Parental perspective on human papillomavirus (HPV) vaccination in Serbia: Knowledge, attitudes and practice

Parental willingness of HPV vaccination in Mainland China: A meta-analysis

This meta-analysis aimed to systematically review and analyze parental awareness of human papillomavirus (HPV) and its vaccine, as well as parental willingness of the HPV vaccine in China. The literature search selected studies that met the following criteria: study published between 2009 and 2023, study design involving parents with at least one child aged ≤ 18 years, sample sizes exceeding 300, availability of data on parental willingness of the HPV vaccine or sufficient information to calculate effect sizes, and studies published in either English or Chinese. Studies that did not meet one of the above points were excluded. From an initial pool of 660 papers, 33 studies were included, encompassing a total sample size of 92,802. The analysis revealed that the pooled awareness rates of HPV and the HPV vaccine among Chinese parents were 45.0% (95% CI: 36.1-54.0%) and 41.4% (95%CI: 30.7-52.5%), respectively. The overall parental willingness for vaccinating children against HPV was 61.0% (95% CI: 53.5-68.3%). Both parental awareness and willingness of the HPV vaccine in China were found to remain low when compared to other countries.

Assessment of knowledge and perceptions of human papillomavirus vaccine and its determinants among women who have eligible daughters in Debre Berhan City, Ethiopia: a cross-sectional study

Introduction

Globally, cervical cancer(CC) is the second most commonly diagnosed cancer and the fourth leading cause of cancer-related deaths in women. Human papillomavirus (HPV) infection is the leading cause of CC. Persistent infection with HPV accounts for 90% of all CC cases. The human papillomavirus vaccine has the great potential to prevent HPV-related infections for millions of women and men. The current study aimed to assess knowledge and perceptions towards the HPV vaccine and its determinants among women who have eligible daughters in Debre Berhan City, Ethiopia.

Methods

A cross-sectional study was conducted from April 2, 2023, to May 15, 2023. A multistage sampling procedure was used to recruit 607 women participants. Descriptive statistics were used to summarize socio-demographic data. Univariable and multivariable binary logistic regression analyses were performed to measure the associations between the dependent and independent variables. A p-value of <0.05 was considered statistically significant.

Results

More than three-fourths of the participants, 479 individuals (80%) were currently married, and 243(40.1%) had a diploma or higher education level. Of 456(75.12) participants reported, they had information about cervical cancer. For 449(73.9%) of the participants, television was the main evidence. The majority of 352(59.99%) participants knew the HPV vaccine could be offered to a female child aged 9-14 years old. Only 215(35.4%) participants think the HPV vaccine was safe and effective. Women who had a degree and above educational level were about 9 times more likely to have good knowledge about the HPV vaccine than study participants who did not read and write (AOR=9.21; 95% CI=2.82-12.16; p=0.004). Women who did not have information about the HPV vaccine before this study were about 80% less likely to have a positive perception of the HPV vaccine than participants who had earlier information about the HPV vaccine (AOR=0.8; 95%CI=0.63-0.49; P=003).

Conclusion

Women had poor knowledge and perceptions about the HPV vaccine. Maternal marital status, age, and having information about the HPV vaccine were the only predictors of women's knowledge of the HPV vaccine.

Motives and attitudes of parents toward HPV vaccination: Results from the initial period of HPV vaccine rollout in Serbia

Human papillomavirus (HPV) infection is one of the most common viral infections in sexually active population worldwide, and is the main cause of cervical cancer, which is the fourth most common cancer among women. Serbia ranks third in incidence and mortality rate of cervical cancer in Europe. We conducted a cross-sectional study considering parents' motivation for the HPV vaccination of their children. Statistical analysis included descriptive statistics and a logistic regression model. We found that the strongest motive was "Recommendation from paediatrician" (20.2%), followed by the attitude that HPV vaccine protects against cancers in different localization (15.4%), the motive "It is better to vaccinate a child than expose them to potential risk of HPV infection" (13.3%) and "Feeling anxiety due to a possible infection and cancer in the child" (13.1%). For those parents that vaccinated their child for some other strongest motive, reasons like "Vaccine is free of charge", "Recommendation from friends and family" and motive "My child received all obligatory vaccines, so I want to receive this one as well", were significantly more frequently selected. In the group where paediatricians' recommendation was not a motive for accepting the HPV vaccine, the largest percentage of parents (89.6%) selected motive "HPV vaccine protects against cancers in different localization" and the motive "It is better to vaccinate a child than expose them to potential risk of HPV infection" (78.1%). Paediatrician's recommendation is very important for parents' decision to vaccinate, however, other motives also influenced and had significance in making the parents' decision to vaccinate their children against HPV. Encouraging trust in public health authorities in Serbia, highlighting the advantages of the HPV vaccine and further encouraging healthcare workers to give stronger recommendations can increase the HPV vaccine uptake. Finally, we provided the basis to create more targeted messages that will empower parents to vaccinate their children.

