In May of 2015, two babies died and thirty-one were sickened after receiving vaccines for tuberculosis, hepatitis B, and rotavirus in the tiny Mexican village of La Pimienta. Four remain in serious condition. Tragedies like these are unnerving and devastating. The three viruses were spreading through impoverished rural villages like wildfire, and of course parents were willing to do anything and everything to prevent their children from being victims. How horrible, to think that something that was supposed to save lives ended up claiming them.
The most chilling reality of this situation is that the people who were most vocally upset by these deaths-- wealthy anti-vaccine activists in the United States, where deaths from tuberculosis and rotavirus are rare-- are actually the exact same people who were responsible for their deaths to begin with.
On May 12, Mexican authorities revealed that the babies sickened by the vaccine trio suffered from bacterial infections caused by contamination. Bacteria present in the multi-dose vials caused localized infections that, in some cases, led to sepsis and death. Although Mexico hasn't revealed the exact nature of the contaminants, or whether they were present during manufacturing or seeped into the vials later, the fact remains: these babies would most likely still be alive and healthy if it weren't for the anti-vaccine movement.
You see, science and history had already warned us that this is a risk of vaccination. Just as foods can get contaminated, so can vaccines. In the U.S. alone, 48 million are sickened, 128,000 are hospitalized, and 3,000 die every single year from contaminated foods. And in 1928, a horrible tragedy occurred when a group of youngsters were immunized for diphtheria, a disease with a 1 in 5 death rate for kids in the dark world before vaccines. Forty-two received shots from one vial, and of these unfortunate children, twelve died. Their cause of death was determined to be a staph infection acquired from the contaminated vaccine.
But there was a solution. We didn't have to abandon these life-saving immunizations because of a contaminant. In 1968, the U.S. Code for Federal Regulations mandated that all vaccines in multi-dose vials contain preservatives to prevent the growth of mold and bacteria.
One specific compound seemed like the best option. Thimerosal, which had been introduced forty years prior, had a long-standing history of safe and effective use as a preservative. Unlike antibiotic preservatives, it was hypoallergic. It was also affordable and extremely effective, killing a massive variety of bacteria and fungi that might otherwise contaminate vaccines. Even better, it didn't weaken the effectiveness of the vaccines themselves, as many preservatives do. And it was safe. Animal tests and clinical trials showed that, in the amounts used in medicine, it was nontoxic: when injected into both humans and animals, the worst reaction recorded was localized swelling.
Thimerosal is about 50% mercury by weight, which, at first glance, might sound terrifying. But consider, also, that table salt is made of sodium combined with chlorine, which by itself would be acutely toxic. A compound can contain a poisonous element and yet, itself, be safe. When metabolized by the body, thimerosal turns into thiosaicylate (which is harmless, despite the scary-sounding name) and ethylmercury, which an organic mercury compound considered safe.
Wakefield was a doctor-- keyword here being "was," since he is no longer a licensed medical professional-- who was trying to patent three separate vaccines for measles, mumps, and rubella, which had historically been combined into one safe and effective vaccine. He published a sketchy study in 1998 suggesting that the combination of the three vaccines, when given at once, somehow triggered a chain reaction of bowel disease that led to developmental regression in the form of autism.
Wakefield's study was fraudulent. To date, there have been 107 studies involving millions upon millions of children, finding absolutely no link between the MMR vaccine and autism. But that didn't stop Wakefield's study from having an effect. Parents, panicked by mis-reporting in the media and an apparent autism epidemic, began refusing vaccines. Specifically, they refused vaccines that contained life-saving thimerosal preservatives, mistaking thimerosal for neurotoxic mercury compounds and incorrectly blaming it for autism.
Today, no routinely recommended vaccines for children under six years of age contain thimerosal, with the exception of the live flu vaccine. That did absolutely nothing to slow the tide of vaccine refusal or the increasing rates of diagnosed autism. Rates of autism increased after thimerosal was removed from vaccines... and so did rates of vaccine contamination.
Without thimerosal as a preservative, vaccines given in multi-dose vials run the risk of contamination. And, unfortunately, there is no cost-effective way to immunize children in poor, rural regions without using multi-dose vials. Yet, because of one doctor's elaborate case of fraud, and because of the panic of his anti-vaccine followers, it is no longer included in the vaccines that need it most. Children have died as a result.
The Mexican "vaccine deaths" have been the target of mass fury from the anti-vax crowd. Some conspiracy theorists have gone so far as to speculate that the inoculations were given as part of a "depopulation" effort to reduce the number of children living in Mexico. Others have claimed media cover-up (despite wide reporting by all facets of international media). Others have attacked vaccine activists such as myself, asking if we've changed our minds now that there's an obvious case of children dying from vaccines.
I haven't changed my mind. Vaccines save lives. And the blood of those children isn't on my hands. It's on theirs.

Ethylmercury is completely separate from, and far safer than, methylmercury, which is a neurotoxic compound with a similar-sounding name. Methylmercury, the "bad" kind of mercury, is found in things we're exposed to every day, including seafood and light bulbs, yet we survive this exposure with few ill effects. Its far safer counterpart, ethylmercury, can be consumed and injected in quantities much larger without any problems. In fact, science showed again and again that thimerosal-- and the compounds it breaks down into-- doesn't harm humans at any stage in development. Even fetuses, who can suffer brain damage from Mom eating too much tuna, can be exposed to thimerosal without any problem.
For decades, thimerosal saved lives. It allowed children to be given vaccines in multi-dose vials, making them affordable even to the poorest people in the poorest regions, without the risk of contamination. The human life expectancy in countries with high vaccination rates increased by nearly 50% in just a few short decades.
Then came Andrew Wakefield.
