Or you can sign up one of the following ways:



Booster doses are currently available to patients who have completed their primary series of vaccinations and it has been more than 2 months since your last dose. Your immunocompromised status will affect the timing of booster doses. Please bring your COVID-19 vaccination card and insurance card (if applicable).

Pfizer and Moderna boosters are bivalent, as of August 31, 2022.


All Missouri residents 6 months of age and older are eligible to receive the COVID 19 vaccine. JCMG has an ample supply of vaccine available (Pfizer, Moderna, Novavax). We are able to schedule patients for vaccinations via telephone, online, or walk-ins.

We also have a limited supply of Novavax COVID-19 vaccine, which is available to Missouri residents 18 years of age and older. Please call us to schedule a Novavax vaccine at (573) 556-7745

Pfizer and Moderna: In order to gain the full effectiveness of the Pfizer or Moderna vaccine, you must receive all doses in its primary series. At the time of your appointment, you can register for follow-up appointments. If you cannot come back on time for your next dose, come back as soon as you can thereafter.

Novavax: The Novavax vaccine is a subunit (or acellular) vaccine—the same type of vaccine which has been well established for decades, such as the Hepatitis B and DTaP (Diphtheria, Pertussis and Acellular Pertussis) vaccines. Its primary series currently consists of two doses. It is not compatible with other COVID-19 vaccines, as either a booster or primary replacement; if you received another COVID-19 vaccine, you are unable to receive the Novavax COVID-19 vaccine. This vaccine is only given on certain dates. Please call ahead at (573) 556-7745 to confirm.


The vaccine itself is free to Missouri residents. However, there may be an administration fee. This administration fee might be covered by your insurance.

Uninsured patients, please bring your ID. Insured patients, please bring your insurance info and ID.


Immediately after receiving the vaccine, you will be required to wait for 15 minutes. If you have a previous history of anaphylactic reaction, you will be required to stay for 30 minutes instead. Most reactions to the vaccine often occur shortly following receiving the vaccine, so we will require you to stick around for a bit to ensure you don’t have an adverse reaction.

The most commonly reported side effects, which typically last several days, are pain at the injection site, tiredness, headache, muscle pain, chills, joint pain, and fever. Often, more people experience these side effects after the second dose than after the first dose. If you experience the aforementioned side effects for more than 48 hours after you received the shot, contact your primary care physician.


You must be free of COVID-19 symptoms and feeling well at the time of receiving the vaccine.


After receiving the vaccine, you will not gain immunity immediately. Weeks after your first shot, you will have some resistance to the virus. Completing a primary series gives you a higher percentage of immunity to the virus.

Additionally, if you become immune to the virus after receiving the vaccine, you can still carry and spread the virus to others who are not immune.


If you need to be tested for COVID-19, JCMG has several options available.

JCMG Express Cares: JCMG offers COVID-19 testing at our Express Care locations. Due to increased demand, waits might vary and be longer than expected. Thank you for your patience as we safely evaluate as many patients as possible.

Purchasable Take-Home Tests: JCMG Pharmacy has tests available for purchase.
