WHO Director General dr. Tedros about the serious challenge posed by anti-vaxxers

"But you know the serious challenge that's posed by anti-vaxxers. And I think we need to strategize to really push back because vaccines work...And we have science evidence on our side. I think it's time to be more aggressive in pushing back on anti-vaxxers. I think they use COVID as an opportunity and all the havoc they're creating. Maybe that's one of the messages also I'd like to include to whatever I have said."
