Alice is going to her primary care physician to get vaccinated. Which is a reason that Alice should choose to get vaccinated?

Vaccination helps build immunity in vaccinated people, reducing the spread of infectious diseases. This also protects people who cannot be vaccinated, such as some people with certain medical conditions, because they are less likely to encounter the pathogen. Vaccines do not prevent pathogens from entering the body, and they do not make pathogens more effective.
