There are currently three vaccines authorized by the U.S. Food and Drug Administration under Emergency Use Authorization. Two are two dose vaccines, requiring a booster at 21 days and 28 days, respectively. The third is a one-dose vaccine.

Recipients must receive the same vaccine for both the first and second doses. Your vaccination provider will give you a card with the manufacturer's name and other critical information you will need for a second dose. If you miss your second dose, please get it as soon as possible after the 21- or 28-day recommendation. Learn more about the benefits of getting vaccinated and what to expect during your vaccination appointment.

Some Kansans are eligible for boosters once they have completed their vaccine series. For the booster dose, Kansans may receive either the same type of vaccine as they received originally or they can choose another type depending on availability.

Ethics & Availability

While the vaccine supply is limited, it will be made available based on ethical principles of maximizing benefits, minimizing harm, striving for equity, justice and fairness, and making transparent decisions. Kansans who have been disproportionately impacted by the COVID-19 pandemic will be prioritized. Additionally, the state of Kansas is vetting vaccine providers before they receive an allotment of vaccines. Learn more.
