Study finds no link between vaccines and serious adverse effects

A recent study conducted by the Agency for Healthcare Research & Quality (AHRQ) found that serious adverse events resulting from widely used vaccines in the U.S. are rare.

The results of the study, published in the July issue of Pediatrics, also addressed several common concerns about routine vaccinations.

"Vaccines are some of the safest medical products available, and our recommendations and use of them is based on an assessment of the benefits and the risks," National Vaccine Program Office Director Bruce Gellin said. "This independent report reaffirmed that while serious adverse events can occur, they are rare."

The report found scientific evidence that there is not a link between the measles, mumps, rubella vaccine (MMR) and autism. The MMR, diphtheria, tetanus, pertussis, influenza and hepatitis B vaccines were found to not lead to childhood leukemia.

The AHRQ study also found moderately strong scientific evidence that no link exists between human papillomavirus vaccines and appendicitis, stroke, seizures, venous thromboembolism, onset of juvenile arthritis or onset of type 1 diabetes. No link was found between inactivated influenza vaccines and adverse outcomes for women who are vaccinated while pregnant.

"The use of vaccines ranks among the most significant public health achievements," AHRQ Director Richard Kronick said. "This review of the evidence provides important reassurances about the safety of commonly used vaccines."

The AHRQ report examined results from a 2011 Institute of Medicine study, along with findings from 166 other studies.
