Hi Liz,
You may want to look up a homeopathic vet in the UK. Sue Armstrong, Chris Day, several others. Ask about getting nosodes for parvo and distemper (I think both diseases are there, yes?). You luckily live free of rabies, so you *could* simply protect with nosodes till 9 months old and let the mature immune system carry on from there for life.
Some risk of getting viruses from recently vac'd sibs, yes, but the route of exposure (oral, nasal) pretty safe compared to getting injected. No mercury, no aluminum, just some attenuated viruses that could end up building some immunity with little to no risk of illness to your pup.
