Texas health officials are once again asking residents not to wait on the flu shot, pointing to a pattern of hard-hitting respiratory seasons in recent years that have strained hospitals in the state’s biggest metro areas.
State epidemiologist Varun Shetty of the Texas Department of State Health Services has said Texas activity tends to track — and sometimes exceed — national respiratory illness trends, with flu-related emergency room visits historically running highest in Houston and the Dallas-Fort Worth area simply because those are the state’s largest population centers. Shetty noted that most of those emergency visits involve pediatric patients, echoing a pattern seen in earlier severe seasons, when children’s hospitals in North Texas reported emergency department volumes running thousands of visits above the same period a year earlier and wait times stretching up to eight hours.
DSHS has continued its long-standing recommendation that Texans age six months and older get vaccinated by the end of October, noting that it takes roughly two weeks after vaccination for the body to build full antibody protection — meaning the shot needs to happen well before flu activity peaks, not after symptoms start appearing in a household or classroom. DSHS Commissioner Jennifer Shuford has framed vaccination as the state’s best single defense against serious flu illness, alongside routine precautions like covering coughs, frequent handwashing, and staying home from school or work while sick.
Texas does not require a flu vaccine for public school enrollment, and the state has made it easier in recent years for parents to opt out of other school-required vaccines as well, rolling out a downloadable exemption form districts can process directly. That combination — no flu vaccine mandate plus an easier exemption pathway for other vaccines — means vaccination rates going into any given flu season can vary widely by school district and county, which public health officials say makes localized outbreaks and even short-term school closures more likely in under-vaccinated communities.
What it means locally: with flu season typically building through December and peaking anywhere from December to March, Texas health officials’ advice is consistent year to year even as case counts vary: get vaccinated in September or October, not November or December, and keep sick kids home rather than sending them to school “to see how the day goes.” Parents in Houston and DFW in particular should expect emergency rooms to be at their busiest during peak weeks and may want to call a pediatrician’s office or urgent care line first for non-emergency symptoms.
