Media biases are a different issue. The WHO’s problem is that it’s supposed to be a politically neutral internationally governing body, and It’s conduct during the pandemic has lead many people to believe that it is operating according to a political agenda. The damage The WHO (and other public health institutions) have done to their trustworthiness has already had will continue to have serious consequences going forward. Anti-vaxx has never been so popular.
