Question

alice is going to her primary care physician to get vaccinated. which is a reason that alice should choose to get vaccinated? vaccination reduces the chance of ever getting sick. vaccination prevents pathogens from entering the body. vaccination helps keep those who cannot be vaccinated safe. vaccination increases the chance that pathogens will be effective.

Explanation:

Vaccination does not prevent pathogens from entering the body or reduce the chance of ever getting sick completely. Also, it does not increase the chance that pathogens will be effective. However, vaccination helps in herd immunity. When a large number of people are vaccinated, it creates a protective barrier for those who cannot be vaccinated (such as people with certain medical conditions). This is because if most of the population is immune, the pathogen has fewer hosts to infect, thus protecting the vulnerable unvaccinated individuals.

Answer:

Vaccination helps keep those who cannot be vaccinated safe.
