Tuberculosis disease intensifies HIV antibody response in people with HIV
New research from Boston Medical Center found that people living with HIV that have had pulmonary tuberculosis had broader and more potent HIV antibody responses and differences in HIV sequences predicted to be antibody resistant as compared to those without suspected or documented tuberculosis.
Study offers insights into how COVID variants escape immune system ‘killers’
Omicron subvariants of SARS-CoV-2 — the virus behind COVID-19 — have shown an uncanny knack for evading antibodies produced either by vaccines or exposure to earlier versions of the virus, leading to many breakthrough infections. However, in order to sicken people, these viral variants must also avoid “killer” T cells, immune cells that are unleashed when the immune system detects foreign pathogens.
COVID-19 vaccine elicits weak antibody response in people taking immunosuppressant
People taking TNF inhibitors, a kind of immunosuppressive drug used to treat rheumatoid arthritis and other autoimmune conditions, produced a weaker and shorter-lived antibody response after two doses of Pfizer’s COVID-19 vaccine, according to a study from Washington University School of Medicine in St. Louis. A third vaccine dose drove antibody levels back up, indicating that this additional dose may provide protection as the virus’s delta variant continues to spread.
Story Tips from Johns Hopkins Experts on COVID-19
One year ago, then 65-year-old Miriam Clark developed a fever, lost her appetite and had no energy. She and her daughter, Tye Clark, the administrative services manager of the Johns Hopkins University School of Medicine Division of Hospital Medicine, never could have imagined what they would end up going through before Miriam was diagnosed with COVID-19. Looking back on the year, the mother and daughter duo are thankful and now even have reason to celebrate.
COVID-19 vaccine creates incentive to improve our health
While we wait for our turn to get vaccinated against SARS-CoV-2, we could – and probably should – use the time to make sure we bring our healthiest emotional and physical selves to the treatment, a new review of previous research suggests.
Pre-existing influenza immunity impacts antibody quality following seasonal infection and vaccination
New research by scientists at the University of Chicago suggests a person’s antibody response to influenza viruses is dramatically shaped by their pre-existing immunity, and that the quality of this response differs in individuals who are vaccinated or naturally infected. Their results highlight the importance of receiving the annual flu vaccine to induce the most protective immune response.
Patients Who Had More Severe Covid-19 May Be the Best Donors for Convalescent Plasma Therapy
Sex, age, and severity of disease may be useful in identifying COVID-19 survivors who are likely to have high levels of antibodies that can protect against the disease.
