COVID and Flu Booster Timing for Adults and Kids

As we move through 2025, questions around how frequently individuals and families should receive COVID-19 and flu booster shots are more relevant than ever. With new SARS-CoV-2 variants still circulating and flu season remaining an annual concern, understanding vaccine schedules is vital for maintaining your health and that of your children.

The Centers for Disease Control and Prevention (CDC) has updated its guidelines based on current data, virus trends, and population immunity levels. Here’s what you need to know.

Rapid tests remain a vital tool in the medicine cabinet for ongoing infection cycles of COVID-19. Be sure to stay stocked up with market-leading ASSURE-100 rapid tests this season.

How Often Should Adults Get a COVID-19 Booster?

The CDC recommends that all individuals aged six months and older receive the 2024–2025 COVID-19 vaccine. This updated formulation targets the most prevalent SARS-CoV-2 variants, including the XEC lineage and other Omicron descendants.

Adults 18 to 64 Years Old

Annual Booster: Most healthy adults are recommended to get one COVID-19 booster shot annually, typically in the fall or early winter.
Increased Risk Settings: Adults working in healthcare, education, or public-facing jobs should consider annual boosters as non-negotiable.

Adults 65 and Older

Biannual Booster: Adults aged 65+ are advised to receive two doses of the updated 2024–2025 COVID-19 vaccine, spaced at least six months apart.
Why Two Doses? Older adults tend to have a weaker immune response and are at higher risk for hospitalization and death from COVID-19. The second booster helps sustain immunity through seasonal surges.

Immunocompromised Adults

Customized Schedule: Individuals with moderate to severe immunocompromising conditions may require multiple doses. Consult your healthcare provider for personalized guidance.

How Often Should Kids Get a COVID-19 Booster?

Children, like adults, are recommended to receive the 2024–2025 COVID-19 vaccine.

Children Aged 6 Months to 17 Years

Annual Booster: One dose annually is recommended for most children to maintain protection against circulating SARS-CoV-2 variants.
Multiple Doses for Some: Children who are moderately or severely immunocompromised may need additional doses, subject to pediatric guidance.
Why Kids Still Need Boosters

While children typically experience milder illness from COVID-19, some develop serious complications such as MIS-C (Multisystem Inflammatory Syndrome in Children) or long COVID. Boosters help protect kids and reduce virus spread in schools and homes.

When Should I Get My Flu Shot?

The CDC recommends an annual flu shot for everyone aged six months and older, typically administered between September and October before the flu season peaks.

Flu Booster Considerations

Kids Under 9 Getting Their First Flu Shot: Children between 6 months and 8 years who are getting vaccinated for the first time need two doses, spaced at least four weeks apart.
High-Risk Groups: Older adults, people with chronic illnesses, and pregnant women should prioritize annual flu vaccines to prevent severe complications.

COVID-19 and Flu: Can You Get Both Shots at Once?

Yes, the CDC confirms it’s safe to receive both the flu vaccine and the COVID-19 booster during the same visit. Doing so simplifies the immunization process and ensures timely protection.

Monitoring Your Health with Rapid Testing

As new COVID-19 variants continue to circulate in 2025, regular monitoring through testing remains essential. Rapid testing is especially helpful if you’re symptomatic, traveling, or preparing for a family gathering. Protect your family and loved ones with ASSURE-100 family packs.

Benefits of Rapid Home Tests

Quick Results: Results in 15 minutes or less.
Home Convenience: No need to visit a clinic or wait in line.
Travel-Ready: Useful before trips or when returning from high-risk areas.
Whether you’re vaccinated or not, testing before and after potential exposure can help reduce the spread of COVID-19 in your community.

Best Practices to Stay Protected in 2025

Stay Up to Date on Vaccines: Keep track of both flu and COVID-19 booster schedules.
Use Rapid Tests: Have tests available at home to check symptoms quickly. Get rapid COVID tests on Amazon.com.
Practice Good Hygiene: Wash hands frequently, especially during flu season.
Ventilate Indoor Spaces: Keep windows open or use air purifiers in enclosed areas.
Wear Masks in High-Risk Settings: Masks remain a useful tool in hospitals, transit, or during outbreaks.

Final Thoughts

Navigating booster schedules in 2025 doesn’t have to be confusing. For most people, a yearly COVID-19 and flu shot will suffice. For older adults, immunocompromised individuals, and young children, more tailored vaccine strategies may apply. Stay informed by following CDC updates, consulting your doctor, and using rapid testing when needed.

The combination of up-to-date vaccinations, smart testing, and preventive habits can keep your family safer and healthier all year long.
