It is pointed out in the passage that, as part of the relief work following a disaster, ____ .
When there has been a serious disaster such as an
earthquake or flooding, various relief efforts are rapidly
put into effect. However, experience has shown that it is
usually impractical to attempt mass immunisation
immediately following a disaster and that, when
attempted, it detracts from the overall relief effort without
producing a discernible benefit. Effective immunisation
requires prior planning good systems of communication
and transport and access to the population at risk. These
requirements cannot be met in the immediate postdisaster
period. Efforts to achieve mass vaccination in the relief
phase also drain whatever limited manpower,
communication facilities, and transportation exist.
