People's willingness to use a Zika vaccine when it's available will be influenced by how they weigh the risks associated with the disease and the vaccine, but also by their misconceptions about other vaccines, a new study has found.
While a Zika vaccine is in development, the study by researchers at the Annenberg Public Policy Center (APPC) of the University of Pennsylvania examined factors that will affect the eventual acceptance or rejection of such a vaccine.
The study, published in the Journal of Public Health, found that people's erroneous beliefs about an association between the measles, mumps, and rubella (MMR) vaccine and autism were a predictor of people's lessened intention to get a Zika vaccine. The study also found that people's perceptions of the severity of the Zika virus as well as their general belief in the power of science to solve problems increased their intention to get the vaccine.
"When a new disease arises, people who lack understanding of the new threat may extrapolate from their knowledge of other diseases," said Yotam Ophir, a Ph.D. candidate at Penn's Annenberg School for Communication who co-authored the study with APPC Director Kathleen Hall Jamieson. "We found that the misbelief about the MMR vaccine's association with autism was more influential on the decision of whether to get vaccinated for Zika than even perceptions of Zika itself, which is worrisome, especially in light of the persistence of that misinformation."
[...] The bogus association between the MMR vaccine and autism has been disproven in numerous studies. However, the argument is still prominent among people who oppose vaccinations. "Scientists often look at the effect of misinformed beliefs about the MMR vaccine on people's intention to vaccinate children with the triple vaccine, but they don't as often look at the dangerous spillover effects that these misbeliefs can have," said Ophir, who will be joining APPC as a postdoctoral fellow.
He said that prior research has shown that it is very hard to completely debunk misinformation, such as the mistaken belief that the MMR vaccine causes autism, but the study results suggest that accurately communicating about the risks of Zika can help lessen the detrimental effects of the misbelief. "Even if we can't change what people think about the MMR vaccine, if we can give them an accurate picture of how vulnerable they are to a disease such as Zika, they can make a more informed decision about it," Ophir said.

Not to mention that the mercury issue is wildly incompatible with our understanding of how the element behaves biologically. A small, one-time dose of a biologically unavailable form of mercury is not going to cause problems in the vast majority of people. Mercury is a naturally occurring element that has been present in the environment since life first emerged from non-living precursors. Contemporary species, including humans, can easily deal with levels typical for our environment. A year's worth of tuna sandwiches doses you with more mercury than you'll experience from a lifetime of vaccines--but no one claims tuna salad causes autism.

Pretty sure injecting a years worth of tuna salad into a vein at once is going to cause some problems. Im only half kidding, your argument ignoring dose schedule and route of administration is worse than nothing.
Just talking about mercury toxicity isnt enough. Its how much entering the body in what way with what timecourse Due to the rudimentary state of medical knowledge it is dangerous to extrapolate beyond whatever precise conditions have been tested. You probably also need to take into account age, weight, diet, etc. The theory to do otherwise just isnt there.

I must also chastise you for being an armchair scientist. The arguments are as lazy as the ones anti-vaxxers bring.
