As the success rates among re-vaccinations are subject to great fluctuations
on account of the varying amounts of immunity among the revaccinated
persons, inferences on the ratios contained in the last four columns of the above
statement are apt to be misleading as they are based on the total operations
including revaccinations. If the success rates among the primary and secondary
vaccinations alone are considered, the progressive improvement in the rates
recorded among the vaccinations done in local fund and municipal areas which
comprise over 95 per cent of the total operations is extremely gratifying. The
percentage of success has increased in the primary and secondary vaccinations
in rural areas from 94.7 to 96.4 and in municipal areas from 98.1 to 98.9. It is.
only natural to expect the maximum rate of success in municipalities on account
of the facilities for the prompt delivery of lymph and for its expeditious use.
The slight decrease in the percentage of success in the work of the Govern¬
ment vaccinators who are employed in the Agency is apparently due to the
adverse conditions in connexion with transportation which affect the potency of
the lymph.
The reasons for the progressive decline in the success rate among the
operations of the Cantonment vaccinators have not been explained in the reports.
The attention of the authorities concerned will be drawn.
It is a matter for great surprise that the rate of success in the primary and
secondary vaccinations done by medical subordinates was as low as 65.9 during
the year. This needs investigation.
The statistics relating to the other agencies are comparatively small and do
not call for any special remarks.
