August is here and it may be time for a flu shot. Public health officials say it’s not too early for protection against influenza. Two workers at a Lexington pharmacy this week erected a ‘Get your flu shot here’ sign in the parking lot. Getting a flu shot once meant an early-autumn trip to a doctor’s office or a pharmacy. But ,State Epidemiologist Craig Humbaugh says the earlier, the better. “It’s really never too early to get an annual flu shot, so we recommend that, as soon as flu shots are available and people are able to get em, this is a great time for folks to start getting their annual flu vaccination,” said Humbaugh.
