evidence: FULL CLAIM: "There is not a single doctor in the world that can tell you that vaccines do not cause cancer. On every single FDA insert for every vaccine, there is a disclaimer of sorts which states that the vaccine has not been tested for carcinogenic or mutagenic effect [...] An explosion of childhood cancers (particularly leukemia) coincides with the explosion of vaccines after manufacturers were removed from liability [...] Big Pharma knows that among other things, vaccines can cause childhood cancers." In January 2024, political commentator and talk show host Candace Owens posted a tweet on X (formerly Twitter) claiming that vaccine package inserts state vaccines haven’t been tested for carcinogenic or mutagenic effect, that there has been an "explosion" of childhood cancers after manufacturers were removed from liability, and that "vaccines can cause childhood cancers". [...] To sum up, the reason why vaccine package inserts state that "the vaccine has not been tested for carcinogenic or mutagenic effect" is because there’s no scientific grounds to think the vaccine would cause either effect. Childhood vaccines don’t use novel adjuvants or additives and vaccine ingredients aren’t present in quantities that are expected to cause cancer, based on previous research.
