声称疾控中心（CDC）已经花费12.4亿美元购买新冠疫苗的说法完全错误。

所引用的合同是无限交付/无限数量（IDIQ）合同，这些合同是在季节到来之前就已设立，以确保在需要时有可用供应。

卫生与公众服务部（HHS）和疾控中心尚未为即将到来的呼吸道疾病季节购买新冠疫苗，也没有就未来的采购做出任何决定。

允许未来订购的IDIQ合同并不等同于花费纳税人的钱。

The claim that CDC has already spent $1.24 billion on COVID-19 vaccines is simply wrong.

The contracts cited are indefinite delivery/indefinite quantity (IDIQ) contracts put in place ahead of the season to ensure availability if needed.

HHS and CDC have not purchased COVID-19 vaccines for the upcoming respiratory season and have made no decisions regarding future purchases.

IDIQ contracts allowing future orders are not the same as spending taxpayer dollars.
