Waning immunity after acellular pertussis (aP) vaccines shown in pertussis outbreaks highlights the need for more effective aP vaccines.
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.
Intramuscular (IM) injection of benzathine benzylpenicillin G (BPG) forms the cornerstone of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) secondary prophylaxis. BPG is available as either a low-cost powdered formulation or a costlier pre-filled suspension. Most of the global RHD burden lies in low- and middle-income countries, which rely on the powdered formulation.
As we finalised our analysis of the adoption of mandatory policies for childhood vaccines in four high-income jurisdictions for our publication, “Convergence on Coercion,” every country on earth was grappling with how to drive uptake of COVID-19 vaccines.
Pneumococcal conjugate vaccine (PCV) prevents pneumococcal disease and pneumonia, but indirect effects are poorly understood in low-coverage, high-burden settings like Papua New Guinea (PNG). PNG introduced 13-valent PCV (PCV13) in 2014. We aimed to assess direct and indirect effectiveness of PCV13 against vaccine-type pneumococcal carriage among children with pneumonia or suspected meningitis in PNG
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.
Vaccination scholarship focuses on how privilege, individualized choice and ‘intensive’ and ‘natural’ parenthood – often motherhood – lead people to delay or not vaccinate their children. Recently, examining parents’ vaccination responsibilities – and the inequalities in paid employment and unpaid care work underpinning them – has become important to understand COVID-19.
Australia commenced administration of the Spikevax (Moderna mRNA-1273) COVID-19 vaccine in August 2021 and Nuvaxovid (Novavax NVX-CoV2373) in January 2022. This study describes the short-term safety profile of priming doses of the Spikevax and Nuvaxovid vaccines given between September 2021 and September 2023.
Meningococcal serogroup B (MenB) strains are highly diverse. Breadth of immune response for the MenB vaccine, 4CMenB, administered at 0-2, 0-6, or 0-2-6 months, was demonstrated by endogenous complement-human serum bactericidal antibody (enc-hSBA) assay against an epidemiologically relevant panel of 110 MenB strains.
Knowledge gaps regarding human immunity to Streptococcus pyogenes have impeded vaccine development. To address these gaps and evaluate vaccine candidates, we established a human challenge model of S. pyogenes pharyngitis. Here, we analyse antibody responses in serum and saliva against 19 antigens to identify characteristics distinguishing 19 participants who developed pharyngitis and 6 who did not.