Cervical Cancer Prevention Knowledge (Cckp-64) among Female Students in Novi Sad, Serbia during COVID-19 Pandemic

Cervical cancer is a significant global health concern affecting young women, with over 500,000 new cases reported annually. This questionnaire-based study aimed to evaluate the knowledge of cervical cancer prevention among female students at the University of Novi Sad during the COVID-19 pandemic using the Cervical Cancer Knowledge Prevention-64 (CCKP-64) tool. The study sample consisted of 402 predominantly 20-22-year-old female students from either social or technical science faculties in urban environments. Results revealed that out of the 402 female students involved in the study, most had a good general knowledge of primary prevention of cervical cancer, with a correct answer rate ranging from 29.9 to 80.6%. On the contrary, only 63.4% of female students have heard about the vaccine against cervical cancer; 52.0% know that the vaccine exists in Serbia; and 31.8% know where to get vaccinated. Only a small proportion of students (9.7%) have encountered cervical cancer among their relatives/friends and think that the disease could affect them in the future (25.4%). Older students (>26 years) generally (p < 0.05) had better knowledge regarding distressing symptoms of cervical cancer, cytological examination and secondary prevention; however, it was also noted that a significant percentage of this age group reported not having received vaccinations (53.0%, p = 0.001). This study underscores the need for increased awareness and education about the HPV vaccine and secondary prevention among young women in Serbia. Future research should investigate knowledge and attitudes toward cervical cancer prevention in diverse populations to develop effective interventions and strategies. These findings have implications for public health policies in Serbia to promote cervical cancer prevention among young women.

Human papillomavirus-specific antibody status among unvaccinated subjects in the region of Vojvodina, Serbia

OBJECTIVES

The aim of the study was to evaluate the immune status of young people from the Vojvodina province, Serbia, through the detection of IgG antibodies specific for the L1 protein of HPV types 6, 11, 16, and 18 contained in quadrivalent vaccine.

METHODS

The study enrolled 514 healthy persons of both genders, aged between 18 and 30 years. All potential participants were informed about the project's aims by trained interviewers before venous blood collection. Also, participants completed a specially designed anonymous questionnaire to identify socio-demographic characteristics and individual behaviours associated with HPV seroprevalence. VPL HPV L1-specific IgG antibodies were measured using a semi-quantitative HPV IgG ELISA kit (Dia.Pro, Italy).

RESULTS

A total of 472 (91.8%) young subjects had no detectable antibodies against high- and low-risk HPV types covered by the quadrivalent vaccine. A slightly higher number of seropositive individuals were detected in the age group of 26-30 years compared to younger than 25. Multivariate analysis showed that the number of lifetime sexual partners was the most powerful predictor of HPV seropositivity (OR = 3.483, 95% CI: 1.294-9.379).

CONCLUSIONS

Obtained data point out low levels of naturally induced HPV-specific serum antibodies among the target population in the Vojvodina province. The present work highlights the significance and potential benefits of HPV vaccination. Routine HPV vaccination should be the public health priority in our country and should be included in the national immunization programme as soon as possible.

Knowledge and attitudes of mothers toward HPV vaccination: A cross-sectional study in Kazakhstan

BACKGROUND

Although recommended for all member states of World Health Organization, there is no national human papillomavirus vaccination program in Kazakhstan. Furthermore, there are no studies in Kazakhstan that evaluate the mothers' perception of human papillomavirus vaccines.

OBJECTIVES

This study aims to assess the knowledge and attitudes toward human papillomavirus vaccination among mothers in Kazakhstan and the factors associated with their attitudes.

DESIGN

A cross-sectional study was performed during the period of December 2021-February 2022. The STROBE guideline for cross-sectional studies was applied.

