Which Vaccines Do Adults Need This Fall? A McAllen Doctor's Guide to Flu, COVID, RSV, Pneumonia, and Shingles
Walk into any pharmacy in McAllen in September and a sign will tell you flu shots are available. What the sign will not tell you is whether you also need the pneumonia vaccine, whether your age and your diabetes qualify you for the RSV vaccine, or whether the shingles series you started two years ago was ever finished.
There are five vaccines in play for adults this fall. Almost nobody needs all five. Which ones apply to you depends on your age, the conditions you live with, and what you have already had, and that is a conversation, not a sign.
Here is how to sort it out before flu season arrives.
The Timing: Why September and October Matter
The CDC recommends that most adults get the flu vaccine in September or October, ideally before the end of October. There is a reason for the window on both ends.
Your immune system needs roughly two weeks after the shot to build meaningful protection, so vaccinating after flu is already circulating leaves you exposed during the gap. Vaccinating too early, in July or early August, risks protection waning before the season peaks, which in the United States usually falls somewhere between December and February.
If it is already November and you have not been vaccinated, get vaccinated anyway. Flu activity often continues into March and sometimes May. Later is far better than never.
The Five Vaccines on the Table
| Vaccine | Who It Is Generally For | How Often |
|---|---|---|
| Influenza (flu) | Everyone 6 months and older, with rare exceptions | Every year, the formula is updated annually |
| COVID-19 | Recommendations have moved toward shared decision-making with your doctor; benefit is greatest for adults 65+ and people with weakened immune systems | Annually updated formula |
| RSV | Adults 75 and older; adults 50 to 74 with increased risk, including chronic heart or lung disease and diabetes requiring insulin | A single dose, not currently an annual vaccine |
| Pneumococcal (pneumonia) | All adults 50 and older who have never had it; younger adults with certain chronic conditions | Usually one dose, occasionally a series depending on which product you had before |
| Shingles (Shingrix) | All adults 50 and older, and adults 19+ with weakened immune systems | Two doses, 2 to 6 months apart |
Two of these, pneumococcal and shingles, are not seasonal at all. They land in this conversation because fall is when people think about vaccinations, which makes it the practical moment to catch up on the ones they are overdue for.
Which Ones Apply to You
If you are 50 to 64 and generally healthy: the flu vaccine annually, and the shingles series if you have not had it. The pneumococcal vaccine now begins at 50, so ask whether you are due. RSV applies only if you have a qualifying condition.
If you are 50 to 64 with a chronic condition: diabetes, heart disease, COPD, asthma, chronic kidney disease, or a weakened immune system move you into higher-risk categories for several of these. Flu and pneumococcal become more important, not less, and RSV may now apply to you at this age.
If you are 65 or older: flu annually, and specifically ask about the higher-dose or adjuvanted formulations designed for adults 65+, which produce a stronger immune response than the standard dose. Pneumococcal if you have never had it. Shingles if you have not completed the two-dose series. RSV is recommended at 75, and earlier if you have qualifying conditions. COVID benefit is greatest in this age group.
If you are pregnant, immunocompromised, or being treated for cancer: the schedule is different and some vaccines are contraindicated. That conversation belongs with your physician, not a pharmacy kiosk.
Why Chronic Conditions Change the Math
This is the part most fall vaccine coverage skips, and in the Rio Grande Valley it may be the most important part.
Influenza is not merely more unpleasant when you have diabetes, it is more dangerous. Infection drives blood sugar up and makes it harder to control at exactly the moment you are eating less and possibly vomiting. Adults with diabetes are hospitalized for flu at substantially higher rates than adults without it, and pneumonia as a complication is a common reason for admission.
The same pattern holds elsewhere. In heart disease, the inflammatory stress of a respiratory infection raises the risk of a cardiac event in the weeks after illness. In COPD, a flu or RSV infection is a leading trigger of the exacerbations that land people in the hospital. In chronic kidney disease, immune response is blunted, which makes both infection and its complications more likely. If you are managing any of these, vaccination is part of chronic disease management, not separate from it.
Hidalgo County has among the highest diabetes rates in Texas. That means a large share of adults here fall into the group for whom these vaccines do the most work, and the group most likely to assume the recommendations are meant for someone older or sicker.
