  1. 1Immunisation is [blank_start]controlled exposure[blank_end] to a vaccine to produce immunity (protection) against a disease. It primes the immune system to generate [blank_start]memory[blank_end] immune responses. Vaccines are predominantly given by [blank_start]injection[blank_end]. A vaccine can stimulate [blank_start]sterilizing immunity[blank_end] (pathogen can not establish in future) or [blank_start]partial protection[blank_end] (pathogen can establish in future but disease will be sub -clinical or very mild).
    1. Acontrolled exposure
    2. Bmemory
    3. Cinjection
    4. Dsterilizing immunity
    5. Epartial protection
  2. 2Choose the best description of immunological memory.
    1. AThe ability of the immune system to respond more rapidly and effectively to pathogens that have been encountered previously.
    2. BThe ability of the immune system to recognise pathogens which it has previously encountered.
    3. CThe ability of the immune system to recognise pathogens which the biological parent's immune systems had encountered previously.
  3. 3Choose the incorrect answer about memory B cells.
    1. AThey make IgM rather then IgG (isotype switched)
    2. BThey have a high affinity Ig (affinity matured)
    3. CThey have high precursor frequency (due to clonal expansion)
    4. DThey already express activation molecules
  4. 4Choose the incorrect statement about memory T cells.
    1. AThey have a high precursor frequency
    2. BThey are already differentiated (Th1, Th2)
    3. CThey already express activation molecules
    4. DThey have low affinity TCRs (T cell receptors)
  5. 5Misconception #1: Natural exposure is ‘better'
    It is not. Natural exposure is much more [blank_start]dangerous[blank_end] and can be very [blank_start]painful[blank_end] and even life threatening, putting kids in hospital.
    Misconception #2: ‘All you need to do is eat & live healthy’
    Even a healthy and fit person can be overwhelmed by the [blank_start]sheer numbers[blank_end] of a pathogen and their immune system won't be able to fight it off.
    Misconception #3: Vaccines are not safe
    Vaccines are incredibly safe. There is evidence that some vaccines are associated with serious adverse effects; however, these events are [blank_start]extremely rare[blank_end] and must be weighed against the [blank_start]protective benefits[blank_end] that vaccines provide.
    Misconception #4: It is sanitation that decreased number of infection, not vaccines
    False, as case reductions this [blank_start]significant and large[blank_end] (ie 98.2% - 100% reductions) could not be produce just by better sanitation, and some case statistic reductions occurred fairly [blank_start]recently[blank_end].
    Misconception #5: Majority of people who get diseases are vaccinated
    This is cherrypicking of data which is only [blank_start]common sense[blank_end]. If the majority of the population is vaccinated, the majority of cases of infection will be from vaccinated people. However, the ratio of unvaccinated people getting infected will be much larger compared to the ratio of vaccinated people getting infected ie vaccination does decrease chance of infection.
    1. Adangerous
    2. Bpainful
    3. Csheer numbers
    4. Dextremely rare
    5. Eprotective benefits
    6. Fsignificant and large
    7. Grecently
    8. Hcommon sense
  6. 6New Zealand's target for immunisation coverage is 95% of children are fully immunised by 2 years of age.
    1. AVerdadero
    2. BFalso
  7. 7We can improve coverage and get high uptake of vaccines via:
    - [blank_start]Education[blank_end]
    - Active [blank_start]follow up[blank_end]–National Immunisation Register (NIR)
    - Improved [blank_start]access[blank_end] (ie expand delivery sites to the workplace, maraes, pharmacies)
    1. AEducation
    2. Bfollow up
    3. Caccess
  8. 8Pharmacists can now provide free influenza immunisation to < 65’s.
    1. AVerdadero
    2. BFalso
