Manama: Bahrain's health regulator announced that it has officially approved the registration of a Covid-19 vaccine developed by the China National Pharmaceutical Group, or Sinopharm, a state media report said.
"Results from Phase III clinical trials showed an 86 per cent efficacy rate, a 99 per cent seroconversion rate of neutralising antibody and 100 per cent effectiveness in preventing moderate and severe cases of Covid-19, following testing on 42,299 volunteers," the report added.
Bahrain, which had participated in Phase III clinical trials of the vaccine in August, authorised the emergency use of Sinopharm's vaccine in November to cover those frontline professionals in contact with Covid-19 patients.
