Vaccination helps keep those who cannot be vaccinated safe.
Vaccination increases the chance that pathogens will be effective.

Answer 1

Vaccination is important because it reduces the chance of getting sick, prevents pathogens from entering the body, and helps protect those who cannot be vaccinated.

Step-by-step explanation:

Vaccination is important for several reasons:

1. Vaccination reduces the chance of ever getting sick. By introducing a weakened or dead form of a pathogen into the body, vaccines help train the immune system to recognize and fight against the pathogen. This reduces the likelihood of getting sick from that particular disease in the future.
2. Vaccination prevents pathogens from entering the body. When vaccinated, the body develops antibodies that can recognize and neutralize pathogens, preventing them from entering and causing infection.
3. Vaccination helps keep those who cannot be vaccinated safe. There are individuals who cannot receive vaccines due to certain medical conditions. By getting vaccinated, individuals contribute to herd immunity, which helps protect those who are unable to be vaccinated by reducing the spread of diseases within the community.
