"THE VACCINE DEBATE
Various groups have raised concerns about vaccinations, either questioning their efficacy or, more commonly, their safety. While there are rare occurrences of individuals experiencing severe side effects to a vaccine, these complications are less common than the adverse risks associated with the disease the vaccine prevents. Vaccines must undergo rigorous safety and efficacy testing before being introduced to the public. To date, any study questioning the safety of approved vaccines has been proven unreliable, and all studies investigating the efficacy and safety of these vaccines have found that they are safe and incredibly effective at preventing people from becoming ill with serious, deadly diseases.
Unfortunately, anti-vaccination sentiments have led to some people refusing to get vaccinated or having their children or relatives vaccinated. This has led to outbreaks of diseases that were previously controlled by herd immunity. For example, unfounded speculation about the safety of the mumps-measles-rubella (MMR) vaccine led to a decrease in vaccinations in Wales in the 2000s, leading to an outbreak of measles in 2013."
