Vaccine-induced immune response to omicron wanes substantially over time

A new clinical trial found that COVID-19 booster vaccinations in adults elicit high levels of neutralizing antibodies against the Omicron variant, but these antibody levels decrease substantially within 3 months. The immune response to Omicron sub-lineages shows reduced susceptibility to rapidly emerging variants.

Hyperimmune intravenous immunoglobulin does not improve outcomes for adults hospitalized with COVID-19

A clinical trial found that combining remdesivir with hyperimmune intravenous immunoglobulin did not improve health status or safety for adults hospitalized with COVID-19. The trial also showed a higher risk of adverse outcomes among patients who generated SARS-CoV-2-neutralizing antibodies before treatment.

Too many people with HIV fail to achieve durable viral suppression

According to a new study funded by NIH, adults with HIV are making progress toward the global target of 95% viral suppression, but children and adolescents are not. The researchers estimated that among adults, 79% were virally suppressed after one year of treatment, while among children and adolescents, only 64% reached this milestone.

Gene therapy restores immune function in children with rare immunodeficiency

Infants and children with ADA-SCID, a life-threatening inherited immunodeficiency disorder, have regained immune system function after receiving gene therapy. The treatment involves inserting a normal copy of the ADA gene into blood-forming stem cells, offering a one-time procedure with long-term benefits.
