Safety monitoring of health outcomes following influenza vaccination during the 2023-2024 season among U.S. Commercially-insured individuals aged 6 months through 64 years: Self-controlled case series analyses.

Background: Influenza vaccines are reformulated annually to target expected virus strains for the upcoming season. Although the safety of seasonal influenza vaccines is well-established, active safety surveillance of reformulated vaccines is essential to assess occurrence of potential health outcomes among vaccinated individuals. This study evaluated the safety of the 2023-2024 influenza vaccines among U.

Safety monitoring of health outcomes following influenza vaccination during the 2023-2024 season among U.S. Medicare beneficiaries aged 65 years and older.

Background: Influenza vaccination is widely recommended for individuals aged 6 months and older in the United States. While the safety of annual influenza vaccines is well established, FDA conducts routine monitoring and safety evaluations. This study assessed the safety of 2023-2024 influenza vaccines among elderly Medicare beneficiaries.

An FcRn-targeted mucosal vaccine against SARS-CoV-2 infection and transmission.

SARS-CoV-2 is primarily transmitted through droplets and airborne aerosols, and in order to prevent infection and reduce viral spread vaccines should elicit protective immunity in the airways. The neonatal Fc receptor (FcRn) transfers IgG across epithelial barriers and can enhance mucosal delivery of antigens. Here we explore FcRn-mediated respiratory delivery of SARS-CoV-2 spike (S).

An FcRn-targeted mucosal vaccine against SARS-CoV-2 infection and transmission.

SARS-CoV-2 and its variants cause COVID-19, which is primarily transmitted through droplets and airborne aerosols. To prevent viral infection and reduce viral spread, vaccine strategies must elicit protective immunity in the airways. FcRn transfers IgG across epithelial barriers; we explore FcRn-mediated respiratory delivery of SARS-CoV-2 spike (S).

FcRn-Targeted Mucosal Vaccination against Influenza Virus Infection.

The respiratory tract is constantly exposed to various airborne pathogens. Most vaccines against respiratory infections are designed for the parenteral routes of administration; consequently, they provide relatively minimal protection in the respiratory tract. A vaccination strategy that aims to induce the protective mucosal immune responses in the airway is urgently needed.
