The walls are closing in on anti-vaxxers and it's about time.
The health-based equivalent of Flat Earth theory, only less fun, has already done serious harm.
The conspiracy is playing such a significant role in America's worrying measles outbreak that at least 20 US states are proposing new laws to deal with it.
So it's always a joy to watch when someone spouting views like "vaccination is child abuse" gets shut down by irrefutable facts.
It began with some pretty wild claims:
Parents who don’t vaccinate have done the research. In reality, injecting children with toxic chemicals and heavy metals should be considered child abuse.
However, these were pretty soon set straight.
By toxic chemicals and heavy metals do you mean things like Ethylmercury, which is broken down and excreted from the body fairly quickly and which no scientific research has found links to harmful effects, including autism.
Which by the way, is not used in vaccines since 1999 with the exception of influenza.
The list continued...
Or MSG, also found only in the adenovirus and influenza vaccines, but that is also used heavily in the food industry and decades of research have shown that it is not harmful, with the exception of a minority of people that might suffer from minimal short-term reactions.
Then on to the metal whose pronunciation has been the cause of more trans-Atlantic disagreement than any president has ever been capable.
Aluminium? Which is only harmful in extremely high amounts and with dysfunctional kidneys. Which by the way, any breast-fed infant will consume about 7ml of aluminium in their diet during the first six months of their lives – and it’s also found in food, water and tonnes of other medicines we all use.
When it comes to vaccines, the amount is so small it's not even noticeable in your bloodstream.
Lastly, there was the one with - OK, we admit it - the slightly scary name.
Formaldehyde? Which is the way we make sure the viruses are actually inactive and the vaccine is clean of bacterial toxins so that people don’t get sick from them.
There is 50 to 70 times more formaldehyde present in an average newborn’s body than in a single dose of vaccine.
And a final flourish to round it off.
There is no scientific evidence showing vaccines to be harmful to the vast majority of people. And yes, some people might have different allergies or side effects but no medication is 100 percent safe and accurate. Nonetheless, the positives outweigh the negatives by very far.
Sadly no reply was shown from the author of the 'child abuse' claim, but we can thank them for prompting such a well-constructed argument.
