Why It&039;s So Hard to Get a Monkeypox Vaccine Right Now
the country has enough vaccines in the Strategic National Stockpile . But many of the stockpiled ones are the older ACAM2000 vaccine, which is approved for use against smallpox and can also be used for monkeypox. It’s a live virus vaccine containing a virus that’s related to smallpox but milder. The shot causes a temporary sore at the injection site, which—if not properly cared for—can potentially spread the virus to unvaccinated people in close contact.
During a July 15 press briefing, U.S. Centers for Disease Control and Prevention Director Dr. Rochelle Walensky acknowledged that vaccine shortages are “frustrating” but said the administration is actively working to increase supply. Federal health officials will send more doses to jurisdictions that are seeing rising case rates, she said. New York, California, Illinois, Florida, Georgia, and Washington D.C.
But inadequate contact tracing and testing has made it hard to identify those who are infected and exposed, says Andrew Kilianski, an emerging infectious disease expert and adjunct professor at George Mason University. National testing capacity has increased from about 6,000 tests per week early in the outbreak to 70,000 now, according to federal health officials, but Kilianski says screening is still inadequate.
