What about over 60s who constitute a lage part of the readership. Are we too frail?
Incidentally I went to my annual elephant party yesterday, really, and one of my hosts, Australian, aged 60 hadn't bothered with the shingles vaccine. Luckily I have. Facially he was quite disfigured, and only has partial sight in one eye. I didn't know it could strike like that. I'm a firm believer in taking every vaccine going, whatever the Republicans may say. Just read a survey saying measles, whooping cough, polio, dangerous illnesses, are up sharply in the US, particularly in Republican States.
