Answer:
B
Explanation:
Vaccinations prevent sicknesses and transmission of the pathogen by injecting the body with a small amount of the sickness. The body develops antibodies, which prevent the body from developing that disease. If most people in a population are vaccinated, illnesses will spread less quickly because all bodies will have antibodies to fight them. To check, let's use process of elimination.
A: Pathogens are microorganisms that spread diseases, so they should to be encouraged to spread.
C: Although everyone should have access to vaccines, fairness is not as important as keeping the population healthy.
D: Pandemics are disease outbreaks that impact the entire or the majority of the world. Vaccines prevent them, not spread them.
Note: I used the words disease, sickness, and illness interchangeably.
