Effectiveness of respiratory syncytial virus immunisation in practice.

Respiratory syncytial virus (RSV) affects all ages, with infants and older adults most affected by severe disease. The RSV prevention landscape includes 39 candidates in clinical development, alongside setbacks such as the discontinuation of a promising paediatric live-attenuated vaccine candidate. Several products hav...

Antimicrobial resistance trends and lineage distribution among invasive pneumococcal disease isolates pre- and post-pneumococcal conjugate vaccine introduction, South Africa.

OBJECTIVES Pneumococcal conjugate vaccines (PCV) have reduced antimicrobial-resistant invasive pneumococcal disease (IPD) globally. We evaluated trends in antimicrobial-resistant IPD and pneumococcal lineages before and after PCV13 introduction in South Africa. METHODS We analysed national, laboratory-based IPD surve...

High Mortality in Adults With Community-Acquired Pneumonia Admitted to Hospitals in South Africa Before and During the COVID-19 Pandemic, Stratified by HIV Serostatus and Viral Load: Data From a Prospective Cohort Study (2019–2021)

In-hospital and postdischarge community-acquired pneumonia mortality remains high, particularly among PWH, regardless of virologic status, warranting urgent investigation of mitigation strategies.

Transmission of mutated SARS-CoV-2 variants is favored by relatively prolonged infections due to delayed immunity

SARS-CoV-2 evolution enhanced viral fitness and immune evasion, extending the COVID-19 pandemic and resulting in millions of excess deaths. Viral diversity is generated within infected individuals, yet the timing and interplay of viral and immunological forces that drive transmissible evolution are incompletely underst...
