Antibodies induced by mRNA COVID-19 vaccines keep improving in quality for at least six months while the immune system continues to “train” its antibody-producing B cells, according to a new study. In other research, dysfunctional red blood cells contribute to the blood vessel injuries common in severe COVID-19, according to laboratory studies that also may suggest a way to treat the problem.
The U.S. government will make 400 million non-surgical N95 masks from its strategic national stockpile available for free to the public starting next week, a White House official said, marking the Biden administration’s latest effort to help curb the COVID-19 pandemic.
The U.S. Centers for Disease Control and Prevention (CDC) has said Americans should wear the most protective mask they can, but stopped short of recommending an N95 or similar face covering.
