Part of the public health message has been focused on making sure that people come forward, even before this was detected in the sewage works. One thing we saw as a result of lockdown was that some parents in some areas had not taken their young children to their doctor to have the vaccine. Let me be clear: at eight, 12 and 16 weeks, a child gets a 6-in-1 vaccine; at three years and four months, as part of the 4-in-1 preschool booster, they get it; and at 14 years they get one at school as a teenage booster. Some of those are pre school. We are encouraging people to check their red book, check their vaccination record and make sure they take their child in for their vaccine.
