Most colds are not caused by coronaviruses (only about one cold in seven) so you wouldn't know whether that was a useful strategy anyway as you wouldn't know which virus you had.

I had my flu jab a couple of days ago and I'm getting boosted on Monday. As I had covid in July I'm hoping that lot will see me through relatively unscathed (giving it my best shot if you'll excuse the pun).

I have the mother and father of a cold at the moment (not covid - tested negative twice this week), so, who knows, I might be one of the one-in-seven. Masks are rarely seen round here and no-one insists that you wear one. I hear that infection numbers are on the up again. The government here, presiding over a health service that they've rendered unfit for purpose, is getting worried about a possible double whammy of flu and covid this winter.
