One of the only remaining vaccines that contains thimerosal, a mercury-containing preservative, is the flu shot. The amount may be neglible, and this is arguable when you take body weight rations into consideration, but it's important to avoid even small amounts of mercury given the fact that we have been exposed to small amounts over the course of our lives. I can't speak with authority about the rest of the country, but here in the Twin Cities my son's pediatrician only uses a thimerosal-free flu shot for children. (I should state for the record that based on overwhelming replicated scientific research, I do not believe vaccines "cause" autism. However, many people disagree with me. Regardless of your position on the issue, though, getting mercury-free vaccines is something we should all be fighting for.)
However, the adult vaccine does contain the preservative. I searched high and low in Twin Cities for a thimerosal-free shot, and learned that the only thimerosal-free offering is a nasal mist, which contains the live flu virus, albeit attenuated and highly unlikely to cause the flu. I told my husband to ask the nurses about it when he got his shot. He did. The conversation went something like this:
"Do you guys have thimerosal-free flu vaccines?"
"No."
"Really?"
"No. We don't. No one does."
"Oh."
"So which do you want, the shot or the nasal mist? The nasal mist contains the live virus. The shot doesn't."
"Oh. Well, the shot I guess."
Then, a few days ago, I finally went to see about my own flu shot. Although my toddler has been vaccinated, I didn't want to run any risk of getting him sick, nor did I want to fall helplessly ill myself because I am his primary caregiver. I walked into a SuperTarget Clinic, which have popped up in some Target stores here in Minnesota. They offer flu shots on the spot. So I walk up to the desk and after filling out paperwork, including a special survey section that determines whether I can take the live virus nasal spray vaccine--don't take if pregnant, for example--the following conversation takes place with the nurse.
"The nasal spray is thimerosal-free,right?"
[Nurse doesn't even look up from her paperwork] "No."
"I thought all nasal-spray vaccines were thimerosal-free."
"No."
"Oh."
I walk back to my seat. I begin flipping through the CDC paperwork on the vaccines she handed me as a matter of course. Under Live IntraNasal Flu Vaccine, it says in bold print: "Thimerosal-Free." I show this to the nurse. She acts surprised, takes it back to a doctor for confirmation, and then I go get my flu mist. As she's preparing the mist, she tells me it's confusing, that this is a new offering, etc., etc. She then looks at my son, who is sitting in a chair in the exam room and says: "Okay, but this contains the live virus, so if you get sick, he's going to get really,
really sick."
Aside from the fact that my son has already been vaccinated, the nasal spray is no more likely to cause the flu than the shot is. This is blatantly false, and a way to scare people out of getting this safer vaccine. But beyond that, I was appalled not only by the complete lack of knowledge on the part of medical professionals regarding the nasal spray--this wonderful thimerosal-free offering--but I was shocked by the blithe disregard of questions about it, the automatic "no."
If any of you are still waiting on your flu shot or are on the fence about it, please look into the nasal mist vaccine. And if you happen upon a clinic that offers both the shot and the spray, know that the spray is thimersol-free. Press the issue. Look at the paperwork. Challenge these receptionists and nurses. Many if them clearly have not gotten the memo. And the more demand for this spray, the more likely it will be widely available each flu season. Also, this thimerosal-free vaccine is available for children 24 months and older, so for people who live in areas or go to pediatricians who don't offer a thimerosal-free shot, this would be an excellent option.

Information from the CDC regarding flu shot and nasal mist vaccines
FluMist website (the commercial name of the spray): there is also a great location-finder that let's you identify clinics or providers within your zip code and beyond who are offering FluMist. I did notice the list was not complete--it didn't list Target Clinics for example. But it's a good starting place.
Just a quick aside. Writer Nancy Hokkanen drew my attention to the battle in Minnesota between people who want informed consent paperwork for mercury-containing vaccines and a patient right to have a vaccine with the lowest amount of mercury possible if such a choice is available and the Minnesota Department of Health. Apparently, the MDH believes that disclosing the fact that a vaccine contains mercury will dissuade parents from having their children vaccinated. I'm sure it would. But it would be an epidemiological disaster if people stopped vaccinating their children. There has to be a middle ground--and ironically, in this case, I think the "middle ground" is legislating mercury right out of all vaccines. Patients should have a right to know what is in the shots they are receiving, children deserve to be protected from vicious diseases, and I think it should be our right as human beings to have vaccines that do not contain mercury. It's possible. The CDC needs to step up and make it happen and stop making excuses like AstraZeneca (manufacturer of FluMist) won't make enough product. We hear from the company that they end up with so many unsold doses at the end of flu season that they have to destroy them.
Whew. Off my soapbox. For now.
