insusceptible. There were also 266 who died unvaccinated, and 1,973 statutory
declarations of conscientious objection to vaccination were obtained by the parents
or guardians; 44 vaccinations were postponed under medical authority, 294 were
removed to other districts or place unknown, thus leaving 266 unaccounted for.
