A decrease in revaccinations was recorded in all the districts except
Sialkot, Gujranwala, Gujrat, Rawalpindi, Montgomery, Lyallpur, Jhang and
Multan and was most marked in Amritsar (31820), Dera Ghazi Khan (30196),
Muzaffargarh (25092), Karnal (21784) and Kangra (21249).
When compared with the previous year there was an increase both in
the number of primary vaccinations and revaccinations performed during the
year 1922-23 which in the case of the former amounted to 23109 in that of
the latter to 34502. The reason for this increase is already stated in paragraph
6 of this report. Seventeen districts show an increase in numbers primarily
vaccinated while 18 districts recorded an excess in revaccinations. The
increase in revaccination was most marked in Ludhiana (10488), Lahore (6977),
Gurdaspur(6924), Kangra (5686) and Hissar (5244).

The percentage of unknown cases to the total number vaccinated in the year
under report was 5.85 in the case of primary and 19.40 in that of revaccina-
tion. The corresponding figures for the year 1921-22 and 1920-21 were 5.20
and 5.02 in the case of primary and 17.13 and 16.90 in revaccination.

12. The ratio of persons successfully vaccinated by the District Staff
during the year 1922-23 was 33.44 per 1,000 compared with 32.42 in 1921-22
and 7.09 in 1920-21. The average rate during the triennial period under
review was 34.32 as against 36.17 for the previous triennium.

Statement No. I and

13. The total number of operations performed by the Special Vaccina-
tion Staff during the triennium under report was 171730 of which 67607
operations were primary and 104123 were revaccination—the corresponding
figures for the previous triennium being 160822, 82996 and 77826. A
comparison of these figures shows a decrease of 15389 in the case of primary
and an increase of 26297 in that of revaccination. This excess of revaccina-
tion over the figures for primary vaccination is an unsatisfactory feature of the
work of the Special Staff. In 1922-23 the total number of operations performed
by this staff was 59815 (22145 primary and 37670 revaccination) compared
with 68255 (21834 primary and 46421 revaccination) in 1921-22 and 43660
(23628 primary and 20032 revaccinations) in 1920-21. The decrease in the
number of revaccinations during 1922.23 when compared with that of last year
is due to the measures taken to check the tendency of the staff to perform
unnecessary revaccinations in order to make up for the dearth of young infants
and to swell the total figures.
