The SAIVE Trial, Post-Exposure use of ivermectin in Covid-19 prevention: Efficacy and Safety Results
Desort-Henin et al., ECCMID 2023 (results released 1/5/2023), SAIVE,
NCT05305560
PEP RCT 399 patients in Bulgaria showing significantly lower COVID-19 cases with ivermectin prophylaxis, and significantly lower cases with high viral load. No participant had severe symptoms, required oxygen, or was hospitalized. All patients with COVID-19 were treated with vitamin C and vitamin D.
This trial makes the Cochrane analysis report statistically significant efficacy for prophylaxis, although they do not appear to have acknowledged this yet. There are currently 4 prophylaxis RCTs, and all 4 show statistically significant efficacy of ivermectin. Cochrane ignored them by simply choosing to only include post-exposure prophylaxis RCTs, even though they were included for the paxlovid analysis with many of the same authors. At the time there were no post-exposure RCTs and they knew that including any one of the 3 pre-exposure prophylaxis RCTs would show statistically significant efficacy.
