Are immunizations 100% effective? ›

While no vaccine offers 100% protection, they are extremely effective and are our best defense against infectious diseases.

Personal beliefs: according to the study, some parents feel that there's a benefit to allowing kids to experience childhood illnesses to boost immunity. Parents may also be concerned about putting chemicals in their children's bodies and feel that vaccines are not “natural” enough.

Vaccines teach your immune system how to create antibodies that protect you from diseases. It's much safer for your immune system to learn this through vaccination than by catching the diseases and treating them.
