Coronavirus | Vaccine Information
COVID-19 vaccination information for kids & teens
The U.S. Food and Drug Administration (FDA) has authorized the emergency use of the Pfizer BioNtech and Moderna vaccines to prevent COVID-19 in children 6 months and older. The FDA has authorized the Johnson & Johnson vaccine for people 18 and older. The Centers for Disease Control and Prevention (CDC) prefers that people get either a Moderna or Pfizer vaccination as a booster shot and recommend a Johnson & Johnson vaccine only in certain situations.
Vaccine dosages and inoculation cycles vary:
- The Pfizer vaccine is given in three doses to children between 6 months and 4 years old. Children 5 years and older receive the Pfizer vaccine in two doses.
- The Moderna vaccine is given in two doses to children between 6 months and 17 years old. A third dose is authorized for children with certain conditions that weaken their immune systems.
- The Johnson & Johnson vaccine is given in one dose.
Who is eligible for a COVID-19 booster?
COVID-19 vaccine boosters can enhance or restore protection that might have diminished over time after your primary series vaccination.
- People ages 5 years and older should get one booster shot after completing their COVID-19 vaccine primary series.
- Two booster shots are recommended for adults ages 50 years and older, and people ages 12 years and older who are moderately or severely immunocompromised.
Getting your child vaccinated
At Boston Children’s, we’re vaccinating eligible patients against COVID-19 at our Longwood campus in Boston, as well as periodically at satellite locations and the Martha Eliot Health Center.
While we are eager to be a vaccine resource, we encourage you to take advantage of any opportunity to schedule a vaccination appointment. It is possible that are sites closer to your home that offer the vaccine too. You can find information about state and local health care organizations offering the vaccine by visiting mass.gov/vaccine.
Because every state is a little different, we encourage Boston Children’s families who live outside of Massachusetts to get vaccinated in your home state as soon as you or your child is eligible. You can search for vaccines near you on the vaccine.gov website.
How do I schedule my child for a vaccine at Boston Children’s?
Please register for the Boston Children’s patient portal to self-schedule an appointment or call 617-919-7102 to connect with a member of our team to schedule a vaccine. Phone lines will be open Monday through Friday between 7 a.m. and 8 p.m.
Is there transportation assistance available for COVID-19 vaccine appointments?
Yes. We will ask you if you need transportation assistance when we contact you to schedule your child’s vaccine.
If your child has MassHealth coverage or the Health Safety Net, including MassHealth Limited, Children’s Medical Security Program (CMSP) and MassHealth Family Assistance (FA), you can arrange free transportation to your child’s COVID-19 vaccine appointment by calling 800-841-2900 (TTY: 800-497-4648). For more information, visit the MassHealth website.
Boston Children’s is providing free parking for all vaccine appointments.
Educating kids about the COVID-19 vaccine
Frequently asked questions about the COVID-19 vaccines
Yes. The Pfizer and Moderna vaccines offer the most protection after the recommended number of doses. (The Pfizer vaccine is given in three doses to children between 6 months and 4 years old.)
Yes. Your child should get the vaccine even if they have already had COVID-19. Even though having had COVID-19 may provide some protection from getting sick again, that protection fades over time.
No. People with COVID-19 can get the vaccine after they are feeling better and meet the criteria to stop isolation. If your child had COVID-19 and had monoclonal antibody or convalescent plasma treatments, they should wait 90 days to get the vaccine. Talk with your child’s doctor about when your child should receive the vaccine.
There is no evidence that the COVID-19 vaccine affects future fertility.
There have been rare and mild cases of a type of heart inflammation called myocarditis in some younger patients who received certain COVID-19 vaccines. Dr. Kristin Moffitt offers more details.
The data we have seen make us confident that the vaccines authorized by the FDA are safe for the ages included in the authorization.
Most new medicines and vaccines are studied in adults first, so the first authorization for the vaccines doesn’t include younger children. Companies are studying the vaccines in younger children, and there will be more information coming on their safety and effectiveness in children. Very rarely, some people have had allergic reactions to the vaccines, which can be treated.
Some people have symptoms, like a sore arm and redness around the injection site, mild-to-moderate headache, muscle aches or fatigue. Some people a low fever after the vaccine and some have nausea and vomiting.
The most common side effects in infants between 6 and 36 months included irritability, sleepiness, and loss of appetite.
These symptoms are normal and usually don’t last more than a day or two. If your child had an allergic reaction after the first dose, please talk to your doctor before getting the second dose.
No. The reason that the COVID-19 vaccines were able to be made so quickly is that the government provided extra money to support the research and production. The quality of the trials and the review of the safety and effectiveness of the COVID-19 vaccines was not different from normal processes for other vaccine approvals.
The number and timing of dozes depends on your child’s age and which vaccine they receive:
- The Pfizer vaccine is given in two doses to children 5 years and older, with the second dose coming three weeks after the first. Children younger than 5 receive the Pfizer vaccine in three doses.
- The Moderna vaccine is given in two doses to children 6 months and older, with the second dose coming four weeks after the first.
- The Johnson & Johnson vaccine is given in one dose to people 18 and older.
Eventually, there will probably be other vaccines available with different schedules.
Many children of different sizes participated in the Pfizer and Moderna clinical trials for children. The FDA reviewed these children’s immune responses in several age ranges and determined that the immune responses to the lower doses recommended for infants and children was very similar to what’s been achieved in older individuals with higher doses of the vaccine.
Families should take reassurance that their older children who might be large for their age are not getting shortchanged in terms of immune response.
Studies of the COVID-19 vaccine have used the same dose and regimen for 12- to 15-year-olds that was used in adults and showed excellent immune responses. Dr. Kristin Moffitt explains.
Vaccine doses purchased with U.S. taxpayer dollars are provided to Americans at no cost. However, some vaccination providers may charge an administration fee.

Coronavirus | Community Resources
Boston Children’s Hospital is committed to improving the health and well-being of children and families in our community. We know that the COVID-19 crisis has caused parents and caregivers to face unprecedented levels of stress in their everyday lives. Many families continue to struggle with food insecurity, are worried about paying their rent or mortgage, have concerns about sending their child to daycare, or how to work with a child learning from home.
Food access and resources
Unfortunately, the COVID pandemic has led to more food insecurity for families throughout Massachusetts. It also has disproportionately impacted those living in low-income areas and the Black and Latino communities.
Boston Children’s is supporting its community partners and Boston community health centers to help families with food access, as well as with other needs around rental and utility assistance, and other basic household supplies.

Childcare and school resources
Boston Children’s Office of Community Health launched the Boston Childcare Support Initiative in July 2020 to support childcare providers in the communities most impacted by COVID. In total, 130 childcare providers have received grants. The grant amounts ranged from $3,500 to $10,000. These funds will be used by childcare providers to follow public health guidelines, adapt physical spaces, and cover increased costs for staff, overhead, personal protective equipment, and cleaning supplies.
We hope these funds will help childcare providers recover, as they are essential small businesses, providing a critical service for many families in our community. Read more about how Boston Children’s is supporting childcare providers during COVID.

When does a patient require COVID-19 testing?
The Commonwealth of Massachusetts recommends testing for anyone with COVID-19 symptoms and any individual who has had close contact a person with confirmed COVID-19 infection.
A person is considered a close contact if:
- They were less than 6 feet from a person with confirmed COVID-19 for at least 10-15 minutes while the person was symptomatic or within the 48 hours before symptom onset
- They had direct contact with infectious secretions of a person with confirmed COVID-19 while not wearing recommended personal protective equipment (e.g., gown, gloves, facemask, eye protection)
