Recommended Immunization Schedule Analysis
Class work: 1) Take a look at the next couple slides on the
‘Recommended Immunization Schedule’ and make a list of the vaccines that every child takes from 0-6 years old, and from 7-18 years old.
2) How many vaccines should you have had by now, according to the immunization schedule?
3) Do these vaccines protect you from infectious or non-infectious diseases? Explain.

a) B lymphocytes:
b) T lymphocytes:

How do the cells work? (Active or Passive immunity)
Active immunity• Gained by:
• Our body produces:
Passive immunity• Gained by:
• Our body does not produce antibody, instead it:
• Example:

ANTIBODIES ARE BIOLOGICAL WEAPONS. HOW DO THEY KILL THE PATHOGEN?

ANTIBODIES• Structure: ____________________• Produced by: _________________• Function: ______________________________________________________________________________• This causes one of two things to happen: 1) _______________________________________
Or 2) _______________________________________

ANTIBIOTICS or ANTIBACTERIALS• Antibiotics are used to: __________________________________________________________________• _____________________________________________________________________________________• There is concern worldwide that antibiotics are
_____________________________. Antibiotic overuse is one of the factors that contributes towards _______________________________ as the growing number of bacterial infections which are becoming _____________________________.
