We reviewed measles surveillance data for 1993–2002 to determine the impact of Australia's measles control initiatives. The introduction of a second dose of measles–mumps–rubella (MMR) vaccine for 10- to 16-year-olds in 1993 was followed by marked reductions in measles notifications and hospitalizations, especially in the targeted age group. Further rate reductions were achieved following the Measles Control Campaign (MCC) in 1998, which involved a catch-up campaign for primary-school-aged children and lowering the age for the second dose of MMR vaccine to 4 years. Since the MCC, outbreaks have continued to occur, but most had a source case who was infected overseas, which suggests that indigenous transmission has been interrupted. In addition, a greater proportion of cases have been in adults although infants aged <5 years still had the highest rates. In conclusion, Australia is making good progress towards measles elimination. However, as in other countries, this progress can be sustained only by maintaining high vaccination coverage with the routine childhood vaccination schedule.

Background: The condition known as 22q11 microdeletion syndrome has a broad phenotypic spectrum, with many affected individuals experiencing mild-to-moderate immunodeficiency. Currently, there are significant variations in live vaccine practices and immunological testing prior to live vaccine administration due to safety concerns and limited established guidelines. Methods: Queensland Children’s Hospital (QCH) Child Development Unit, offers a state-wide 22q11 microdeletion clinic. This is a retrospective single-centre review, capturing the majority of children with 22q11 microdeletion in Queensland, Australia. We describe the live vaccination status of 134 children, age 0 to 18 years under our care between 2000 and 2018, adverse events following immunisation (AEFI) and the proportion of children who received additional pneumococcal coverage. An immunological investigation pathway prior to live vaccine administration is proposed. Results: Of the 134 children, 124 were eligible for live vaccinations as per the Australian National Immunisation Program: 82% had received dose one of measles, mumps and rubella (MMR) vaccine, 77% had completed MMR dose two and 66% had completed varicella immunisation. There were no AEFI notifications reported. Of the total sample of children, 18% received a fourth dose of conjugate pneumococcal vaccine (Prevenar 7 or 13) and 16% received a dose of Pneumovax 23 from 4 years of age. Immunology workup practices were demonstrated to vary widely prior to live vaccine administration. Most patients’ immune profiles were consistent with mild-to-moderate immunodeficiency. Conclusion: We propose an immunological investigation and vaccination pathway with the aim of providing guidance and consistency to clinicians caring for children with 22q11 microdeletion.

Abstract.The Western Pacific Region (WPR) is comprised of 37 countries such as China, Japan, Mongolia, Republic of Korea, The Socialist Republic of Vietnam, Papua-New Guinea, Australia, including Pacific Island Countries and Territories (21 countries of PICTs, approx. 3 million people) etc., with a population of 1.85 billion people. Among them, China is the largest and most populous (1.3 billion people) country of the Region. Large measles outbreaks were documented to occur in the Region. In 2003, the Regional Committee announced officially about the WPR action plan on measles elimination 2005, which, however, failed. Since 2012, WPR countries joined the WHO 2012–2020 Global Measles and Rubella Strategic Plan performing a routine measles vaccination (national immunization schedule) or within Expanded Programme on Immunization (EPI). Basically, a two-dose immunization strategy is followed in the WPR countries. Since 2002, measles supplementary immunization activities (SIAs) in children were conducted in the following countries: Japan, Laos, Vietnam, Philippines, Mongolia, Cambodia, Papua New Guinea, and China. Starting from 2005, measles management was considerably improved, demonstrating by 2012 decreased measles incidence rate down to 5.9 cases per million population. In last years, a decreased measles immunization coverage in decreed population groups was noted in the WPR countries that resulted in 2013–2015 measles epidemic involving almost all regional countries. In particular, in China measles incidence rate was 19.6 cases per million population, whereas in the Vietnam Papua New Guinea and Philippines it progressively increased reaching 182.8, 345.9 and 548.0 cases per million population, respectively. Early children not vaccinated according to schedule, adolescents and young adults dominated among measles patients. It was found that measles outbreaks were due to missed vaccination and increased level of vulnerability to measles. Children under one, adolescents and young adults who did not receive a two-dose measles vaccination were in risk group. Analyzing WPR measles epidemiology demonstrated that refusal of parents to vaccinate children, poor knowledge of advantages related to vaccination, insufficient immunization coverage in immigrants, travelers, subjects changing place of residence, workers of healthcare and educational facilities require special attention. In 2017–2018 season, the following measles genotypes were found in the WPR: D8 — Australia, New Zealand, Republic of Korea, Singapore, Japan; Н1 — China; В3 — Philippines, Australia and Japan; D9 — Singapore, Australia, Macau (China), Malaysia and Japan, Н2 strains endemic in Vietnam. According to the WHO, measles endemic transmission has been successfully interrupted; Australia, Macau, Mongolia and Republic of Korea are being verified to eliminate measles; Hong Kong (China) and Singapore (based on available information) are ready to verify measles elimination. Thus, in the Western Pacific Region measles elimination is achievable after solving current issues such as increasing and maintaining high-level routine vaccination and conducting measles supplementary immunization campaigns in epidemically important contact clusters.

