Flu Vaccine Doses Administered
Percentage Vaccinated
Getting the flu vaccine is the first and most important step you can take to protect yourself and your loved ones. The flu vaccine is safe for individuals 6 months and older; free to most Delawareans, even if you do not have insurance. It is very important for groups at higher risk, such as seniors, women who are pregnant, young children, and people with chronic health conditions; and something you should get every year.
The best way to reduce your risk from seasonal flu and its potentially serious complications is to get vaccinated every year. For most people who need only one dose of flu vaccine for the season, September and October are generally good times to be vaccinated against flu. Ideally, everyone should be vaccinated by the end of October.

The data in this section are about vaccinations administered to residents of Delaware. Population numbers used for vaccination rates are estimates (Source: 2021 American Community Survey 5-year Estimates).
Due to natural shifts in the population over time, these population estimates may over or underrepresent the actual population for any demographic group and, as a result, the percentage of people vaccinated within any demographic group may be slightly higher or lower than the true value.

Combining information about a community's general vulnerability to the harms of disasters — like disease outbreaks and natural events — with current influenza vaccination coverage (percentage of persons vaccinated) can help support and prioritize vaccination efforts. This map provides such an assessment, depicting CDC social vulnerability data with local vaccination coverage — dark blue regions indicate low vaccination levels in more vulnerable communities; lighter shades of blue indicate more widely vaccinated populations. The goal is to increase the number of census tracts displaying lighter blue colors representing increased vaccination coverage in all communities throughout the state.
