The February, 1964, issue of Health News (a publication of the New York State Department of Health) contains an advertisement addressed to "Dear Physician" which asks the doctor to remind his patients to continue vaccination against "Diphtheria, Whooping Cough, Polio, Tetanus, and Smallpox." My question is, "What happened to measles?"
All of us cheered the announcement last year that a measles vaccine would soon be available to the public. Last autumn we contemplated a spring free of miserably sick children with cough, conjunctivitis, coryza, and rash complicated by respiratory distress or encephalitis.
