Finland's measles scare with virologist Mia Kontio

A pre-schooler diagnosed with measles in late November prompted health officials in western Finland cast their net wide to track down everyone the child may have come into contact with -- and since then officials have diagnosed more measles cases. The latest round of infections has prompted a national debate on how to maintain herd immunity so that vulnerable groups of people who cannot be vaccinated do not risk infection. All Points North talks with Mia Kontio, a senior measles and MMR specialist with the national public health watchdog THL, about the occurrence of measles in a country, where many people have been vaccinated, but where there are some gaps in vaccination coverage. 14 December 2018 / All Points North / Yle News
