NEW YORK (AP) — The U.S. is setting aside an extra 50,000 doses of monkeypox vaccine for places with upcoming gay pride events, health officials said Thursday.

The number of doses sent to each place will be based on factors like the size of the event, how many health workers will be available to give shots, and how many of the attendees are considered at highest risk for catching the virus.

“More shots in arms is how we get the outbreak under control,” Bob Fenton, the White House monkeypox response coordinator, told reporters Thursday. He said the effort is an attempt to “meet people where they are.”

At least a dozen U.S. pride events are scheduled over the next two months, including large gatherings in Atlanta and New Orleans in early September. U.S. officials said they will send up to 2,000 additional doses to North Carolina, where the Charlotte Pride Festival & Parade will be held this weekend.

Southern Decadence, one of the nation’s largest LGBTQ events, is expected to attract 200,000 or more people to New Orleans over Labor Day weekend. The Bourbon Street Extravaganza, a free concert held amid the event, has been canceled over monkeypox concerns, organizers said this week.

Frank Perez, a former grand marshal of the parade that’s the centerpiece of Southern Decadence, said a number of New Orleans gay bars have already had vaccine events. He said so far officials have done an adequate job with the vaccine campaign although “more is better.”

Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, cautioned: “While we are offering the vaccine at these events to those at high risk, this is a two-dose vaccine series, and receiving the vaccine at the event will not provide protection at the event itself.”

Health officials also are urging other steps to prevent the spread of the virus, including temporarily limiting sexual partners.

Monkeypox is endemic in parts of Africa, where people have been infected through bites from rodents or small animals, but it wasn’t considered a disease that spreads easily among people until May, when infections emerged in Europe and the U.S.

There have been more than 39,000 cases reported in countries that have not historically seen monkeypox. The vast majority have occurred in men who have sex with men, but health officials stress that anyone can get monkeypox.

The U.S. has the most infections of any country — more than 13,500. About 98% of U.S. cases are men and about 93% were men who reported recent sexual contact with other men.

Officials say the virus has been spreading mainly through skin-on-skin contact, but they warn it might also transmit in other ways, including through touching linens used by someone with monkeypox.

People with monkeypox may experience fever, body aches, chills and fatigue. Many in the outbreak have developed extremely painful zit-like bumps. No one in the U.S. has died, but deaths have been reported in other countries.

The U.S. has a limited supply of what is considered the main weapon against the virus — a vaccine called Jynneos. The doses are currently being given to people soon after they think they were exposed. Scientists are still trying to establish how well the shots are working.

The government last week moved to stretch the supply by giving people one-fifth the usual dose, injected just under the skin, instead of a full vial injected into deeper tissue.

Many health workers may have little experience giving shots using the just-under-the-skin method, which requires different needles and syringes. Some health departments have started doing that, but some local officials have said they may need a week or more to make the change.

Officials this week announced the release of 442,000 of the smaller doses for order by state, local and territorial health departments. On Thursday, they said more is coming next week — 1.8 million doses, or 360,000 vials.

Officials also announced a new agreement with a Michigan manufacturer to help speed production of 5.5 million vaccine vials recently ordered by the U.S. government.

Under the deal, Grand River Aseptic Manufacturing will help package raw vaccine ingredients currently stored at an overseas facility owned by Bavarian Nordic, which makes the Jynneos vaccine. Officials said the extra capacity should help speed up U.S. vaccine orders, most of which weren’t expected to be delivered until next year. The Biden administration has faced weeks of criticism for not ordering more vaccine sooner.

Also on Thursday, health officials said next week they will boost the supply of TPOXX, a drug for treating monkeypox infections, by 50,000 treatment courses.
