As of January 1st all children aged 1-6 will now be offered MMRV. We can only use MMR for children aged 6 and over, and adults.
We order our vaccines weekly and always hold stock of MMR and now MMRV, but cannot give MMR to the 1-6 year olds as it isn’t now part of the childhood schedule. We work to strict guidance and protocol and our authorisation to vaccinate doesn’t allow us to give parents a choice between MMR, and MMRV.
The consensus amongst those of us actually delivering the childhood schedule is that this may potentially lead to a drop in measles protection as parents decline MMRV for spurious reasons or due to a lack of understanding, as already demonstrated online. Yes the MMRV has a slightly higher risk of febrile convulsion post-vaccine but it’s much less than the risk of febrile convulsion post natural disease -
Following the first dose of the MMRV vaccine, there is a slightly higher risk of having a febrile convulsion (35 in 100,000), than there is with the first dose of the MMR vaccine (24 in 100,000). However, the chance of a febrile convulsion is much higher if the child is unvaccinated and catches measles (2,300 in 100,000).
Febrile convulsions, whilst looking terrifying, are not harmful, are not linked to epilepsy, and can be short lived, usually lasting less than a minute or two.
I’ve been giving childhood vaccines for 26 years and anecdotally I have never seen a case of vaccine damage or (luckily ) had to deal with any serious reactions post-immunisation. Vaccines now are very different to what they were 30+ years ago so parents shouldn’t compare their own experience to their child’s.
It does make me sad to read about HCPs that aren’t open to discussion with parents though, and willing to have a sensible reasoned discussion about parental fears and concerns.