METHODS

Paper-based structured questionnaires were filled out by 191 mothers, 141 of whom had daughters. The attitude score was assessed as per the Likert-type scale. The Chi-square and Fisher's exact tests, with a significance value of < 0.05 were used to analyze the relationships between the characteristics of mothers and their attitude scores.

RESULTS

The following factors were significantly associated with mothers' attitudes toward human papillomavirus vaccination: a place of residence, family income, number of children, and refusal of vaccination for themselves (p < 0.005). Of all participants, only 45% of all mothers, 41% of mothers with a female, and 46% of mothers with male children had positive attitudes toward human papillomavirus vaccination. The child's gender was not a significant determinant. Overall, the level of knowledge about human papillomavirus vaccination was found to be low. The median total score is 0 out of 12 for women who have negative and neutral attitudes toward human papillomavirus vaccines. Among women who have positive attitudes toward HPV vaccines, the median score is around 3 points.

CONCLUSION

Before the implementation of the human papillomavirus vaccination program into the Kazakhstani national vaccination calendar, comprehensive and adequate information and education campaigns are required on the national level for parents and the population in general.

Factors affecting children's HPV vaccination in Austria: Evidence from a parent survey

Human papillomavirus (HPV) is a sexually transmitted infection that causes cervical cancer, head and neck cancer, other urogenital cancers, and genital warts. In Austria, where HPV vaccination is free for children, the vaccination rate nevertheless remains insufficient for herd immunity against HPV. Using a cross-sectional survey of parents (N = 334) in the state of Tyrol, Austria, we examined parents' reasons for rejecting children's HPV vaccination and key predictors of vaccination intention for their children, including knowledge about HPV, attitude toward vaccination, sources of information about the HPV vaccine, socioeconomic factors, and HPV vaccination intention. Data analyzed using descriptive statistics and logistic regression modeling revealed an overall 81.9% acceptance rate of HPV vaccination. The most common reasons for vaccine hesitancy were a fear of side effects, a perceived lack of information, and the perception that children are too young to be vaccinated. A high level of knowledge about HPV was significantly associated with vaccine acceptance for female but not male children. Negative attitude toward vaccination was significantly related to lower vaccine acceptance, and parents who reported informing themselves about HPV vaccination from online sources were less likely to accept vaccination. Such results call for more educational measures to reduce misinformation about HPV vaccination and thereby reduce the fear of its side effects and promote early vaccination. More information is also needed to improve parents' attitude toward and their knowledge about vaccination, the dissemination of which should focus on the benefits of vaccines for children of both sexes.

Knowledge and Attitude Towards Human Papillomavirus Vaccine and Associated Factors Among Mothers Who Have Eligible Daughters in Debre Markos Town, Northwest Ethiopia

Purpose

This study aimed to assess knowledge and attitude towards the human papillomavirus vaccine and associated factors among mothers who have eligible daughters.

Methods

A community-based cross-sectional study with a total sample of 601 study participants was conducted in Debre Markos town from February to March 2021. The study participants were selected using a multistage sampling technique from mothers who have eligible daughters. The data was collected using an interview administration questionnaire. The data were entered into EPI data version 3.1 then, exported to SPSS version 25 for analysis. Variables with a p-value of < 0.25 in bivariate were a candidate for multivariate and those variables with a p-value of <0.05 in multivariate binary logistic regression were considered as a statistically significant factor for knowledge and attitude of the HPV vaccine.

Results

A total of 601 study participants with a response rate of 100% were included in the study. Among participants in this study, 47.6% have good knowledge and 77.4% have a positive attitude towards the HPV vaccine. Knowledge of mothers about HPV vaccine was affected by having degree and above (adjusted odds ratio (AOR) =7.687; 95% CI=1.837–32.168; p=0.005), did not hear about HPV vaccine (AOR=0.172; 95% CI=0.098–0.302; P=0.000), and positive attitude towards HPV vaccine (AOR=2.959; 95% CI=1.580–5.539; P=0.001). Attitude of mothers towards HPV vaccine was affected by did not hear about HPV vaccine (AOR=0.285; 95% CI=0.163–0.499; P=000), and good knowledge about HPV vaccine (AOR=2.705; 95% CI=1.454–5.035; 0.002).

