There has been a massive amount of disinformation put about over the years (and, apparently, recently promoted by the Russian security services) regarding the effects of various vaccinations on children.
One result is that some parents are deeply wary of allowing their children to be vaccinated. Recently, the Family Court was asked to decide whether a child's routine vaccinations should continue after her parents separated: her father is deeply opposed to them. His various arguments in favour of the child not receiving further vaccinations included the claim that they would put her health at greater risk than necessary. He produced more than 300 pages of evidence in support of his arguments.
After hearing his evidence and that of an expert immunologist, the judge ruled that the child's welfare was best protected by having the vaccinations…the law requiring the Court to consider 'any harm which the child is suffering or is at risk of suffering'. In this instance, the risk to the child of not having the vaccinations was significantly greater than if she had them.
