As at-risk Americans stand in long lines across the country, trying to get the Jynneos monkeypox vaccine, U.S. officials on Tuesday announced they will modify dosing instructions for the shot to help stretch the supply.
The U.S. Food and Drug Administration said that instead of sticking with a standard subcutaneous injection, which would enter deep into tissue, the new regimen will be given just under the skin (intradermally) and at one-fifth the usual dose.
“This will increase the total number of doses available for use by up to five-fold,” the agency said in a statement.
