Objective: To assess the safety and immunogenicity of freeze-dried rabies vaccine (Vero-cells) for human use on different immunization procedures in healthy people aged 9-65 years. Methods: A randomized, blind, positive-controlled clinical study was conducted in March 2015. The eligible residents aged 9-65 were recruited in Dengfeng city and Biyang County, Henan Province. A total of 1 956 subjects were enrolled. The subjects were randomly (1∶1∶1) assigned to 5-dose control group, 4-dose trial group and 5-dose trial group, with 652 subjects in each group. The subjects of 5-dose control group were immunized with control vaccine on days 0, 3, 7, 14 and 28. The subjects of 4-dose trial group were immunized with trial vaccine on days 0, 7 and 21 (2-1-1 phases) and the subjects of 5-dose trial group were immunized with trial vaccine on days 0, 3, 7, 14 and 28. A combination of regular follow-up and active reporting was used to observe local and systemic adverse reactions till 30 days after the first and full immunization, and the incidence rate of adverse reactions in three groups was analyzed and compared. The venous blood was collected before the first immunization, 7 days after the first immunization, 14 days after the first immunization and 14 days after the full immunization. The neutralizing antibody of rabies virus was detected by rapid fluorescent focus inhibition test (RFFIT), and the seropositive conversion rate and geometric mean concentration (GMC) of antibody were calculated. Results: The adverse reaction rates in 5-dose control group, 4-dose trial group and 5-dose trial group were 41.87% (273/652), 35.43% (231/652) and 34.97% (228/652), respectively. The adverse reaction rates of 4-dose trial group and 5-dose trial group were lower than those of the 5-dose control group (P<0.05). The local reactions were mainly pain, itching, swelling and redness in injection site, while the systemic reactions were mainly fever, fatigue, headache and muscle pain. The severity of adverse reactions was mainly mild (level 1), accounting for 85.33% (518/607), 89.02% (373/419) and 88.96% (427/480) of the total number of adverse reactions in each group. At 14 days after the first immunization and 14 days after the full immunization, the antibody positive conversion rates of three groups were all 100%. At 7 days, 14 days after the first immunization and 14 days after the full immunization, the GMCs of three groups were 0.60, 0.72, 0.59 IU/ml, 20.42, 23.99, 24.38 IU/ml and 22.95, 23.52, 24.72 IU/ml, respectively, with no significant difference (P>0.05). Conclusion: The freeze-dried rabies vaccine (Vero-cells) for human use has good safety and immunogenicity when inoculated according to 5-dose and 4-dose immunization procedures.

Objective: To understand the knowledge, attitude and behavior of adult residents on influenza, pneumococcus, human papillomavirus (HPV), herpes zoster (HZ), COVID-19, hepatitis B and rabies vaccination in Shandong Province. Methods: From August to September 2022, a multi-stage stratified random sampling method was used to investigate community-dwelling residents aged 18 years old and above in 12 counties (cities and districts) of Shandong Province. A questionnaire survey was used to collect the basic information of the respondents, such as knowledge, attitude and vaccination behavior of influenza, pneumococcus, HPV, HZ, COVID-19, hepatitis B and rabies vaccine. Analysis of variance was used to compare the differences in the respondents' knowledge and attitude scores of different vaccines. The Chi-square test was conducted to compare the differences in vaccination reasons among different characteristics, and a logistic regression model was used to analyze the influencing factors of vaccination behavior. Results: The median age (Q1, Q3) of the 2 754 respondents was 39 (29, 57) years ranging from 18 to 94 years, with a number of 1 234 (44.81%) males. The average score of the respondents' understanding of various knowledge about adult vaccines was less than 4 points, with the highest score for understanding which diseases can be prevented by adult vaccines. The average score of consent and necessity for adult vaccines to prevent diseases was greater than 3.6 points. In terms of knowledge demand and trust in information channels, there was a high level of trust in the recommendations of vaccination outpatient staff and clinical doctors [with scores of (4.15±0.79) and (4.02±0.80), respectively]. The highest demand for information on vaccination safety knowledge was (4.18±0.84) points. In recent two years, 52.11% of the population had been vaccinated with other vaccines in addition to the COVID-19 vaccine and rabies vaccine, and 45.44% of the population felt it was necessary to be vaccinated through media publicity. Women, age growth, high education level, and high-income level were the promoting factors for adopting vaccination behavior. Conclusion: Adult residents in Shandong Province have a basic understanding and supportive attitude towards vaccination, but the vaccination behavior rate is still relatively low, with significant differences in sex, age, education level, and income level. It is necessary to further increase efforts in the breadth and depth of adult vaccination promotion and education, as well as promotion strategies targeting different populations.

From 2011 to 2020, there were 111 213 cases of rabies exposed people recruited from the rabies immunization clinic of a hospital in Beijing. The monthly distribution of patients in each year was not statistically significant (P>0.05). The distribution of patients showed remarkable seasonality, with the exposure peak from May to October. The ratio of male to female was 1∶1.3. The majority of patients were aged 20-29 years old (39.1%) and in-service personnel (56.5%). Level-Ⅱ wounds (84.2%) were more common than level-Ⅲ wounds (14.9%). The number of visits to level-Ⅲwounds increased rapidly since 2017. The most common injured body part was hand (60.7%). Dogs were the most common animal for injuries (60.6%), followed by cats (32.3%), of which most were host animals (75.5%). The vaccination rate from 2016 to 2020 [49.8% (24 276/48 703)] was significantly higher than that from 2011 to 2015[18.6% (6 559/35 272)](χ²=8597.18, P<0.001).

