RFK Jr. incorrectly claims that MMR vaccine immunity wanes significantly each year (4.5%), rendering older individuals essentially unvaccinated. Scientific studies, such as one in 'The Lancet,' show a much lower annual waning rate of 0.04%. This statistical exaggeration creates a false narrative about vaccine ineffectiveness, ignoring the long-term protection provided by vaccines and the minimal need for boosters in most cases.
Impact: Medium. Debunks another claim about vaccine ineffectiveness by correcting the statistical data, showing RFK Jr.'s pattern of misrepresenting scientific findings.
