The CDC is sending monkeypox vaccines to people at high risk in a race to prevent the spread

The Biden administration has distributed 1,200 monkeypox vaccine doses for people who have had high-risk exposures to the virus, part of a nationwide public health response to stamp out the disease before it causes a major outbreak.

U.S. health officials, worried the virus is spreading faster than previously thought, have said the global outbreak of monkeypox is the largest ever. The World Health Organization said Wednesday that there are now more than 550 cases across 30 countries. In the U.S., at least 20 confirmed or suspected cases have been reported in 11 states, including California, Colorado, Florida, Georgia, Illinois, Massachusetts, New York, Pennsylvania, Virginia, Utah and Washington state, according to the Centers for Disease Control and Prevention.

Last week, CDC official Dr. Jennifer McQuiston said the U.S. has 1,000 doses of Jynneos available. However, the Danish biotech company that makes the shots, Bavarian Nordic, said the U.S. actually has a supply of more than 1 million Jynneos frozen doses stored in the U.S. and Denmark under an order placed in April 2020. The shots have a shelf life of three years.

The U.S. government also has a stockpile of more than 100 million doses of ACAM2000, made by Emergent BioSolutions, McQuiston told reporters last week. The U.S. had released 500 doses of Jynneos and 200 doses of ACAM2000 as of Tuesday, according to the CDC. The U.S. has also sent out 100 courses of the oral antiviral tecovirimat to the states, health officials said Friday.

The CDC has said women who are pregnant or breast feeding, people with weak immune systems, those with skin conditions such as eczema or atopic dermatitis, and people with heart disease should not receive ACAM2000. In pregnant women, the virus can spread to the fetus and cause stillbirth. People with weak immune systems face a risk that the virus will grow uncontrollably and cause a dangerous infection, Slifka said. People with skin conditions such as eczema or atopic dermatitis are also at risk of the virus spreading on their skin which can turn into a life-threatening infection, he said.

Lewis said the WHO is not recommending mass vaccination against monkeypox because the current outbreak can still be contained. Most of the cases so far have been reported among men who have sex with men, developed symptoms and sought care at sexual health clinics, according to the WHO. Lewis said it is important to provide gay and bisexual men with the information they need to protect themselves from the virus and prevent it from spreading.

Monkeypox typically starts with symptoms similar to the flu including fever, headache, muscle aches, chills, exhaustion and swollen lymph nodes. Lesions then form on the body, and the virus spreads primarily through skin-to-skin contact with these lesions. Monkeypox can spread through respiratory droplets [not again!] if a person has lesions in their throat or mouth, but it does not transmit easily this way.