Full textAbstract:
In the pre-vaccination era, rubella was regarded as only a mild exanthematous acute viral infection of children. The devastating effects of the disease were first identified in the early 1940s by an Australian ophthalmologist, and further confirmed during the 1962-65 rubella pandemic in Europe and the United States. They result from the transmission of the virus by infected pregnant women to their fetus. The resulting congenital rubella syndrome (CRS) comprises a lengthy list of abnormalities. The most common ones are deafness, ocular and cardiac defects and mental retardation. The objective of rubella vaccination, to which France has subscribed, is the elimination of CRS [1].

Abstract Background This study describes trends in social inequities in first dose measles-mumps-rubella (MMR1) vaccination coverage in Western Australia (WA) and New South Wales (NSW). Using probabilistically-linked administrative data for 1.2 million children born between 2002 and 2011, we compared levels and trends in MMR1 vaccination coverage measured at age 24 months by maternal country of birth, Aboriginal status, maternal age at delivery, socio-economic status, and remoteness in two states. Results Vaccination coverage was 3–4% points lower among children of mothers who gave birth before the age of 20 years, mothers born overseas, mothers with an Aboriginal background, and parents with a low socio-economic status compared to children that did not belong to these social groups. In both states, between 2007 and 2011 there was a decline of 2.1% points in MMR1 vaccination coverage for children whose mothers were born overseas. In 2011, WA had lower coverage among the Aboriginal population (89.5%) and children of young mothers (89.3%) compared to NSW (92.2 and 92.1% respectively). Conclusion Despite overall high coverage of MMR1 vaccination, coverage inequalities increased especially for children of mothers born overseas. Strategic immunisation plans and policy interventions are important for equitable vaccination levels. Future policy should target children of mothers born overseas and Aboriginal children.

Full textAbstract:
The Australian Paediatric Surveillance Unit (APSU) has been conducting surveillance of rare communicable and non-communicable conditions in children since its inception in 1993. In this report, the results are described of surveillance of ten communicable diseases (and complications) for 2021, including the numbers of cases and incidence estimates; demographics; clinical features; and management and short-term outcomes. The included diseases are: acute flaccid paralysis (AFP); congenital cytomegalovirus (CMV); neonatal herpes simplex virus (HSV) infection; paediatric human immunodeficiency virus (HIV) infection; perinatal exposure to HIV; severe complications from influenza; juvenile-onset respiratory papillomatosis (JoRRP); congenital rubella syndrome; congenital varicella syndrome; and neonatal varicella infection. In 2021, cases of JoRRP were reported to the APSU for the first time since 2017, indicating potential gaps in HPV vaccination. AFP surveillance by APSU again contributed to Australia achieving a minimum target incidence of one AFP case per 100,000 children aged < 15 years. There were no cases of children with severe complications of influenza. No cases of varicella or congenital rubella were reported; however, at-risk populations, especially young migrant and refugee women from countries without universal vaccination programs, need to be screened and prioritised for vaccination prior to pregnancy. Cases of perinatal exposure to HIV continue to increase; however, the rate of mother-to-child-transmission remains at low levels due to the use of effective intervention strategies. Case numbers of congenital CMV and neonatal HSV remain steady in the absence of vaccines, prompting the need for greater awareness and education, with recent calls for target screening of at-risk infants for congenital CMV.

Objective To describe the use of normal human immunoglobulin (NHIG) recommended for public health purposes in Queensland and Australia. Methods Queensland public health unit (PHU) data on notified cases of measles, rubella and hepatitis A from 2004 to 2014 were examined; particularly regarding the number of contacts offered NHIG and the volume recommended per contact. The National Blood Authority (NBA) provided unidentified data from NHIG order form inception (June 2014) through December 2016. Queensland orders were compared to PHU data where the data timeframes overlapped. Results NHIG usage varied by condition. For hepatitis A, usage declined after the introduction of vaccination for contacts in 2010. Usage fluctuated across the study period for measles and was not recommended for rubella. Average volumes per contact for hepatitis A and measles were 1.6mL and 11.9mL respectively based on PHU data. PHU data approximated NBA data on NHIG usage for hepatitis A and rubella contacts. Calculated volumes of NHIG per measles contact were also similar, but PHU data underestimated the number of measles contacts for whom NHIG was ordered. Discussion This study is the first to document the use of NHIG for public health purposes in Australia. Results will be valuable for national blood sufficiency planning and cost effectiveness studies in the event of alterations to NHIG dosage recommendations.

