Each year, as fall brings shorter, colder days to the Northern Hemisphere, we're reminded to get vaccinated against the flu, or influenza. In the U.S., the Centers for Disease Control and Prevention (CDC) recommends that everyone over 6 months old receive a flu shot every year.
But is there a time limit on getting your flu shot? Although it's best to get vaccinated before the season kicks off in earnest, it's still beneficial to get one toward the end of the season, two infectious-disease experts told Live Science. That advice may be even more relevant as the 2024-2025 flu season shapes up to be particularly "high-severity", according to the CDC. That's because the strains of the flu circulating this season are causing more complications and affecting young children more than usual.
