Quan chức Trung Quốc thừa nhận vắc xin Covid-19 nội địa hiệu quả không cao | Thế giới

Phát biểu tại hội nghị ở thành phố Thành Đô ngày 10.4, Giám đốc CCDC Cao Phúc nói rằng tỷ lệ bảo vệ của vắc xin Covid-19 do Trung Quốc sản xuất là không cao nên nhà chức trách đang cân nhắc có nên trộn các loại vắc xin lại với nhau, theo AP.

Đây được cho là lần đầu tiên một nhà khoa học hàng đầu của Trung Quốc công khai thảo luận về hiệu quả thấp của các vắc xin của nước này.

Trung Quốc đã xuất khẩu hai loại vắc xin nội địa gồm Sinovac và Sinopharm ra 22 nước. Tuy nhiên, độ hiệu quả của Sinovac trong việc ngăn ngừa triệu chứng chỉ đạt mức 50,4%, theo nghiên cứu tại Brazil. Vắc xin của Pfizer-BioNTech (Mỹ-Đức) hiệu quả đến 97%.

Theo ông Cao, Trung Quốc đang cân nhắc 2 giải pháp gồm điều chỉnh liều lượng, thời gian nghỉ giữa hai lần tiêm và gia tăng số lần tiêm.
