The latest measles figures are due out this afternoon following the cessation of MMR clinics and school vaccination sessions.
Figures released by Public Health Wales on Thursday revealed there have been 1,336 confirmed cases of the virus across Wales since November.
The last of the drop-in clinics were held over the weekend and school vaccination sessions ended on Friday, but the MMR vaccine remains available through GP surgeries. Over 60,000 people in Wales have now received the jab.
