Tdap Vaccine Recommendations:
The Tdap vaccine protects against tetanus, diphtheria, and pertussis. The Tdap vaccine is recommended for children 11-12 years of age and is required for all children entering the 7th grade in Virginia.
More information about the Tdap vaccine can be found here: https://www.cdc.gov/vaccines/hcp/vis/vis-statements/tdap.html
All vaccine data on this page are reflective of doses reported to Virginia's Immunization Information System (VIIS). There may be vaccines administered to people that are not reflected in VIIS, and there may be vaccines administered to people reported in VIIS who are no longer residents of Virginia. VDH has set the maximum coverage rates displayed at 95% for this dashboard due to possible imprecision in the population estimates, as the denominator for these is census single-race population estimates. The data is refreshed weekly on Tuesdays and represents the selected age as of the refresh date.
Data is suppressed when the count of the number vaccinated is between 1-9, to preserve anonymity.
Population estimates data source: 2023 American Community Survey (ACS) population estimates.
*No population estimates are available for out-of-state individuals or those without a reported locality. More information about the population estimates can be found at this link - https://www.census.gov/programs-surveys/acs
Some vaccine records were missing due to a database sync issue. It was fixed on 11/23/2025, and monitoring is in place by VDH to avoid similar issues in the future.
