Reopening to the world: how safety, normality and trust in government shape young adults’ COVID-19 vaccine intentions

During the COVID-19 pandemic, and particularly 2020-2021, young adults were often significant transmitters of the virus. Prior to the availability of vaccines for young adults, we sought to understand what would contribute to their uptake of a COVID-19 vaccine and how government policy might intervene. We undertook qualitative interviews between February and April 2021 with 19 participants (aged 18-29) in Perth, Western Australia.

A phase III, multicenter, randomized, double-blind, active comparator-controlled study to evaluate the safety, tolerability, and immunogenicity of catch-up vaccination regimens of V114, a 15-valent pneumococcal conjugate vaccine(PNEU-PLAN)

Despite widespread use of pneumococcal conjugate vaccines (PCVs) in children, morbidity and mortality caused by pneumococcal disease (PD) remain high. In addition, many children do not complete their PCV course on schedule. V114 is a 15-valent PCV that contains two epidemiologically important serotypes, 22F and 33F, in addition to the 13 serotypes present in PCV13, the licensed 13-valent PCV.

A Systematic Framework for Prioritizing Burden of Disease Data Required for Vaccine Development and Implementation: The Case for Group A Streptococcal Diseases

Vaccine development and implementation decisions need to be guided by accurate and robust burden of disease data. We developed an innovative systematic framework outlining the properties of such data that are needed to advance vaccine development and evaluation, and prioritize research and surveillance activities.

Automated reporting of primaquine dose efficacy, tolerability and safety for Plasmodium vivax malaria using a systematic review and individual patient data meta-analysis

The antirelapse efficacy of primaquine is related to the total dose administered, whereas the risks of haemolysis and gastrointestinal intolerance are associated with the daily dose administered. National Malaria Control Programmes require local information on efficacy, tolerability and safety to optimize antimalarial treatment policies for Plasmodium vivax malaria control and elimination efforts.

The impact of obesity on influenza Vaccine immunogenicity - A systematic review

Influenza vaccines are important for reducing the burden of influenza, particularly for populations at risk of more severe infections. Obesity is associated with increased influenza severity and therefore individuals with obesity are often specifically recommended for annual influenza vaccination. Obesity is also associated with an altered inflammatory profile, which may influence vaccine responses. This systematic review aimed to evaluate the evidence for any association between obesity and influenza vaccine immunogenicity.

Subcutaneous Infusion of Benzathine Penicillin G Is Acceptable and Preferred Over Intramuscular Injections for Syphilis in Western Australian Sexual Health Clinic Attendees

Controlling the syphilis epidemic in Australia is a public health priority. Regular intramuscular (IM) injections of benzathine penicillin G (BPG) are the current standard of care for late latent syphilis in Australia; however, repeated IM BPG injections are painful, and treatment completion rates are low. Early-phase clinical trials have demonstrated the tolerability and safety of high-dose subcutaneous infusions of BPG (SCIP), where the total treatment dose can be delivered at a single visit. Here we describe the experiences and preferences of attendees of Western Australian sexual health clinics in the Perth metropolitan region who have syphilis and were treated with SCIP.

Acute rheumatic fever

Acute rheumatic fever is an autoimmune disorder resulting from Group A Streptococcus pharyngitis or impetigo in children and adolescents, which may evolve to rheumatic heart disease (RHD) with persistent cardiac valve damage. RHD causes substantial mortality and morbidity globally, predominantly among socioeconomically disadvantaged populations, with an interplay of social determinants of health and genetic factors determining overall risk.

Serological Responses to Target Streptococcus pyogenes Vaccine Antigens in Patients With Proven Invasive β-Hemolytic Streptococcal Infections

Rising incidence of invasive β-hemolytic streptococcal (iBHS) infections has prompted consideration of vaccination as a preventative strategy for at-risk populations. The benefits of a vaccine targeting Lancefield group A (Streptococcus pyogenes; Strep A) would increase if cross-species immunity against Lancefield groups C/G (Streptococcus dysgalactiae subspecies equisimilis; SDSE) and B (Streptococcus agalactiae; GBS) was demonstrated.

Immunogenicity, Reactogenicity, and Safety of a Pentavalent Meningococcal ABCWY Vaccine in Adolescents and Young Adults who had Previously Received a Meningococcal ACWY Vaccine

A MenABCWY vaccine containing 4CMenB and MenACWY-CRM vaccine components has been developed to protect against the 5 meningococcal serogroups that cause most invasive disease cases.