Full textAbstract:
IntroductionRecipients of solid organ transplants are at risk of serious infection due to immunosuppression. Some infections are preventable with vaccination; infection rates vary with immunosuppression, vaccination rates and baseline disease prevalence. Both adherence with and response to vaccination in this population are variable, and optimum vaccination strategies continue to be refined.
Objectives and ApproachWe aimed to characterise the incidence and complications of vaccine-preventable infections in transplant recipients. Eligible participants received an organ transplant in New South Wales, Australia, in 2000-2015. Linkage was undertaken between transplant registries and the notifiable conditions information management system. Vaccine-preventable infections were diphtheria, Haemophilus influenzae type b, influenza, invasive pneumococcal disease, measles, mumps, pertussis, poliovirus, rubella and tetanus. Standardized incidence ratios (SIR) were calculated relative to Australian population notification rates, standardizing for gender, age and calendar year.
ResultsAmong 3,394 recipients, 399 vaccine-preventable infections affected 339 (10%) recipients. Influenza was the most common vaccine-preventable infection with 352 notifications among 305 recipients. Influenza cases were 8.9 times more common among transplant recipients than the general population (95%CI: 8.0-10.0). In 36 cases (10%), hospitalization was required, and 2 deaths due to influenza were reported.
There were 20 notifications of invasive pneumococcal disease (IPD) for 18 recipients. IPD occurred 10.2 times more often among transplant recipients than the general population (95%CI: 6.4-16.2). Most (n=13, 65%) cases were hospitalized, and one patient died from IPD.
Cases of pertussis occurred only slightly more often than in the general population (SIR 1.5, 95%CI: 1.0-2.3). Of 26 cases, there was one reported hospitalization and no deaths due to pertussis. Only one case of mumps, and no other vaccine-preventable infections, were reported.
ConclusionTransplant recipients have excess cases of influenza and IPD compared to the general population, although this has improved over time. The need for appropriate recipient vaccination is emphasized.

Background In recent years, there have been ongoing outbreaks of mumps reported in Northern and North-Western Queensland, Western Australia and the Northern Territory, Australia. We aimed to define the epidemiology of mumps outbreaks in Central Queensland, Australia between October 2017 and October 2018 and evaluate the effectiveness of an additional dose of measles, mumps, rubella (MMR) vaccine. Methods A retrospective case control study was conducted, including outbreak investigations with laboratory-confirmed cases of mumps and subsequent comparison with matched controls. We analysed mandatory notifications from the Queensland Health Notifiable Conditions System database and immunisation information from the Queensland Health Vaccination Information and Admin System (VIVAS) and the Australian Immunisation Register. Results Between October 2017 and October 2018, there were 93 cases of mumps reported in Central Queensland with three distinct outbreaks: a discrete Indigenous community; a correctional facility; and a boarding school. Among all cases, 74 (79.6%) were fully vaccinated and 14 (15.1%) were partially vaccinated with MMR vaccine. Eighty-six cases (92.5%) were reported among Aboriginal and Torres Strait Islander people. In all outbreaks, an additional dose of MMR vaccine was offered with 35.4%, 73.6% and 35.8% of the target population being immunised in the discrete Indigenous community, the correctional facility and the boarding school, respectively. Prior to this additional dose of MMR, the mumps attack rate was 31.0 (95% confidence interval [95% CI]: 24.2–39.0) per 1000 population, compared to the post-additional dose MMR attack rate of 10.6 (95% CI: 6.7–15.9) per 1000 population. Conclusion An additional or booster dose of MMR should be included as an effective public health intervention strategy, particularly in communal or high-density living conditions to control mumps outbreaks in highly vaccinated populations.

Abstract Background Patients with Inflammatory Bowel Disease (IBD) are at increased risk of serious infections, including vaccine preventable diseases. Current evidence suggests uptake of additional recommended special risk vaccinations is low. Identification of IBD patients prior to commencing immunosuppressive therapy allows for optimisation of vaccination, including timely administration of live-attenuated and additional recommended vaccines, such as influenza and pneumococcal vaccines. Methods Paediatric patients (0–18 years) seen at the tertiary Royal Children’s Hospital, Melbourne, Australia, with a recent diagnosis of IBD were referred by the Gastroenterology Unit to our Specialist Immunisation Clinic (SIC) for assessment and provision of routine and special risk vaccines. Data was collected via a standardised REDCap questionnaire completed in or post attendance at the SIC and included serology results where available. Results Sixty-nine paediatric patients were recruited to the study between 2014 and 2017. Median age at IBD diagnosis was 11.25 years (IQR 4.64 years), with median time between diagnosis and SIC review of 0.88 years (IQR 2.84 years). At initial review 84.1% (58/69) of patients were up to date with vaccines on the Australian National Immunisation Program (NIP) schedule. Of those who were tested, serological evidence of immunity was demonstrated in 38.3% (23/60) of patients for Hepatitis B, 66.7% (36/54) for measles, 51.9% (28/54) for rubella and 41.9% (26/62) for Varicella Zoster Virus. Prior to SIC review 47.8% (33/69) had additional vaccinations and 92.8% (64/69) had vaccinations administered in the 12 months following SIC assessment. The Pneumococcal conjugate vaccine (76.8%, 53/69) was the most commonly administered vaccine after SIC review, followed by influenza vaccine (69.6%, 48/69). Within 12 months of SIC review 43.5% (30/69) of patients had completed the schedule and were up-to-date as recommended by the SIC. Conclusions Children with IBD and other special risk groups can benefit from early referral to a SIC team to ensure optimal administration of routine and additionally recommended vaccines, especially live and additional special risk vaccines. The value of optimising immunisations could also be applied to other special risk groups, including adult IBD cohorts, particularly those commencing newer biologic immunosuppressive medications.

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.

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.
