Flu, RSV and COVID-19 in Connecticut: your fall 2026 vaccine guide

Which vaccines should I get this fall in Connecticut?

For the 2026-27 season, the CDC recommends an annual flu vaccine for everyone 6 months and older, a COVID-19 vaccine for all adults, and a one-time RSV vaccine for adults 75 and older plus some adults 50 to 74 at higher risk. Connecticut's Department of Public Health echoes those recommendations and adds specific guidance for infants and pregnant people. The short version: if you are an adult in Shelton or anywhere in New Haven or Fairfield County, this fall is the time to get your flu shot, catch up on COVID-19 vaccination, and ask your provider whether the RSV vaccine fits your health picture.

Flu: everyone 6 months and older, ideally by late October

The CDC recommends annual flu vaccination for everyone 6 months and older who has no contraindication, and any FDA-licensed, age-appropriate flu vaccine is acceptable. For most people, the ideal window is September or October, and getting vaccinated by the end of October is a good target because flu activity in Connecticut typically peaks between December and February. It is never too late: vaccination should continue while flu viruses are circulating. Adults 65 and older should preferentially receive a higher-dose, adjuvanted or recombinant vaccine rather than a standard-dose one. See the CDC's 2026-2027 flu season page and the interim clinical considerations for the full details.

RSV: a one-time vaccine for older adults

RSV is not an annual vaccine. The CDC recommends a single dose of any FDA-licensed RSV vaccine for all adults 75 and older, and for adults 50 to 74 who are at increased risk of severe RSV illness, such as those with chronic heart or lung disease, a weakened immune system, or certain other underlying conditions. The best time to vaccinate is late summer or early fall, before RSV typically starts spreading. Anyone who has already had one dose should not get another. Connecticut's DPH aligns with this guidance for older adults and high-risk groups, and separately recommends protecting infants either by vaccinating pregnant people during weeks 32 to 36 of pregnancy or by giving monoclonal antibodies to babies entering or born during RSV season. See the CDC's RSV vaccine guidance for adults for details.

COVID-19: updated guidance for the 2026-27 season

The CDC recommends the 2026-27 COVID-19 vaccine for all adults 18 and older, with emphasis on adults 65 and older, people at increased risk of severe illness, residents of long-term care facilities, and anyone who has never been vaccinated. Connecticut's DPH encourages everyone 6 months and older to talk with their healthcare provider about a COVID-19 shot, with the strongest recommendation for young children and people in high-risk groups. Dosing and scheduling depend on age and immune status, so the simplest path is to ask your primary care team what the current recommendation is for you. The CDC's routine COVID-19 vaccination guidance is the current reference.

Where to get vaccinated in Connecticut

Most Connecticut residents can get vaccinated at their regular healthcare provider or a local pharmacy. The Connecticut Department of Public Health publishes a vaccine information page with a search tool for flu, COVID-19 and RSV locations, and it runs a statewide list of influenza vaccination clinics in partnership with local health departments and community health centers. In its October 2026 respiratory season announcement, DPH emphasized October as the best month for the flu shot so protection lasts the whole season, and highlighted its "Protect Who Matters Most" campaign to help families talk with providers about vaccines.

When should I see a primary care provider instead?

Vaccines are the prevention part; primary care is where the questions get answered. A visit is worth scheduling if you are unsure which vaccines apply to you, if you have a chronic condition such as asthma, diabetes or heart disease that raises your risk, if you are due for other preventive care such as blood pressure, cholesterol or blood sugar checks, or if you have had a reaction to a vaccine before. Your primary care team can also tell you when symptoms like fever, cough or congestion deserve an office visit rather than a pharmacy run, and when they warrant urgent or emergency care.

A note on timing and the months ahead

Respiratory virus season runs from fall through early spring, and guidance can shift as new data and new vaccine formulations arrive. The recommendations above reflect the CDC and Connecticut DPH guidance in effect for the 2026-27 season. If you are unsure what applies to you, the most reliable move is a short conversation with a clinician rather than a search result. Getting your flu shot by late October, checking whether the RSV vaccine applies to you, and confirming your COVID-19 status covers most adults for the season ahead.
