Vaccine Information

The vaccines currently administered by the Union County Health Department are the Pfizer and Johnson & Johnson vaccine. The EUA fact sheets are located in the links at the bottom of this page.

  • The Pfizer vaccine can be administered to people 12 years of age and older. It is a 2 dose vaccine series with doses 21 days apart. You should receive the same brand of vaccine. We will administer a second dose to those we have given a first dose. Your second dose will be scheduled at the time of your first dose appointment. A booster dose is recommended for many people six months after their second dose.
  • A pediatric version of the Pfizer vaccine for children age 5-11 years old has received FDA authorization and is recommended by the CDC  This is a smaller two dose series with doses 21 days apart.
  • The Johnson & Johnson vaccine can be administered to people 18 years of age and older. It is a one dose series. A booster dose is recommended two months after the first dose.

Tell your vaccination provider if you have any medical conditions, including:

  • any allergies
  • a fever
  • a bleeding disorder or are on a blood thinner
  • immunocompromised or are on a medicine that affects your immune system
  • are pregnant or plan to become pregnant
  • breastfeeding
  • have received another COVID-19 vaccine

Side effects that have been reported after COVID-19 vaccination include:

  • Injection site reactions: pain, tenderness and swelling of the lymph nodes in the same arm of the injection, swelling (hardness), and redness
  • General side effects: fatigue, feeling unwell, headache, muscle pain, joint pain, chills, nausea and vomiting, and fever

There is a remote chance the COVID-19 vaccines could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to four hours after getting a dose of either COVID-19 Vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received your vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include:

  • Difficulty breathing
  • Swelling of your face and throat
  • A fast heartbeat
  • A bad rash all over your body
  • Dizziness and weakness

These may not be all the possible side effects of COVID-19 vaccines. Serious and unexpected side effects may occur. The COVID-19 vaccines are still being studied in clinical trials.

V-Safe: Post Vaccine Check-In

V-safe is a smartphone-based tool that uses text messaging and web surveys to provide personalized health check-ins after you receive a COVID-19 vaccination. Through v-safe, you can quickly tell CDC if you have any side effects after getting the COVID-19 vaccine.

At the vaccination clinic, you will receive information on how to register for V-Safe. To learn more about this program, please visit
