It's that time of year again, when people crawl out of the woodwork shouting the failures of hundreds of years of technological advancements to the heavens. The bandwagon of mistrust in big government, big pharma, big bad doctors, and misplaced faith in big unsubstantiated opinions is about to grow three-fold like the Grinch's heart on Christmas morning. This is, after all, flu season.
The Facebook posts are running rampant: "Flu vaccine kills one boy in Texas;" "Six grandmothers in Detroit;" "Three hundred groundhogs in Montana;" "One hundred and one Arabian Nights;" and, "Twelve dancers dancing during a popular holiday sing-a-long before horrified onlookers."
Sometimes, they're framed in the form of questions designed to incite sensational reactions from the public:
"Is the flu vaccine useful?" "Does it work?" "Should we stop getting the flu shot?" "Should we stop waiting for traffic lights and wearing seat belts?" "Is eating raccoon poop really going to kill us anymore? I sprinkled some on my oatmeal this morning and I feel just fine." "Are grizzly bears suddenly the best holiday gifts for teens?"
Some of these headlines are disturbing. But make no mistake, they are all completely and unquestionably real, aside from the ones that are not.
I'm going to talk about the most common misconceptions regarding the flu vaccine, and why it's still essential that every living human do their duty to the species and get jabbed in the arm with a needle this holiday season. I will be using my unique perspective as a cancer survivor to talk about some of the immunological aspects of vaccination science. Try to relax, you may feel a little pinch.
1.) The Flu Vaccine Causes The Flu
This is completely impossible. The virus has been modified so that it's unable to proliferate and give you the flu. This is not new science, and it's been used every day for over a century. The shot form of the flu vaccine specifically doesn't even include the actual virus. It's called a subunit vaccine -- a vaccine that only contains certain parts or proteins of a virus in order to solicit an immune response to them. The nasal spray variety includes a strain of flu that's been forcibly evolved by passing it through hundreds of chick eggs in order to create a version of the disease that can't infect humans.
2.) I Always Get The Flu After Getting The Flu Vaccine
You don't (See number 1), but I can explain the reason why you might think that. Your immune system causes most symptoms you experience when you get sick -- headaches, chills, fever, nausea, aches and pains. Your body does all of that stuff to itself. A vaccine is designed to mimic a real infection, thus soliciting a real immune response. In recent years, vaccines have gotten better at diminishing side effects. Some say there shouldn't be any at all with the new rounds of flu vaccines.
Here's an anecdote. When I was going through immunotherapy, I was injecting obscene amounts of a protein called Interferon. Interferon is one of the proteins your body produces to make you feel so crappy when you get sick, and I definitely felt like I was sick all the time. That was coincidentally the year my boosters were up, and I ended up getting the flu shot, pneumonia vaccine, and the tetanus shot all at the same time. I ended up in the hospital, and after they pumped a bag of fluids into my arm, I felt a little better. Though I'm informed enough to know that the reason for this was my body's immune response to the vaccines, on top of my already overwhelmed immune system. My case was a fluke, but, subsequently, if you're currently undergoing treatment for cancer, you should consult your PCP and your oncologist to find out about side effects.
The American Cancer Society recommends that all patients get the flu shot. Read a summary of their recommendations here.
3.) Vaccines Don't Work
This is false. Edward Jenner was born in 1749. He developed an hypothesis that contracting cowpox would prevent a person from coming down with deadly smallpox. This is actually where the word vaccine originates -- from the Latin vaccinus, or, "pertaining to cows." Smallpox was eradicated from the planet in 1980. Notice how long it took to eradicate the disease from the time a solution was discovered. The reasons for this are, 1.) this was the first major step and represents the early days of vaccination science, and 2.) viruses are effing complicated. They're persistent, fast-evolving, complex organisms. Scientists have to scramble to figure out the best ways to deal with them. The flu is one of the most complicated viruses around. Seriously, look up the science, the flu is a tricky mistress. Start your research here with an article from BBC Science about the complexity of viruses and why they're so hard to beat. In the case of the flu, it's still difficult to predict which strains will run rampant each flu season with 100% accuracy, but getting the shot will offer some measure of protection regardless. And, to be fair to smallpox research, a campaign to globally eliminate the disease wasn't undertaken until 1959. If you're interested, you can read more about the history of the disease and its eradication here.
