Early tests showing flu vaccine good match for strains

It is officially flu season, but the CDC doesn't typically start tracking cases until later this month.

But the good news is early tests are showing this year's vaccine is a good match for the strains that could be going around.

Last year, the flu shot got a bad reputation because the predominant virus mutated and the vaccine wasn't very effective.

But even if the vaccine doesn't give you 100% protection, it can still boost your immunity and help prevent severe symptoms.

So everyone over 6-months old is urged to get vaccinated.

It takes two weeks to build immunity so it's best to get a flu shot soon.

As for the bad news, some doctors believe if you do get the flu this year, it could be a severe strain just based on what we've seen the past few years.
