Vaccines have caused an "explosion" of childhood cancer; vaccine package insert states vaccines weren’t tested for mutagenic effect
Childhood vaccines typically don’t undergo testing for carcinogenicity and mutagenicity because their safety has already been demonstrated in earlier studies. Published scientific studies so far haven’t found reliable evidence showing that childhood vaccination increases the risk of childhood cancer. In fact, some childhood vaccines, such as the Hepatitis B vaccine and the human papillomavirus vaccine, protect individuals from certain cancers.
