Protecting Wales from illness and threats to public health

We are working to prevent illness and protect from threats to public health. These could include:

  • infections
  • communicable diseases and
  • environmental hazards.

We are also responsible for running national vaccination and immunisation programmes.

In this section you can find out about government policy on immunisation and communicable diseases, as well as plans, advice and guidance in case of public health emergencies.

You can get more information on health protection and prevention from:
