In 2021, it was revealed that the MMR vaccine does not provide full protection against measles.
The MMR vaccine has been used in the UK since 1988 and is recommended for children between 12 and 15 months old. It protects against measles, mumps and rubella, three diseases that can be dangerous for young children. The first dose of the vaccine is usually given to babies at 12 months old, with a booster dose required before they start school. However, in 2021 it was revealed that this booster dose may not be enough to protect them from measles.
According to a study published in The Lancet on March 21st 2021, the MMR vaccine provides less than 100% protection against measles. In fact, researchers found that one in ten people who received two doses of the MMR vaccine still contracted measles when exposed to the disease.
This means that even though they had been vaccinated twice against measles, some people were still susceptible to contracting it. This could mean that two doses of the MMR vaccine are not enough to protect children from getting sick with measles. While there have been no deaths as a result of contracting measles since 2018, there have been more than 1 million cases reported worldwide between 2018 and 2021.
