Can we take tdap/dtap with pertussis vaccine again? i took this vaccine maybe 5 years ago and again i took yesterday. i'm 21 years old now so is it harmful that i took this vaccine with pertussis again? also can i take covid vaccine in few days?

Tdap (with the acellular pertussis component) is the adult formulation. The acellular pertussis vaccine, developed and given now for decades does not have the side effect problem of the old whole cell Pertussis vaccine we used before the 90's. It is often given in preparation for pregnancy or to expectant families to protect the newborn. It does not interfere with the Covid vaccine effectiveness.
