No, IPV is NOT better in all ways. And your link verifies that fact. Specifically IPV only protects you from serious illness. OPV stops transmission. Therefore where polio is endemic, you need to supply OPV to end transmission. Once polio is no longer endemic, IPV guarantees protection without the additional risks that OPV brings to those around who are immunocompromised or not immunized.
