Flu season in New Jersey typically runs from October through April, with peak activity in December and February. The CDC recommends annual flu vaccination for everyone 6 months and older, with rare exceptions. Sage Urgent Care offers walk-in flu shots seven days a week — no appointment, no waiting weeks for your primary care office.
We carry the standard quadrivalent flu vaccine for most patients and a high-dose version recommended for adults 65 and older.
Why get vaccinated
- Reduces your risk of flu illness by 40–60% in years when the vaccine is well-matched.
- Reduces severity if you do get the flu — fewer hospitalizations, shorter recovery.
- Protects people around you, especially infants under 6 months (who can't be vaccinated), pregnant family members, and older adults.
- Required by some employers, schools, and college campuses.
When to get your flu shot
The best time is September or October, before flu activity ramps up. The vaccine takes about two weeks to reach full effectiveness. But getting vaccinated later in the season (November, December, even January) is still worthwhile — flu activity often peaks in February.
What to expect at your visit
- Quick check-in (under 5 minutes).
- Brief health screening — current symptoms, allergies, previous reactions.
- The shot itself takes seconds.
- 15-minute observation period (standard precaution).
- Out the door.
For most adults, total time at the clinic is 15–25 minutes.

Flu Shot FAQs
No. The injectable flu vaccine contains either inactivated virus or no virus at all (recombinant version) — it cannot cause flu illness. Some people feel a bit run-down for a day after the shot; that's a normal immune response, not the flu.
September or early October is ideal, before flu starts spreading. But anytime during flu season is better than not getting vaccinated.
Most patients get the standard quadrivalent inactivated influenza vaccine, which protects against four strains. Adults 65+ are typically given the high-dose version, which produces a stronger immune response in older adults.
One season — about 6 months. Flu strains change year to year, so you need a new vaccine annually.
