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 Ministry¹, said China is in the process of vaccinating² all poultry³ 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 vaccinations⁴.

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 vaccinated⁵ against measles⁶?（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。
