  1. (b) Vaccination (or immunization) is a way to protect people from a disease caused by infection. Years ago, "vaccination" referred only to the smallpox vaccine. Now, vaccination and immunization mean the same thing to most people.
  2. (b) Getting vaccinated is often called "getting your shots." Other names for immunization and vaccination are: needles, baby shots and vaccines.
  3. (b) The word "flu" comes from the word "influenza". Influenza is an infection in the throat and lungs. It is caused by the influenza virus. The problem with this virus is that it spreads easily from person to person in the spray from coughs and sneezes.
  4. (a) "Contagious" means that a disease is easy to get and easy to spread.
  5. (a) An epidemic is when many cases of the same disease happen at the same time among a lot of people. It could also be called an outbreak.
  6. (c) There are two ways to get immunity: by natural infection and by vaccine. Both produce almost the same results.
  7. (a) Children with chickenpox will have a rash that feels very itchy. The illness also causes fever, headache, and aches and pains.
  8. True. The chickenpox vaccine was approved for use in Canada in 1998.
  9. True. Measles spreads very easily from person to person. Children are contagious before anyone even knows they have measles. Children with measles may infect others for 8 days (4 days before the rash appears and 4 days after).
  10. (a) A "booster" is a repeat immunization that helps protect people, over time, against a certain disease. Many vaccines protect people for a very long time. With other vaccines, you must have a repeat shot called a "booster".
