To combat anti-vaccine #misinformation on #social media, @ShotsHeard was created. @ZDoggMD posted on #YouTube introducing the #DoctorsSpeakUp hashtag and asking healthcare professionals & pro-vaccine advocates to post on Mar. 5, 2020.

But the hashtag was co-opted. 2/7
So, who used the #DoctorsSpeakUp hashtag?
