What are the arguments against the vaccination of MMR?

Arguments against the MMR (measles, mumps, rubella) vaccine often stem from concerns about safety, with some claiming a potential link to autism, despite extensive studies disproving this connection. Critics may also fear side effects or adverse reactions, even though serious complications are rare. Additionally, some individuals believe in natural immunity through disease exposure rather than vaccination. However, these arguments are largely countered by public health data showing the vaccine's effectiveness and the risks posed by the diseases it prevents.
