Two-in-One Vaccine

A new, double-action vaccine that protects children against diphtheria and whooping cough at the same time was described at the Atlantic City meeting of the American Public Health Association last week. The vaccine, a combination of standard diphtheria toxoid and a new preparation containing the germs of whooping cough, was developed by Dr. Pearl Luella Kendrick of the Michigan State Department of Health.

So far, Dr. Kendrick and a group of Illinois health officials have tried the vac cine on several groups of children, whose ages ranged from six months to five years. None of them had vaccine sickness from combined doses. The diphtheria toxoid, of course, protected the children completely; the newer pertussis vaccine reduced the usual number of cases of whooping cough, moderated the disease in children who were attacked.
