MMR, and chickenpox vaccines are usually given after one year between 1 to 1 1/2 years, DPT booster is required between 15-18 months after the baby has received three doses during the first year. Hepatitis A vaccine can be given any time after one year of age. These are general guidelines and different paediatricians would use slightly different schedules which are acceptable and alright. By your description it is not very clear what is the nature of patches. MMR vaccine sometimes can give rise to red patches which are similar to measles rash which tend to settle over a period of 7-10 days. But these wont be like boils. These rashes may be unrelated to the vaccines. If the patches are not settling you should see a skin specialist for further management.
