What are the two main vaccines used against poliovirus?

Explanation:
Two vaccines are used to prevent poliovirus: the inactivated polio vaccine (IPV) and the oral polio vaccine (OPV). IPV uses killed virus given by injection and provides strong systemic immunity, protecting against paralysis. OPV uses a weakened live virus given by mouth and induces mucosal immunity in the gut, helping to stop transmission in communities. The combination of these two vaccines is why both IPV and OPV are listed as the main vaccines against poliovirus. The other options miss one of the vaccines or point to an unrelated vaccine, which doesn’t address poliovirus protection.
