TeacherAnne and HannahLoisLuke:
Was going to make the same point about having the flu vaccine a bit later on in the season, otherwise protection wanes by February/March. As my DH and I would be due our Covid boosters in November, will have no qualms about having both the same day if still being offered in that way; by then, if it is causing problems to have them at the same time, it will have come out in the wash! The only thing is, they tend to run out of flu vaccine part way through the season, always assuming they have picked the correct strain of flu this year in the first place, they don't always predict it correctly
