Mil­lions more mon­key­pox vac­cine and an­tivi­ral cours­es com­ing to states next week, but will it be enough?

HHS said this morn­ing that be­gin­ning next Mon­day it will make avail­able an ad­di­tion­al 1.8 mil­lion in­tra­der­mal dos­es (5 dos­es per vial) of Bavar­i­an Nordic’s Jyn­neos vac­cine, al­though on­ly states and oth­er ju­ris­dic­tions that have used up 90% of their cur­rent sup­plies can ob­tain the new dos­es.

The push for more dos­es and the switch to in­tra­der­mal dos­es comes as top FDA lead­ers wrote to Bavar­i­an Nordic last week say­ing that the avail­able vac­cine dos­es through the end of this year “is es­ti­mat­ed to on­ly be suf­fi­cient to im­mu­nize half of the in­di­vid­u­als at high­est risk for mon­key­pox.” FDA com­mis­sion­er Rob Califf and CBER di­rec­tor Pe­ter Marks al­so wrote that they’ve ruled out us­ing any oth­er vac­cines at the mo­ment, but not­ed that the in­tra­der­mal ap­proach with Jyn­neos “pro­duced a very sim­i­lar im­mune re­sponse to sub­cu­ta­neous ad­min­is­tra­tion.”
