About

It is administered in two doses, typically in childhood, and is considered highly effective in preventing these diseases. The vaccine works by introducing a weakened or inactive form of the pathogens into the body, allowing the immune system to recognize and mount a defense against them. The MMR vaccine has been in use since the 1970s and has significantly reduced the incidence of these diseases. However, controversy and concerns about the vaccine's safety have also arisen, particularly in relation to the discredited claim that it can cause autism. These concerns have been addressed by numerous studies that have found no evidence linking the MMR vaccine to autism or other serious adverse effects. Despite these reassurances, vaccine hesitancy and refusal remain a challenge, contributing to outbreaks of preventable diseases. The page provides a comprehensive overview of the MMR vaccine, including its composition, administration, effectiveness, safety, and the history of its development and controversies.
