Jacksonville health officer underscores MMR vaccine safety, sets free clinic after confirmed Duval measles cases

Measles cases prompt expanded access to routine vaccinations

Jacksonville public health leaders have moved to broaden access to routine immunizations after measles cases were confirmed in Duval County in January 2026. City and county health officials said the response centers on helping residents verify vaccination status and obtain recommended shots, with a focus on measles, mumps and rubella (MMR) vaccination.

A free, walk-in pop-up immunization clinic is scheduled for Sunday, February 1, 2026, from 9 a.m. to 12 p.m. at the Regency Library, 9300 Regency Square Blvd. Vaccines offered at the event include MMR, influenza and hepatitis A.

Where residents can get vaccinated in Duval County

Beyond the one-day clinic, immunizations are available during regular weekday hours at Florida Department of Health service sites in Jacksonville. Officials said residents can walk in or schedule an appointment by phone.

• 515 W. 6th St., Jacksonville, FL 32206 (Monday–Friday, 8 a.m.–5 p.m.)
• 3225 University Blvd. South, Jacksonville, FL 32216 (Monday–Friday, 8 a.m.–5 p.m.)

Health officials advised residents to bring photo identification and any available immunization records to help determine what vaccines may be needed.

Why measles cases trigger rapid public health action

Measles is one of the most contagious infectious diseases and spreads through respiratory droplets and airborne particles. The virus can remain in the air for up to about two hours after an infected person leaves an area, which can create exposure risks in shared indoor spaces. Public health responses typically emphasize vaccination and prompt guidance for people who may have been exposed.

Health leaders emphasized that the MMR vaccine has a long-established safety record and remains the primary tool for preventing measles.

MMR recommendations and what families should check

The standard childhood schedule calls for two doses of measles-containing vaccine: a first dose at 12–15 months and a second dose at 4–6 years. Older children and adults who lack evidence of immunity may also need one or two doses depending on risk factors. Health officials encouraged families to review school-age children’s records and adults to confirm their own status, particularly those who work in healthcare, childcare, or other settings with close contact.

Officials said residents who believe they have been exposed or who develop symptoms consistent with measles should contact a healthcare provider before arriving for in-person evaluation, to reduce the chance of exposing others in waiting rooms and clinics.
