Keep our immunity strong with the updated COVID-19 booster, now eligible for everyone 12 years+.

Staying current on COVID-19 vaccines, including primary series and booster doses, protects against the worst outcomes of COVID-19 for many months following vaccination. The FDA authorized the updated booster after reviewing data showing the booster improved protection against currently circulating variants.

Vaccines for Infants, Toddlers, and Children

In California, it is recommended that everyone aged 6 months and older get a COVID-19 vaccine, and everyone aged 5 and older get a booster dose when eligible, to help protect against severe outcomes of COVID-19. Vaccinating children can help protect family members who are at higher risk for getting sick. Vaccination can help keep kids in school and safely participating in group activities. The Pfizer-BioNTech and Moderna vaccines have been authorized for children aged 6 months and older. COVID-19 vaccine dosage varies by the age of the child on the day their vaccine dose.

Pfizer

  • The Pfizer-BioNTech vaccine for children contains the same active ingredients as the vaccine given to people aged 12 and older.

  • Youth aged 12 and older receive the same dose as adults.

  • Children aged 5 – 11 receive a lower dose than those 12 and older.

  • Infants and toddlers aged 6 months – 4 years receive a lower dose than children aged 5 – 11.

Moderna

  • The Moderna vaccine for children contains the same active ingredients as the vaccine given to people aged 18 and older.

  • Youth aged 12 – 17 receive the same dose as those aged 18 and older.

  • Youth aged 6 – 11 receive a lower dose than those aged 12 – 17.

  • Infants and toddlers aged 6 months – 5 years receive a lower dose than children aged 6 – 11.

The COVID-19 vaccine has been proven safe and effective for children based on data from clinical trials. All COVID-19 vaccines continue to be rigorously monitored.

  • People have rarely experienced severe health effects after COVID-19 vaccination.

  • Children may experience side effects like pain and swelling where the shot was given, or headache, fatigue, and fever. These symptoms should go away in a few days.

Pfizer-BioNTech 3-dose series

Boosters

Everyone aged 5 and older is eligible to receive a booster dose. Everyone 12+ who has had their primary series should get the updated booster at least 2 months following any COVID vaccine or booster dose.

Pfizer-BioNTech and Moderna

  • Those aged 5-11 years should receive a booster (monovalent) dose of Pfizer-BioNTech, at least five months following the completion of their primary series.

  • Those aged 12-17 years should receive the Updated Booster (bivalent) dose of Pfizer-BioNTech, at least two months after receiving their last dose, regardless of type (primary series or booster).

Pregnancy and Fertility

Evidence continues to build that COVID-19 vaccination during pregnancy is safe and effective. The CDC recommends COVID-19 vaccine for people who are pregnant, breastfeeding, trying to get pregnant now, or could become pregnant in the future. There is currently no evidence that any vaccines, including COVID-19 vaccines, cause fertility problems. Pregnant and recently pregnant people are more likely to get severely ill with COVID-19 than non-pregnant people. Research continues to show that getting COVID-19 during pregnancy increases the risk of complications that can affect your pregnancy and developing baby, including newborn mortality, such as preterm or stillborn infant. Talk to your doctors if you feel hesitant about getting vaccinated against COVID-19 to learn the medical and scientific facts.
