Antibody response after a single dose of an AS03-adjuvanted split-virion influenza A (H1N1) vaccine in heart transplant recipients.

Background: Influenza A (H1N1) has emerged as a considerable threat for recipients of organ transplants. Vaccination against the novel influenza A (H1N1) virus has generally been advocated. There is limited experience with AS03-adjuvanted A/H1N1 pandemic influenza vaccines in immunosuppressed patients.

Asymptomatic infection with novel influenza A/H1N1 virus in a heart transplant recipient.

The spectrum of manifestations and management of the novel influenza A/H1N1 virus in transplanted patients is currently of major concern. Asymptomatic infections are less common yet important for spreading of the virus and thus affect containment measures. To our knowledge, there are no reports of asymptomatic infections with influenza A/H1N1 in immunosuppressed patients.
