To the Editor:

Irving Glater ignores the facts behind measles vaccination. The death rate from measles is 3 per 1000 cases, small but very significant if one of those three happens to be your child, or grandchild.

Furthermore, herd immunity is decreased if the number of immunized people is insufficient so outbreaks are more likely to occur, increasing the risk for unimmunized individuals.

In N.H., the rate of death from motor vehicle accidents is about 5 per 100,000 people. Somehow we find it necessary to make seatbelts mandatory for a threat that is 60 times less than the threat of death from measles. Does he oppose seatbelts too?
