Only Two vaccinations needed, they had the first with me when they had their MOT and then the 2nd one at 10 weeks then depends what vaccine your vet uses, some say OK in 48 hours others say give it 5 days and others 1 week, your vet will tell you exactly.
I would be careful, not worth taking risks of infection for the sake of a week. It's very easy for them to catch bugs and things so just be aware. These lot have had a lovely day today and are now all lying down eating their chews, all 12 dogs ( & puppies), very nice and relaxing!!! Early night for me I think the last 8 weeks have caught up with me!, that and I am getting older :-)
