中国国家首席兽医师、农业部兽医局局长贾幼陵15日说，中国目前正在对全国范围内的家禽接种疫苗，费用由中央和地方政府共同支付。据悉，我国“人用禽流感疫苗研制”项目已完成临床前研究，这标志着我国在这一领域取得重大突破。请看报道： Jia Youling, chief veterinary officer in China's Agriculture Ministry, said China is in the process of vaccinating all poultry in the country. He said the government will pay all fees involved, but he did not provide any details of how officials would carry out the vaccinations. Vaccinate的意思就是“（给…）接种疫苗”，也就是我们通常所说的“打预防针”，vaccinate常和against连用，表示“接种疫苗以预防（疾病）”，如：When were people first vaccinated against measles?（人们首次接种麻疹疫苗是什么时候？） 此外，vaccine指的是“疫苗”，而“（接种）疫苗者”则称为vaccinee。 （中国日报网站编）
