COVID-19 Vaccine

Vaccine Distribution Phases

DuPage County is starting to transition COVID-19 vaccine distribution from Phase 1a to Phase 1b. Hospitals and outpatient sites enrolled as COVID-19 vaccine providers will continue to prioritize healthcare workers, especially non-hospital based healthcare workers in Phase1a, for vaccination. Starting January 25, vaccination providers may begin vaccinating individuals in Phase 1b including individuals that are over 65 years old and frontline essential workers who live or work in DuPage County.

DuPage County Health Department’s COVID-19 vaccine clinics will continue to focus on providing vaccine to Phase 1a healthcare personnel, by appointment only. As vaccine supply increases over time and additional vaccination sites become available, the Health Department expects the rate of vaccination will increase and more information will be available about the specific locations people will be able to contact to schedule appointments for vaccine.

Estimated Population and Vaccination Timeline

COVID-19 Vaccine Phases and Planning in DuPage County

There will be a phased roll-out of the COVID-19 vaccine in DuPage County with a very limited supply at the beginning, so certain groups will be prioritized. Everyone is encouraged to get vaccinated as soon as it’s their turn. Supplies will increase over time and all adults will be able to get vaccinated later in 2021. Once a vaccination phase begins, people in that phase are eligible to receive the COVID-19 vaccine indefinitely.  Tentative dates are dependent on vaccine supply.

Why Prioritize certain people?

Many healthcare personnel have a high risk of being exposed to and getting sick with COVID-19. Early vaccine access is critical to ensuring the health and safety of this essential workforce of approximately 21 million people, protecting not only them but also their patients, communities, and the broader health of our country.

When will I know it is my turn?

What phase are we in?

DuPage County Health Department has been following federal and state guidance regarding COVID-19 vaccination priority, beginning vaccination with ACIP Phase 1a including healthcare workers and residents of long-term care facilities. Beginning Monday, January 25th, DuPage County will transition to Phase 1b including frontline essential workers and people 65 years of age and older.

Is there wasted vaccine?

DuPage County Health Department has implemented protocols to ensure vaccine is not wasted in DuPage County.

Why Prioritize certain people?

Beginning Monday, January 25th, DuPage County will transition to Phase 1b. This means we will begin to ramp up vaccination for DuPage County residents over 65 years old and frontline essential workers. Based on the limited supply of COVID-19 vaccine across the country and coming to DuPage County each week we anticipate it may take approximately 12 weeks to vaccinate the nearly 270,000 individuals in DuPage County who meet Phase 1b criteria.

How will 1b be vaccinated?

Over the coming months, people will be able to access vaccines through a health care provider, retail pharmacies, the Health Department, and many other locations.  As the vaccine supply increases, much more information will be available from all of these providers about vaccine scheduling.
