Despite there being decades of evidence that supports giving vaccines for diseases and illnesses, it hasn't stopped people shunning them out of fear it could make them worse off.
One of the biggest reasons why some people don't vaccinate their kids is the unfounded, heavily debunked theory that the MMR vaccine (for mumps, measles and rubella) can give them autism.
Well, to put one more nail in the coffin of that theory (even though there are plenty there already), a new study, involving more than 650,000 children has found that there's no link whatsoever between that vaccine and autism.
The Danish study looked at hundreds of thousands of kids born between 1997 and 2010 and the results have been published in the Annals of Internal Medicine.
This is on top of a similar study published in 2002, which involved 537,303 Danish kids born between 1991 and 1998.
And guess what that research found?
Yep - the same thing.
One of the researchers in the most recent study, Anders Hviid, said: "The idea that vaccines cause autism is still going around. And the anti-vaxx movement, if anything, has perhaps only grown stronger over the last 15 years."
The study's conclusion was similarly matter of fact.
"The study strongly supports that MMR vaccination does not increase the risk for autism, does not trigger autism in susceptible children, and is not associated with clustering of autism cases after vaccination," it said.
"It adds to previous studies through significant additional statistical power and by addressing hypotheses of susceptible subgroups and clustering of cases."
If you're banging your head against the wall saying 'WELL DUH WE ALREADY KNOW THIS', tell that to the growing anti-vaccination groups popping up all over the world.
There have been several outbreaks of measles across the US and in Japan, with more than 300 cases across the two countries recorded in this year alone.The number of global cases in 2019 has risen 30 percent.
The London School of Hygiene & Tropical Medicine's Vaccine Confidence Project found in 2018 that vaccine hesitancy had risen in places like Czech Republic, Finland, Poland, and Sweden.
But just so we're clear, this recent study and the dozens if not hundreds done before it confirm that the likelihood of your child developing autism from getting the MMR vaccine is zero.
We don't want a bunch of kids growing up and potentially infecting other kids because herd immunity has been compromised.
