Flucelvax Quadrivalent Approval Expanded to Include Younger Patients

Brian Park, PharmD

Flucelvax Quadrivalent is a subunit influenza vaccine manufactured using cell derived candidate vaccine viruses; it does not contain egg proteins or antibiotics.

Trivalent Adjuvanted, High-Dose Inactivated Influenza Vaccines Safe for Older Adults

Jessica Nye, PhD

Researchers compared safety, reactogenicity, and changes in Health-Related Quality of Life scores of aIIV3 vs HD-IIV3 flu vaccines in older adults.

Burden of Noninfluenza Respiratory Virus Infection Considerable

Researchers analyzed pooled patient data from 2 hospital-based respiratory virus surveillance cohorts to assess the burden of noninfluenza respiratory virus (NIRV) infection.

COVID-19 Precautions Cut Transmission of Other Common Viruses

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.

Flu Vaccine Rate Expected to Reach All-Time High for 2020-2021 Season

In December 2020, researchers conducted a survey of 1027 adults to determine percentage of those receiving, or intending to receive, influenza vaccination.

The best way to prevent illness against the flu is to remind patients to get vaccinated each year. Those who are aged six months and older should be vaccinated to prevent spreading it to others.

Laws Encouraging Hospital Workers to Vaccinate Reduce Influenza Mortality Rates

Jessica Nye, PhD

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.

Increasing Age, Immunosuppression Associated With Less Protection By Influenza Vaccine

Jessica Nye, PhD

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.

AS03-Adjuvanted Flu Vaccine Increases Narcolepsy Incidence, Clinically Similar to Sporadic Cases

Brandon May

The AS03-adjuvanted H1N1 influenza vaccine was linked to an increased narcolepsy incidence, but this narcolepsy did not clinically differ significantly from sporadic cases.

Untreated Obstructive Sleep Apnea Linked to More Influenza Hospitalizations

Melissa I. Alvarez

There may be increased hospitalization risk from influenza infection in patients with obstructive sleep apnea who do not use continuous positive airway pressure.

Mortality Rates for Pneumonia and Influenza Vary by Geographical Area

Estie Mermelstein, MSN, FNP-BC

Researchers assessed whether there was geographic variation in racial disparity in influenza and pneumonia.

Nosocomial Influenza Outbreak Investigation Informed by Genomic Analyses

Bradley van Paridon

Investigators used precision surveillance by combining genomic sequencing and conventional surveillance to delineate a nosocomial viral outbreak; they believe the findings of their study are applicable to a range of respiratory pathogens, including SARS-CoV-2.
