Vaccination is an effective prevention

RICHARD House (Letters, Monday) clearly did not grow up with a friend badly disabled, and people in iron lungs, due to polio. He should be thankful that polio and smallpox are eliminated in this country and many parts of the world due to vaccination.

Conspiracy or not (and I don’t believe there is one), no-one can deny that vaccination is effective in preventing disease, and anyone is remarkably blinkered to refuse it if offered.
