Individuals who are 18 years and older and received the single-shot Johnson & Johnson vaccine SHOULD get a booster shot (mRNA vaccine is recommended) at two or more months after the initial vaccine. 

Eligible individuals may choose which vaccine they receive as a booster. More information on the CDC’s recommendation for a booster shot is available here.

Second Booster:

Individuals who have had their first booster dose and meet one of the below criteria can choose to receive a second booster shot of an mRNA vaccine four or more months after their first booster shot.

Individuals should bring their vaccination card to their appointment. If individuals do not have their vaccination card, team members will look up their vaccination record prior to administering the booster dose.

KCHD is offering the Pfizer COVID-19 vaccine for people 6 months and older. The CDC recommends:

5 Years and Older: 2 doses of Pfizer-BioNTech in the primary series, given 3–8 weeks apart. People who are moderately or severely immunocompromised (have a weakened immune system) should get a 3rd dose at least 4 weeks after their 2nd dose in the primary series.

6 months through 4 years: 3 doses of Pfizer-BioNTech in the primary series. The first and second doses are separated by three to eight weeks and the second and third doses are separated by at least eight weeks. For people who are moderately or severely immunocompromised (have a weakened immune system), the first and second doses are separated by three weeks, and the second and third doses are separated by at least eight weeks.

If you have questions or concerns, we encourage parents to reach out to their child's pediatrician as they know their child's medical history the best.

If you need a record of your COVID-19 vaccination, KCHD can provide a copy of your record from the Tennessee Immunization Inventory System (TennIIS). This is an official record of your COVID vaccination. We are not able to provide you with another copy of your COVID-19 Vaccination Record Card.

To receive a copy of this record, you may come to the Vital Records Department at 140 Dameron Ave. (first floor) or call the KCHD Public Information Line at 215-5555 for other options or questions.
