To feel odd about giving DS this vaccination?

[tryingtobemarypoppins2]

DS2 is 10 months. DS1 was vaccinated against Chicken pox at 12 months and I am taking him on Friday for his booster as he is now 3. Fine so far.

We are in the UK and getting this done as a private perscription via local GP's.

Anyway the GP said he would be happy to vaccinate DS2 at the same time as 10 months was not a problem as long as he has his booster later on.

I just have an odd feeling about it. I have read up on the vaccine at length but all that I have read says from 12 months. I am sure GP is right and its fine.....something just feels odd about it though......even more so when your paying for it if you know what I mean? AIBU?

My US SIL was horrified when my DS got this aged 5 and could not understand why he had not been vaccinated. TBH was no biggie for him- mild symptoms of a cold and about 80 spots (yes we counted them!) But- I never had it as a child and two weeks later ..... well I have never felt so ill in all my life. Was floored, utterly. Thank god for DH, MIL and my Mum because I was wrecked - Horrible. If I had even realised a vaccine existed we would have had it. If it's not effective before 12 months (as the evidence suggests) I would leave it until then.
