Objective: To explore the vaccination coverage of the 13-valent pneumococcal conjugate vaccine (PCV13) in China from 2017 to 2021. Methods: Using the reported number of PCV13 administrated doses from 2017 to 2021 and the population data from 31 provinces in China, which were collected by the Immunization Program Information System and summarized data at different levels (prefecture, provincial, and national). Collecting batch release data of PCV13 during the same period through the official website of the National Institutes for Food and Drug Control. The average coverage level of PCV13 was calculated by comparing the number of PCV13 vaccinations reported annually to the number of births in that year, and the spatial auto-correlation analysis was conducted in 2021 at the prefecture level. The coverage of PCV13 vaccination was estimated by the total vaccine doses administered each year divided by the number of newborn in the year, as of the administrated dose number per 100 people. Results: From March 2017 to December 2020, the total batch release of PCV13 was 20.06 million, with a total of 71.54, 384.75, 475.45, and 10.8886 million doses each year. During the same period, PCV13 reported doses were 20.2369 million and the vaccination doses from 2017 to 2021 were 4.08, 170.46, 407.52, 599.77, and 8.4185 million doses, respectively. From 2017 to 2021, the ratio of PCV13 doses administrated per 100 infants in each year was 0.25, 10.26, 23.81, 38.16, and 69.90 doses per 100 people, respectively. The range of the ratio in each province increased from 3.85 doses in 2017 to 264.41 doses per 100 people in 2021. The spatial auto-correlation analysis results showed that based on prefecture-level cities, there was spatial clustering in a certain area of PCV13 coverage from 2017 to 2021, and the spatial correlation in 2021 was the highest. The hotspot analysis showed that the hotspot areas with high coverage levels of PCV13 were concentrated in Jiangsu, Zhejiang, Shanghai, Fujian and their surrounding areas. The cold spots with low vaccine coverage were concentrated in Yunnan, Qinghai, Tibet, and their surrounding areas. Conclusion: The average coverage level of PCV13 is low in China with significant regional differences.

OBJECTIVES: To investigate the potential relationship between age and Streptococcus pneumoniae vaccination coverage in kindergarten children, and to provide a basis for guiding vaccination and developing new protein vaccines. METHODS: The stratified cluster random sampling method was used to select 1 830 healthy children from six kindergartens in Shunde District, Foshan City, China, and nasopharyngeal swabs were collected for the isolation and identification of Streptococcus pneumoniae. The logistic regression model based on restricted cubic spline was used to analyze the dose-response relationship between age and Streptococcus pneumoniae vaccination coverage. RESULTS: The rate of nasal Streptococcus pneumoniae carriage was 22.46% (411/1 830) among the kindergarten children, with the predominant serotypes of 6B, 19F, 15A, 23A, 34, and 23F. The coverage rates of 10-valent pneumococcal conjugate vaccine (PCV10) and 13-valent pneumococcal conjugate vaccine (PCV13) were 53.0% and 57.9%, respectively, and there was a significant non-linear dose-response relationship between age and the coverage rates of PCV10 and PCV13 (P<0.05), with a higher coverage rate of PCV10 (88.0%) and PCV13 (91.1%) in the children aged 2 years. There was a significant non-linear dose-response relationship between age and the coverage rates of pilus islet 1 (PI-1) and pilus islet 2 (PI-2) (P<0.05), with a lower vaccination coverage rate for PI-1 (37.7%) and PI-2 (16.1%). The coverage rates of PI-1 (13.0%-58.5%) and PI-2 (6.0%-29.4%) were lower in all age groups. The virulence genes lytA (99.5%) and ply (99.0%) associated with candidate protein vaccines showed higher vaccination coverage rates. CONCLUSIONS There is a significant non-linear dose-response relationship between the age of kindergarten children and the coverage rates of PCV10 and PCV13 serotypes, and kindergarten children aged 2 years have a relatively high coverage rate of PCV. The high prevalence of the virulence genes lytA and ply shows that they are expected to become candidate virulence factors for the development of a new generation of recombinant protein vaccines.

BACKGROUND: Herpes zoster (HZ) infection can significantly impair the quality of life of the affected individuals, and its treatment imposes a considerable cost burden on the health-care system and on society at large. However, there is little information on the perception of this disease and the acceptability of vaccines in Korea. OBJECTIVE: The aim of this study is to determine the awareness of HZ and its vaccine, and to identify factors associated with the acceptability of the HZ vaccine among outpatients of dermatology clinics. METHODS: A questionnaire-based survey was conducted on 607 outpatients who visited the dermatologic clinics. RESULTS: The responses of the patients revealed a high awareness of HZ (85.4%) but a relatively low knowledge about HZ and its vaccine (42.3%). The HZ vaccination rate among patients aged > or =50 years was 9%. A history of HZ infection, being older, and greater knowledge about HZ and its vaccine were associated with a higher HZ vaccine acceptability. Of those who had not been vaccinated, 58.3% were interested in receiving the vaccine. The most frequent reason for this interest was "severe sequelae," followed by "knowing someone who has HZ" and "recommendation from a doctor." High cost was the most common reason for unwillingness to receive the vaccination. CONCLUSION: Despite a high awareness of HZ, vaccine acceptability was extremely low among this study cohort. Vaccination acceptability would be improved by encouraging doctors to educate elderly patients about the disease and the availability of vaccination, and by the provision of insurance coverage for HZ vaccination.