And here's a nifty bulletin from the WHO providing stats and figures for the successful use of vaccines, including the fact that in the U.S., incidence of infection from the nine diseases recommended for vaccination has decreased by 99%.
4.) Vaccines Contain Terrible, Awful, No Good, Very Bad Ingredients
The most commonly-cited ingredients of the flu vaccine are mercury and formaldehyde. Okay, let's talk a little about chemistry for a moment. Mercury is an element. It can be found in different chemicals and substances, just like any other element. The ingredient in question is called thimerosal, which breaks down into ethylmercury. Ethylmercury is a substance that metabolizes quickly and exits the body without causing a toxic build-up of mercury. Again, this is the type found in vaccines in the form of the preservative, thimerosal. The dangerous sort, methylmercury, bio-accumulates through the food chain and can build up in the body through dietary intake, and create all sorts of risk factors to an individual's health. This is why women aren't supposed to eat certain fish while pregnant -- the kind like shark and swordfish that are at the top of the food chain, because they'll have high concentrations of mercury coursing through them due to all the lower inhabitants of the food chain also consuming methylmercury. Environmental contamination of mercury is also a factor in choosing your fish. If you don't care much for facts and still like the idea of having mercury in your shot regardless, you can ask to have one without thimerosal in it.
Formaldehyde is an organic chemical that occurs naturally in the body. But, like most everything else, too much of it can be a bad thing. It's produced internally, and we ingest it daily through our diet and other means, like breathing. Formaldehyde is everywhere. Though, it also metabolizes quickly, and doesn't easily accumulate. The fact is, you get more formaldehyde by eating a pear than you do from the flu vaccine. Here's a convenient guide. Highlights to keep in mind: the most formaldehyde you'll probably get from vaccines will come when you're a baby, at the six-month checkup, and the amount will be 160 times less than the amount naturally produced by your body every single day.
There are other ingredients cited, and they all have equally reasonable and mundane chemical explanations. Why not do some reading?
5.) My Decision To Abstain From Getting Vaccinated Doesn't Hurt You
This is a reasonable thing to think. Because, what you do is your business, right? Well, not in the case of public health. It turns out, there's a thing called Community Immunity, or (an even sillier though less poetic name) Herd Immunity. Herd Immunity is a state or condition that's met when a sufficient amount of the population is immunized against a given disease, cited around 75-95%, though it varies for specific diseases. Herd Immunity provides a safety net for society, and allows us to successfully contain a virus. If you don't get vaccinated, you're running a cost-benefit analysis and playing a fun casino home-game. Only when you lose, the risks may be a little higher than you bargained for, and include the extermination of the human race. By not getting inoculated, you're providing a medium for the flu to evolve and become even harder to beat. Herd Immunity is a complex science, and you can read more about it here.
There you have it. Those are the top flu myths around, and, conveniently, my own personal favorites. There are many other false claims and misconceptions about the flu vaccine, such as, they cause autism, asthma, allergies, Alzheimer's, narcolepsy, blood disorders, the starving of puppies, your parents' divorce, and that they're descended directly from an intimate meeting between Satan and all those Hugo Weaving characters from Cloud Atlas. I won't go into these, because there is absolutely no clinical research to show that there is merit to any of them, and a whole lot of research that says they're bunk.
Parting tip: Always be wary of claims suggesting the rise in a certain disease or condition is dependent on any man-made means -- the rise of rates is proportional to the rise in population (i.e. there are more people, so there will be more cases of X). Make sure to do your own research and be your own advocate, but, at the same time, pay attention to the actual research. Facts are important.
There are other flu vaccine guides out there on the interwebs, including this one from Gizmodo, which is extremely thorough and comprehensive.
