When to Get a Flu Shot in North Texas

Most flu shot advice is written for a national average. North Texas does not follow the national average particularly well, and that has a practical consequence for timing.

The tension

Two facts pull against each other.

Protection from the vaccine wanes over the months following the shot, more noticeably in older adults. And influenza activity in Texas frequently peaks later than the national curve, often deep into winter and sometimes stretching into February or March.

Get vaccinated in early August and protection may be measurably weaker by the time our actual peak arrives. Wait until January and you have been unprotected through a stretch when the virus was already circulating.

The practical answer

Late September through October is the target for most adults. That places the strongest part of the response over the window when influenza activity here is typically climbing and peaking.

Do not push it into December waiting for perfect timing. The risk of missing the shot entirely is larger than the benefit of optimizing it. People who plan to go in November frequently do not.

If it is already January and you have not gone, go. Vaccination while the virus is still circulating still prevents illness. There is no point at which “too late” becomes a reason to skip it, until the season is genuinely over.

Adults 65 and older should ask specifically about the higher dose or adjuvanted formulations, which are preferentially recommended for that age group.

Who should particularly not skip it

Annual influenza vaccination is recommended for essentially everyone six months and older, with rare exceptions. The case is strongest for:

• Adults 65 and older
• People with chronic heart or lung conditions, including asthma and COPD
• People with diabetes, kidney disease or liver disease
• People with weakened immune systems
• Pregnant people
• Anyone living with or caring for someone in the groups above

That last one gets overlooked. If you are the person who visits your mother three times a week, your vaccination is partly about her.

What the shot does and does not do

It reduces your chance of getting influenza, and when it does not prevent infection it tends to reduce severity, hospitalization and complications. Effectiveness varies year to year depending on how well the strains in the vaccine match what actually circulates.

It does not protect against COVID-19, RSV or the ordinary common cold, which is the source of a great deal of “the flu shot did not work” frustration. Most winter illness is not influenza.

Getting one

We give flu shots during any visit, including an annual physical, which is the easiest way to do it since you are already here. If you only need the shot, that is a short appointment.

Worth checking your insurance first, though preventive vaccines are covered in full by most plans. Our insurance page lists what we accept, and you can book a visit.
