Optimal timing of influenza vaccination in patients with human immunodeficiency virus: A Markov cohort model based on serial study participant hemoagglutination inhibition titers

Our results support a policy of administering the seasonal influenza vaccination for this population in the middle of November or beginning of December, assuming nothing is know about the upcoming flu season. But because the difference in between this strategy and the CDC guideline is small-12 deaths averted per year and a savings of $60 million across the HIV+ population in the US-more research is needed concerning strategies for subpopulations.
