MMRV is now part of the NHS routine childhood vaccination programme, replacing the MMR vaccine.
It protects against measles, mumps, rubella and chickenpox.
Chickenpox is very common and can sometimes lead to serious complications, so vaccination helps reduce the risk of serious illness as children grow.
You don’t need to do anything — your GP surgery will be in touch when your child is due.