Objective: To investigate the current situation of influenza vaccination, vaccination willingness, recommended behavior and influencing factors of health care workers (HCWs) under the policy of free vaccination. Methods: A cross-sectional survey was conducted among 3 167 medical staff from 8 hospitals in Nanshan district of Shenzhen city based on a web-based questionnaire platform. The logistic regression was used to analyze the data. Results: The influenza vaccination rate in HCWs was 23.97%, and the recommendation rate was 25.69% from 2019 to 2020. Staff with high professional titles, high academic qualifications, and positive awareness about influenza vaccine had a higher vaccination rate. The main reasons for not recommending influenza vaccine were the fear of patients' misunderstanding of commercial benefits, fear of possible disputes caused by recommended vaccination, lack of national or institutional requirements for recommended influenza vaccine, and fear of adverse reactions of influenza vaccines. Conclusion: Under the free policy, the influenza vaccination rate and recommendation rate of HCWs in Nanshan district of Shenzhen city are relatively low. Strengthening health education on influenza and related knowledge, publicizing the policy of free influenza vaccination, providing convenient vaccination services and promoting the construction of relevant policies and regulations are the key to improve the influenza vaccination rate and recommendation rate among HCWs.

PURPOSE: The purpose of this study was to investigate the health care utilization in Korean women with cervical cancer and cervical intraepithelial neoplasia (CIN). METHODS: This is a retrospective study. Data were collected using the insurance coverage data-base of Health Insurance Review and Assessment Service (HIRA) from January 1, 2006 to December 31, 2010. Women who were treated for cervical cancer and cervical intraepithelial were included in this study. The data were analyzed using descriptive statistics. RESULTS: In 2006, women treated for cervical cancer and CIN were 27,109 and 18,794, respectively. The number constantly increased from 2006 to 2010. In particular, the prevalence among women with cervical cancer aged 80 years or over was found to increase. Claims for health care services increased. CONCLUSION: Even though new cases of cervical cancer in Korea is decreasing, the number of women being treated and the costs are constantly increasing. Cervical cancer patients are at an increased risk of negative health outcomes. Therefore, screening for cervical cancer should be enforced to promptly treat women with abnormal Pap tests and thus minimize the risks. Every effort should be made to increase awareness about the importance of Human Papilloma Vaccination and regular screening on a personal as well as community and governmental levels.

Free medical care is currently a highly debated issue in Korea. However, from a practical point of view, 'completely free' medical care is impossible. Last year the National Health Insurance Corporation (NHIC) reported a huge deficit of up to 1.3 trillion in Korean won, which is the largest deficit in the past 10 years. NHIC expenditures are skyrocketing for many reasons: drug overuse, very expensive new drugs or devices increasing geriatric population and survivors of cancer or chronic illnesses, expanding insurance coverage for new diagnostic tests, drugs, neonates, rare diseases, disabilities, and cancer, occurrence of new diseases, increasing number of doctors, moral hazard, and wasting of resources due to the duplication and counteraction between modern medicine and Oriental medicine. What, then, should we do to provide partially free medical care? We need to reduce expenditures for drugs and increase health insurance premiums. Korean health insurance premium currently low compared to that of other countries in Organization for Economic Co-operation and Development. It is also necessary to introduce the concept of a health tax, in which healthy individuals with a high income pay higher premiums while sick or low-income individuals pay lower premiums. Expanding public health coverage such as vaccinations, regular health surveillance programs, and education on health promotion should be implemented. Private health care insurance can be introduced carefully with close monitoring. The last and most important recommendation is that society must become more ethical and transparent. Korea is entering a new era as a developed country and as a result a welfare system, including medical care is notoptional but is mandatory in some part. However, even a partially free medical care is going to be possible only if the entire health care system is operated in an ethical and efficient way for maximal utilization of limited resources while avoiding moral hazard and waste.

Hepatitis B virus (HBV) infection is the most common cause of chronic liver diseases in Korea. After the introduction of the universal HBV vaccination program, the prevalence of hepatitis B surface antigen was markedly reduced, and Korea is now classified as an area of intermediate endemicity for HBV. However, there are still hurdles for elimination of hepatitis B, such as immunoprophylaxis failure against vertical transmission, occurrence of acute hepatitis B among peoples who did not have vaccination at younger age, and rapid increase of immigrant populations from HBV endemic areas. To achieve the World Health Organization goal of viral hepatitis elimination by 2030 in Korea, we suggest comprehensive policies for more effective control of hepatitis B as following: i) insurance coverage for antiviral prophylaxis in mothers with high viremia, ii) screening for hepatitis B seromarkers and catch-up HBV vaccinations of susceptible persons with hepatitis B, iii) establishment of an independent ‘viral hepatitis sector’ in Centers for Disease Control & Prevention to organize and execute comprehensive strategy for management of viral hepatitis, iv) encourage of management of HBV infection in immigrant populations, v) national campaign to promote awareness of hepatitis B.
