As an expat in the US for many years (healthy adult with no underlying conditions), I never got the flu jab on a regular basis until last year after Covid started. (Of course I got the Covid jabs and other one-time standard jabs like hepatitis etc.)The American GP I see for my annual physical exam always told me to get the flu jab but I refused. It never made sense why back home I would only have to get the jab during pregnancy and then annually after age 65+, whereas in the US everyone including children, regardless of age, is told to get the jab annually.
Other expats in the US -- did you and your DC get the flu jab annually pre-Covid? Besides financial reasons (e.g. US can afford jabs for everyone annually but the NHS is poor so only offers it to at-risk groups, US has fewer holidays so workers can't afford to be ill with flu), is there any scientific basis for why healthy people should NOT get the flu jab each year? If the NHS offered free flu jabs to all ages annually like the US, would you and your DC get it in the UK during normal non-Covid times?
