It is true that natural infection almost always causes better immunity than vaccination. In fact, only the Hib and tetanus vaccines are better at inducing immunity than natural infection.
Natural infection causes immunity after just one infection, but vaccines usually create immunity only after several doses over a period of time.

For example, DTaP, hepatitis B, and polio vaccines are each recommended at least three times during the first six months of life.
The difference lies in the price paid for immunity.
The price paid for vaccination is the inconvenience of several shots and an occasional sore injection site.
The price paid for a single natural infection may be paralysis from natural polio infection, mental retardation or hearing difficulties from natural Hib infection, liver failure or death from natural hepatitis B infection, deafness from natural mumps infection, or pneumonia from natural varicella infection.
Which price do you want your child to pay for immunity?
