· Recommended to use existing vaccination structures and delivery services as much as possible for distribution of the COVID-19 vaccines
· Important to consider cold-chain requirements when developing distribution plans
· Should consider alternate locations for hard-to-reach populations that are easily accessible and familiar
· Consider branching out to mobile vaccination (e.g. home visits, door-to-door), pharmacies, workplaces, congregate living facilities, walk-up/drive-through mechanisms for vaccine delivery

Screening tools commonly include fever, respiratory symptoms (cough, shortness of breath), and epidemiological risk factors.
· The sensitivity and specificity of screening questionnaires depends considerably on the items used in the questionnaire. The limited published literature demonstrates great variability in the performance of different screening tools: sensitivity ranges from 0 – 48.6 – 84.3 – 100%; specificity ranges from 64.8 – 71.3 – 89.6 – 96%).
· The standard WHO symptom checklist performs poorly, with a sensitivity of 48.6%, and specificity of 89.6%. As such, half of individuals who have SARS-CoV-2 present at the time of testing will be missed by the symptom questionnaire (being either asymptomatic or presymptomatic). Depending on the population being screened the prevalence of the virus may vary widely. Given the sensitivity and specificity of the WHO symptom checklist in a population with prevalence ranging from 0.1% to 1% to 10% the positive predictive value (PPV) will be poor, range from 0.4% to 4.8% to 35%, respectively. Furthermore, the performance characteristics of the screening questionnaire may be poorer than reported if used in a setting or time of year when other respiratory viruses with similar symptoms are circulating.
