Q

benefits of influenza vaccine

A

prevents 7 million cases of illness per year and 110,000 influenza-related hospitalizations and 9,000 deaths prevented (with most deaths being in children, elderly, and pregnant women)

Q

benefits of pneumonia [pneumococcal] vaccine

A

pneumonia death rate = 1 in 20 (1 in 5 if they develop septicemia or meningitis complication)

40,000 deaths per year, 50% could be prevented if everyone got the vaccine

mortality risk is greatest in early childhood, elderly, and underlying medical conditions

two options: Prevnar, Pneumovax

Q

when should a vaccine dose be deferred or delayed?

A

moderate-severe illness with or without fever (her personal rule is that the only time she will skip a vaccine that is due is when she is sending that person to the hospital)

do NOT need to defer in the presence of minor illness

Q

what is active immunity

A

given via vaccine

resistance is developed in response to a vaccine, usually characterized by the presence of an antibody produced by the host

given in anticipation of exposure to an infecting agent

onset of protection is usually within 1 month of the dose

protection usually lasts years or lifelong

Q

what is passive immunity

A

given via immune globulin

immunity is conferred by an antibody produced in another host, via administration of an antibody-containing preparation (antiserum or immune globulin [IG])

given post-exposure to select infecting agents

onset of protection is usually within hours of dose

duration of protection is time limited, usually 6-9 months

available for only a limited number of infectious agents

anaphylaxis is an acute, life-threatening systemic reaction that results from the ....
sudden systemic release of mediators from mast cells and basophils
28

IV access if available, oxygen, ongoing clinical monitoring (do not leave them alone in the exam room)
30

36
previously unvaccinated adults with newly diagnosed T1DM or T2DM should be vaccinated against ______ as soon as possible d/t risk for contracting from their glucose testing
hepatitis B higher risk of developing chronic hepatitis B people with DM in a group setting (e.g., hospital, LTAC), there are outbreaks of Hepatitis B from caregivers who did not properly disinfect the testing equipment or not changing the lancet
37
for routine tetanus immunization UPDATE (booster) in adults, which version should you use?
either Td or Tdap is ok
38
discuss PCV13 vs. PPSV23
PCV13 = stronger protection, more narrow coverage PPSV23 = broader coverage, less strong protection both tend to be pretty well-tolerated
39
anticipatory guidance for patients regarding pneumococcal vaccine adverse reactions
30-50% will experience local reactions including pain and redness systemic reaction (fever, myalgia) is rare, highest in children (11-40% of children will have short-term mild systemic reaction) severe reactions are rare
40
what is a live attenuated vaccine
live, weakened virus vaccine prepared from live microorganisms that are cultured under adverse conditions leading to loss of virulence but retention of their ability to induce protective immunity

live vaccines most commonly used in the US (4)

42
difference between zostavax and shingrix for zoster vaccination?
zostavax (old version) was a live vaccine (no longer being manufactured). was only 50% efficacious shingrix is NOT LIVE!!! nearly 100% efficacy :)
43
in which populations do we avoid live vaccine use? (2)
- pregnancy d/t theoretical risk of passing along virus to fetus - severe immunocompromise d/t potential risk of becoming ill with the virus or a lack of clinical effect (e.g., HIV with AIDS, on immunemodulators)

45
if someone had zostavax in the past, should they still receive shingrix?
yes, shingrix is more efficacious

if someone had shingles in the past, should they still receive shingrix?
yes, can prevent severity and post-herpetic neuralgia wait 6-8 weeks after last outbreak before giving
47
