Vaccine hesitancy and suboptimal vaccine uptake pose significant threats to public health, but modifiable psychological factors underpinning them are under-investigated. We examined the prevalence of spontaneous emotional mental imagery relating to infectious diseases and perinatal vaccines and its unique associations with vaccine hesitancy and uptake behaviour.
This study adapts the Multiple Streams Framework (MSF) to explore why COVID-19 vaccine mandates were applied at sectoral and subnational levels in Vietnam while the central government maintained that vaccination was voluntary. Document analysis reveals that these mandates arose from the effective coupling of the three streams—problem, policy, and politics—in a setting of authoritarian rule, where the streams function differently (and more uniformly) compared to democratic contexts.
Protection of newborns from infection can be achieved through maternal or vaccine-induced antibodies, but the factors influencing vaccine protection (correlate of protection) and subsequent infant immunity remain insufficiently understood. Further investigation is essential to optimize early-life vaccination strategies.
A birth acellular pertussis vaccine may be a valuable alternative for immunity against infant pertussis when a pregnancy pertussis vaccine has not been administered. We assessed whether a birth dose may impair immunoglobulin G (IgG) responses to childhood pertussis boosters.
Fear of severe adverse reaction (SAR) and reluctance of health care providers to administer intramuscular injections are major contributing factors to poor adherence of benzathine penicillin G (BPG) in the management of rheumatic heart disease (RHD). However, data on the risk of SARs following BPG injections for RHD are relatively limited and inconclusive. Our systematic review and meta-analysis aimed to evaluate the incidence of SARs associated with BPG injections used for secondary prophylaxis of RHD.
Acute rheumatic fever is a preventable condition that can lead to chronic illness and early death. Standard prevention with 4-weekly intramuscular (IM) benzathine penicillin G (BPG) injections for ≥10 years may be associated with poor adherence. High-dose 10-weekly subcutaneous penicillin injections (SCIP) may improve adherence by reducing injection frequency.
This phase 1 trial assessed the safety and immunogenicity of an investigational tetanus/diphtheria/acellular pertussis vaccine combined with CpG 1018 adjuvant 1500 μg (Tdap-1018 1500 μg) or 3000 μg (Tdap-1018 3000 μg) in adults and adolescents.
As COVID-19 vaccinations rolled out globally from late 2020, rules and recommendations regarding vaccine use in pregnancy shifted rapidly. Pre-registration COVID-19 vaccine trials excluded those who were pregnant. Initial Australian medical advice did not routinely recommend COVID-19 vaccines in pregnancy, due to limited safety data and little perceived risk of local transmission.
Community perception of vaccine safety influences vaccine uptake. Our objective was to assess current vaccine safety monitoring by examining factors that may influence the availability of post-vaccination survey data, and thereby the specificity and sensitivity of existing signal detection methods.
A retrospective study will review episodes of anaphylaxis during bee venom immunotherapy in children, any modifications made to the dosing schedule, and the subsequent outcomes over a nine-year period in Western Australia.
