The MMRV vaccine protects against measles, mumps, rubella, and chickenpox. It contains weakened versions of these viruses. These weakened viruses help your child’s body build protection without causing the diseases.
A measles-type rash can occur after vaccination, but this has not been shown to spread to others.
Some children may get a chickenpox-like rash where the MMRV injection was given. Children can still go to school or childcare, but the rash should be covered with clothing.
Very rarely, a chickenpox-like rash may appear elsewhere on the body away from the injection site. If this occurs, it is more likely to be caused by natural chickenpox infection. Children with a rash of this type should be seen by their GP.
If you have any questions, speak to your practice nurse, GP or health visitor.