Conclusion

Knowledge of mothers who have eligible daughters about HPV vaccine was low. Maternal educational level, hearing about the HPV vaccine, and attitude towards HPV vaccine were significantly associated predictors with knowledge towards HPV vaccine. However, the attitude was high and factors associated with attitudes towards the HPV vaccine were knowledge about the HPV vaccine and hearing about the HPV vaccine. An integrated work should be considered by Debre Markos town health office with other non-governmental organizations working on health and health-related issues to improve knowledge about the importance of HPV vaccine for mothers who have eligible daughters.

Barriers towards HPV Vaccinations for Boys and Young Men: A Narrative Review

Background: HPV vaccination of both girls and boys can protect against infection and eliminate the risk for HPV-associated cancer. Due to a common misconception that the virus only poses risks to women, vaccine coverage is suboptimal among men in many countries. It is urgent to identify barriers to vaccination of boys and men. Methods: We conducted a narrative review of publications examining attitudes and beliefs regarding HPV vaccination for boys and young men. The electronic databases searched were PubMed, PsychInfo and Scopus (December 2020; last update July 2021). A total of 103 original articles were included in the final analysis. Results: The central barriers against vaccination of boys and men are: (1) lack of knowledge, (2) vaccine hesitancy in general, (3) lack of recommendation from and/or discussions with healthcare providers, (4) cost and logistics, and (5) the idea that HPV vaccination may promote promiscuity. Men who have sex with men and families belonging to ethnic minorities express a need for information tailored to their situation. Conclusions: Boys should be included in national immunization programs and men should also be offered catch-up vaccinations. Future studies should focus on addressing vaccine hesitancy and developing interventions to promote pan-gender HPV vaccination.

Uptake of Human Papillomavirus Vaccine and Intention to Vaccinate among Healthy Pregnant Women in Serbia: A Cross-Sectional Study on Awareness, Knowledge, and Attitudes

We aimed to assess awareness, knowledge, and attitudes of healthy pregnant women towards human papillomavirus (HPV), to estimate factors associated with a positive attitude towards HPV immunization and to assess the uptake of the vaccine among their children. A cross-sectional study was conducted at the University Clinic of Gynecology and Obstetrics, Belgrade, Serbia among pregnant women attending their regular gynecological check-ups at the 12th gestational week. Knowledge about HPV and HPV vaccine was assessed using a specifically designed 12-item and 5-item questionnaires. Out of total 265 included women, 79.3% had heard of HPV, and 37.5% knew that HPV vaccine exists. HPV vaccine knowledge score was associated with higher odds for a positive attitude towards vaccination of both female (OR = 4.10, 95% CI 1.50-11.29) and male (OR = 3.71, 95% CI 1.52-9.01) child. The number of children (OR = 1.32, 95% CI 1.04-1.67) and high vaccine knowledge score (OR = 1.64 95% CI 1.13-2.39) were independent predictors associated with willingness to vaccinate child against HPV. The gynecologist was the preferable point of reference for information seeking about the HPV vaccine. Despite relatively high HPV awareness and knowledge among pregnant women in Serbia, about one-third of them are HPV vaccine aware, and are willing to vaccinate their children against HPV.

HPV vaccine hesitancy among parents in Italy: a cross-sectional study

This cross-sectional survey determined the vaccine hesitancy related to Human papillomavirus (HPV) and the determinants among parents of adolescents aged 12 and 13 years in Italy. Data was collected through a self-administered questionnaire. Two-thirds of the parents (66.7%) had heard of HPV infection and knew that the vaccination was a preventive measure. Parents who had vaccinated their child against the HPV were more likely to have this knowledge. The vast majority (88%) considered the immunization useful for the prevention of HPV-related cancers with an average value of 8.4. This positive attitude was higher among parents who had heard of HPV infection and knew that vaccination was a preventive measure, who had received information from physicians, who had vaccinated their child against the HPV, who were concerned that their child could contract the HPV infection, and who needed information on HPV vaccination. More than half (57.9%) self-reported that they had vaccinated their child against HPV and only 6.2% had delayed the administration of a dose. One-third (33.3%) were hesitant toward anti-HPV vaccination with a total Parent Attitudes about Childhood Vaccines Survey (PACV) score ≥50. Unmarried respondents, those who had not heard of HPV infection and did not know that the vaccination was a preventive measure, who did not believe that the vaccination was useful for the prevention of HPV-related cancers, and who needed information on HPV vaccination were more likely to be hesitant. Communication and education strategies must be undertaken to ensure that parents are fully informed and health-care professionals should provide materials with details regarding the risk of acquiring a HPV infection and vaccine usefulness.
