The State of Missouri controls the distribution of vaccine in accordance with the federal government plan. How much vaccine comes to Missouri is a decision of the federal government. Missouri cannot order more than the weekly allocation it receives. 

To get the vaccine to its citizens, Missouri has established several distribution systems and a tiered system of eligibility. The first group the State authorized to be vaccinated was Health Care workers and Long-Term Care Facility residents and staff – known as Phase 1A. The second group the State authorized to be vaccinated was Public Safety workers: police, firefighters, corrections workers, known as Phase 1B-Tier 1. The third group the State has authorized to be vaccinated are Phase 1B-Tier 2, those ages 65 and older and adults 18+ with certain health conditions. There are approximately 2.3 million Missourians in Phase 1B-Tier 2, approximately 165,000 of which are citizens of St. Charles County. The State authorized Phase 1B-Tier 3 (critical infrastructure) vaccinations to become eligible on March 15, 2021 and Phase 2 (industries/individuals assisting equity and economic recovery) on March 29, 2021. On April 9, 2021, Missouri authorized Phase 3 to become eligible, enabling all adults in the state - ages 12+ for the Pfizer/BioNTech product and 18+ for the Moderna and Janssen products - to become eligible for vaccination.

The State uses the four St. Louis area hospital systems, the National Guard, federally qualified health centers, local public health authorities (in St. Charles County, that is the County Department of Public Health “DPH”) and registered vaccinators who are unaffiliated with a hospital association or large health care provider. In addition, the State has used pharmacies enrolled in the federal pharmacy program to vaccinate staff and residents in nursing homes and long-term care facilities. The County cannot purchase or obtain COVID-19 vaccine directly; it receives vaccine from the State and is required to use the vaccine within the priorities named by the State Department of Health and Senior Services.

Our residents and businesses are asking us how much vaccine is, or has been, allocated to St. Charles County Department of Public Health. St. Charles County is now beginning to receive more vaccine for distribution, including the Moderna, Pfizer-BioNTech and Janssen from Johnson & Johnson products. The vaccine distribution chart below provides information about distribution and will be updated regularly. The State’s report of total vaccines delivered to County residents through the hospitals and other vaccinators is provided as well.

Receiving a Second Dose of Vaccine

A second dose of the Moderna and Pfizer vaccines is necessary for maximum protection against the virus. FOR THOSE OF YOU DUE A SECOND SHOT, please be aware that authorized vaccine providers in Missouri, including the Department of Public Health, automatically receive and reserve a second dose for all individuals who receive a first dose from their vaccination site. Vaccinated individuals should expect to return to that location at the appropriate time for the second dose — approximately 21 days for the Pfizer/BioNTech product or 28 days for the Moderna product. Locations that did not administer the first dose are not able to administer the second dose, so you will need to return to the original site to receive this vaccination.

The Department of Public Health will contact individuals by email/phone/text of their opportunity to schedule a convenient time for the second dose at the appropriate time. This notification will be sent a few days prior to the vaccination availability and will be sent to the same email/phone/text from which you received your first dose appointment notification. Please be sure to check junk and spam folders for this notification.

State Vaccination Protocols

The Missouri plan allows local public health agencies to apply to be vaccination providers. As a vaccination provider, the state’s rules for vaccine distribution must be followed. The DPH applied for, and is registered with, the State of Missouri as a provider of the COVID-19 vaccines, which have been approved by the United States Food and Drug Administration (FDA).

In December 2020, the Advisory Committee on Immunization Practices (ACIP) recommended, and the State of Missouri adopted, an immunization plan that provides the distribution process begin with those within the Phase 1A category. On Jan. 14, 2021, the state recommended a transition toward the implementation of vaccinations for those in the Phase 1B-Tier 1 and Phase 1B-Tier 2 categories and further clarified groups of individuals eligible for additional phase categories. On March 15, 2021, the state made those in Phase 1B-Tier 3 eligible to receive vaccinations. When additional vaccine becomes available, transition to the next distribution phase will be announced to the public. All phases are now eligible for vaccination in Missouri.
