Breast Milk is the key for newborns life immune system, not vaccines.
From wikipedia...
Health authorities consider human breast milk the healthiest diet for babies, as opposed to infant formula.
[2] Breastfeeding promotes health of both mother and infant and
helps prevent disease. Infants who are not breastfed are at a significantly increased risk for a large number of acute and chronic diseases including
lower respiratory infection, ear infections, bacteremia, bacterial meningitis, botulism, urinary tract infection, and necrotizing enterocolitis.
[30] They state that there are a number of studies that show a possible protective effect of breast milk feeding against
sudden infant death syndrome, insulin-dependent diabetes mellitus, Crohn's disease, ulcerative colitis,lymphoma, allergic diseases, digestive diseases, and a possible enhancement of cognitive development.

Breastfeeding provides unsurpassed natural nutrition to the newborn and infant. Human breast milk also contains numerous protective factors against infectious disease and may influence immune system development, In addition to being the best source of nutrition for newborns and infants, human breast milk also provides immunologic protection against many infections.

Immunologic Factors in Human Breast Milk
For the fetus and newborn, immunologic defenses are present, but immature. To compensate, the mother's immunoglobulin (Ig) G antibody moves across the placental barrier to provide some protection. After birth, these maternal antibodies wane in the first 6 to 12 months of human life. The neonate and infant can receive additional maternal protection from breast milk, however.
Human breast milk contains large quantities of secretory Ig A (sIgA). These antibodies, which have formed as a consequence of the mother's previous exposure to infectious agents, can bind to potential pathogens and prevent their attachment to the infant's cells. Secretory IgA is adapted to survive in the respiratory and gastrointestinal mucosal membranes and resist proteolytic digestion. Secretory IgA neutralizes infectious agents while at the same time limiting the damaging effects of tissue inflammation that can occur with other antibody types.
Human breast milk, and especially the early colostrum, contains measurable levels of leukocytes. Colostrum contains approximately 5×106 cells per mL, an amount that decreases tenfold in mature milk. Most of these leukocytes are macrophages and neutrophils, which phagocytose microbial pathogens. Lymphocytes, including T cells, natural killer cells, and antibody-producing B cells, make up 10% of the leukocytes in human breast milk. There is evidence to suggest that these cells survive passage through the infant's gastrointestinal system where they are absorbed and influence the infant's immune response.
11 Much of this evidence comes from animal studies, however, which will be discussed later in the present review.
In addition to these immunologic components, breast milk contains several nonspecific factors that have antimicrobial effects.
12 These factors include the enzyme lysozyme, which inhibits the growth of many bacterial species by disrupting the proteoglycan layer of the bacterial cell wall. Lactoferrin, one of the most abundant proteins in human milk, also limits bacterial growth by removing essential iron. Nucleotides in human milk have been shown to enhance immune function in infants.
13 Complex sugars are found only in trace amounts in cow milk but make up a substantial portion of human milk sugars, where they may prevent adherence of various microbial pathogens by acting as decoy receptors.

Breastfeeding and Childhood Vaccination
It has also been suggested that breastfeeding influences an infant's response to common childhood vaccinations.
2,
3 Several studies have shown increased immune response to vaccines in breastfed vs formula-fed babies.
18,
19 Greenberg and colleagues
20 studied immune responses to
Haemophilus influenzae type b-tetanus toxoid conjugate vaccine in a subset of 10,000 immunized infants and
found a significant increase in antivaccine antibody in infants that had been breastfed for at least 6 months. Other studies
21,
22 have found no such positive effects, however. Still others have even found a significant adverse effect on seroconversion.
23
Studies showing no effect or adverse effects of breastfeeding in childhood vaccinations often used live viral vaccines whose immunogenicity may be inhibited by the sIgA of human breast milk.
For example, the three studies included in the meta-analysis by Pichichero,23 with approximately 500 infants in total, all examined antirotaviral responses after an oral dose of a live attenuated Rotavirus vaccine. Proper immunization with live oral virus vaccines depends upon viral replication, which could be inhibited by the sIgA of breast milk. Indeed, increasing the vaccine dose diminished the “adverse” effect of breastfeeding.
