Correspondence Influenza vaccination and prevention of cardiovascular disease mortality – Authors' reply
We thank Daniel Caldeira, Joaquim J Ferreira, and Jo ão Costa for highlighting the effect of influenza infection on underlying cardiovascular disease and the role of influenza vaccination in potentially mitigating this risk. Although we briefly mentioned that influenza infection could exacerbate underlying cardiovascular disease in our Seminar,1 we w ere unable to fully expand on this point because of word-count restrictions. In this regard, an epidemiological link between influenza and excess deaths associated with cardiovascular disease was suggested as early as in the 1930s.
Conclusions: Patients with nonhematological malignancies who are receiving chemotherapy mount an immune response to influenza vaccination. Timing of influenza vaccination in relation to chemotherapy does not seem to matter.
We report of high influenza B Victoria virus prevalence in the 2015-16 winter season in Israel, affecting approximately half of the Israeli population. We further show that the Victoria B virus infected individuals of all ages and that it was present in the country throughout the entire winter season. The vaccine however included the inappropriate Yamagata virus. We propose that a quadrivalent vaccine, that includes both Yamagata and Victoria lineages, should be considered for future influenza vaccination. PMID: 29464098 [PubMed]
After a two-year hiatus, the nasal flu vaccine is set to return to doctors’ offices next year. The Advisory Committee on Immunization Practices (ACIP) voted 12 to 2 on Wednesday to return the nasal spray to the CDC’s list of recommended vaccines for the 2018-2019 flu season. Pending final approval from the CDC director, the vote would greenlight the spray for widespread use and compel insurance companies to cover it. The committee stopped short of explicitly recommending the nasal spray, however, and will instead let providers and patients decide if they’ll use it instead of traditional flu shots. There ...

Flu vaccinations may become painless again. A US Centers for Disease Control and Prevention advisory committee voted Wednesday to recommend, once again, that FluMist, the nasal spray version of the influenza vaccine, be used during the 2018-19 season.
(Reuters Health) - Infants are much less likely to get influenza or whooping cough when their mothers were vaccinated against these infections during pregnancy, and a new study suggests this doesn ’t pose a safety risk for babies.

A flu shot is recommended for every person older than 6 months in the United States, even though the CDC reported on Thursday that this year's vaccine is only 25 percent effective against H3N2 influenza, the cause of most illness so far this season.
