There’s presently no alternative for Evusheld. Dr. Ashish Jha, head of the White Home Covid job drive, has blamed Congress for the dwindling variety of remedies. He mentioned lawmakers’ failure to cross further Covid funding means there is not cash to spend money on new antibodies.

“We had hoped that over time because the pandemic went alongside, as our struggle towards this virus went alongside, we might be increasing our medication cupboard,” Jha advised reporters in October. “Due to lack of congressional funding, that drugs cupboard has really shrunk and that does put weak individuals in danger.”
