I don’t think the flu vaccine ever had a particularly high turnout, though. It’s less to do with vaccine scepticism and more to do with the fact that it’s optional and requires most people to go out of their way to get done. Couple that with the fact that seemingly every year there is a media campaign to scare people into getting it, and I think a lot of people just switch off. The only group that consistently takes it in high numbers are over-65s.
