The risk of the public getting diphtheria is "very low" despite an expected rise in the number of infections being recorded among asylum seekers, according to the Health Secretary.
Steve Barclay said hundreds of migrants were vaccinated against the highly contagious disease before being moved out of the centre and into hotels around the country.
In the UK uptake for the diphtheria vaccinations is high as it is included in the 6-in-1 doses given to babies at eight, 12 and 16 weeks of age, and then again at 3 years and four months in the 4-in-1 pre-school booster.
