Transcriptional and Immunologic Correlates of Response to Pandemic Influenza Vaccine in Aviremic, HIV-Infected Children.

Front Immunol 2021 25;12:639358. Epub 2021 Mar 25.

Department of Microbiology and Immunology, University of Miami Miller School of Medicine, Miami, FL, United States.

People living with HIV (PWH) often exhibit poor responses to influenza vaccination despite effective combination anti-retroviral (ART) mediated viral suppression. There exists a paucity of data in identifying immune correlates of influenza vaccine response in context of HIV infection that would be useful in improving its efficacy in PWH, especially in younger individuals. Transcriptomic data were obtained by microarray from whole blood isolated from aviremic pediatric and adolescent HIV-infected individuals (4-25 yrs) given two doses of Novartis/H1N1 09 vaccine during the pandemic H1N1 influenza outbreak.

Potential problem of the co-occurrence of pandemic COVID-19 and seasonal influenza.

Epidemiol Mikrobiol Imunol 2021 ;70(1):68-71

In times of COVID-19 pandemics, the upcoming period of the year when influenza activity usually increases in the Northern Hemisphere brings new medical and public health challenges. These challenges include the risk of mixed infections and/or a possible collision of the two epidemics (“twindemia”) with a potentially serious impact on individual health and public health. In this report, we discuss the results of the published stu-dies and conclude that the catastrophic collision of the seasonal influenza and COVID-19 epidemics is unlikely when efficient non-pharmaceutical public health measures are applied to control or mitigate the spread of the COVID-19 epidemic.