OBJECTIVE:
Preliminary assessment of rabies virus neutralizing activity, safety and immunogenicity of a recombinant human rabies antibody (NM57) compared with human rabies immunoglobulin (HRIG) in Chinese healthy adults.
METHODS:
Subjects were randomly (1:1:1) allocated to Groups A (20 IU/kg NM57), B (40 IU/kg NM57), or C (20 IU/kg HRIG). One injection was given on the day of enrollment. Blood samples were collected on days -7 to 0 (pre-injection), 3, 7, 14, 28, and 42. Adverse events (AEs) and serious AEs (SAEs) were recorded over a period of 42 days after injection.
RESULTS:
All 60 subjects developed detectable rabies virus neutralizing antibodies (RVNAs) (> 0.05 IU/mL) on days 3, 7, 14, 28, and 42. The RVNA levels peaked on day 3 in all three groups, with a geometric mean concentration (GMC) of 0.2139 IU/mL in Group A, 0.3660 IU/mL in Group B, and 0.1994 IU/mL in Group C. At each follow-up point, the GMC in Group B was significantly higher than that in Groups A and C. The areas under the antibody concentration curve over 0-14 days and 0-42 days in Group B were significantly larger than those in Groups A and C. Fifteen AEs were reported. Except for one grade 2 myalgia in Group C, the other 14 were all grade 1. No SAEs were observed.
CONCLUSION
The rabies virus neutralizing activity of 40 IU/kg NM57 was superior to that of 20 IU/kg NM57 and 20 IU/kg HRIG, and the rabies virus neutralizing activity of 20 IU/kg NM57 and 20 IU/kg HRIG were similar. Safety was comparable between NM57 and HRIG.

Rabies remains a continuous threat to public health in Beijing. In this study, a total of 224 brain tissues were collected from suspected infected stray dogs within Beijing between January 2015 and December 2016. Among them, total of 67 samples were diagnosed positive for rabies. In the phylogenetic analysis, rabies in Beijing is currently a relatively independent public health issue originating from local rabid dogs apart from the imported cases from elsewhere in the country. Because vaccination of unregistered dogs against rabies is still neglected in Beijing and other regions of China, national and local authorities should play central roles in all related aspects, such as development of policies, engagement of stakeholders for public and professional education, entire vaccination process, and animal management.

Post-exposure prophylaxis (PEP) has proved to be the most important measure for rabies prevention and control. There is little information regarding adverse reactions to the Essen and 2-1-1 regimens in preschool children (aged 0-6). We reexamined the outcomes of 1,109 preschool children who were vaccinated using SPEEDA under the Essen regimen between January 2011 and December 2012 and 1,267 preschool children under the 2-1-1 regimen between January 2013 and December 2014. We find that, in preschool children, the febrile reaction after the first 2-dose injection in the 2-1-1 regimen was significantly higher than that induced by the first 1-dose in the Essen procedure. Thus, we recommend that the Essen regimen should still be used for rabies PEP in preschool children.

PURPOSE: Rabies is one of the most fatal diseases, but it is 100% preventable in animals by vaccination. In this study, we present the epidemiological features of, and national preventive measures against, rabies in Korea. MATERIALS AND METHODS: Data related to rabies and the population density of raccoon dogs in Korea were collected from the Animal and Plant Quarantine Agency, the Korean Centers for Disease Control and Prevention, and the National Institute of Environmental Research. Rabies diagnosis was confirmed with a fluorescent antibody test using brain samples of animals in accordance with the procedures described by the World Organization for Animal Health. Serological assays for dogs and cattle were conducted using the fluorescent antibody virus neutralization test. RESULTS: From 1993 to 2016, a total of seven human rabies cases and 437 animal rabies cases in five different species were reported. An increase in the distribution of bait vaccine seemed to be related to a dramatic decrease in rabies prevalence in endemic rabies regions. Two Korean provinces and the capital city, Seoul, were involved in rabies outbreaks. Korean rabies strains are most closely related to the eastern Chinese strain belonging to the Arctic-like lineage. The yearly seropositive rates ranged from 50.4% to 81.2% in dogs and from 25% to 60.5% in cattle residing in endemic rabies regions. CONCLUSION: This study indicates that national preventive measures, including mass vaccination and distribution of bait vaccines, have contributed to a substantial decrease in the number of rabies cases in Korea.

To understand the epidemic situation and factors influencing rabies cases in children in China, we obtained an overview of the current epidemic based on individual data of rabies cases in children and a descriptive analysis was carried on the prevalence and related factors. The results showed that the rabies cases in children accounted for 21.3% of the total number of rabies cases in China, 97.0% of these cases occurred in rural areas, they were mainly caused by dogs (81.5%), and were primarily level III exposure (47.7%). More than half of the cases were not treated with wound care, vaccination rate was extremely low (15.7%), and only 5.9% of cases were injected with antibodies. Furthermore, 25.4% of cases adopted incorrect treatments such as extruding bleed and wound closure, cases vaccinated with 5 injections accounted for only 22.5%. In conclusion, the prevalence of rabies cases in children in China remains a serious concern, the number and immune status of dogs in rural areas, and knowledge of rabies by risk populations should be considered in future rabies prevention and control programs.
