Retrospective 294 consecutive patients in Japan, showing higher risk of hospitalization/death with molnupiravir, without statistical significance.
Concerns have been raised that the mutagenic mechanism of action may create dangerous variants or cause cancer Chamod, Hadj Hassine, Huntsman, Marikawa, Swanstrom, Waters, Zhou, Zibat. Multiple analyses have identified variants potentially created by molnupiravir Fountain-Jones, Kosakovsky Pond, Sanderson,
risk of death, 58.3% lower, RR 0.42, p = 1.00, treatment 0 of 84 (0.0%), control 1 of 210 (0.5%), NNT 210, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
risk of death/hospitalization, 127.0% higher, RR 2.27, p = 0.22, treatment 5 of 84 (6.0%), control 8 of 210 (3.8%), odds ratio converted to relative risk, day 28.

Molnupiravir is among the antiviral agents used to treat COVID-19; however, reported data on the e cacy of this drug are based on results from unvaccinated patients. As such, the e cacy of molnupiravir among vaccinated patients during the B1.1.529 (Omicron) variant outbreak remains unknown. To address this issue, this study retrospectively analyzed data from 294 vaccinated patients with COVID-19 who had at least one risk factor, between May and October 2022. Patients were divided into the molnupiravir group and the control group to investigate the correlations of molnupiravir and other factors with rates of hospitalization and death (hospitalization/death) within 28 days of admission. Potential risk factors were also examined. The study ndings indicated that molnupiravir was not associated with the rate of hospitalization/death, while age ≥ 80 years, residence in a long-term care facility, and presence of chronic obstructive pulmonary disease were signi cantly associated with the rate of hospitalization/death. Although the current results suggest that the effect of vaccination in preventing severe illness against the Omicron variant is well maintained, additional studies on risk factors and outcomes are required to validate this study's ndings.
