@benny171a @lotzof_gas @activia513 @krtmd @jonathanchait Wrong. BA.1 booster had human trials, as did Beta and Delta boosters. The BA.5 is another strain of the exact same vaccine formulation.
@benny171a @lotzof_gas @activia513 @krtmd @jonathanchait 错了。 BA.1 助推器进行了人体试验，Beta 和 Delta 助推器也是如此。 BA.5 是完全相同疫苗配方的另一种菌株。
