Can children who have received the MMR develop rubella in 4-5 months later?
The direct answer to your question is yes but the risk is small. The MMR vaccine is a triple vaccine providing protection against measles, mumps and rubella, which is also known as German measles. A small number of children receiving the vaccine will develop a mild form of measles within 10 to 14 days of being vaccinated. This is known as mini-measles and despite itís occurrence the child is immune if it should be exposed to measles in the future. No vaccine can guarantee 100% protection against getting the infection for which the child has been immunised however the risk of developing the infection is very small. If a vaccinated child develops such an infection they tend to experience the illness in a milder form.
