In past years there has been ongoing concern that not enough people got the annual flu vaccine.Some of it was laziness, some of it was lack of education. There were few outright deniers that flu was a problem. Instead, it seemed to be the opposite. If someone had a bad cold they still said they had the flu, and some said they think they might have the flu, which led most doctors to remind people that if you think you have the flu, you don't have the flu. The real vaccine deniers were more coastal elites who believed a discredited former doctor, Andrew Wakefield, who was interested in selling a competitor to existing vaccines, and used a tiny sample of hand-picked kids to claim that vaccines caused autism in a paper that was then retracted.
