Pediatric COVID-19 Vaccination FAQs

Should I vaccinate my child?

Yes, everyone age 5 and older should get vaccinated against COVID-19 as soon as possible. Although fewer children have been infected with COVID-19 compared to adults, children can:

  • Be infected with the virus that causes COVID-19
  • Get very sick from COVID-19
  • Experience both short and long-term health complications from COVID-19
  • Spread COVID-19 to others

Did you know?

  • COVID-19 vaccines have been tested under the most intensive safety monitoring in U.S. history.
  • Your child cannot catch COVID-19 from the Pfizer COVID-19 vaccine.
  • Children with underlying medical conditions are more at risk for severe illness from COVID-19.
  • Children who get infected with the virus that causes COVID-19 can also develop serious complications like multisystem inflammatory syndrome (MIS-C)—a condition where different body parts become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, or gastrointestinal organs.

Booster Doses

Many available vaccines require boosters. Booster doses help increase your child's immune response, which may decline over time. Kids age 5 and older are eligible for a Pfizer-BioNTech COVID-19 vaccine booster 5 months after completion of their primary vaccination series. Currently, kids under age 5 are not eligible for a booster dose.

Third Doses

For some immunocompromised children aged 5–11 years old, CDC now recommends an additional dose of the Pfizer-BioNTech COVID-19 vaccine to complete the primary series – a total of three doses. Learn more.

MaineHealth practices are currently giving third doses to those who need them. If your child age 5-11 years old is moderately or severely immunocompromised and you have not already been contacted, please call your MaineHealth family doctor or pediatrician for more information.

Age 12-18: Visit one of our walk-in vaccination clinics anytime within the posted hours for your first COVID-19 vaccine dose. We'll help you schedule your second dose appointment while you are there. Online scheduling is also available at some locations.

Age 5-11: MaineHealth is offering COVID-19 vaccination appointments for children aged 5-11 at some of our pediatric practices. Online scheduling is available here.

Both the Pfizer Age 12+ vaccine and the Pfizer Age 5-11 vaccine require a second dose approximately three weeks (or 21 days) after the first dose.

Kids age 5-11 who receive their first COVID-19 vaccine dose at a primary care office will need to return to the same office for their second dose.

Kids and teens who receive their first COVID-19 dose at a MaineHealth practice or walk-in vaccination clinic will need to return to the same location for their second dose. We'll help you schedule the second dose appointment during the first dose appointment.

Booster Dose Appointments

Contacting your family doctor or pediatrician is the most convenient way to schedule a booster dose appointment for your child.

  • Online self-scheduling for booster shot appointments is available at some MaineHealth locations.
  • We also offer booster shots on a walk-in basis at some locations.
  • You may also call 877-780-7545 to schedule a MaineHealth COVID-19 booster shot appointment at select locations.

  • No serious side effects have been detected in the ongoing study.
  • Nearly half of all kids 12 - 17 years old in the U.S. have been fully vaccinated. That's more than 11 million kids who have had both of doses of the COVID-19 vaccine.
  • The vaccines continue to be monitored very closely.
  • Per CDC guidance, COVID-19 vaccines will have the most intensive safety monitoring in U.S. history.

Like many vaccines, COVID-19 vaccines may cause mild side effects, like a sore arm, body aches, headache, a fever, or tiredness for a day or two. These are signs that your child’s immune system is responding to the vaccine and building immunity to the virus. They are not a cause for concern.

Short Term Side Effects

  • On the arm where the shot is given:
    • Pain, Redness, Swelling
  • Throughout the rest of the body:
    • Tiredness, Headache, Muscle pain, Chills, Fever, Nausea
  • Your child may feel badly enough that they don’t feel like doing their normal daily activities.
  • You can give your child Tylenol (acetaminophen) or Advil (ibuprofen) AFTER the shot to reduce pain or fever, unless you’ve been told by your doctor not to. 
    • DO NOT give your child a fever reducer or pain reliever before the shot to prevent symptoms.

Soreness of Fever

  • If your child’s arm is sore, you can put a clean, cool wash cloth or covered ice pack on their arm to reduce soreness.
  • Moving or exercising the arm may reduce soreness.
  • If your child has a fever, they should drink plenty of fluids to stay hydrated and dress lightly.

Second Dose

  • Your child can still get the second dose even if they had these symptoms from the first shot
  • You can use the V-safe health checker ( to tell the CDC about any symptoms your child had after getting the COVID-19 vaccine

Serious side effects are extremely rare. The risk of serious illness or death from COVID-19 infection is much greater.

  • Cases of myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the outer lining of the heart) have been reported after Pfizer-BioNTech COVID-19 vaccination of children ages 12–17 years. These reactions are rare; in one study, the risk of myocarditis after the second dose of Pfizer-BioNTech in the week following vaccination was around 54 cases per million doses administered to males ages 12–17 years.
  • A severe allergic reaction, like anaphylaxis, may happen after any vaccine, but this is rare.
  • Your child will be monitored for allergic reactions after their first and second vaccine doses. Licensed clinicians will be on site to manage any adverse reactions.

Yes, your child may get a COVID-19 vaccine and other vaccines, including the flu vaccine, at the same time. In fact, the American Academy of Pediatrics (AAP) supports kids getting routine immunizations at the same time as, or close to when they, get a COVID-19 vaccine. This is especially important if kids missed getting some vaccines during the pandemic.
Yes, kids and young adults can and should get a vaccine even if they have had COVID-19. After they are fully recovered from illness due to COVID-19, vaccination can help protect kids and young adults from getting sick again.

There are no known risks to getting the vaccine after being infected with coronavirus. And, it is thought that people get better protection by being fully vaccinated compared with just having had COVID-19.
Kids and teens are considered fully vaccinated two weeks after their second dose of the Pfizer vaccine. After that, it is important to continue practices that help limit the spread of COVID-19. For example, you and your child or teen should still wear a mask indoors in public settings to protect yourself and others.

Occasionally, a vaccinated person may get infected with the virus or even get mild symptoms. This is called a "breakthrough infection." But, the vaccine is very good at preventing serious illness, hospitalization, and death due to COVID-19.

Learn more about what you and your child or teen can do after being fully-vaccinated.

It is a smaller dose (one third) of the same vaccine that has been approved for use in people age 12 and older. The formula has been tested specifically for children ages 5-11 years old.
