Of the 588 new patients, 197 were given a preliminary (anterior Schick)
test in order to see if they were already immune and not needing the injections ;
nine of these gave a doubtful history of having been immunised previously, and
were found negative. Of the 188, 187 re-attended for reading of the test.
Of the 187, 162, or 87 per cent., were positive; 25, or 13 per cent., were
negative.
The age distribution of the preliminary-Schick tested patients is shown
in Table 45.

immunisation.
Of these
1 had 1 injection only.
4 had 2 injections only (2 were still under treatment at the end of the
year).
157 completed the course of 3 injections.
Of the 157 who completed the course
37 were awaiting final (posterior Schick) test at the end of the year.
9 had not attended for final test.
