Paul Chaplin, the chief executive of Bavarian Nordic, which makes the vaccine, said on Thursday that research shows one dose provides “robust protection”. Dr Bassett, however, said full protection from the vaccine would not come until two weeks after the second dose.
What to know about the Monkeypox virus
What is monkey pox? Monkeypox is an endemic virus in parts of central and western Africa. It is similar to smallpox, but less serious. It was discovered in 1958, after outbreaks occurred in monkeys kept for research, according to the Centers for Disease Control and Prevention.
New York health officials have said people in any of the following categories are eligible for the vaccine:
People with recent exposure to monkeypox within the past 14 days.
People at high risk of recent exposure to monkeypox, including members of the gay, bisexual, transgender and other men who have sex with men communities who have had intimate or skin-to-skin contact with others during past 14 days in areas where monkeypox is spreading.
Individuals who have had skin-to-skin contact with someone on a social network with monkeypox, including men who have sex with men who meet partners through an online website, app digital or a social event, such as a bar or party.
Partly because the categories are broad, demand for the vaccine is extremely high. The roughly 2,500 appointments were completed within minutes on Wednesday, health officials said.
Huge frustration over access to the vaccine spread on Wednesday as people spent hours not knowing if they had missed the rollout or if more doses were coming.
Eugene Resnick, who works as a spokesman for the Metropolitan Transportation Authority, said he spent nine hours refreshing the city’s web page before he could finally make an appointment when a second set was released just before 19 hours.
“I am frustrated, angry, disappointed with the Department of Health,” he said. “I am an insider who works in the government. I can’t imagine this being at all accessible to the average person who isn’t on Twitter.
Joseph Osmundson, a microbiologist and queer activist helping to increase access to the vaccine, said the city had done the right thing by opening a clinic in Harlem, in addition to the one in Chelsea, to distribute the vaccine, but that there had to be a more urgent effort to get more vaccines to the city soon.
“At all levels, there is such frustration in the community,” Mr. Osmundson said. He said people he knows are trying to be careful but are increasingly angry at what they feel is a lack of urgency to protect the gay community in particular: “We feel like ‘be left behind and then blamed for the spread.”
