Practice questions testing deep understanding of immunity, vaccination, and antiseptics.
Q1. A child receives an oral polio vaccine (OPV) containing weakened polio viruses. A few weeks later, the child is exposed to the actual wild, dangerous polio virus but does not get sick. Explain the biological role the weakened virus played in providing this protection.
Q2. Assertion (A): Disinfectants and Antiseptics are both chemicals used to kill disease-causing microbes, but they cannot be used interchangeably. Reason (R): Antiseptics are mild enough to be applied to living human tissue (like wounds), whereas disinfectants are strong, toxic chemicals applied only to non-living objects (like floors and toilets).
