COVID-19 Vaccine for Adolescents and Teens: What Parents Should Know

NOTE: This COVID-19 post is over a year old and may contain outdated information. It has been left up for archival purposes only. For the most up-to-date information on masking, vaccines, and more, visit the CDC’s website.

This blog was published in May 2021. As of June 2022, the FDA has authorized the emergency use of the Pfizer COVID-19 vaccine in children ages 6 months to 4 years. Additionally, it authorized the emergency use of the Moderna COVID-19 vaccine in children 6 months to 5 years.

The FDA authorized the emergency use of the Pfizer COVID-19 vaccine in children ages 5 to 11 in November 2021.

Last week, the FDA authorized the emergency use of the Pfizer vaccine in 12-to-15-year-olds, and the CDC recommended its use in this age group. If you have children 12 and older, here are eight things to know about COVID-19 vaccination in adolescents and teens:

1.  The Pfizer vaccine is safe.

The Pfizer vaccine is safe for children aged 12-15 years and teens aged 16 and older. Thousands of teens and children participated in the clinical trials to show that the vaccine is safe for 12-year-olds and older. 

Teens aged 16-17 were among the thousands of volunteers who participated in the clinical trials that started a year ago. Those trials, coupled with the results from millions who have already been vaccinated, show that the Pfizer vaccine is safe and is 95% effective in preventing COVID-19. 

2. The vaccine works in adolescents.

During the clinical trials, 2,250 volunteers between the ages of 12 and 15 participated, and they found no cases of COVID-19 among fully vaccinated adolescents. 

3. Mild side effects are normal.

Adolescents reported side effects similar to adults in the clinical trials. The main side effect reported in this age group was a sore arm. Some may experience tiredness, muscle aches, or headaches. Side effects are a sign that the immune system is learning how to recognize and fight the COVID-19 virus. 

4. Children can get COVID-19.

Even though children are at a lower risk of severe disease from COVID-19, it doesn’t mean that there is no risk. Children can spread COVID-19 to others who may be more at risk for severe disease from COVID-19.

Additionally, some children have gone on to develop multisystem inflammatory syndrome (MIS-C) from COVID-19 infection. 

5. Vaccinated people can safely enjoy the activities they love.

Once fully vaccinated, adolescents and teens can safely participate in activities without the need to wear a mask, social distance, or quarantine if exposed. Starting vaccination now means they’ll be fully vaccinated come summer, and able to do more of the things they’ve been missing — such as socialize with their vaccinated friends and return to sports, camps, and activities.

Despite the loosening of some restrictions, COVID-19 transmission is still possible until enough of the population is vaccinated. Getting vaccinated can give both you and your child peace of mind.

6. How to make an appointment.

Many locations throughout the Kansas City metro have the Pfizer vaccine. Parents or legal guardians can bring their children who are aged 12 and older to vaccination sites, clinics, and pharmacies. You can find the Jackson County Health Department’s COVID-19 clinics at or other vaccination sites at

In most situations, a parent or guardian will need to sign a consent form and be present when their child is vaccinated. 

7. What to expect at a COVID-19 vaccination appointment.

After getting checked in, the nurse will ask your child some questions about their health. They will receive the vaccine and will be asked to wait for 15 or 30 minutes afterward to monitor for reactions. After this, your child will be given a vaccine record card indicating when and where they received the vaccine and when their second dose is due.

8. Where to go if you have additional questions.
