Are They Combining The Flu And COVID Shot? | One Visit Plan

A single combo shot is in late-stage testing, while clinics today usually give two separate injections during the same appointment.

You’ve probably noticed the shift at pharmacies and clinics each fall: a flu shot sign, a COVID shot sign, and a “want both today?” question at the counter. That pairing sparks a fair question—are these getting merged into one shot, or is it just two shots handed out together?

Here’s the clean answer: right now, most people who get both vaccines receive two separate products in one visit. At the same time, drugmakers are working on true combo vaccines that put influenza and COVID protection into a single syringe. Some are already in Phase 3 data territory, which is why you keep hearing about it.

This article breaks down what “combined” can mean in real life, what you can do this season, and what a true flu-COVID combo shot would change when it finally lands.

What “Combined” Means In Real Life

People say “combined” in two different ways, and the mix-up causes most of the confusion.

Same-Day Vaccination

This is the common setup today: you get a flu vaccine and a COVID vaccine during the same appointment, often in opposite arms. The products stay separate. The visit is combined, not the shot.

The CDC says people can get a flu vaccine and a COVID-19 vaccine at the same visit when they’re eligible and the timing lines up. The CDC also notes there’s no recommended waiting time between them. CDC guidance on flu vaccine coadministration lays out the basics, plus side-effect patterns seen in studies.

One Syringe Combination Vaccine

This is what many people picture: one injection that contains components aimed at influenza strains and the current COVID variant family. It would turn “two separate shots, one visit” into “one shot, one visit.”

These combo products exist as candidates in clinical trials and published research. They’re not the standard option at your local clinic yet.

Are They Combining The Flu And COVID Shot?

In day-to-day practice today, “combining” usually means coadministration—two separate injections at one appointment. In product-development terms, “combining” means a single vaccine candidate built to target both illnesses in one dose.

So the answer depends on which meaning you’re asking about:

• At the appointment level: Yes, many people get both in one visit, based on eligibility and timing.
• As one finished product: Not as a routine, widely available option yet. Several candidates are advancing through trials and regulatory steps.

Why Clinics Push One-Visit Timing

Convenience is the simple reason. Two separate visits are easy to postpone, then easy to skip. One appointment cuts that friction.

There’s also a seasonal reality: flu rises in colder months, and COVID keeps circulating with waves that often overlap respiratory season. A single trip to get up to date can reduce “I’ll do it later” gaps.

If you feel wary about getting two shots at once, you’re not alone. The CDC’s summary of available data says side effects like fatigue, headache, and muscle aches can show up a bit more often when vaccines are given the same day, and those reactions tend to be mild and short-lived. The same CDC page breaks down what’s known from studies. CDC’s flu and COVID shot same-visit page is the clearest single reference for that point.

What A True Combo Shot Would Change

A one-syringe flu-COVID vaccine would change the logistics more than the goal. The goal stays the same: reduce severe disease and keep you out of the hospital. The shift is about simplifying the process.

Fewer Needles, Less Paperwork

One injection can mean one product selection, one prep process, one record entry, and one injection site. That’s attractive for clinics that handle high volume in fall.

One Decision Point

Many people get the flu shot yearly and treat the COVID shot as optional or occasional. A combo product turns it into a single yes/no moment. That might raise uptake for some people and lower it for others, depending on how they feel about each vaccine.

Strain Updates Still Matter

Flu vaccines get updated each year to match predicted strains. COVID vaccines have also moved into updated formulas tied to circulating lineages. A combo shot still has to keep up with both targets, which adds complexity.

On the COVID side, the FDA has published detailed guidance on which strains manufacturers should target for seasonal formulas, tied to advisory committee review. FDA’s 2025–2026 COVID-19 vaccine formula page shows how strain selection is handled for a given season.

How Safety And Side Effects Usually Play Out

If you get both vaccines in one visit, you can expect the usual “arm and energy” pattern: sore arm, low-grade achiness, tiredness, maybe a mild headache. Many people feel normal the next day. Some feel off for a day or two, then it passes.

A practical trick: use two arms if you can. That can make it easier to tell which shot caused a sore spot, and it may keep one arm from feeling too beat up.

If you’ve had strong reactions before, scheduling the appointment when you can take it easy the next day can make the experience feel smoother.

Who Might Want To Time Both Shots Closer Together

Some groups get more benefit from staying current because their risk of severe disease is higher. Many clinics will mention these categories first:

• Adults 65 and older
• People with chronic heart or lung conditions
• People with immune suppression from meds or illness
• Pregnant people
• People who live with or care for someone at higher risk

This doesn’t mean other people shouldn’t vaccinate. It’s just how many clinics prioritize reminders when supply and appointment slots tighten.

What To Expect At The Appointment

If you’ve never done both in one visit, the flow is usually simple:

1. Screening questions: allergies, past reactions, current illness, recent vaccines.
2. Product choice: standard flu vs age-based flu options, then the seasonal COVID formula offered at that location.
3. Injection sites: often one shot in each deltoid. Some clinics will place both in the same arm if needed, spaced apart.
4. Short wait: a brief observation window, common at pharmacies.
5. Record update: confirmation card, portal entry, or state registry entry.

