How safe are vaccines? Health officials caution that no vaccine is 100% safe, but they sponsor studies that conclude the benefits of vaccines far outweigh the risks. Yet conflicts of interest (COls) cloud the study of adverse effects of
vaccines, and public skepticism about vaccine safety information is widespread(ASTHO, 2010). Investigation into the possible link between childhood vaccines and autism provides an illustration of the competing interests that sponsors of vaccine safety research face that could affect their objectivity in choosing
which studies to support. Much research is sponsored by vaccine manufacturers
and public health bodies, who have financial and bureaucratic interests that could impede the objective study of vaccine safety.
