“The only thing we know for certain, besides [the] unpredictability [of the flu], is that getting vaccinated is the best way to protect yourself,” he said. “We’re at a very similar level of vaccination to last year. We did not see shortages of vaccine last year. We’re not hearing about shortages this year.”
Frieden added that this year’s strains look to be a great match with this year’s vaccine, of which 123 million doses have been sent out to providers.
