No. Yes. Only if you have pre-existing health issues.
Stupid system really. There's heaps of people not getting them, but my Mum wanted to do the right thing and get a booster shot when the new vaccine (that's better targeted to the current strains) came out as it had been more than 6 months since she'd had a shot. The pharmacy told her she'd have to wait until it had been 12 months. With the rate of transmission and virus mutation every 12 months is a long stretch on vaccines that are always lagging a long way behind the current strains (and thus are only moderately effective - but still worth getting for preventing severe disease and excessive transmission to others...).
We got our boosters a month before we went to Europe - I'd rather have some protection against new variants.
