ISTANBUL -- Turkey announced that the Sinovac Biotech's COVID-19 vaccine is "significantly effective" after analyzing results from the inoculation of more than 7.5 million people with the Chinese doses.
With the efficacy of Chinese vaccines under scrutiny, Health Minister Fahrettin Koca told reporters late Monday that the positive case ratio for people aged 65 and older had halved to 8.2% from 17.7% since the program started in mid-January, and that the ratio for health care workers fell to 1.3% from 5.3%.
