The council are appealing for people to check whether they have received the full course of MMR vaccinations.
In the first quarter of this year there have been five confirmed cases of measles and two of mumps.
Figures from 2016/17 indicate 82 per cent, rough one in five, five-year-olds have received two doses of the MMR vaccination.
The World Health Organisation’s recommended level of immunisation is 95 per cent.
Matthew Cole, director of public health at Barking and Dagenham Council, said: “It is important parents get their children vaccinated but it isn’t just about youngsters - these diseases do not discriminate on age and it is vital adults are protected too.
“If you aren’t immunised or if you can’t remember if you have had the MMR jab, please book an appointment with your GP as soon as possible.”
