One million children will be targeted in a measles vaccination drive across England as an outbreak in Wales continues to grow.
ITV News Science and Medical Editor Lawrence McGinty reports:
Public Health Wales is urging young people to get the MMR vaccination before the start of their exams.
56 new cases have been reported in the measles outbreak since Tuesday, bringing the total number to 942.
Public Health Wales says 83 people have now been hospitalised since the outbreak started.
One million children who missed out on the MMR vaccine in England are being targeted in a campaign to raise the level of protection against measles.
Young people who have not had either one or two doses of the MMR jab will be offered the vacine in a campaign costing £20 million at GP surgeries and schools.
Secondary schools in Swansea and Neath Port Talbot will be targeted in another round of school MMR vaccinations this week.
Over 1,700 pupils will be offered the jab in 10 schools across the areas.
Health experts have urged parents of pupils who have had no MMR or who need a second jab to take advantage of the school clinics.
Around 3,400 people turned out to receive the MMR vaccination in the latest round of clinics in South Wales over the weekend.
Health chiefs at Abertawe Bro Morgannwg University Health Board say 1,800 people were vaccinated at the area's four drop-in MMR clinics today – the highest number so far.
The full numbers are:
- Princess of Wales Hospital: 727
- Neath Port Talbot Hospital: 455
- Morriston Hospital: 341
- Singleton Hospital: 302
Many of the 1,825 given MMR jabs were older schoolchildren, teenagers and young adults - the target age group for vaccines.
Dr Marion Lyons of Public Health Wales says with 20 new cases of measles daily in Wales at the moment a death would not be surprising.
An investigation is underway on Friday to find out if a 25 year-old man from Port Tennant near Swansea died from the virus.
It is reported that a 25 year old man found dead at a flat on Port Tennant Road in Swansea yesterday died from 'suspected' measles.
South Wales Police have confirmed that the death is not being treated as suspicious and that officers are awaiting the results of a post mortem examination.
Public Health Wales have told ITV News that they will be releasing a statement 'shortly.'
Public Health Wales says vaccinations are being offered to parents in Swansea "on a scale never seen before."
It says the measles virus has continued to circulate and spread among children in the easter holidays, and is expected to spread further among those susceptible now they are back at school.
Public Health Wales says there are now cases of measles in every health board area in Wales.
Dr Marion Lyons, Director of Health Protection, says "we have no way of knowing where the outbreak might spread."
