8th treatment shown to reduce risk in October 2020
 
*, now with p < 0.00000000001 from 122 studies, recognized in 9 countries.
No treatment is 100% effective. Protocols combine treatments. * >10% efficacy, ≥3 studies.
4,500+ studies for 81 treatments. c19early.org
RCT 321 healthcare workers in Mexico, showing significantly lower SARS-CoV-2 infection with vitamin D prophylaxis. 4,000IU daily for 30 days.
In comparison to Jolliffe et al., this study used a higher dose, the participants had much higher exposure to SARS-CoV-2 patients, and the study was prior to vaccination. In Jolliffe et al., 89% of participants had received a vaccine dose by the end of the study period, and the period overlapped with increasing solar UVB.

This is the 13th of 30 COVID-19 RCTs for vitamin D, which collectively show efficacy with p=0.0000032.
This is the 76th of 122 COVID-19 controlled studies for vitamin D, which collectively show efficacy with p<0.0000000001 (1 in 587 sextillion).
risk of hospitalization, 66.5% lower, RR 0.33, p = 1.00, treatment 0 of 150 (0.0%), control 1 of 152 (0.7%), NNT 152, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm), ITT.
risk of case, 78.0% lower, RR 0.22, p = 0.001, treatment 7 of 150 (4.7%), control 26 of 152 (17.1%), NNT 8.0, adjusted per study, multivariable, Table 3.
