43,000 children and teenagers are to be targeted in an urgent vaccination drive in Wales to halt the spread of the measles epidemic in the Swansea area.
The total number of measles cases in Wales has reached 1,170 cases and a further 28 cases have been reported since Tuesday.
Public Health Wales said that over 33,000 non-routine vaccinations had been given in Wales, but less than 25% had been to the at-risk group of 10 to 18-year-olds. This leaves 43,000 in Wales in the key age group needing vaccination.
