Browsing: MMR Vaccine

The MMR vaccine is a combination vaccine that provides immunity against three highly contagious viral diseases: measles, mumps, and rubella. Introduced in the 1970s, the vaccine contains live, attenuated (weakened) viruses of these three diseases and is typically administered in two doses, with the first dose given in infancy and a booster dose during early childhood. The MMR vaccine is highly effective, with more than 95% efficacy in preventing these diseases. Measles, mumps, and rubella can lead to severe health complications, including pneumonia, encephalitis, deafness, and birth defects if contracted during pregnancy. The vaccine has been crucial in reducing the prevalence of these diseases worldwide and is considered safe, with side effects typically mild. Despite misinformation about its association with autism, extensive scientific research has shown no link between the MMR vaccine and developmental disorders.
