I was talking to a patient the other day. She was a new mother and had been grappling with all the new mum health anxiety that springs from a media cycle dominated by measles, and a sleep cycle dominated by being awake too much.

She was recounting, with distress, a recent search she had undergone to find a GP clinic that would give her an MMR vaccination for free and angrily described how it was only the sixth practice she called that finally told her they would provide it without charge.

She had read in the news that it should be free for all, no matter age, or residency status, and that it should be sought out by people who were unsure of their vaccination history.

Driven by her concern for her baby, she had responded with action.
