Vaccines are expected to prevent issues.
One does not need vaccines for everything for which a vaccine exists. For instance, doctors in my area refuse to give Hep A, Heb B, pneumonia, and shingles to healthy adults who have no apparent risk profile. My wife has had shingles twice, and she's still to young to get the d@mn vaccine.
Why can doctors refuse vaccines to full adults, while giving everything to a baby under two months of age?
Your logic is greatly flawed.
Your wife needs another doctor!
