Why is CCDPH recommending vaccines for pregnant or breastfeeding people and kids 12 and up, but not for kids under 12?

Data shows the benefits of COVID-19 vaccination for all people 5 years and older, including people who are pregnant, breastfeeding, trying to get pregnant now, or might become pregnant in the future. The benefits of COVID-19 vaccination outweigh the known and potential risks. For more information, visit: https://www.cdc.gov/coronavirus/2019-ncov/vaccines/recommendations/pregnancy.html
