From Wikipedia:
Heying has said that she has taken ivermectin to guard against COVID-19 and that she and Weinstein have not been vaccinated "because we have fears [about the side-effects of the COVID-19 vaccines], as we have discussed at length on this podcast." Heying compared the use of ivermectin for this purpose to taking anti-malarial drugs.[4] Whereas all WHO-approved vaccines have shown a high level of safety and efficacy in all populations,[27] there is no good evidence of benefit from ivermectin in preventing or treating COVID-19.[28][29]
