The first dose is usually given to babies at a year old, the second dose before they go to school. So-called "no jab, no school" policies have been introduced in several nations around the world and have shown promising results in increasing the number of vaccinated children.
Prof Heidi Larson, director of the Vaccine Confidence Project at the London School of Hygiene & Tropical Medicine, said: "With more than 5% of five-year-olds in England not having had their MMR vaccination when they start school, and the United Kingdom losing its "measles-free" status three years after being certified for measles elimination by the World Health Organization, it is time for more urgent action".
The numbers of children having the four-in-one booster against diphtheria, whooping cough, tetanus and polio has also fallen. Earlier this year a Unicef report warned that half a million British children were not immunised against measles between 2010 and 2017.
The drive is announced just months after it was also reported that European cases of measles have hit a ten-year high, with 32 cases confirmed across Greater Manchester, causing concern across the UK. If not, parents should contact their GP practice to arrange any further vaccinations that are needed.
The Prime Minister said: 'From reassuring parents about the safety of vaccines, to making sure people are attending follow-up appointments, we can and must do more to halt the spread of infectious, treatable diseases in modern-day Britain'.
In total, this leaves around 90,000 children unprotected as they prepare to start school.
"Frontline medical staff must be given the resources to provide a successful and comprehensive vaccination programme - to protect children in all parts of the population". Around 7,000 of these children are in the East Midlands.

Around 100,000 (one in eight) five-year-olds in England may still need their four-in-one pre-school booster which protects against diphtheria, whooping cough, tetanus and polio.
Britain was declared "measles free" by the World Health Organisation in 2016 after a 36-month period with no "endemic" transmission - meaning the only outbreaks in that time had started overseas and were then passed on.
To check that your child has received all their vaccines on schedule, visit the NHS website and refer to your child's Red Book.
And, PHE continues to call for those who missed out on their MMR vaccination at the scheduled time to make an appointment now.
As part of the drive he will visit a hospital in the South West and lay out a number of measures created to improve vaccination rates, including for measles, mumps and rubella (MMR).
It's easy to forget how devastating measles can be precisely because vaccines are so effective at preventing it in the first place. PHE's catch-up call for primary school starters follows the issue of a new GP contract from NHS England and Improvement which also encourages 10 and 11-year olds to be caught up with any missing MMR vaccinations prior to them reaching secondary school age.
With this strategy, the whole health system will come together to renew focus on vaccinations - especially for our children - and this time we will eliminate measles for good."Many people don't know that CDC recommends completing a series of two MMR immunizations before traveling to many countries", explained Crockett Tidwell RPh, CDE, Clinical Services Manager, Vaccine Specialist with United Supermarkets Pharmacy.
