A study by Spanish researchers coordinated by CEU San Pablo University has analyzed the factors associated with poor prognosis in case of influenza infection. After analyzing data on 48,000 patients from 135 investigations in 28 countries, they conclude that bacterial superinfections increase the risk of death 3.4 times. The authors propose to increase early diagnostic measures so that antibiotics can be administered quickly in cases where there is a higher risk of complications. The results are published in the International Journal of Infectious Diseases.
A study published in the journal Science Translational Medicine shows the results of a phase 1 trial of a new broad-spectrum influenza vaccine. Prepared in the form of nanoparticles containing the H1 hemagglutinin stem-a region that is often conserved in different subtypes of the virus-the vaccine was generally well tolerated by participants, who showed only mild side effects such as tenderness and headaches. The prototype generated an antibody response to group 1 influenza viruses in all age groups.
A study published in the journal Science reports preclinical results of a new vaccine model that is intended to work against all types of influenza. The prototype, which uses mRNA-based technology, includes antigens from all 20 known influenza subtypes.
