Many parents worry that giving several vaccines together can overload a child’s immune system. Medical evidence shows this is a myth. The immune system handles thousands of germs every day, and vaccines use only a tiny part of its capacity to build protection. Vaccines are tested for safety and effectiveness, and delaying or skipping them leaves people exposed to serious, preventable diseases. Mild effects such as fever or soreness at the injection site are common and short-lived. Follow the recommended vaccination schedule, clear your doubts with a qualified doctor, and rely on trusted medical sources rather than social media claims.
