Observation on the Side Effect of Inoculation with Vi-polysaccharide Vaccine against Typhoid Fever

The side effect of Vi-polysaccharide vaccine was studied. A group of 60,20-54 years old, healthy individuals who previously no infected with typhoid fever and no vaccinated against typhoid fever was observated. They were random divided into two groups: test group and control group. Test group was inoculated with 30ug Vi-polysaccharide vaccine. After injection, no middle and serious body temperature reaction produced, only one individual emerged erythematous-edemtous reaction. In addition, blood pressure and heartbeat rate was not affected, red cell count and white cell count were in normal ,the ratio of white cell divide no changed.Our results indicated that the side effect of Vi-polysaccharide vaccine was slight. It was suggested that Vi-polysaccharide vaccine might be vaccinated in large amounts.
