Chicago - A US high school student who had himself vaccinated despite his parents' objections is set to testify Tuesday before the US Congress about a surge in outbreaks of preventable diseases.
Lindenberger, who lives in Norwalk, Ohio, announced over the weekend that he was invited to testify at a Tuesday hearing in the US Senate over preventable disease outbreaks. Parents in 17 states are allowed to opt out of vaccinations for their children because of their personal beliefs. Medical and religious reasons also can be cited to forego vaccinations.
