Manila Mayor Francisco "Isko Moreno" Domagoso said during his live broadcast over Facebook on Monday night that several doctors, nurses, and laboratory personnel are confirmed to be infected and reinfected with the coronavirus disease 2019 (Covid-19). Doctors and nurses deployed in vaccination sites were asked to return to their mother units and facilities to assure continuity of services in the six district hospitals. He asked for the public's patience for the slowdown in the vaccination program but assured inoculation and free swab tests will continue despite the reduced number of HCWs. Among the infected are 14 personnel of the Sta. Ana Hospital molecular laboratory. As of Tuesday
