The holidays are just around the corner, and you know what that means — it’s time to get your flu vaccine!

You probably thought we were going to say holiday parties and presents, but that’s the thing about the flu. It can germ its way into your festive spirit and ruin all your plans with fever, headache, chills, body aches and joint pain.

“The influenza virus is nasty,” said Ilan Shapiro, M.D., senior vice president and chief health correspondent and medical affairs officer for AltaMed Health. “And what do I mean by nasty? Compared to other viruses that cause a little runny nose and cough, it’s one full week off of work or school or anything that we enjoy doing — it’s not a regular virus.”

The flu can even be life-threatening. Last year, 28,000 people in the U.S. died from flu-related illnesses and the rate of flu-associated hospitalizations was the highest it’s been since 2010.

Shapiro noted that last year’s virus stuck around for a long time, so getting the vaccine as early as you can (ideally in October) will help protect yourself from serious illness throughout the flu season.

“If we want to have a beautiful Thanksgiving, if we want to enjoy our Christmas dinner and we want to sing along with family on New Year’s, there are opportunities here to make sure that our immune system is ready for that,” Shapiro said.

The vaccine takes about two weeks for your immune system to build up antibodies to protect against the virus.

Most people associate the flu vaccine with a shot in the arm, but there is a nasal spray option for people 2 to 49 years old. Note: The nasal spray is not recommended for people with certain chronic diseases or people who are pregnant. Of course, talk to your healthcare provider (HCP) if you’re interested in the nasal spray flu vaccine.

In addition to your health, here are Shapiro’s top reasons for getting the flu vaccine this year:

1. You want to spend time with your loved ones — not with your bed. On average, most people are sick with the virus for five days. But symptoms like coughing and fatigue may go on for weeks. And while a little bed rotting can be fun, fever and FOMO are not.

2. You want your family to be well — not sick at home. Getting the flu vaccine and making sure your family gets the flu vaccine means greater protection against the virus, and less chance for serious flu-related complications. It also means you’re not at home taking care of sick people while everyone else is out decking the halls without you.

3. You don’t want to miss work. The flu is no tropical vacation. And if you have the virus, or think you have the virus, the CDC recommends staying home for at least five days after symptoms start — even if you don’t have a fever.
