POLIOMYELITIS
For the first time in twenty years, not one case of this disease
was notified to the Public Health Department. This is no doubt due to
the general public taking advantage of the two types of vaccine now
available. It appears that oral vaccine is proving more popular and
it is hoped that the level of immunity already obtained in the Borough
will increase still further.
