There’s a common misconception that receiving multiple vaccines will “overwhelm”, “weaken”, or “use up” the immune system. In reality, alternative vaccine schedules have absolutely NO scientific basis.
Babies begin being exposed to immunological challenges at the time of birth. As babies pass through the birth canal, they are immediately colonized with trillions of bacteria, which means that they carry the bacteria in their bodies but aren’t infected by them. Healthy babies constantly make antibodies against these bacteria and viruses. The microbiome helps prime the immune system so that children can appropriately respond to pathogens (disease-causing microbes).
Eating, drinking, breathing, and playing all expose our kids to more antigens (by many orders of magnitude) than vaccines. Even if given all at once.
Extensive research shows that simultaneous vaccination with multiple vaccines has no adverse effect on the immune system. Recommended vaccines are as effective in combination as they are individually, and such combinations carry no greater risk for adverse side effects.
CDC’s recommended vaccine schedule is based on how the immune system responds to vaccines at various ages, and how likely we are to be exposed to a particular disease. This ensures your little one is protected from over a dozen potentially serious diseases at exactly the right time. The more you delay vaccines, the more time kids are vulnerable to infections from which they could be protected.
Infant immune systems are stronger than you think! Based on the number of antibodies present in the blood, a baby would theoretically have the ability to respond to around 10,000 vaccines at once. Even if all 14 scheduled vaccines were given at once, it would only use up slightly more than 0.1% of a baby's immune capacity (and this capacity is purely theoretical). The immune system could never truly be overwhelmed because the cells in the system are constantly replenished. Babies are exposed to countless bacteria and viruses every day, and immunizations are negligible in comparison. Please do NOT skip, delay, or spread out your child’s vaccines!
