Background The thirteen-valent pneumococcal conjugate vaccine(PCV13)is not included in the national immu-nization program and is administered voluntarily with informed consent in *** preparation for assessing the impact of pilot introduction in Hainan Province,we conducted a carriage study among children under 5 years of age from four locations in Hainan Province,*** From March to June 2022,nasopharyngeal(NP)swabs,collected from healthy children aged younger than 59 months who lived in the 4 different locations(Haikou,Wanning,Baisha and Qiongzhong)in Hainan Province,were tested for pneumococcus using conventional *** isolates were serotyped using the Quel-lung *** factors associated with pneumococcal colonization were assessed using univariate analysis and multivariable logistic regression adjusting for age,daycare attendance and other *** Pneumococcus was isolated in 710(30.4%)of the 2333 children *** 737 pneumococci,29 serotypes were identifed;60.9%were PCV13 serotypes;the most common vaccine serotypes were 6B(20.4%),19F(13.0%),6A(11.9%)and 23F(6.1%);and the most common nonvaccine serotypes were 23A(12.9%),34(6.1%)and nontypeable(NT)pneumococci(5.6%).Children vaccinated with PCV13 had lower carriage(17.7%vs 32.5%;P=0.0001)and fewer PCV13 serotypes(41.9%vs 62.7%;P=0.0017)compared to unimmunized *** adjustment,NP carriage Was higher among children attending daycare(aOR=2.3,95%CI:1.7-3.2),living in rural areas(aOR=1.4,95%CI:1.1-1.8),living with siblings(aOR=1.3,95%CI:1.0-1.6)and whose mothers had completed senior high/technical sec-ondary school(aOR=1.5,95%CI:1.1-2.0).In contrast,completion of 3-4 doses of PCV13 were associated with a lower carriage rate(aOR=0.6,95%CI:0.4-0.9).Conclusions We established the baseline of pneumococcal carriage,serotype distribution and PCV13 immuni-zation rates among healthy children under 5 years of age in Hainan Province,prior to the introduction of PCV13 into th

Objective This study aimed to compare the current Essen rabies post-exposure immunization schedule(0-3-7-14-28)in China and the simple 4-dose schedule(0-3-7-14)newly recommended by the World Health Organization in terms of their safety,efficacy,and *** Mice were vaccinated according to different immunization schedules,and blood was collected for detection of rabies virus neutralizing antibodies(RVNAs)on days 14,21,28,35,and 120after the first ***,different groups of mice were injected with lethal doses of the CVS-11 virus on day 0,subjected to different rabies immunization schedules,and assessed for morbidity and death *** a clinical trial,185 rabies-exposed individuals were selected for post-exposure vaccination according to the Essen schedule,and blood was collected for RVNAs detection on days 28and 42 after the first *** A statistically significant difference in RVNAs between mice in the Essen and 0-3-7-14 schedule groups was observed on the 35th day(P0.05)in RVNAs levels at any time *** post-exposure immune protective test showed that the survival rate of mice in the control group was 20%,whereas that in the immunization groups was 40%.In the clinical trial,the RVNAs positive conversion rates on days 28(14 days after 4 doses)and 42(14 days after 5 doses)were both 100%,and no significant difference in RVNAs levels was observed(P>0.05).Conclusion The simple 4-dose schedule can produce sufficient RVNAs levels,with no significant effect of a delayed fourth vaccine dose(14–28 d)on the immunization potential.
