Explain.

8. Sample Vaccination Report Analysis Class work: Take a look at the next slide titled ‘Immunization Report’ to answer the following questions. • How old is the child in the report? When is his/her birthday? • What vaccinations has he/she had? • Has this child been vaccinated for chicken pox?

10. What is a vaccine? Vaccine: • ________________________________________________________________________________ • Contains a substance that ________________________________________ • It is a ______________form of the pathogen but ________________________________________________________________________________. • The immune system recognizes the pathogen as _________________, ______________, and _________________, so that the immune system can more easily___________________________________ • _____________________________________________
