Vaccine Updates

Vaccine Distribution Awareness

We are currently in Phase 1b Tier 1.

Many of you have questions about when you will be eligible for the COVID-19 vaccine. We are currently in Phase 1b Tier 1 of the rollout plan that has been developed with recommendations that closely align with the Advisory Committee on Immunization Practices (ACIP). This includes risk stratification given the limited supply of the vaccine for COVID-19 for the first two months. These guidelines are provided by the CDC.

People who currently have COVID-19 should wait to get vaccinated until they feel better and their isolation period is finished, if possible.

People who were recently exposed to COVID-19 should also wait to get the vaccine until after their quarantine period, if they can safely quarantine away from other people. If there is a high risk they could infect others, they may be vaccinated during their quarantine period to prevent spreading the disease.
