by the US Department of Health and Human Services shows they do not support Kennedy's claims regarding vaccine efficacy or virus mutation.

Kennedy's claim that mRNA vaccines perform poorly against upper respiratory viruses is false; studies show vaccinated individuals experience better outcomes and vaccines have prevented millions of deaths globally.
