case of revaccination it was 71.89 as compared with 73.38 and 70.78 in the

Special Staff—Total operations.—
Statement No. I, and Appendix to
statement No. I.
12. The total number of operations performed by the Special Staff during
the triennial period amounted to 146,729 of which
90,254 were primary and 56,475 revaccination
compared with 166,390, namely 80,619 primary
and 85,771 revaccination during the preceding period, showing an increase
of 9,635 in primary and a decrease of 29,296 in revaccination. During
1914-15 the total number of vaccination operations performed by the Special
Staff was 47,066, of which 23,328 were primary and 23,738 revaccination : the
corresponding figures for 1915-16 were 47,003, total operations, 28,733 primary
and 18,270 revaccination and for 1916-17, 52,660, i.e., 38,193 primary and 14,467
revaccination. The increase in primary operations performed by the Special
Staff during the triennium under review is attributable to the deputation of
individual vaccinators to work in the plains, where the number of infants
available for vaccination is larger than in the Simla Hill States, in place of
men from the District Staff undergoing training at the Punjab Vaccine Institute.
As to the decrease in revaccination the Deputy Sanitary Commissioner reports
that the Special Staff had been in the habit of revaccinating children within
seven years of the first or primary operation in order to make up for the dearth
of young infants, especially in the Simla Hill States where people do not
generally bring up their children for vaccination under two or three years of age.
During his tour of inspection in that part of the country he devoted personal
attention to seeing that in future only the children who had faint or no marks,
were revaccinated within seven years of age.
