If it feels like COVID-19 never fully went away, you are not imagining it. As infections climb in several parts of the United States this fall, the FDA has just given the green light to four updated COVID-19 vaccines for the 2026–2027 season. Here is what changed, who the shots are for, and how to decide if one is right for you.
What Did the FDA Just Approve?
On August 27, 2026, the U.S. Food and Drug Administration approved four updated COVID-19 vaccines from three manufacturers: Moderna, Pfizer-BioNTech, and Novavax (in partnership with Sanofi). Each formula was updated to better match the strains currently circulating, with most targeting the JN.1-lineage XFG variant, which has become the dominant strain nationwide.
The approval comes as health officials track a late-summer and early-fall uptick in COVID-19 cases, particularly across the South and West. Manufacturers say doses are already shipping, with availability expected at pharmacies and clinics within days.
The Four Approved Vaccines
| Vaccine | Manufacturer | Type | Who It's Approved For |
|---|---|---|---|
| Spikevax | Moderna | mRNA (full-spike) | Ages 6 months–64 with a high-risk condition; all adults 65+ |
| mNEXSPIKE | Moderna | mRNA (partial-spike) | Ages 12–64 with a high-risk condition; all adults 65+ |
| Comirnaty | Pfizer-BioNTech | mRNA | Ages 5–64 with a high-risk condition; all adults 65+ |
| Nuvaxovid | Novavax / Sanofi | Protein-based | Ages 12–64 with a high-risk condition; all adults 65+ |
Nuvaxovid stands out as the only protein-based option among the four, which can make it a good alternative for people who prefer to avoid mRNA technology or who had a strong reaction to an mRNA dose in the past.
Why "High-Risk Conditions" Matter for Eligibility
Unlike earlier pandemic years when vaccination was recommended for nearly everyone, this season's approvals are narrower. Outside of adults 65 and older, a shot is only approved for younger people who have at least one condition that raises their risk of severe COVID-19. According to CDC guidance, that list is broad and includes:
- Asthma or chronic lung disease
- Diabetes
- Cardiovascular disease
- Overweight or obesity
- Pregnancy
- A weakened immune system
- Mood disorders such as depression
Why an Updated Formula Matters
SARS-CoV-2 keeps mutating, and older vaccine formulas gradually lose their edge against newer variants. Updating the vaccine each year is similar to how the annual flu shot is reformulated: the goal is not to prevent every infection, but to lower the odds of hospitalization and severe illness, especially for people whose immune systems are less able to fight off the virus.
When and Where to Get Vaccinated
With cases already rising in some regions, health experts generally recommend getting an updated dose in early-to-mid fall so protection is in place before winter gatherings and colder weather push respiratory illnesses higher. A few practical notes:
- Vaccines are expected to be available at major pharmacy chains and doctor's offices within days of approval.
- Because the CDC's official recommendation process has been unusually unsettled this year, some pharmacies may ask for a prescription or provider consultation before administering a dose — call ahead to check local requirements.
- If you have a chronic condition, ask your doctor whether it is safe to get a COVID-19 vaccine alongside your annual flu shot.
Possible Side Effects
Most people experience only mild, short-term effects such as soreness at the injection site, fatigue, mild fever, or headache for a day or two. Serious side effects remain rare. As always, discuss your personal health history with a healthcare provider before vaccination, especially if you have had a prior allergic reaction to a COVID-19 vaccine.
The Bottom Line
COVID-19 has not disappeared, and this season's updated vaccines are designed to keep pace with the variant currently spreading across the country. If you are 65 or older, or you live with a condition on the CDC's risk list, this is a good moment to talk to your doctor or pharmacist about whether an updated dose makes sense for you this fall.
