Is the COVID-19 vaccine safe for my infant or toddler?
Yes, it’s safe. Safety experts from the CDC and FDA have carefully reviewed months of clinical trial data and found that the vaccine is safe and effective for this age group.

Which COVID-19 vaccine can kids get and is the dosage different for younger ones?
All children ages 6 months to 17 years can receive either the Pfizer-BioNTech vaccine or the Moderna vaccine. While they are the same, exact vaccines made with the same, exact mRNA technology that is used in older children and adults, the dose is different depending on the specific age range.
Pfizer dosing for children
- Children 6 months-4 years: Just three micrograms per shot, given in two shots, spaced three weeks apart, then:
- A third dose of Pfizer is required two months after the second dose for children 6 months to 4 years
- Children 5-11 years: Just 10 micrograms per shot, a third of the dosage for adolescents and adults. The vaccine is also given in two shots, spaced three weeks apart.
- Children 12-17 years: 30 micrograms per shot, the same dosage for adults. As with adults, the vaccine is given in two shots, spaced three weeks apart.
Moderna dosing for children
- Children 6 months-6 years: Just 25 micrograms per shot, given in two shots, spaced one month apart.
- Children 6-12 years: 50 micrograms per shot, half of the dosage for adults. The vaccine is also given in two shots, spaced one month apart.
- Children 12-17 years: 100 micrograms per shot, the same dosage for adults. As with adults, the vaccine is given in two shots, spaced one month apart.
Please note: right now, there is no required third dose for the Moderna vaccine.
Are the Pfizer and Moderna vaccines as effective for children 6 months to 4 years as they are for older kids?
Yes. We have seen many more small children hospitalized in this latest COVID-19 surge than in previous surges and unfortunately more than 1,000 children have died of COVID-19 in the United States alone. These vaccines have been shown to be highly effective in reducing severe illness and hospitalizations from COVID-19.

What was Pfizer and Moderna's testing process for the vaccine in this age group?
Several thousand children were given either the vaccine or a placebo and then closely followed for months.
Two-thirds received the vaccine, and the other third received a placebo for comparison. Over a number of months, Pfizer and Moderna tested different dosages to find the best one for this age group’s immune system.
Does the COVID-19 vaccine cause any new or different side effects for those 6 months to 4 years?
No. In the 24 hours after their shot, younger kids, toddlers and infants may experience the usual short-term side effects: a sore arm, fever, chills or headache. This is similar to what we’ve seen in young children, adolescents and adults.
Keep in mind that many other vaccines, like the flu shot, have similar side effects. Not everyone experiences them, but when they do, it’s just a normal sign of the body’s immune system working. Side effects are usually mild and go away in about a day.
