COVID-19 Vaccine Booster

In accordance with the Food and Drug Administration and the Centers for Disease Control and Prevention, Hattiesburg Clinic is now offering an additional COVID-19 booster shot for people ages 50 and older and those 12 and older with underlying medical conditions to increase protection against severe disease from COVID-19.

Eligible patients may receive either the Pfizer-BioNTech or Moderna® mRNA booster four (4) months after their last dose. Adults who received a Johnson & Johnson’s Janssen® COVID-19 booster may also receive an additional booster using an mRNA COVID-19 vaccine four (4) months after their last dose.

HealthWorks Immunization Clinic continues to offer the Pfizer vaccine booster for ages 12 and older, and the Moderna and Johnson & Johnson’s Janssen boosters for everyone ages 18 and older.

Those who received the Pfizer or Moderna COVID-19 vaccine should get a booster at least six (6) months after completing their primary COVID-19 vaccination series.

Individuals ages 18 and older who received the Johnson & Johnson COVID-19 vaccine two (2) or more months ago, should also receive a booster dose.

Patients 18 and older can choose to receive a different vaccine booster than their primary series. Appointments may be booked through Iris, Hattiesburg Clinic’s patient portal, or by
calling (601) 261-1620.

COVID-19 Vaccines

COVID-19 vaccines are available to persons aged 5 years and older through HealthWorks Immunization Clinic.

Patients can schedule first-dose appointments the following ways:

  • Through Iris, Hattiesburg Clinic online patient portal
  • By calling their Hattiesburg Clinic physician’s office,
  • By calling (601) 261-1620

Patients who would like to schedule an appointment for their second dose or booster vaccine, appointments should be scheduled through Iris. Patients can only schedule an appointment for the booster vaccine if they meet certain criteria.  Click here to learn more.

Who Should Be Vaccinated When Eligible

Due to the volume of phone calls, patients are encouraged to schedule their appointments through Iris. Appointments are available on a first-come, first-served basis.

  • Eligible individuals 5 and older are eligible to receive a vaccine*.
  • Those under 18 should talk to their health care provider about vaccination rather than visiting an MSDH drive-through site.
  • Pregnant women, lactating women and those who are immunocompromised may take the vaccine; however, consultation with your health care provider is recommended.
  • You can be vaccinated if you have tested positive for COVID-19 if you wait until your isolation period is over and your symptoms have significantly improved.

*Healthworks Immunization Clinic is only able to offer the brands of vaccines that have been made available to the clinic.  Once all appointments have been claimed, scheduling will be closed. To schedule your appointment online or to sign up for Iris, please click here.

Thank you for understanding as we continue to protect our patients and community.

HealthWorks Immunization Clinic

HealthWorks Immunization Clinic, a service of Hattiesburg Clinic and Forrest General Hospital, began offering COVID-19 vaccines to eligible groups on Monday, Jan. 11, 2021. Patients will be able to schedule an appointment through their Iris account. Appointments cannot be made by phone at this time.

For patient convenience, we ask that you fill out the Centers for Disease Control and Prevention (CDC) questionnaire and vaccine consent form prior to your appointment. Click to download the questionnaire and consent form. Please bring your completed forms with you to your appointment.

HealthWorks Immunization Clinic has been vaccinating health care professionals since Monday, Jan. 4, as a part of the first phase of the Mississippi State Department of Health’s (MSDH) COVID-19 vaccine rollout plan.

The current vaccination options from Moderna and Pfizer consist of a series of two doses, three to four weeks apart, where the first dose primes the immune system to fight the virus and the second boosts the production of antibodies. These vaccines can neither give a person COVID-19 nor does the mRNA interact with the DNA of a person’s cells.

Side effects may include short-term, normal responses such as headache, chills, fatigue, muscle pain or fever that only last for a day or two. A very small percentage of people developed short-lived symptoms at the site of injection. These are normal, healthy responses that indicate your body is building immunity to COVID-19.

Hattiesburg Clinic Medisync® Clinical Research was the sole clinical trial site in Mississippi for the Moderna vaccine, which is one of the available options, and helped gather data to provide evidence of 94.5% efficacy in preventing COVID-19.

HealthWorks Immunization Clinic will continue to offer the COVID-19 vaccine as long as it’s in supply.

As your trusted health care partners, Hattiesburg Clinic is committed to your health and safety. If you would like to learn more about the COVID-19 vaccine, please visit www.hattiesburgclinic.com/coronavirus.

Hattiesburg Clinic providers, Drs. Batson, Henderson, Liddell, Rouhbakhsh and Stewart, join to discuss the COVID-19 vaccines. Watch this conference to learn how the vaccine works, vaccine safety and effectiveness and who should receive it and projected timelines for vaccination.
