Objective: To analyze the dropout of adsorbed diphtheria, tetanus and acellular pertussis combined vaccine (DTaP) routine immunization in China in 2019. Methods: DTaP vaccination data in all counties in China were collected through National Immunization Program Information Management System in 2019. Cumulative dropout rate and vaccination rate of DTaP in different provinces were calculated. According to the P₂₅, P₅₀ and P₇₅ values of DTaP dropout rate for all counties by province, counties in each province were divided into four groups (Q₁-Q₄). The DTaP average dropout rate of four groups and absolute difference (difference in DTaP average dropout rate between Q₄ and Q₁) were calculated. Spearman rank correlation was used to analyze the relationship between absolute difference and provincial DTaP dropout rate, DTaP₁ and DTaP₃ vaccination rate. Results: DTaP₁ vaccination rate ranged from 92.98% to 99.94% by province, with a median of 99.55%. Provincial DTaP dropout rate ranged from 0.36% to 28.66%, with a median of 3.54%. The provincial DTaP dropout rate was more than 10% in Gansu and Guizhou, about 28.66% and 17.19%. Absolute difference ranged from 4.02% to 39.22%, with a median of 10.16%. Provinces with the largest absolute difference were Gansu, Qinghai, Liaoning and Guizhou, about 39.22%, 34.48%, 23.31% and 21.33%, respectively. Correlation analysis indicated that the absolute difference was positively correlated with provincial DTaP dropout rate, with a correlation coefficient of 0.492 (P=0.004). It was negatively correlated with DTaP₁ and DTaP₃ vaccination rate. Correlation coefficients were -0.542 (P=0.001) and -0.562 (P=0.001), respectively. Conclusions: There are significant county-level differences in DTap dropout rate in most provinces, with relatively high difference in western provinces.

OBJECTIVE: To investigate the status of vaccination in children with human immunodeficiency virus (HIV) infection. METHODS: A questionnaire survey was performed in 148 children in Hunan province, China who were registered in China's Acquired Immune Deficiency Syndrome Comprehensive Response Information Management System up to December 31, 2016 and were aged <15 years at the time of confirmed diagnosis of HIV infection. The information on vaccination, diagnosis of HIV infection, and diagnosis and treatment of related diseases was collected. RESULTS: Of the 148 children with HIV infection, there were 70 boys (47.3%) and 78 girls (52.7%); 140 children had an age of 3.8 (0.2-14.8) years at the time of confirmed diagnosis, and 8 children refused to answer this question. Mother-to-child transmission was found in 133 children (91.7%), blood transmission in 1 child (0.7%), and unknown in 14 children (9.5%). Of the 148 children, 129 (87.2%) received antiviral therapy and 19 (12.8%) did not receive such treatment. The vaccination rates of hepatitis B vaccine, bacille Calmette-Guérin vaccine, poliomyelitis live attenuated vaccine and diphtheria-pertussis-tetanus vaccine ranged from 70.9% to 77.7%, which was significantly lower than the national level (≥97%); the vaccination rates of the other vaccines in the National Immunization Program gradually decreased with age. No severe adverse effects were reported after vaccination. CONCLUSIONS Mother-to-child transmission is the main route of HIV infection in Chinese children. The diagnosis of children with HIV infection is significantly delayed, with low vaccination rates. Efforts should be made to strengthen early diagnosis, early treatment and vaccination in children with HIV infection, in order to improve their quality of life.

OBJECTIVE: To study the clinical features and risk factors of pertussis in children. METHODS: A retrospective analysis was performed for the clinical data and laboratory markers for immune function of 253 hospitalized children with pertussis. A total of 314 hospitalized children with cough were used as the control group. Quantitative real-time PCR was used to detect Bordetella pertussis DNA. The clinical data of both groups were collected to analyze the risk factors for pertussis. RESULTS: A total of 23 typical clinical parameters were compared between the pertussis and control groups, and there were significant differences in only 10 clinical parameters between the two groups (P<0.01). As for the complications observed in the two groups, the pertussis group had a significantly lower incidence rate of myocarditis than the control group (P<0.05). The pertussis group had significantly lower levels of serum globulin and IgM than the control group (P<0.05). Compared with the control group, the pertussis group had a significantly higher proportion of children with a lack of diphtheria-pertussis-tetanus immunization or timely immunization and a contact history of suspected pertussis patients (P<0.05). A lack of vaccine immunization or timely immunization and a contact history of suspected pertussis patients were risk factors for pertussis (P<0.05). CONCLUSIONS The clinical features are not typical in children with pertussis. Quantitative real-time PCR for detecting Bordetella pertussis DNA helps with the early diagnosis of atypical pertussis. Infants/toddlers should be immunized in time and be isolated from suspected pertussis patients to reduce the incidence of pertussis.