If you want the official “same visit is fine” wording for COVID vaccines given with other vaccines, the CDC states that children, teens, and adults may get a COVID-19 vaccine and other vaccines, including flu, at the same time. CDC’s getting your COVID-19 vaccine page includes that statement under appointment expectations.

Also, if you’re curious about injection-site details when more than one vaccine is given in a visit, the CDC has a clinician-facing page that explains general coadministration and site selection practices. CDC vaccine administration guidance covers the basic approach.

Note: If you already got one of the shots earlier in the season, you can still get the other later. You’re not locked into doing them together.

Planning Checklist For A Smooth One-Visit Appointment

Use this as a quick mental run-through before you book:

• Pick a day when the next 24 hours are flexible.
• Hydrate and eat something beforehand.
• Wear sleeves that roll up easily.
• Bring your vaccine record or know where your clinic keeps it.
• Plan light movement later (a walk, gentle arm use) to reduce stiffness.

None of this is magic. It just makes the day feel less annoying.

Common Myths That Keep Circulating

“Two Shots Means Twice The Dose”

These are two separate vaccines with their own formulations. Getting them on the same day doesn’t turn them into one mega-dose.

“If They’re Working On A Combo, Clinics Must Already Have It”

Trial-stage products can be years ahead of wide clinic availability. You can hear “Phase 3 data” long before you see a box on a pharmacy shelf.

“You Must Space Them Out”

The CDC’s flu vaccine coadministration guidance states there’s no recommended waiting time between a flu vaccine and a COVID-19 vaccine. That’s the current public guidance for eligible people. CDC coadministration guidance spells it out.

Decision Point	What Most Clinics Do	What You Can Do
Eligibility Check	Confirm age, prior doses, and timing	Bring your vaccine record or portal screenshot
Same-Day Option	Offer both shots in one appointment	Ask for one in each arm if you prefer
Shot Spacing	No waiting period required between them	Schedule together or split visits based on your calendar
Side Effects	Mild arm soreness and short-lived fatigue are common	Plan a lighter next day and keep moving gently
Product Selection	Flu options vary by age; COVID follows seasonal formula supply	Ask what brands and age-based flu options they carry
Injection Site	Deltoid in each arm is common	Tell them if one arm is injured or sensitive
Documentation	Record in clinic system and often a registry	Save your visit summary and card photo
Timing In Season	Encourage early fall, then continue through winter	Book when you’re due, even if it’s later in the season

Where Combo Vaccines Stand Right Now

Combo flu-COVID vaccines are real in the sense that they have trial registration numbers, published data, and corporate programs attached to them. They’re not yet “routine clinic stock” in most places.

What The Published Data Says

A peer-reviewed study indexed on PubMed reported that Moderna’s investigational mRNA-1083 met noninferiority criteria and produced strong immune responses against influenza strains and SARS-CoV-2, with an acceptable safety profile in studied age groups. PubMed record for the mRNA-1083 flu-COVID combo study summarizes the findings and lists the trial identifier.

What Major Manufacturers Have Said Publicly

Pfizer and BioNTech have also published updates on a combined influenza and COVID-19 mRNA vaccine program, including Phase 3 trial topline results and study details. Pfizer’s press release on its flu-COVID combination program is a primary-source summary of that work.

These updates help explain why the combo idea keeps resurfacing in news headlines each year: the science and logistics are moving, even if your local clinic still uses two separate shots.

Table 2: Flu-COVID Combination Vaccine Pipeline Snapshot

Program	Stage (Publicly Reported)	What It Targets
Moderna mRNA-1083	Phase 3 data published and discussed publicly	Influenza strains + SARS-CoV-2
Pfizer/BioNTech combo candidate	Phase 3 topline update released	Influenza + COVID-19 in one candidate
Seasonal COVID strain selection	Ongoing annual advisory and formula guidance	Updated COVID lineage match for each season
Same-visit vaccination practice	In use now in many clinics	Two separate vaccines given during one appointment

Practical Takeaways For This Season

If your goal is to be covered for both viruses this season, you don’t need to wait for a combo product. You can get the flu shot and the COVID shot during the same appointment if you’re due for both. The CDC’s public pages state this plainly. CDC flu vaccine coadministration guidance is the cleanest one-stop reference.

If you prefer to split visits, that’s also fine. You’ll still get protection as long as you complete both vaccines on a schedule that fits the season and your eligibility.

If you’re trying to predict when a true single-shot option shows up at your pharmacy, watch for two signals: (1) published Phase 3 results in peer-reviewed sources, and (2) clear regulatory announcements tied to a labeled product. Trial updates alone don’t guarantee a rollout date.

Until that day comes, “combined” usually means “two shots, one visit.” It’s simple, it’s common, and it’s already part of routine care for many people each fall.
