The WHO predicted that 150 million people would be killed by avian flu [1]. Nothing happened. They predicted 750,000 people would die in the UK, it was more like 200. For swine flu it was minimum possible deaths of 11k but up to 70k. It was more like 400. They got upset when people wouldn't use their case fatality rates which turned out very wrong. Over half a million people died of flu related deaths last year. Don't recall reading a single news article about it
