ABSTRACT
Objective@#To analyze the characterisitics of the death cases suspected to be related to vaccination in Fujian Province from 2012 to 2017.@*Methods@#A total of 33 death cases information which was suspected to be related to the vaccinations from 2012 to 2017 were extracted from Chinese Adverse Events Following Immunization Information System (AEFI). The autopsy reports and the conclusions made by AEFI investigation diagnosis expert committee were collected at the same time. The inoculation data were obtained through the Fujian province Immunization Program Information System. The AEFI incidence, rare vaccine reaction incidences and mortality rates following immunization were figured out to analyze the characterisitics of the death cases associated with vaccination.@*Results@#The age of deuths cases was from 26 days to 52 months. Among 33 cases, 23 were males, and 8 were due to vaccine-related reaction, and the others were due to coincidental events. The number of rare vaccine reaction cases from 2012 to 2017 were 2,3,6,8,7 and 7, respectively. The highest AEFI incidence was measles and rubella combined attenuated live vaccine [38.88 (95%CI: 36.85-40.91)/100 000 dose], and the lowest was trivalent oral poliomyelitis attenuated live vaccine [2.01 (95%CI: 1.73-2.30)/100 000 dose]. The highest rare vaccine reaction incidence was measles and rubella combined attenuated live vaccine [15.04 (95%CI: 13.78-16.30)/100 000 dose], and the lowest was trivalent oral poliomyelitis attenuated live vaccine [0.38 (95%CI: 0.25-0.50)/100 000]. The highest mortality rate was inactivated poliomyelitis vaccine [0.26 (95%CI: 0.04-0.54)/100 000 doses], and the lowest mortality rate was measles, mumps and rubella combined attenuated live vaccine [0.01 (95%CI: 0.00-0.08)/100 000 doses]. The Spearman correlation analysis showed that there were correlations between AEFI incidence and rare vaccine reaction incidence (r=0.64, P=0.048), there were no correlations between AEFI incidence and mortality rate (r=-0.34, P=0.329), and there were no correlations between rare vaccine reaction incidence and mortality rate (r=-0.25, P=0.484).@*Conclusion@#Neither AEFI incidence nor rare vaccine reaction incidence was correlation with mortality rate. The main causes of death following vaccination were coincidental events.
ABSTRACT
We investigated the distribution of Chlamydia trachomatis genotypes in the outpatients visiting STD clinics in Fuzhou City ,China .Between 2013 and 2014 ,a total of 2 019 urethral or endocervical specimens from susceptible genital C .trachomatis infections were collected and detected by using real‐time PCR assay kit .The C .trachomatis‐positive specimens were subsequently amplified with nested PCR for Omp1 region and analyzed by sequencing .Genotyping was performed by BLAST similarity search and phylogenetic tree analysis .Eighty‐three of the 86 C . trachomatis‐positive specimens were suc‐cessfully sequenced .Only one specimen was identified as multiple infection .Eight different genotypes were identified .The most prevalent was F (36 .59% ) ,followed by E (24 .39% ) ,D (12 .20% ) ,G (9 .76% ) ,J (9 .76% ) ,H (3 .66% ) ,K (2 .44% ) and B (1 .22% ) .Synonymous mutation rate and non‐synonymous mutation rate among Omp1 genes of different geno‐types were calculated .All genotypes but G showed dN/dS values of<1 .Genotypes F and E were commonest .Synonymous sub‐stitution was the major pattern of variation in the process of Omp 1 gene evolution .