Although tetanus and diphtheria have become rare in developed countries, pertussis is still endemic in some developed countries. These are vaccine-preventable diseases and vaccination for adults is important to prevent the outbreak of disease. Strategies for tetanus, diphtheria, and pertussis vaccines vary from country to country. Each country needs to monitor consistently epidemiology of the diseases and changes vaccination policies accordingly. Recent studies showed that tetanus–diphtheria–acellular pertussis vaccine for adults is effective and safe to prevent pertussis disease in infants. However, vaccine coverage still remains low than expected and seroprevalence of protective antibodies levels for tetanus, diphtheria, and pertussis decline with aging. The importance of tetanus–diphtheria–acellular pertussis vaccine administration should be emphasized for the protection of young adult and elderly people also, not limited to children.

BACKGROUND: Adult vaccination is necessary in the prevention of many of the most common infectious diseases because immunity from infant vaccination typically wanes in adulthood In the female population the obstetrician gynecologist is placed at the forefront of health promotion and disease prevention In 2011 the Philippine Obstetrics and Gynecology Society POGS released a Clinical Practice Guideline on Immunization for Filipino Women but no study has been done to determine its impact
OBJECTIVE: This study determined the awareness and practices of OB GYN specialists on adult vaccination and their perceived hindrances to routine administration of the recommended vaccines METHODS: A self administered questionnaire was given to the POGS fellows through email phone and personal visits
RESULTS: Almost all of the respondents 95 were aware of Clinical Practice Guideline on Immunization but only 4 of the OB GYNs routinely administered all the vaccines The most common vaccinne administered was Human Papilloma Virus HPV vaccine 42 7 followed by Influenza virus vaccine 28 1 and Hepatitis B vaccine 27 3 There is no significant relationship between age of the respondent the number of years in practice place of practice affiliation with a teaching hospital or subspeciality training and vaccine recommendation and administration There is a significant positive relationship between awareness of the guidelines and the frequency of recommending the Tetanus Diphtheria Pertussis Tdap vaccine and the Influenza vaccine Similarly awareness of the guidelines was related to increased frequency of administering the Human Papilloma Virus HPV vaccine and the Influenza vaccine
CONCLUSION: Hence adult vaccination coverage may be promoted by increasing the awareness of the obstetrician gynecologists of the POGS Clinical Practice Guidelines on Immunization Although cost remains to be an issue identified by 93 of the respondents increasing awareness among OB GYNs on the importance of adult vaccination through the CPG on Immunization and or through attendance of the Vaccinology 101 Course through vaccinology courses may ultimately help decrease the incidence of some of the most coomon infectious diseases affecting the Filipino women and their children.

We investigated the prevalence of pertussis in Korean adolescents and adults with persistent cough. Study population was adolescents (aged 11-20 yr) and adults (> or = 21 yr old) who showed persistent cough of 1-8 weeks' duration. Pertussis was diagnosed by culture, polymerase chain reaction (PCR), and serology. A total of 310 subjects participated in this study, and 76 cases (24.5%) met the criteria for laboratory-confirmed pertussis. The majority of the pertussis cases (66/76) were confirmed by serology, while 3 cases (1.0%) were diagnosed with culture, and 10 cases (3.2%) were detected with PCR. Of the 76 subjects diagnosed with pertussis, 20/86 cases were adolescents and 56/224 cases were adults. Neither adolescents nor adults received adolescent-adult booster against pertussis within the previous 5 yr. Pertussis can be a primary cause of persistent cough in Korean adolescents and adults.

