Three doctors at a mental health hospital in Vietnam have been diagnosed with COVID-19, while two of them had already received their first vaccine shots.
The doctors, aged 27, 34, and 46, work at Nghe An Mental Hospital in north-central Nghe An Province, according to the provincial Center for Disease Control.
Two of them previously received their first COVID-19 vaccine doses on May 4.
The three doctors tested negative for the novel coronavirus twice on June 18 and 21.
However, their third tests came back positive on June 30.
Nghe An Mental Hospital has been fenced off since a health worker caught COVID-19 on June 17.
Her six family members were later confirmed to have been infected with the virus.
A total of 435 people, including the three doctors, have been quarantined at the infirmary since then.
Vietnam has documented 17,902 coronavirus cases as of Friday afternoon, with 7,274 recoveries and 81 deaths, according to the Ministry of Health.
The country has recorded 14,505 local infections in 51 provinces and cities since a new transmission wave began on April 27.
Nghe An has detected 105 cases in this bout, whereas more than 44,000 people in the province have received COVID-19 vaccination.
