d) What type of disease can be prevented through vaccination?​

Answer 1

Answer:

1. Immunization is the process of giving a vaccine to a person to protect them against disease. Immunity (protection) by immunization is similar to the immunity a person would get from disease, but instead of getting the disease you get a vaccine.
2. Immunity: Protection from an infectious disease. If you are immune to a disease, you can be exposed to it without becoming infected. Vaccine: A product that stimulates a person's immune system to produce immunity to a specific disease, protecting the person from that disease.
3. A vaccine is a substance that helps protect against certain diseases. Vaccines contain a dead or weakened version of a microbe. It helps your immune system recognize and destroy the living microbe during a future infection.
4. The most common and serious vaccine-preventable diseases tracked by the World Health Organization (WHO) are: diphtheria, Haemophilus influenzae serotype b infection, hepatitis B, measles, meningitis, mumps, pertussis, poliomyelitis, rubella, tetanus, tuberculosis, and yellow fever.
