The number of vaccinated employees at a COVID-19 treatment hospital in Ho Chi Minh City diganosed with the respiratory disease jumped to 53 on Sunday after a score were detected a day before.
An additional 31 employees at the Ho Chi Minh City Hospital for Tropical Diseases tested positive for the novel coronavirus on Sunday as the institution finished screening all 887 staff members.
