and increases steadily until full protection is reached. Children are
Schick-tested three months after immunisation in order to ensure that
the treatment has been successful.
In February, 1938, leaflets were distributed among the children
attending the Tottenham Infants' Schools, and, as a result, a large
number of requests for immunisation were received, and it was found
necessary to arrange additional sessions to cope with the response.
When, in November 1938, the use of Toxoid-Antitoxin Floccules
was abandoned in favour of Diphtheria Toxoid (Alum Precipitated), a
leaflet describing the modified treatment was circulated to the parents
of every child attending the Infants' and Junior Departments of the
Tottenham Schools and over 2,000 requests for immunisation were received
as a result.
In addition, posters have been exhibited drawing the attention of
the public to the dangers of diphtheria and urging parents to have thenchildren
immunised, and Health Visitors have given numerous talks to
mothers on this subject.
