Let's check out the main author:

"Brazil’s main champion of ivermectin, Lucy Kerr, an ultrasound expert who talks about the supposed danger of mammograms to women, claims to have cured at least 20 patients in two days after reading the Australian study’s findings. The mayor of Itajaí has called her a “pioneer in the fight for ivermectin.” She often points to personal observations and testimonies shared by colleagues on WhatsApp groups as proof of the drug’s benefits. Her videos endorsing the drug, one of which was recently taken down by YouTube for spreading misinformation, reach hundreds of thousands of people."
