Abstract

OBJECTIVE:

This retrospective study is aimed to investigate the clinical features of the patients with history of incomplete vaccination against hemorrhagic fever with renal syndrome (HFRS).

METHODS:

Data of 140 cases of hospitalized patients with HFRS were collected. The patients were divided into incomplete vaccinated group (n = 10) and unvaccinated group (n = 130) according to vaccination status. Demographic, clinical, and laboratory characteristics of the two groups' patients were compared through t test, Pearson χ(2) test, and Mann-Whitney test.

RESULTS:

In comparison with the unvaccinated group, the incidence rate of vomiting and hypotensive-shock, the white blood cell (WBC) and platelet count, the level of blood urea nitrogen and albumin, total number of dialysis and hospitalization cost of patients in the incomplete vaccinated group have statistically significant differences.

CONCLUSION:

HFRS disease may still occur in individuals with a history of HFRS incomplete vaccination although the symptoms may be mild. Effective vaccination against HFRS needs sufficient doses and booster shot of the vaccine.
