• Immune system produces memory cells to specific antigen

Question 2

Many are Vaccines Needed?

Answer 2

• Many communicable diseases can be controlled by behavioural or environmental methods
  1) Ex. STI’s can be controlled by condom use
  2) Ex. Cholera can be controlled by proper sanitation
• When these methods fail:
  ~ Bacterial diseases can be treated with antibiotics
  ~ Viral diseases generally cannot be cured
  VACCINES ARE THE BEST WAY TO CONTROL DISEASES FOR WHICH THERE IS NO CURE
