Critique: U.S. to Vaccinate 500,000 Workers Against Smallpox
Dr. Meryl Nass
An estimated 500,000 first responders, lab and hospital workers will receive smallpox vaccine, the DHHS announced yesterday.
This is an interesting announcement, because to my knowledge there exist no FDA-licensed smallpox vaccines.
There are three vaccine candidates whose safety and efficacy are uncertain at this time.
The first vaccine made available was Wyeth’s Dryvax, which was pulled out of storage after approximately thirty years.
