"The risks associated with the disease are minimal anyway."
The risks of the vaccine are even less!
In my own immediate environment i know
One stroke in a 6 year old caused by chicken pox, causing paralysis completely down one side, but he has recovered but obviously he lost a lot of school and has been left with some learning difficulties. He also had to learn to talk again.
one death of a perfectly healthy parent caused by chicken pox
numerous adults catching chicken pox from their child and becoming very ill (so not guaranteed to catch as a child)
One immunosuppressed child was in very close proximity to my DS the day before his spots came out, so had to be rushed to GO for the 4th time to get the special vaccination that only works for two weeks (can't remember what it is called)
then if a baby gets chicken pox it is unlikely to be immune and also more likely to get shingles as a child
I have had shingles it is very unpleasant and was still getting neuralgia over 10 years later and was left with a lump in my groin for 4 years. That was a very mild case with just 12 spots.
There is no evidence to date that lack of wild chicken pox in the environment has led to higher incidents of shingles, and shingles can now be vaccinated against as well.
