Regarding ivermectin for prophylaxis, they cite four randomized controlled trials and three observational studies. Two of the RCTs were done in Egypt, one in Argentina, and one in Bangladesh, ranging in size from 100 to 300 patients. Marik and colleagues also cite "natural experiments" in Peru, Brazil, and Paraguay where ivermectin was distributed widely, with "large decreases in case counts ... soon after distribution began."

Same here - did my initial 2 doses over the weekend and have the 4 week periods on my calendar for “boosters”.
