Flu season in the United States runs from October through May, with peak activity occurring between December and February. Public health officials say that the annual flu shot remains the best defense against infection and severe illness. DPH recommends that everyone ages 6 months and older who is eligible, should receive the vaccine as soon as possible.
It takes approximately two weeks after vaccination for the body to build full immunity, health leaders stress the importance of getting vaccinated early before viral spread ramps up across the state.
Each year, flu-related complications lead to an average of 250 deaths in South Carolina, including four pediatric deaths.
Flu vaccines are widely available at local pharmacies, primary care clinics, and healthcare providers statewide.
For South Carolinians who are uninsured or whose insurance policies do not cover vaccination costs, no-cost flu shots may be available through DPH clinics. Residents can check eligibility by calling DPH’s Care Line at 1-855-472-3432 or by utilizing DPH's online vaccine finder tool.
The onset of flu season coincides with ongoing respiratory threats, including COVID-19. DPH advises residents to consult with their primary healthcare providers to determine which seasonal vaccines are recommended for their individual health needs.
In addition to vaccination, DPH strongly recommends several core preventive measures to help curb the spread of respiratory illness:
- Wash hands frequently with soap and water for at least 20 seconds
- Cover coughs and sneezes using a tissue or the inside of your elbow
- Stay home and isolate from others whenever feeling unwell
DPH tracks state-level influenza data year-round and publishes updated surveillance data every Wednesday through its Flu Watch report, which is available on the DPH website.
