Health and Human Services Secretary Robert F. Kennedy Jr.'s decision to terminate $500 million in federal funding for mRNA vaccine development threatens to unravel one of medicine's greatest recent achievements. His claim that these vaccines "fail to protect effectively against upper respiratory infections like Covid and flu" represents a fundamental misunderstanding of vaccinology that could cost lives in future pandemics. No vaccine for respiratory viruses has ever provided complete, lasting protection against all infections. Not the flu vaccine. Not RSV vaccines. That never should have been the expectation. Some vaccines, like those for measles or polio, can effectively prevent infection and transmission, but these target fundamentally different viruses that don't constantly mutate and reinfect the respiratory tract. The purpose of respiratory virus vaccines is to prevent severe disease, hospitalization and death. By that measure, mRNA vaccines have been revolutionary. RFK Jr. is dangerous! Stop enabling him.
