以下为英文原文： WHO Responds to Vaccine Report in China
WHO is aware of reports of vaccines beingpurchased by a private family and resold to hospitals and clinics.Chinese authorities are currently investigating the case and will madethe results publicin coming days. WHO awaits the investigation results and stands readyto provide support to national health authorities.
Vaccines need to be store and managed properly or they can lose potency and become less effective.It is important to note， however， that improperly stored or expired vaccine seldom if ever causes a toxic reaction – therefore there is likely to be minimal safety risk in this particular situation.The risk to children is lack of protection from the disease for which the vaccine was intended.
Vaccines used in China’s Expanded Program on Immunization are known to be safe and effective， and have eliminated polio and neonatal tetanus and reduced vaccinepreventable diseases to very low levels in China.WHO encouragesparents continue to protect their children from vaccine preventablediseases through China’s routine Expanded Program onImmunization.
