An unvaccinated child in Florida is the first person nationwide to die from the flu in the 2018-2019 season, the Florida Department of Health announced Monday.

Officials reported the child was healthy until the time of illness and tested positive for Influenza B between Sept. 30 and Oct. 6.

The state office did not share additional information about the victim or the date of death, according to a local report.

Last year's flu claimed 80,000 lives in the United States — the highest on record for one year.

One of the reasons last year's death toll was so high was due to the spread of a new flu strain, H3N2, that the 2017-2018 vaccine had not included.

Dr. Richard Webby is part of a the World Health Organization's Vaccine Composition Team, a group of scientists who recommend which flu vaccines to put into circulation every year. Webby said the flu shot has been reformulated based on last year.

“Although it’s too early in the United States to make predictions, we can look to the Southern Hemisphere, where flu season is winding down, and see the dominant circulating viruses are better matched to the vaccine," Webby, a member of St. Jude Children's Research Hospital's Infectious Diseases Department, said in a statement.

Webby said the vaccine is not perfect but is a person's best step to prevent the onset of flu, minimize symptoms if one does fall ill, and prevent the spread of illness.

Surgeon General Jerome Adams kicked off Health and Human Services #FightFlu vaccination campaign last month when received a flu shot at a press conference.
