This 9th annual immunisation coverage report shows data for 2015 derived from the Australian Childhood Immunisation Register and the National Human Papillomavirus (HPV) Vaccination Program Register. This report includes coverage data for ‘fully immunised’ and by individual vaccines at standard age milestones and timeliness of receipt at earlier ages according to Indigenous status. Overall, ‘fully immunised’ coverage has been mostly stable at the 12- and 24-month age milestones since late 2003, but at 60 months of age, coverage reached its highest ever level of 93% during 2015. As in previous years, coverage for ‘fully immunised’ at 12 and 24 months of age among Indigenous children was 3.4% and 3.3% lower than for non-Indigenous children overall, respectively. In 2015, 77.8% of Australian females aged 15 years had 3 documented doses of HPV vaccine (jurisdictional range 68.0–85.6%), and 86.2% had at least one dose, compared to 73.4% and 82.7%, respectively, in 2014. The differential of on-time vaccination between Indigenous and non-Indigenous children in 2015 diminished progressively from 18.4% for vaccines due at 12 months to 15.7% for those due at 24 months of age. In 2015, the proportion of children whose parents had registered an objection to vaccination was 1.2% at the national level, with large regional variations. This was a marked decrease from 1.8% in 2014 and the lowest rate of registered vaccination objection nationally since 2007 when it was 1.1%. Medical contraindication exemptions for Australia were more than double in 2015 compared with the previous year (635 to 1,401).

Data Point

This tenth annual immunisation coverage report shows data for the calendar year 2016 derived from the Australian Immunisation Register (AIR) and the National Human Papillomavirus (HPV) Vaccination Program Register. After a decade of being largely stable at around 90%, ‘fully immunised’ coverage at the 12-month assessment age increased in 2016 to reach 93.7% for the age assessment quarterly data point in December 2016, similar to the 93.4% for the age assessment quarterly data point in December 2016 for 60 months of age. Implementation of the ‘No Jab No Pay’ policy may have contributed to these increases. While ‘fully immunised’ coverage at the 24-month age assessment milestone decreased marginally from 90.8%, in December 2015, to 89.6% for the age assessment quarterly data point in December 2016, this was likely due to the assessment algorithm being amended in December 2016 to include four doses of DTPa vaccine instead of three, following reintroduction of the 18-month booster dose. Among Indigenous children, the gap in coverage assessed at 12 months of age decreased fourfold, from 6.7 percentage points in March 2013 to only 1.7 percentage points lower than non-Indigenous children in December 2016. Since late 2012, ‘fully immunised’ coverage among Indigenous children at 60 months of age has been higher than for non-Indigenous children. Vaccine coverage for the nationally funded seasonal influenza vaccine program for Indigenous children aged 6 months to <5 years, which commenced in 2015, remained suboptimal nationally in 2016 at 11.6%. Changes in MMR coverage in adolescents were evaluated for the first time. Of the 411,157 ten- to nineteen-year-olds who were not recorded as receiving a second dose of MMR vaccine by 31 December 2015, 43,103 (10.5%) of them had received it by the end of 2016. Many of these catch-up doses are likely to have been administered as a result of the introduction on 1 January 2016 of the Australian Government’s ‘No Jab No Pay’ policy. In 2016, 78.6% of girls aged 15 years had three documented doses of HPV vaccine (jurisdictional range 67.8–82.9%), whereas 72.9% of boys (up from 67.1 % in 2015) had received three doses.

This eleventh national annual immunisation coverage report focuses on data for the calendar year 2017 derived from the Australian Immunisation Register (AIR) and the National Human Papillomavirus (HPV) Vaccination Program Register. This is the first report to include data on HPV vaccine course completion in Aboriginal and Torres Strait Islander (Indigenous) adolescents. ‘Fully immunised’ vaccination coverage in 2017 increased at the 12-month assessment age reaching 93.8% in December 2017, and at the 60-month assessment age reaching 94.5%. ‘Fully immunised’ coverage at the 24-month assessment age decreased slightly to 89.8% in December 2017, following amendment in December 2016 to require the fourth DTPa vaccine dose at 18 months. ‘Fully immunised’ coverage at 12 and 60 months of age in Indigenous children reached the highest ever recorded levels of 93.2% and 96.9% in December 2017. Catch-up vaccination activity for the second dose of measles-mumps-rubella-containing vaccine was considerably higher in 2017 for Indigenous compared to non-Indigenous adolescents aged 10–19 years (20.3% vs. 6.4%, respectively, of those who had not previously received that dose). In 2017, 80.2% of females and 75.9% of males aged 15 years had received a full course of three doses of human papillomavirus (HPV) vaccine. Of those who received dose one, 79% and 77% respectively of Indigenous girls and boys aged 15 years in 2017 completed three doses, compared to 91% and 90% of non-Indigenous girls and boys, respectively. A separate future report is planned to present adult AIR data and to assess completeness of reporting.

