Maryland Flu Surge: Vaccination Rates Stall at 8 Percent

Influenza cases are climbing across the United States, with the most intense activity currently centered in the Western and Southern regions. Health experts in Maryland are preparing for a surge of patients as local data indicates the virus is actively circulating, although current case numbers remain low relative to historical averages.

The Maryland Department of Health reports that the majority of confirmed cases in the state involve H1N1 subtypes of influenza A. Andrew Pekosz, co-director of the Johns Hopkins Center of Excellence in Influenza Research and Response, noted during a media briefing on Thursday that these specific strains have a history of evading existing immune protections. Despite this challenge, he stated that the current vaccine should effectively prevent severe disease and hospitalization.

Pekosz emphasized the timing of the vaccination window, explaining that it takes approximately two weeks for the body to develop antibodies against the virus. "It’s best if [vaccinations are] taken before the influenza season starts," he said. He added that the current vaccine formulation covers three flu strains, with two appearing to be good matches for what is circulating this season.

The economic and social impact of the virus is already visible in the state’s healthcare metrics. As of the week ending Oct. 17, approximately 5,000 people nationwide were admitted to hospitals for flu-related illness, according to the U.S. Centers for Disease Control and Prevention. Dr. Anna Durbin, director of the Johns Hopkins Center for Immunization Research, described these figures as somewhat high for this early in the season.

In Maryland, the human toll includes nearly 100 hospitalizations and one death so far this season. A notable local outbreak affected 50 elementary students and staff in Prince George’s County, prompting an unusual school shutdown to contain the spread. Wastewater sampling as of Oct. 17 suggests that the number of untested, symptomatic individuals in the state remains low, indicating that the rise in cases is likely driven by recent introductions rather than a hidden wave of undetected illness.

Vaccination uptake remains a central concern for state health leaders. Current state data shows that only 8% of the population has received a flu shot. Officials have aligned their guidance with major medical associations, recommending vaccination for everyone six months and older, a stance that contrasts with the evolving and sometimes confusing messages issued by federal health officials following the disbanding of a prominent advisory panel.

Durbin advised residents to verify pharmacy inventory and insurance coverage before seeking treatment, noting that out-of-pocket costs for the vaccine can reach $100. She highlighted that a new mRNA version of the vaccine, recommended for those age 50 and older, showed higher protective efficacy in trial data compared to traditional formulations. Pekosz also urged residents to stock at-home tests for flu and COVID-19, noting that different antiviral medications are available to reduce the duration and severity of illness.

To maximize health security during the upcoming months, Pekosz recommended that eligible individuals get their COVID-19 and RSV vaccines at the same time as their flu shot. "We expect to see cases in coming weeks," he said, linking the coordinated vaccination approach to a proactive defense against the anticipated winter respiratory season.
