âVaccines help to protect not only the child being vaccinated, but also the child who is not vaccinated,â explains Dr. Widerman. âIf the vast majority of children are vaccinated, then it will be much more difficult for a disease to spread.â.accines, or immunizations, contain antigens that cause diseases; however, the antigens in vaccines are weakened or killed. Exposure to such weakened antigens stimulates the immune system to create antibodies that prevent disease.
