Reductions in all-cause otitis media (OM) following widespread pneumococcal conjugate vaccine use have plateaued. Granular burden of disease data are needed to guide evaluation and implementation of new measures targeting OM prevention. We conducted a retrospective study to assess the incidence and treatment costs of OM, tympanostomy tube placement (TTP), and hearing loss in children aged <5 years in the United States (US).

Background: The number of patients with skin and soft tissue infections (SSTIs) in the United States appeared to be increasing well into the 21st century. However, no recent data have confirmed this trend.

Methods: This retrospective, observational cohort study used claims data over 11 years (2010-2020) from Optum's de-identified Clinformatics Data Mart Database.

Otitis media (OM) is a common disease of childhood and available pneumococcal conjugate vaccines (PCVs), with different compositions, could have different impact on OM reduction. This systematic literature review evaluated available data describing the efficacy, effectiveness, and impact of 10-valent pneumococcal protein D conjugate vaccine (PHiD-CV) and 13-valent PCV (PCV13) on OM outcomes. Statistically significant reductions in all-cause and complicated OM, tympanostomy tube placement and OM-related hospitalizations were consistently observed after the introduction of PHiD-CV and PCV13.

In Russia, a universal varicella vaccination (UVV) program has not been implemented, and varicella vaccination coverage is low. We assessed the efficacy, antibody persistence, and safety of one- and two-dose varicella vaccination schedules in Russian children with a ten-year follow-up period, as part of an international phase IIIB, observer-blind, randomized, controlled trial (NCT00226499). Children aged 12-22 months were randomized (3:3:1) to receive two doses of tetravalent measles-mumps-rubella-varicella vaccine (V2 group), one dose trivalent measles-mumps-rubella (MMR) vaccine and one dose of varicella vaccine (V1 group), or two doses of MMR vaccine (V0 [control] group), 42 days apart.

Article Synopsis
  • Vaccine immunity against pertussis decreases over time, making adults and adolescents potential transmitters of the disease to infants, which is a concern since Russia doesn't have pertussis vaccines for older groups.
  • A phase III study in Russia evaluated the safety and immune response of the dTpa vaccine in healthy participants aged 4 years and older, showing over 99% protection against diphtheria and tetanus, and over 96% positive for pertussis antibodies after one month.
  • The dTpa booster vaccine induced a strong immune response in all ages tested, with minimal adverse effects reported, indicating it is a safe and effective option for enhancing immunity against diphtheria, tetanus, and pertussis.

We assessed the immunogenicity and safety of the combined diphtheria-tetanus-acellular pertussis-inactivated poliovirus/ type b vaccine (DTPa-IPV/Hib) in children in Russian Federation aiming to support the registration of the vaccine in Russia. In this phase 3, non-randomized, open-label study (NCT02858440), healthy children received three primary doses at 3, 4.5, and 6 months of age (N = 235) and a booster dose at 18 months of age (N = 225).
