People rejecting vaccinations could be one of the reasons behind why London is at reported risk of a major measles outbreak, an expert has said.

The UK Health Security Agency warned earlier in July that the capital could be on course for a wave of 40,000 and 160,0000 cases with dozens potentially dying.

After further consideration, Helen Bedford, a professor of children’s health at University College London, has said vaccine uptake needs to be higher to contain such diseases.
