Vaccine safety depends on many factors and one of
the prime ones is its quality. In order to ensure
the best vaccines, irrespective of the cost, the
State of Qatar orders its supply from WHO
recommended countries. A regular check is kept on
their efficacy and quality control is reinforced
through Vaccine surveillance section and supervisory
visits of WHO. More than one company supplies the
vaccine but only those listed as Registered Vaccines
are the main sources for the entire state.
