Unsure About The Flu Shot? Learn About It Alongside FM89 Reporters

Dec 4, 2018

Wherever you live in the Valley, whether it’s Hanford or Tehachapi or Merced, we all have to contend with the flu season. It’s already claimed one life in Kern County.

Last year, the CDC estimates the flu killed 80,000 Americans. That puts influenza among the top 10 deadliest conditions in the U.S, along with cancers, heart disease and diabetes. But although there’s an easy way to reduce the risk of flu—the flu shot—around 60 percent of Americans elect not to get it.

Why so much hesitation? I asked Dr. Jessica Mason, a faculty member at UCSF Fresno and an emergency physician at Community Regional Medical Center. One reason for doubt, she said, is that most of us don’t really know what the flu is. “It gets confused with the ‘stomach flu,’ which is not actually influenza at all,” she said. “Imagine the worst cold of your life, where you get horrible fevers and chills and you feel like you’re going to die.”

Unfortunately, many do. In the last five years, the flu has killed 1,100 Californians. It’s sent another 2,600 to the intensive care unit.

But a mistaken flu identity can’t be the only reason people avoid the flu shot. I set out to find a skeptic, and I didn’t have to go far: Monica Velez, a fellow reporter at FM89, says she can’t remember the last time she got a flu shot. “I wouldn’t say that I’m a denier or anything, I think I just really don't have enough information,” she said.

It’s a similar story for Laura Tsutsui, another reporter in the FM89 newsroom, who will admit to being “flu shot ambivalent.” “It was easy when I was in college when they had all these [vaccination] drives, but now that I work, it's just not a part of my routine and it's never been a habit,” she said.

But they were willing to consider it this year, so they agreed to come with me to a flu shot clinic in East Central Fresno. There, we met Leticia Berber, a friendly woman with a big, warm smile. “I'm a health educator with the Fresno County Department of Public Health, and we are here giving out free flu vaccines,” she said.

Laura and Monica came prepared with questions. Laura began, explaining that she and her siblings rarely fell ill as children, so she’s grown up believing her immune system is strong and healthy. “With that in mind, why should I still get the flu shot?” she asked Berber.

“Let's say you have your grandmother living with you, let's say you have a 5-month old nephew that cannot get vaccinated,” Berber said. By getting vaccinated, “you are protecting those individuals, not just yourself."

Herd immunity: In which enough people are vaccinated against a disease to protect the rest of the population from it.

Monica continued. “Has it been proven that this is the way to avoid getting hospitalized because you got the flu?” she asked. The answer: Yes. “The flu vaccine is the best method to protect yourself against the flu,” Berber said.

Of course, the vaccine is nowhere near perfect. Its effectiveness varies each year, reducing the risk of flu by roughly 40 to 60 percent. That may not sound like a lot, but Berber says it’s enough to protect against some strains of the flu, and make the others less severe.

“Is it a live flu that I'm about to be injected with?” asked Laura. No, Berber said. “It's just a dead virus, meaning that it will not be able to make you sick. It doesn’t have its availability to make you sick.”

Berber repeated this last point because she says falling ill due to the vaccine is the most common concern she hears—and it’s a misconception. She says: Yes, the flu shot will probably make your arm sore, and it could give you sniffles, muscle aches, and even a fever. But that’s your body’s immune system going into overdrive. It’s unpleasant, but it’s not the flu, it's not contagious, and it won't lead to any of the serious complications that could arise from the flu. “You may feel a little sick where you don't want to go to work, you want to stay in bed, and it'll go away in two to three days,” Berber said. “Flu can last up to weeks.”

Monica addressed one reason she had stayed away from the flu shot for so many years: Hearing conflicting information, including rumors that health professionals would deliberately put harmful chemicals into vaccines. “Have you heard that at all?” she asked Berber.

Of course, Berber said. “That is another myth where the vaccine contains some kind of hormone that will affect me, affect my fertility, [so that] I won’t be able to have children,” she said. “So many myths out there—we’ve heard them all.”

Then there’s the toxic metal mercury, an ingredient in a vaccine preservative known as thimerosal. Most vaccines have phased thimerosal out, but Berber said it’s still contained in some batches of the flu shot. Even then, the FDA says the amount in one dose is on par with the amount of mercury in a can of tuna (and it’s not the same form of mercury that can build up harmfully in the body). If you’re still concerned, Berber says you should be able to request a mercury-free flu shot.

Health experts also argue there’s no evidence the flu vaccine suppresses natural immunity—another very common concern—though it is an active area of research. Either way, the virus mutates over time into different strains—so even if you overcome one flu strain, and build up immunity to it, the next year’s strain will be different and you could still fall ill from it.    

By this point, Laura and Monica felt good about what they heard—good enough to get their first flu shots in years. The process was smooth and easy. They began by filling out a form with some health screener questions, like whether they’re pregnant or allergic to eggs—questions that don’t determine whether or not to get the flu shot, but which form of vaccine to get, and whether medical observation is recommended after receiving it.

Then they were ushered to a nurses’ station, where a public health nurse named Janie Rodriguez pulled each syringe out of a cooler in a sterilized, single-use package. “I'm going to wipe your arm, and I'm going to pinch your arm a little bit,” she warned, cleaning Monica’s arm with an alcohol wipe. The process was over before Monica even realized it. “Is that it? Really?” she laughed.

A small pinch to prevent a big problem.

If you’re curious about the flu shot, you can ask your county’s public health department, or look it up with the Centers for Disease Control and Prevention. You can find the flu shot at doctor’s offices and pharmacies like CVS.