PURPOSE: The objective of this study was to assess and investigate the epidemiology of pertussis in infants under 6 months of age. METHODS: A prospective study was conducted between October 1, 2011 and April 30, 2013 in CHA Bundang Medical Center, Seongnam, South Korea. Polymerase chain reaction (PCR) or culture was used to detect Bordetella pertussis in nasopharyngeal aspirates from case patients who were hospitalized for acute lower respiratory tract infection (LRTI). In addition, multiplex real-time PCR assays were also performed to detect 6 etiologic viruses, including adenovirus, human metapeumovirus, influenza virus, parainfluenza virus, respiratory syncytial virus and rhinovirus. RESULTS: Of the 79 enrolled case patients, whose median age was 2 months of age, the most common diagnoses uncovered in this study were acute bronchiolitis (60%) and pneumonia (28%). B. pertussis infection was found in 13 cases (16%), in which 7 (53%) was coinfected with respiratory syncytial virus and 1 (7%) with influenza A virus. Of the 13 patients with B. pertussis infection, 6 (46%) were not vaccinated with the diphtheria, tetanus toxoid, and acellular pertussis vaccine, while 6 (46%) received 1 dose, and 1 (8%) received 2 doses. CONCLUSION: B. pertussis infection was present in 16% of under 6 month-old infants, who were hospitalized for acute LRTI. Therefore, a nationwide epidemiological surveillance of pertussis, including institutions that cater to infants under 6 months of age is necessary and needed.

OBJECTIVETo analyze the epidemiological features of adverse events following immunization (AEFI) in Henan Province, China and to evaluate the safety of vaccines currently used in Henan.

METHODSThe AEFI cases reported in Henan from January 1, 2010 to December 31, 2011 were collected through the China Surveillance System of Information on National Immunization Program. The descriptive method was used for epidemiological analysis.

RESULTSA total of 2415 cases of AEFI were reported in Henan from January 1, 2010 to December 31, 2011, and 1238 (51.26%) of them were found in Zhengzhou, Luoyang, and Jiaozuo cities. The male-to-female ratio was 1.32:1. Seven hundred and ninety-nine (33.08%) of these cases were less than one year old. Measles vaccine and DPT vaccine (against diphtheria, pertussis, and tetanus) were the main causes of AEFI, contributing to 61.24% of cases; the incidence rates of AEFI among people receiving measles and DPT vaccines were 30.3/105 and 5.0/105, respectively. 1528 cases (63.27%) developed AEFI after the first dose of vaccination. Inflammation and allergic symptoms were the predominant adverse effects caused by the top 5 vaccines AEFI-causing vaccines, and the clinical manifestations were significantly different among AEFI cases caused by different vaccines (χ2=304.5, P<0.001). Among the 2415 AEFI cases, 1946 (80.58%) had common adverse reaction, 348 (14.41%) had rare adverse reaction, 98 (4.06%) had coupling disease, 13 (0.51%) had psychogenic reaction, and 10 (0.41%) had reaction for unknown reasons. The prognosis of most AEFI cases was good, with a cure rate as high as 90.64%.

CONCLUSIONSAEFI occurs mostly in young children and after the first dose of vaccination. This should be brought to the attention of vaccination service personnel and the children's parents.

PURPOSE: This study was undertaken to evaluate the immunogenicity and reactogenicity of Td booster immunization in early preadolescents of Korea. METHODS: Healthy preadolescents, who had been vaccinated with 4 or 5 doses of DTaP vaccines until 6 years old age, were enrolled in this study from August 2006 to April 2007 . Diphtheria and tetanus anti-toxoid antibodies in sera were measured by ELISA just before vaccination and 4 weeks after vaccination to evaluate immunogenicity. Local and systemic adverse reactions observed for 4 weeks after vaccination to access reactogenicity. RESULTS: 183 preadolescents were enrolled and mean age was 11.40+/-0.51 years old. All subjects achieved seroprotective diphtheria and tetanus anti-toxoid antibodies (titers > or =0.1 IU/mL) after Td booster vaccination. Among 183 vaccinees, 73.8% showed local adverse reactions and 37.2% systemic adverse reactions. Pain at injection site (66.1%) was the most common local reaction, and the most commonly shown systemic reaction was myalgia (17.5%). The adverse reactions were spontaneously relieved within three days after vaccination. CONCLUSION: Td vaccine in this study was high immunogenic and showed an acceptable tolerance in Korean preadolescents. Td booster vaccination at 11 -12 years old is the most effective method to increase compliance of the vaccination and to decrease the incidence of diphtheria and tetanus.
