- Question 1Recall
Weakened or killed pathogens introduced into the body to trigger the immune system are called
- aimmunogens
- bantibodies
- ctoxins
- dhormones
- Question 2Extended thinking
A public health official argues that funding immunisation programmes is not just a health investment but an economic one. Using the benefits described in the curriculum, justify this argument.
- aImmunisation reduces disease-related mortality and hospitalisation, which lowers healthcare costs; it also protects the workforce and supports uninterrupted education, both of which support broader economic growth and productivity
- bImmunisation has no economic effects, only health effects
- cImmunisation increases healthcare costs without any offsetting benefit
- dEconomic benefits only apply to wealthy countries, never to disease-endemic regions
- Question 3Extended thinking
A newborn baby has some short-term protection against diseases the mother has previously been immune to, without ever receiving a vaccine. A few months later, the baby receives its first scheduled vaccinations. Explain the difference in the type of immunity at each stage and why the second stage is needed.
- aThe newborn initially has passive immunity from antibodies passed by the mother, which is temporary and wanes; the vaccinations at a few months provide active immunisation, triggering the baby's own immune system to produce longer-lasting antibodies
- bBoth stages provide identical, permanent immunity with no difference
- cThe mother's antibodies last a lifetime, so vaccination is unnecessary
- dVaccination at a few months provides only passive immunity, same as from the mother
