Find a vet that will work with you and give the smaller pups a smaller vaccine dose. It is very important in the tiny ones to also only give one vaccine at a time. It will take longer, but there will be less chance of reaction to a single vaccine.
With the bordatella vaccine - it is either given intranasal (which is a live vaccine) or as an injection. When my Sissy got hers intranasal as a puppy, she promtly contracted kennel cough. However, when she got her booster as an injection we did not have any problems.
Keep doing your research. The more you know, the more likely your vet will work with you.
