 Vaccine Information

The vaccine administered by the Union County Health Department may be  Moderna or Pfizer brand vaccine. The EUA fact sheets for both Moderna and Pfizer are located in the links at the bottom of this page.

  • This is a 2 dose vaccine series with doses one month apart. You should receive the same brand of vaccine. We will hold second dose clinics for those we vaccinate.  You will be notified of how to make an appointment for your second dose via the email you provide (unless no email is available).
  • This Moderna vaccine can be used in people 18 years and over and the Pfizer vaccine can be used in people 16 years and over per the FDA EUA.

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 for both the Moderna and Pfizer COVID-19 Vaccines 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 that both the Moderna and Pfizer COVID-19 Vaccine could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to one hour 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 both the Moderna and Pfizer COVID-19 Vaccine. Serious and unexpected side effects may occur. The Moderna and Pfizer COVID-19 Vaccines are still being studied in clinical trials.
