Robert A. Nelson, a young (26) Johns Hopkins bacteriologist, and his co-workers have taken the first steps toward developing a more accurate test than the Wassermann.

The work opens up the possibility of vaccination against syphilis. Says Nelson cautiously: "If enough spirochetes were available, then it might be possible that they could be so treated that they could be used as a vaccine...
