Are there better ways to protect my baby against these diseases?

No. Breastfeeding offers only temporary immunity against some minor infections like colds, but it is not an effective means of protecting a child from the specific diseases prevented by vaccines. Likewise, vitamins won’t protect against the bacteria and viruses that cause these serious diseases. Chiropractic remedies, naturopathy, and homeopathy are totally ineffective in preventing vaccine-preventable diseases.
