Covid-19 antibodies passed from infected mothers to their breastfeeding newborns provide more benefit to the baby than researchers expected to see, according to a report published on November 3 in JAMA Network Open.

The Delta variant of the coronavirus does not appear to cause more severe disease in children than earlier forms of the virus, a UK study suggests. Another study found that in Covid-19 survivors, important components of the body’s immune response called memory B cells continue to evolve and get stronger for at least several months, producing highly potent antibodies that can neutralize new variants of the virus.
The U.S. Food and Drug Administration Antimicrobial Drugs Advisory Committee (AMDAC) voted unanimously to recommend use of Takeda Pharmaceutical Company Limited’s maribavir (TAK-620) for the treatment of refractory cytomegalovirus (CMV) infection and disease withgenotypic resistance to ganciclovir, valganciclovir, foscarnet or cidofovir in transplant recipients.
