Flucelvax Quadrivalent is a subunit influenza vaccine manufactured using cell derived candidate vaccine viruses; it does not contain egg proteins or antibiotics.
Researchers compared safety, reactogenicity, and changes in Health-Related Quality of Life scores of aIIV3 vs HD-IIV3 flu vaccines in older adults.
Researchers analyzed pooled patient data from 2 hospital-based respiratory virus surveillance cohorts to assess the burden of noninfluenza respiratory virus (NIRV) infection.
Researchers compared respiratory viral infections other than severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2020 to corresponding periods in the previous 5 years.
In December 2020, researchers conducted a survey of 1027 adults to determine percentage of those receiving, or intending to receive, influenza vaccination.
The objective of this quasi-experimental observational study was to measure the effect of states’ hospital worker influenza vaccination laws on pneumonia and influenza mortality.
Study authors evaluated influenza-vaccinated patients hospitalized with an influenza-like illness to identify characteristics associated with being at increased risk for hospitalization with influenza.
The AS03-adjuvanted H1N1 influenza vaccine was linked to an increased narcolepsy incidence, but this narcolepsy did not clinically differ significantly from sporadic cases.
There may be increased hospitalization risk from influenza infection in patients with obstructive sleep apnea who do not use continuous positive airway pressure.