Australian Immunisation Register data have been analysed for children aged < 5 years, focusing on changes in vaccination coverage at standard age milestones (12, 24 and 60 months) between 2018 and 2019. ‘Fully vaccinated’ coverage in 2019 increased by 0.1–0.4% at the three age milestones to 94.3% at 12 months, 90.2% at 24 months (in the context of additional antigens required at 24 months) and 94.2% at 60 months. Rotavirus vaccine coverage (2 doses) increased from 90.9% in 2018 to 91.9% in 2019. ‘Fully vaccinated’ coverage in Aboriginal and Torres Strait Islander (hereafter respectfully referred to as Indigenous) children increased by 0.5–1.1% in 2019, reaching 92.9% at 12 months, 88.9% at 24 months and 96.9% at the 60 months (2.7 percentage points higher than in children overall). Recorded influenza vaccination coverage in children aged 6 months to < 5 years increased by 11.4 percentage points to 42.7% in Indigenous children in 2019, and by 15.6 percentage points to 41.8% in children overall. Longstanding issues with timeliness of vaccination in Indigenous children persisted, although the disparity between Indigenous and non-Indigenous children in on-time coverage (within 30 days of due date), for vaccines due at 4 months of age, decreased from 10.4–10.7 to 9.6–9.8 percentage points between 2018 and 2019. The timeliness of ‘fully vaccinated’ coverage was also examined at earlier age milestones (3 months after due date of last scheduled vaccine) of 9, 15, 21 and 51 months, by Indigenous status, socioeconomic status and remoteness of area of residence. Coverage in children living in the least-advantaged residential area quintile was 2.6–2.7% lower than that for those living in the most-advantaged quintile at the 9-, 15- and 21-month milestones, although these disparities were 0.5–1.5 percentage points lower than in 2018. Coverage at the earlier milestones in Indigenous children in remote areas was 1.5–6.7% percentage points lower than that for Indigenous children in major cities and regional areas, although there were some improvements since 2018. Importantly, although Indigenous children had lower coverage for the second dose of measles-mumps-rubella vaccine at 24 months (92.7% versus 93.3% overall), coverage increased to 98.8% at 60 months; coverage was also high overall at 96.4%, above the 95% target critical to measles control. In conclusion, this report demonstrates continuing improvements across a range of immunisation indicators in Australia in 2019. However, some issues with timeliness persist, particularly in Indigenous and socioeconomically disadvantaged children. New coverage targets for earlier protection in the first 2 years of life may be indicated, along with a review of current ‘fully vaccinated’ assessment algorithms, particularly at the 60-month age milestone.

The Relationship

Persistent infection with high-risk Human Papilloma Virus (HPV) has been identified as the causal factor of cervical cancer, with relative risk up to 300-400 folds. This very close relationship leads to the preventive strategy of vaccination against HPV infections and HPV-related lesions. The article describes molecular and immunologic characteristics of HPV, currently available HPV vaccines and its protective effects; the relationship between HPV vaccination and cervical cancer screening, and an introduction to therapeutic HPV vaccine trials.

Data suggest that adjuvant human papillomavirus (HPV)-vaccination in women treated for cervical HPV diseases reduces recurrent disease. This study investigates adjuvant HPV-vaccination and the rate of recurrence in women undergoing surgery for vulvar high-grade squamous intraepithelial lesions (HSIL). From January 2013 to April 2020, we enrolled 149 women in a prospective case-control study. The control group (NV-group) was treated by standard surgery alone, while the study group received adjuvant vaccination soon after surgery (V-group). A follow-up was performed by vulvoscopy and HPV test. Statistical analysis was performed by Fisher’s exact test. HSIL recurrence was observed in 24/76 (32%) patients in NV-group and in 8/42 patients (19%) of the vaccinated group. By analysing the recurrence rate related to the incident and reactivated latent HPV infection, we found a significant difference between (17/76) 22.3% in NV-group and (2/42) 4.8% in V-group (p = 0.01). A reduction of 78.5% in incident/reactivated HPV infections was demonstrated. Data results add to the current knowledge about the mechanism of post-surgical adjuvant HPV vaccination. Our prospective study is the first to document the vaccine clinical effectiveness in preventing “reactivation” of latent HPV infections. Quadrivalent HPV vaccine administered after the surgical treatment for vulvar HSIL appears to be useful in preventing recurrent disease.

