Antibiotics can cure illnesses caused by viruses.

Circle one:   True   False

What does a vaccine contain?

• A full strength live germ
• A harmless weakened germ or fragment
• A dose of antibiotics

What is herd immunity?

• Wide immunity starving outbreaks of new hosts
• One person catching every illness once
• Animals passing germs to people

Why does finishing the full antibiotic course matter for everyone?

• Stopping early spares partly resistant bacteria that then spread
• Longer courses taste better
• Leftover pills expire quickly

Why does the second meeting with a germ end before symptoms start?

• The germ becomes weaker over time
• The skin grows thicker after illness
• Matching antibodies are already filed from training

A hospital overuses one antibiotic and a resistant strain appears. How did it evolve?

• The drug turned viruses into bacteria
• Patients became immune to the drug
• The drug killed the weak, leaving resistant mutants to multiply

A town vaccinates widely against a bacterial disease and antibiotic use falls. Why does resistance slow as a side effect?

• Vaccinated people absorb antibiotics faster
• Vaccines kill resistant bacteria directly
• Fewer infections mean fewer antibiotic courses doing the selecting

A student writes: my body got used to penicillin, so the drug stopped working for me. What is the error?

• Penicillin works against viruses too
• Resistance evolved in the bacteria, not in the student
• Vaccines and antibiotics are the same thing
