Johns Hopkins Medicine researchers have shown that people 60 years or older with weakened immunity -- primarily organ transplant recipients who take immunosuppressive medications to reduce the risk of rejection and others with immune system disorders -- do not respond as strongly to vaccines against the respiratory syncytial virus (RSV) as people in the same age group with normal immune function.
The study, conducted by a research team at the Johns Hopkins Transplant Research Center, was published January 2, 2025, in the Journal of the American Medical Association (JAMA). It parallels earlier work done at the center to better understand how the immune systems of people who are immunocompromised respond to vaccines against SARS-CoV-2, the virus that causes COVID-19.
