Why Three Vaccines Matter More Than Ever
Last winter, hospitals across the country reported a “tripledemic” surge that particularly affected older adults. According to CDC data from early 2025, adults 65 and older accounted for:
- 70% of flu hospitalizations
- 60% of COVID-19 hospitalizations
- 79% of RSV hospitalizations
The risk compounds when you contract multiple viruses simultaneously or in quick succession, which can overwhelm your immune system and lead to severe complications including pneumonia, heart problems, and extended recovery times.
⚠️ Important: Having one respiratory infection can make you more vulnerable to catching another. Getting all three vaccines provides a protective shield against this dangerous domino effect.
The 2025-26 Flu Vaccine: What’s New
This Season’s Formulation
The 2025-26 flu vaccine has been updated to match the strains most likely to circulate this fall and winter. The quadrivalent vaccine protects against:
- Two influenza A strains (H1N1 and H3N2 variants)
- Two influenza B strains (Victoria and Yamagata lineages)
High-Dose Options for 65+
Seniors have three enhanced flu vaccine options that provide better protection than standard-dose vaccines:
| Vaccine Type | Key Features | Best For |
|---|---|---|
| Fluzone High-Dose | 4x the antigen of standard vaccine | Most adults 65+ |
| Fluad Adjuvanted | Contains immune booster (MF59) | Those with weaker immune response |
| Flublok Recombinant | 3x the antigen, egg-free | Those with egg allergies |
When to Get Your Flu Shot
Optimal timing: Late September through October 2025
Getting vaccinated too early (August) might mean waning immunity by late winter when flu typically peaks. However, if you haven’t gotten your flu shot by Halloween, get it as soon as possible—it’s never too late to protect yourself during flu season.
COVID-19 Fall 2025 Booster: Updated Formula
What’s in the 2025-26 COVID Vaccine
The FDA approved the updated COVID-19 vaccines in August 2025, targeting the JN.1 lineage variants that dominated last winter and spring. Both Pfizer-BioNTech and Moderna have released updated formulas specifically designed for better protection against current strains.
Who Should Get It
The CDC recommends that everyone 65 and older receive the updated 2025-26 COVID vaccine, regardless of how many previous boosters you’ve had. This is especially critical if:
- Your last COVID vaccine was more than 6 months ago
- You have chronic conditions (diabetes, heart disease, lung disease)
- You take immunosuppressive medications
- You live in a congregate setting
Timing Considerations
You should wait at least 2 months after your last COVID vaccine or infection before getting the new booster. If you recently had COVID-19, wait until you’ve recovered and completed isolation before getting vaccinated.
💡 Pro Tip: You can get your COVID booster and flu shot at the same appointment. Studies show this is safe and doesn’t reduce effectiveness of either vaccine.
RSV Vaccine: Who Needs It This Year
Understanding RSV Risk
Respiratory Syncytial Virus (RSV) isn’t just a childhood illness. Each year, RSV causes approximately:
- 60,000-160,000 hospitalizations in adults 65+
- 6,000-10,000 deaths among older adults
- Serious complications including pneumonia and exacerbation of chronic conditions
2025 RSV Vaccine Guidelines
Two RSV vaccines are available for older adults:
- Arexvy (GSK) – Single dose, approved for adults 60+
- Abrysvo (Pfizer) – Single dose, approved for adults 60+
New for 2025: One-Time Vaccine
Unlike flu and COVID vaccines, RSV vaccination is typically a one-time shot for most older adults. If you received an RSV vaccine in 2023 or 2024, you likely don’t need another one this year. Check with your healthcare provider to confirm your vaccination status.
Who Should Prioritize RSV Vaccination
The CDC recommends RSV vaccination for:
- All adults 75 and older
- Adults 60-74 with increased risk, including those with:
- Chronic lung disease (COPD, asthma)
- Chronic heart disease
- Weakened immune systems
- Diabetes
- Kidney or liver disease
- Neurologic conditions
- Living in nursing homes or long-term care facilities
Smart Timing: When to Get Each Shot
Can You Get All Three at Once?
While it’s technically safe to receive all three vaccines during the same visit, many healthcare providers recommend a staggered approach for older adults:
| Strategy | Schedule | Pros | Cons |
|---|---|---|---|
| All at Once | Single appointment | Convenient, immediate protection | More side effects possible |
| Two + One | COVID + Flu together, RSV separate | Balanced approach | Two appointments needed |
| Staggered | Each vaccine 2 weeks apart | Minimal side effects | Multiple appointments, delayed protection |
Recommended Timeline for Fall 2025
- Late September: RSV vaccine (if needed)
- Early October: Flu vaccine
- Mid-October: COVID-19 booster
This schedule ensures you’re fully protected before the holiday travel season and winter surge of respiratory illnesses.
Insurance Coverage & Cost
Medicare Coverage
All three vaccines are covered by Medicare with no out-of-pocket costs when you:
- Get them from an in-network provider or pharmacy
- Have Medicare Part B (flu) or Part D (COVID-19 and RSV)
Coverage Breakdown:
- Flu vaccine: Covered under Medicare Part B (medical insurance)
- COVID-19 vaccine: Covered under Part B through 2025, transitioning to Part D
- RSV vaccine: Covered under Medicare Part D (prescription drug coverage)
Medicare Advantage Plans
If you have a Medicare Advantage plan, all three vaccines should be covered, but check with your plan about:
- Preferred pharmacy networks for the best coverage
- Whether you need prior authorization for RSV vaccine
- Any specific providers you should use
For Those Without Part D
If you don’t have Medicare Part D, the RSV vaccine can cost $200-300 out of pocket. Consider:
- Checking if you qualify for Extra Help (Low-Income Subsidy)
- Looking into state pharmaceutical assistance programs
- Asking about patient assistance programs from vaccine manufacturers

Frequently Asked Questions
Q: I had COVID in August 2025. When should I get the new booster?
A: Wait at least 2-3 months after infection. If you had COVID in August, aim for late October or November for your booster. This timing optimizes your immune response and extends your protection through winter.
Q: Can I get vaccines if I’m on antibiotics?
A: Generally yes, unless you have a fever or are acutely ill. Mild infections being treated with antibiotics usually don’t prevent vaccination, but always inform your healthcare provider about current medications.
Q: I’m 72 and healthy. Do I really need the RSV vaccine?
A: While you’re under the universal recommendation age of 75, discuss with your doctor. Factors like frequent contact with grandchildren, travel plans, or even mild chronic conditions might make vaccination worthwhile.
Q: What if I can’t remember if I got the RSV vaccine last year?
A: Check with your pharmacy or doctor’s office—they should have records. Your Medicare Part D plan can also provide vaccination history. If no records exist and you’re unsure, consult your healthcare provider about whether to get vaccinated.
Q: Is it true that getting the flu shot can give you the flu?
A: No, this is a myth. The flu vaccine contains inactivated virus that cannot cause flu. Some people experience mild flu-like symptoms as their immune system responds, but this is actually a sign the vaccine is working.
Q: Should I get the vaccines if I’m planning surgery?
A: Ideally, get vaccinated at least 2 weeks before or after elective surgery. This ensures optimal immune response and avoids confusing vaccine side effects with surgical complications.
