Re "Vaccines have negative reactions"(Letters, Sept. 29): The letter writer implies that health professionals' knowledge and advice about vaccines is worthless since they can't guarantee against a negative reaction "with 100 percent confidence."
As all doctors and most of the rest of us know, that's not how the world works.
Each of us is different, with a range of reactions to germs, medicines, bad news, you name it. What doctors can provide is informed consideration of risks. Yes, a small percentage of people may suffer discomfort or even health risks as a result of vaccines.
But think for a minute about what risks are avoided -- would you prefer to live in a world where polio is commonplace? That is the reality in parts of the world where too many agree with the letter writer.
