ABSTRACT
OBJECTIVES: To discuss information surrounding the erroneous association between the measles-mumps-rubella (MMR) vaccine and autism spectrum disorders (ASDs) and to provide pharmacists with information to dispel vaccine myths. DATA SOURCES: Pharmaceutical and medical literature and public media (e.g., newspapers). SUMMARY: The diagnosis of ASDs is on the rise, and many speculations have been made as to the cause, including the MMR vaccine. A small case series article published in The Lancet in 1998 and later retracted has been the center of the controversy over whether the MMR vaccine causes ASDs. New definitive research demonstrates no link, and medical organizations state that evidence does not support a link between the MMR vaccine and ASDs. CONCLUSION: Pharmacists can play a role in providing up-do-date information to patients to dispel myths concerning vaccine safety. Accurate peer review remains an important step to ensure correct information is given to health care providers and the public.
