Loudoun Now Offering COVID-19 Vaccine Booster Appointments for Ages 12 and Up

Posted on January 6, 2022 at 12:41 PM by Nancy McCormick

Loudoun County is now offering appointments for booster doses of the Pfizer COVID-19 vaccine for people 12 to 15 years of age at its Dulles Town Center clinic. This follows the expansion of COVID-19 booster recommendations by the Centers for Disease Control and Prevention (CDC) and authorization of a wider use of the Pfizer vaccine by the Food and Drug Administration. 

The Virginia Department of Health is adopting the latest CDC recommendations, which include a shortening of the interval when people who have had the initial series of Pfizer vaccine can get a booster shot from six months to five months, and a third primary series dose for some children ages 5 to 11 who are immunocompromised. 

Individuals who are 12 and older and who received their second dose in the two-dose series of the Pfizer vaccine at least five months ago are eligible for the booster. The Pfizer vaccine is the only COVID-19 vaccine currently approved for ages 17 and under. While the county has expanded booster vaccinations to include this age group, the number of available appointments for people 12 and over is currently limited due to high demand.

As the Omicron variant of the virus continue to spread, health officials say vaccination remains the best protection against COVID-19. “Loudoun County, as well as our whole region, is now at the highest level of COVID-19 transmission,” said Loudoun County Health Director Dr. David Goodfriend. “Those who are unvaccinated remain at the highest risk of severe illness and hospitalization due to COVID-19.”

Vaccination Eligibility 

In addition to booster doses of the Pfizer vaccine for those 12 and older, Loudoun County is offering COVID-19 vaccination appointments for: 

  • First and Second Doses: People ages 5 and older who have not yet received their first and/or second dose of COVID-19 vaccine.
  • Boosters: People ages 18 and older who received the second in a two-dose series of Pfizer vaccine at least five months ago, Moderna vaccine at least six months ago, or who received the J&J vaccine at least two months ago.
    • Mix and Match’ Boosters: Any of the three approved vaccines may be used as a booster, regardless of the product used in the initial vaccine series. For example, if someone’s primary series was Pfizer, they are eligible for Moderna, Pfizer or J&J vaccine as a booster after five months.  Conversely, if the initial series was Moderna, they are not eligible for a booster until six months even if that booster shot is Pfizer. Someone who received the one-dose J&J vaccine could receive any vaccine as a booster after two months.

Know When You’re Eligible for a Booster Dose 

With the CDC guidance calling for booster doses to be administered at least five months  after the second dose of the Pfizer vaccine, six months after the Moderna vaccine and two months after the J&J vaccine, it’s important that people know when they completed their initial series so that they can appropriately time a booster. 

You can find the date you completed the initial series on your vaccination card. If you received that dose in Virginia and have misplaced the card, you can find the date by searching for your vaccine record online. If you need assistance over the phone, call 866-375-9795. Assistance is available Monday through Friday from 8:30 a.m. to 5:00 p.m. 

The Virginia Department of Health has added a scannable QR code to vaccination records. The technology allows anyone vaccinated in Virginia to show proof of vaccination with a digital or printed QR code instead of a paper card. If you have moved to Loudoun from another state since receiving your second dose of Pfizer or Moderna or dose of J&J, you should check with the health department for your previous jurisdiction for your vaccination record.
