Heart attack

82-yr old friend in hospital 22 September,  for symptoms of heart attack. Doctors cannot find any cause for concern with his heart after tests. I asked him if he had had a jab. He was surprised at my question. Yes, he’d had the first one. Nobody told him about any possible reactions. Fortunately he’s recovering. What do I tell him if he thinks of getting a second jab?