Policy Window

Persistent human papillomavirus (HPV) infections can cause cancer (e.g., cervical/vaginal/penile/anal/oropharyngeal). The HPV vaccine prevents cancer, yet U.S. vaccination rates remain low. We explored sociopolitical factors in the adoption of Puerto Rico’s HPV vaccine school-entry requirement. Multiple streams framework explains how the intersection of problems, policy, and politics streams influence policy adoption. Policy entrepreneurs work on joining these streams. Interviews ( n = 20) were conducted with stakeholders (e.g., physicians/researchers/nonprofit organizations’ leaders). Data were analyzed using applied thematic analysis. High incidence of HPV and HPV-related cancers in Puerto Rico were indicators of problems. Focusing events included Rhaiza’s case and the HPV-Advisory Panel Report. During summer 2017, a policy window opened; the Department of Health (DOH) adopted the requirement in summer 2018. Stakeholders discussed policy initiatives. Political turnover positively influenced the process. Policy entrepreneurs created an extended period of intersection resulting in the adoption of the requirement. Findings can inform policy initiatives to improve HPV vaccination rates and reduce HPV-related cancers.

Vaccine Initiation

Native Hawaiian and Pacific Islander (NHPI) adults bear a disproportionate burden of certain human papillomavirus (HPV)-associated cancers. In 2015, data from the National Health Interview Survey (NHIS) showed vaccination coverage among adults by racial and ethnic groups; however, coverage data for NHPI adults were unavailable. In this study, we estimated the initiation and completion of HPV vaccination and assessed the factors associated with vaccination among NHPI adults aged 18 to 26 years in the United States. We analyzed public data files from the 2014 NHPI NHIS (n = 1204). We specified sampling design parameters and fitted weighted logistic regression models to calculate the odds of HPV vaccine initiation. We developed a directed acyclic graph to identify a minimally sufficient set for adjustment and adjusted for insurance coverage (for education and ethnicity) and doctor visit (for insurance coverage, earnings, ethnicity, and sex). Overall, 24.9% and 11.5% of NHPI adults had initiated and completed the HPV vaccination series, respectively. Weighted logistic regression models elucidated that the odds of HPV vaccine initiation were higher for females (weighted odds ratio = 5.4; 95% confidence interval = 2.8-10.4) compared with males. Low vaccination coverage found among NHPI adults provides an opportunity for targeted programs to reduce the burden of HPV-associated cancers.

Abstract Background Immune dysfunction related to HIV infection is associated with an inability to clear HPV infection and may compromise the immunogenicity of quadrivalent HPV vaccine Gardasil® (4v HPV). Methods Between 2005 and 2017, males and females 7 to 20 years old age, were offered 3-dose 4v HPV vaccine. Plasma IgG titers to HPV 6 (H6), 11 (H11), 16 (H16) and 18 (H18) were measured using multiplex VLP-based ELISA. For the 36 patients, median interval from 1st dose to 2nd and 3rd doses were 73 and 216 days. Plasma sample 1 was collected at median of 91 days after dose 1, sample 2, 169 and sample 3, 740 after respective vaccine doses. A 4th sample was available for 26 patients, median 2327 days after dose 1. Rank-sum test, Χ 2 or Fisher’s Exact Test were employed. Results Before vaccination, 10 (28%) were seropositive to 1 or more HPV types. The baseline seropositives were older than seronegatives (16 years vs 11; p=0.007). After dose 3 all participants had an Ab response to at least 1 HPV type and 32 (89%) were seropositive for 4 HPV types. Seroconversions were H18, 87%; H16 97%; H11, 100%; H6, 97%. Seroconversions after 1 dose of 4v HPV among the baseline seronegatives were 61%, 90%, 86% and 86%, respectively and 22 became seropositive for all 4 types. The 4 baseline seronegative PLWH with partial seroconversion had higher median HIV viral load (VL) compared to baseline seronegative group with full seroconversion (12,920 vs 101 copies/ml; p = 0.052), but had comparable CD4 counts. The rate of post vaccination seropositivity and baseline to peak titer response for each HPV type was not significantly different for baseline sero-groups. Among baseline seronegative, all 19 sampled distant from vaccination remained seropositive to at least 1 HPV type (84% to 3 or more types) and 6 (32%) became seronegative (sero-reversion). Those showing sero-reversion had higher VL compared to the 14 who remained seropositive (9100 vs 48; p =0.015). Time from last dose of 4v HPV to sample 4, CD4%, age, gender, and race/ethnicity were similar between the groups. Bar Graphs representing Ab response to the 4 HPV types following each dose of 4v HPV vaccine Conclusion In the complex environment of a pediatric HIV specialty clinic, most PLWH mounted Ab responses to 4v HPV that were durable. H18 was least immunogenic. Patients with higher HIV VL were less likely to seroconvert for all types and were more likely to sero-revert. Disclosures All Authors: No reported disclosures
