Key ResultWe randomized 115 children to trivalent inactivated influenza vaccine (TIV) or placebo. Over the following 9 months, TIV recipients had an increased risk of virologically-confirmed non-influenza infections (relative risk: 4.40; 95% confidence interval: 1.31-14.8). Being protected against influenza, TIV recipients may lack temporary non-specific immunity that protected against other respiratory viruses.

Seasonal TIV prevented pandemic influenza A(H1N1) and influenza B infections in children and the potential mechanism for seasonal TIV to provide protection, possibly short lived, for children against pandemic A( H1n1) infection despite poor cross-reactive serologic response deserves further investigation.

Influenza-like Illness Incidence Is Not Reduced by Influenza Vaccination in a Cohort of Older Adults, Despite Effectively Reducing Laboratory-Confirmed Influenza Virus Infections

Summary Influenza virus is responsible for 18.2%–33.3% of community-dwelling older adult influenza-like illness (ILI) cases in 2 consecutive seasons. Although vaccination protects against influenza

The effect of influenza vaccination on trained immunity: impact on COVID-19

It is demonstrated that the quadrivalent inactivated influenza vaccine used in the Netherlands in the 2019-2020 influenza season can induce a trained immunity response, including an improvement of cytokine responses after stimulation of human immune cells with SARS-CoV-2, and argued for a beneficial effect of influenza vaccination against influenza as well as COVID-19.

Effect of influenza vaccine on COVID-19 mortality: a retrospective study

Flu vaccination could reduce the mortality of COVID-19, a pandemic infection with high mortality in older patients due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Virus interference and estimates of influenza vaccine effectiveness from test-negative studies.

In a separate placebo-controlled trial of influenza vaccination, it was reported that recipients of influenza vaccine had significantly higher risk of noninfluenza respiratory virus infections, which is consistent with temporary nonspecific immunity.
