COVID19 vaccination training module Flashcards
What is the initial infectious period for COVID19
- asymptomatic
- symptomatic
asymptomatic - anytime really
symptomatic - up to 3 days before symptoms started
When is COVID19 viral load at its highest, and when does it start improving
highest on first day of symptoms, decreases within 7 days
route of transmission for COVID19
- primary route
- other routes
- primarily droplet transmission from close contacts with disease
- can be airborne transmission and fomites, but these are thought to be less prevalent
how long are COVID19 fomites thought to live for
up to 72 hours in normal environments
groups at highest risk of COVID19 exposure (4)
- international travel crew (air + maritime)
- international border staff
- quarantine workers and associated support staff
- frontline healthcare workers
groups at increased risk of contracting COVID19 (4)
- aged care facilities
- disabled
- group residential settings
- detention facilities
2 most important risk factors for severe outcome in COVID19
- age (biggest)
- chronic disease
what is the risk distribution for COVID19 by age
its a cumulative sliding scale ie the older your age, the bigger your risk
for standard vaccines, the 3 main ways vaccines accrue damage are
- being frozen
- being too warm
- UV exposure
what temperature does the Pfizer/BioNTech vaccine need to maintain stability? How long is it stable at this temperature
-70deg C, stable for 6 months
How long can the Pfizer/BioNTech vaccine be stored at regular vaccine temp (2-8C)
5 days, but they are applying for 14 days now
What duration of time should there be between a covid19 vaccination and other vaccines
don’t administer it within 14 days of another vaccine
don’t give another vaccine within 14 days of covid 19
estimated asymptomatic COVID19 infections
18-42%
covid19 estimated incubation period
average of 5-6 days from exposure
can be 1-14 days
covid19 - patients at high risk of severe disease or mortality (5)
- age > 70
- bone marrow transplant in past 24 months
- haematological cancer diagnosed in previous 5 years
- immunosuppression from solid organ transplant or GVHD
- chemo or radiotherapy
