I wouldn’t get the vaccine because the concerns about the risk of contracting more serious cases’ of singles later haven’t been satisfied. Which is another reason the NHS don’t offer routinely
If someone never gets chicken pox, they can never get shingles. In addition, a shingles vaccine now exists for those in at-risk groups.
The theory was that chicken pox freely circulating in the population meant people got regular ‘boosters’ and were less likely to get shingles, which is particularly serious for older people.
That theory hasn’t been borne out by the evidence base we have now - particularly around risks to the elderly. The evidence now shows that there is a temporary increase in shingles cases - around double - but almost entirely in 31-40 year olds, rather than the elderly.
New papers have also found that the ‘beneficial’ effect of exposure to chicken pox as a booster to shingles immunity lasts only two years, not 20 as previously thought.
The idea that you would put children at risk of unpleasant and potentially (if unusually) serious illness to avoid an unpleasant and potentially (if unusually) serious illness among people in their 30s is pretty bizarre. It is even more bizarre when you consider the temporary nature of the increase, because once vaccinated people are in that age group, the risk disappears.
The UK is increasingly an outlier on not vaccinating against chicken pox and the reasons are more to do with Wakefield than the evidence base for vaccinating.
The other reason for vaccinating children is that it’s around 98% effective for them. Waiting until they are a teenager or adult means 75% effectiveness.
