HA NOI (VNS)— Quinvaxem vaccine was safe and effective for continued use in Viet Nam, World Health Organisation (WHO) Representative in Viet Nam Takeshi Kasai confirmed at a press conference in Ha Noi yesterday.
The remark was made after the vaccine, used against the childhood infections such as diphtheria, tetanus, whooping cough, hepatitis B, and Haemophilus influenzae type b, was suspended temporarily in Viet Nam following a series of child fatalities.
Kasai said that Viet Nam should continue to use the vaccine as part of the National Expanded Programme for Immunisation (EPI) for the benefit of people's health, especially children.
He said test results showed that Quinvaxem vaccines collected from the field in Viet Nam complied with the quality specifications stated by WHO.
The tests were performed by a WHO contracted laboratory, the National Institute of Biological Standardisation and Control in the United Kingdom.
According to WHO, the tests were requested by Viet Nam to confirm the quality of the vaccine distributed by the Berna Biotech Korea Corporation following cases of adverse reactions and test results obtained by the Viet Nam National Control Laboratory.
EPI Director Nguyen Tran Hien also affirmed that among the 43 cases of adverse reactions associated with Quinvaxem since 2010, only 9 were found to be directly related to the vaccine and those patients had recovered. The 27 fatalities had been attributed to other causes or the findings were inconclusive.
Tran Dac Phu, deputy director of the Ministry of Health's Preventive Medicine Department said that the ministry would ask the Government to resume the use of Quinvaxem soon.
According to WHO, the Quinvaxem vaccine had been used in more than 90 countries worldwide with over 400 million doses since 2006. — VNS
