Diabetes is a high-risk factor for developing severe case of Covid-19. Success of different strategies to stop the COVID-19 epidemic depend heavily on whether COVID 19 is a bioweapon spread clandestinely or if its a naturally occurring infection spread randomly. Recently the US department of defense stated that COVID-19 pandemic may be a bioweapons attack. One way to help determine if the COVID-19 outbreak is a bioweapons attack is to determine if there is evidence of activity to immunize select groups prior to the release of COVID-19. Data included suggest MMR vaccination may help protect against COVID-19 and is supported by an independent group doing a different analysis. The potential benefits of the MMR vaccine on COVID-19 and the urgent efforts to immunize with MMR leading up to the COVID-19 outbreak need further investigation.
