Find a vaccine appointment for your child

Children age 5 years and older can get a COVID-19 vaccine. Vaccines are the strongest layer of protection we can offer children against COVID-19. This fall, COVID-19 rates have been higher in school-aged children than adults. While fewer children get severely ill with COVID-19 than adults, they still can get sick with the virus and spread it to other people. Some get sick enough to need hospitalization. Getting a COVID-19 vaccine can help your child stay healthy, keep them in school, and protect your family and community.

The COVID-19 vaccine is free. You don’t need ID or insurance for you or your child to get vaccinated.


Where can my child get vaccinated?

Children age 12 to 17 years can get a vaccine at any provider that has the Pfizer vaccine. You can find providers with Pfizer on our vaccine finder webpage or on You can also text your ZIP code to 438829 or call 1-800-232-0233 to find locations near you.

Many medical offices will soon begin offering COVID-19 vaccines for children age 5 to 11 years. Ask your child’s medical provider if they plan to offer COVID-19 vaccines in their office.
Children age 5 to 11 years can now get a COVID-19 vaccine at pediatric clinics around the state. Find upcoming clinics for children. Some doctor’s offices and pharmacies are also now taking vaccine appointments for children. Find a list of COVID-19 vaccine providers for children age 5-11. We will add more providers to this list as they open up appointments. 

Beginning Friday, November 5, CDPHE is partnering with Children’s Hospital Colorado to offer vaccines for children age 5 to 11 years. Adults and children age 12 and older may also receive COVID-19 vaccines at these clinics on a walk-in basis while supplies last.

View the calendar below to find clinic dates and sign up for an appointment for your child in advance. Please note that appointments at these clinics fill up quickly. We are thrilled so many parents are making appointments to vaccinate their children ages 5-11. Although many slots are already full, we will have ample supply of the vaccine for younger children and are confident that any Colorado parent who wants to get their child vaccinated will be able to do so soon.

We will continue to add new clinics to this calendar. Please check back for more dates.

Please note that each appointment is for one child only. Unless they have an appointment, children will not be allowed to enter the facility. Do not leave children or pets unattended in the car or on campus. Please arrange child care for any of your younger children while you take your age-eligible child to their vaccine appointment. 

Is it safe for my child to get vaccinated?

Yes. Clinical trials show that it is safe for children age 5 to 17 years to receive a COVID-19 vaccine. Millions of children age 12 to 17 years have already safely been vaccinated against COVID-19, and more than 2,000 children age 5 to 11 years have safely received a vaccine in a clinical trial. 

Do children get the same type of vaccine as adults? 

Children age 12 to 17 years can get the same kind of Pfizer vaccine as adults. Children age 5 to 11 years will get a smaller dose of the Pfizer COVID-19 vaccine. This vaccine is one third of the dose of the Pfizer vaccine used for teens and adults. 

How well does the vaccine work for children?

Pfizer’s clinical trials showed that the vaccine for children age 12 to 15 years was 100% effective in preventing COVID-19 infection. The vaccine for children age 5 to 11 years was about 90% effective in preventing COVID-19 infection. Both vaccines were 100% effective in preventing severe disease and death. 

What are the side effects of the vaccine for children?

The side effects in children are similar to the side effects experienced by adults. They can include tiredness, headache, soreness, chills, and fever. In clinical trials, children age 5 to 11 years tended to have milder side effects than teens and adults. Most side effects are mild and go away on their own after a day or two.

Will my child need two doses of the vaccine?

Yes. Be sure to schedule your child’s second dose 21 days or three weeks after the first dose.


Can my child get routine vaccines at the same time as the COVID-19 vaccine?

Yes. It is safe for your child to receive other routine vaccines on the same day as a COVID-19 vaccine. You may be able to include other routine vaccinations at the appointment, which are vital for keeping kids protected from other illnesses. 


Do children need to be accompanied by a parent or guardian at their vaccine appointments?

The state of Colorado does not require minors to be accompanied as long as parental consent is collected and shared prior to the appointment. This can be done through Colorado’s COVID-19 Vaccine Screening and Administration Form (view in Spanish) or through the vaccine provider’s online scheduling system. The provider may also obtain consent by phone and document it in the patient’s record.

Some vaccine providers may require children to have a parent or guardian with them at their appointment. We recommend calling your provider ahead of time to check whether they require parental accompaniment.
