Florida now leads the nation in coronavirus cases, with its biggest spike since last summer, the Tampa Bay Times reports.

Driving the surge: Hospitalizations and deaths are rising among the unvaccinated, while the small number of infected but vaccinated people are not getting seriously ill.

The big picture: Infections nationwide have tripled over the past three weeks, with about one in five new cases coming from Florida.

  • Statewide, new cases nearly doubled in the past week.
  • In Polk County, cases more than doubled from last week and hospitalizations doubled since 4th of July weekend, per the Lakeland Ledger.

Point of intrigue: Most of Florida's new cases are driven by the more infectious Delta variant, epidemiologist Dr. Vincent Hsu told WFLA.

  • Dr. David Dowdy with Johns Hopkins Hospitals drove home to. the outlet that vaccines are still effective against the Delta variant.

The bottom line: This is all proof the vaccines work.

Moderna suggests booster shots, citing clinical data

Moderna vaccine's efficacy declines a year after it's administered, compared to protection seen in recently inoculated individuals, the vaccine maker announced Wednesday.

Driving the news: Moderna made its case for supporting booster shots, citing clinical trial data that demonstrate breakthrough infections are less common among participants approximately eight months after receiving the first dose compared to approximately 13 months.

Pfizer says data suggests COVID vaccine boosters are warranted

Pfizer told the FDA Wednesday that data from its clinical trials suggests a third shot of its coronavirus vaccine may be necessary six months after the second dose because of waning efficacy.

Why it matters: The FDA's advisory committee on Friday is expected to review Pfizer's clinical trials and other supporting and conflicting data on coronavirus booster shots and make recommendations on whether more Americans 16 years and older should receive an extra dose.
