Step-by-step explanation:
The "FP" on a vaccine label typically stands for Feline Parvovirus, which is a disease that can affect cats. Feline Parvovirus, also known as feline panleukopenia, is a highly contagious viral illness. When discussing vaccines, it's important to note that they are biological preparations that provide active acquired immunity to a particular infectious disease. For instance, the vaccine developed by Hilary Koprowski was designed to prevent polio, a highly infectious viral disease. Another serious viral infection is rabies, which can affect both humans and other animals and is typically transmitted through the bite of a rabid animal.
