Chronic medical conditions associated with invasive pneumococcal diseases in inpatients in teaching hospitals in São Paulo city: Estimating antimicrobial susceptibility and serotype-coverage of pneumococcal vaccines.

Background: Chronic conditions increase the risk of invasive pneumococcal diseases (IPD). Pneumococcal vaccination remarkably reduced IPD morbimortality in vulnerable populations. In Brazil, pneumococcal vaccines are included in the National Immunization Program (PNI): PCV10 for < 2 years-old, and PPV23 for high risk-patients aged ≥ 2 years and institutionalized ≥ 60 years.

HPV vaccination programs in LMIC: is it time to optimize schedules and recommendations?

Objectives: Prophylactic HPV vaccines are a fundamental tool to reduce infections and tumors caused by the most prevalent types of these viruses, as this review points out. Several countries have adopted immunization programs that recommend vaccination against HPV for girls and adolescents between 9 and 14 years of age and, in some of them, also for boys. The programs also contemplate the immunization of adults, particularly in the case of individuals with different immunodeficiencies.

Expert review of global real-world data on COVID-19 vaccine booster effectiveness and safety during the omicron-dominant phase of the pandemic.

Introduction: COVID-19 vaccines have been highly effective in reducing morbidity and mortality during the pandemic. However, the emergence of the Omicron variant and subvariants as the globally dominant strains have raised doubts about the effectiveness of currently available vaccines and prompted debate about potential future vaccination strategies.

Areas Covered: Using the publicly available IVAC VIEW-hub platform, we reviewed 52 studies on vaccine effectiveness (VE) after booster vaccinations.
