BREAKING: Pfizer to ask FDA for emergency use authorization of a 3rd booster dose.

It's possible that another dose may provide more lasting + better protection against emerging variants, especially for older individuals.

加强针就等于说辉瑞对Delta保护不力，否则为什么还要加强，而且还要紧急批准

现在的新冠疫苗都是紧急批准的

you know nothing about FDA process

FDA和CDC联合声明：目前情况不需要打第三针，现有疫苗仍然足够有效。
