A lot of people sneered at the extensive precautions and immunizations a few years ago, because nothing happened. "It's all hype and hoax and BS, doctors and scientists are idiots, why did we spend all this money, we could have bought a lot of cheap beer with that dough."
IF (and that is a big if) the people that decide what strains to protect against select the right strains, and enough people get vaccinated, there won't be an epidemic to worry about so people will think it was no big deal.
OTOH, they have been wrong so often with their predictions that no one believes them any more. It is a lot like the weather forecasters. They are so often off base most people just no longer worry about weather warnings.