What Medicare Pays
Cost is a common reason people skip vaccines they need. For Medicare patients, most of these are already covered at no cost to you.
| Vaccine | Coverage | Typical Cost to You |
|---|---|---|
| Influenza | Medicare Part B | $0 |
| Pneumococcal | Medicare Part B | $0 |
| COVID-19 | Medicare Part B | $0 |
| Shingles (Shingrix) | Medicare Part D | $0 under current law for Part D enrollees |
| RSV | Medicare Part D | $0 under current law for Part D enrollees |
The Part B and Part D split matters in one practical way: Part D vaccines run through your drug plan, so where you receive them can affect how the claim is processed. If you have Medicare and are unsure, ask before the needle goes in, a two-minute question that occasionally saves a hundred dollars.
If you are uninsured, cash prices vary widely. A seasonal flu shot commonly runs in the range of $70 to $130 at retail pharmacies in McAllen, and the shingles and RSV vaccines are considerably more. Ask about pricing before you assume you cannot afford them.
Pharmacy or Doctor's Office?
An honest answer, from a doctor's office: for a healthy adult who needs nothing but a flu shot, a pharmacy is perfectly fine. It is fast, it is convenient, and getting vaccinated somewhere beats not getting vaccinated anywhere.
The calculation changes in three situations:
You have several chronic conditions. Deciding whether you need RSV at 58 with insulin-treated diabetes is a clinical judgment, not a checkbox.
You are due for more than one. Several of these can be given at the same visit, and someone should be looking at the whole schedule rather than the one you walked in asking about.
You want it in your medical record. Pharmacy vaccinations do get reported to state registries, but records are imperfect and reconciliation is uneven. When your vaccine history lives in the same chart as your labs and your medications, your doctor can actually see what you are missing.
There is also a simple practical advantage: at a physician visit, the vaccine conversation happens alongside everything else that is due as part of your preventive care, your A1C, your blood pressure, your kidney screening, your annual wellness visit.
Where to Get Vaccinated in McAllen
Adults in McAllen have several options: retail pharmacies including CVS, Walgreens, and H-E-B; the Hidalgo County Health Department, which periodically runs seasonal vaccination clinics; urgent care centers; and primary care offices, including ours.
If you already have a primary care physician, that is usually the most efficient place to start, because the conversation covers all five vaccines instead of one.

Frequently Asked Questions
Q: I got a flu shot last year. Do I need another one?
A: Yes. Two separate reasons: the vaccine formula is updated each year to match the strains expected to circulate, and protection from any single dose fades over months. For the 2026-2027 season, all three virus components of the U.S. flu vaccine were updated compared with last season.
Q: Can the flu shot give me the flu?
A: No. The injected vaccines contain either inactivated virus or a single protein, neither can cause influenza. What some people feel for a day or two afterward is the immune system responding: a sore arm, mild fatigue, sometimes a low-grade fever. That is the vaccine working, not an infection.
Q: I am 62 with diabetes. Do I need the pneumonia vaccine?
A: Very likely yes. Pneumococcal vaccination is now recommended for all adults starting at 50 who have never received it, and diabetes independently raises the risk of pneumococcal disease. What you need depends on which pneumococcal vaccine you may have had before, which is worth checking rather than guessing.
Q: Can I get more than one vaccine at the same visit?
A: In most cases, yes. Getting the flu vaccine and another vaccine at the same visit is routine, typically in different arms. Some people prefer to space doses out to keep side effects separate, which is also reasonable. Your physician can advise based on which ones you need.
Q: Is the shingles vaccine worth it? I heard it causes a bad reaction.
A: Shingrix does cause noticeable side effects in many people, a sore arm, fatigue, headache, sometimes a day of feeling genuinely lousy, more often after the second dose. It is also highly effective at preventing shingles and postherpetic neuralgia, the nerve pain that can persist for months or years afterward. Most patients who have watched someone endure postherpetic neuralgia consider a rough day a good trade.
Q: What about the COVID vaccine this year?
A: COVID-19 vaccination recommendations have shifted toward shared decision-making between you and your physician rather than a blanket recommendation for all adults. The benefit remains clearest for adults 65 and older and for people with weakened immune systems. If you are in either group, it is worth a direct conversation.
Q: Do I need the RSV vaccine, and do I need it every year?
A: RSV vaccination is recommended for adults 75 and older, and for adults 50 to 74 with conditions that increase risk, including chronic heart or lung disease and diabetes treated with insulin. It is currently a single dose rather than an annual vaccine. If you have already had it, you do not need another this fall.
Q: ¿Ofrecen las vacunas y la orientación en español?
A: Sí. Giraldo Internal Medicine is a fully bilingual practice. Vaccine counseling, consent, and after-care instructions are all available in Spanish. Deciding which vaccines you need should not depend on how well you followed an explanation in a second language.
