Pushing through a crowded hospital corridor behind my father, I heard a voice calling me.

Then a nurse grabbed me and threw her arms around me. She had heard my father’s name and recognised me, her old school friend from St Joseph’s.

As we walked and talked, she told me, ‘We all read your articles’ and I thought: ‘Oh dear I’m about to be exposed as an anti-vaxxer in the middle of A&E while my father’s having a heart attack.’
