4. VACCINE DEBATE The US Food and Drug Administration (FDA) regulates all vaccines to ensure safety and effectiveness. No federal laws mandating vaccination exist, but all 50 states require certain vaccinations (exemptions allowed) for children entering public schools. Proponents argue that vaccination is safe and one of the greatest health developments of the 20th century. They point out that illnesses, including rubella, diphtheria, and whooping cough, which once killed thousands of infants annually are now prevented by vaccination. They contend that anti-vaccination studies are often faulty, biased, and misleading. Opponents argue that children’s immune systems can deal with most infections naturally, and that the possible side effects of vaccination, including seizures, paralysis, and death, are not worth the risk of safeguarding against non-life threatening illnesses. They contend that numerous studies prove that vaccines may trigger problems like autism, ADHD, and multiple sclerosis.
