What vaccinations should my baby/toddler have, and when? Are these vaccines safe?

Whether vaccination is safe, there are 2 schools of thoughts: 1. Vaccine is said to cause autism, or brain damage, or multiple sclerosis, or seizures. 2. Vaccine is safe and should be used to protect from diseases. I have doubts before on this too, but I read up Dr. Sears book to understand more about vaccination. Dr. Sears mentioned vaccinations are safe as the mercury contents are below the toxic level. You can borrow the book from NLB and read up to understand more. My approach on vaccination is, I try to delay those not compulsory one e.g. Pneumococcal after my child turns older. Afterall I feel below 1 year old, babies take in so many compulsory vaccinations already. For chicken pox and Hep A I will wait till they are much older then get vaccination.
