MMR vaccine controversy

The MMR vaccine controversy revolves around claims that the vaccine, which protects against measles, mumps, and rubella, might cause autism. In 1998, a study suggested a link, but it was later discredited due to serious scientific flaws and ethical issues. Extensive research since then shows no evidence of a connection between the vaccine and autism. Despite the lack of evidence, the controversy led some parents to delay or avoid vaccination, increasing the risk of outbreaks. Health organizations worldwide recommend the MMR vaccine as safe and essential for public health.
