Abstract

To study the incidence of cases with rash and fever illness (RFIs) after measles vaccine (MV) inoculation. During 1999 to 2002, 150 RFIs cases reported by the special measles surveillance system in Shandong province, China, were investigated and analyzed epidemiologically. 7 674 690 ml MV were distributed during 1999 to 2002 and the annual average incidence of RFIs cases after MV inoculation was 0.20/10 000 ml (0.2 ml per dose). There was significant difference of incidences each year (chi(2) = 10.13, P < 0.05). All RFIs cases were sporadically distributed without epidemiological links. Clinical symptoms showed that 88.67% of the 150 RFIs cases having > 38.5 degrees C fever and 75.33% of all cases appeared typical rash after 4 to 11 days (the medium was 8 days) after MV inoculation. The order of rash onset among RFIs cases was consistent with that of regular measles cases caused by wild virus. 68.67% of the RFIs cases had first MV inoculation and 94.71% were 8 to 12 month-olds. IgM sera antibody test from RFIs cases were rubella negative and 45.65% positive for measles. RFIs due to allergic reaction or measles vaccine virus infection might occur after MV inoculation. There seemed to be a correlation between RFIs incidence and t...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
