Your logic is flawed and here's why: If you agree with the CDC's admission that human breast milk is better for your baby, then you are admitting that natural nourishment is better than synthetic formula. As such, you are implicitly conceding that acquired natural immunity is better than synthesized immunity for the same principles.
It is true babies who are breastfed acquire their mother's immunity for a short period, but not surprisingly your understanding falls short there. Human breast milk's purpose is to also build a more robust platform in which the baby's own immune system can grow naturally strong and resilient. If this process succeeds and healthy lifestyle is incorporated therein, there is much less need to be vaccinated (if any need at all).
You're an antivaxer and you don't even know it! What's keeping you from coming out the closet all together? Hmmmmmmmm?
