Conclusion and Relevance Among adults with mild COVID-19, a 5-day course of ivermectin, compared with placebo, did not significantly improve the time to resolution of symptoms. The findings do not support the use of ivermectin for treatment of mild COVID-19, although larger trials may be needed to understand the effects of ivermectin on other clinically relevant outcomes.
If one wants to avoid severe Covid infections, and long term effects from the virus, then the preventative is to get vaccinated with a mRNS vaccine. So simple.
