Ring vaccination works for smallpox because the pattern of human-to-human transmission is predictable and disrupts the chains of transmission. The process is simple: Find the people most at risk of infection, get them vaccinated. But to take those actions today to prevent smallpox in monkeys, you have to find the cases, you have to identify the people who are likely to be exposed to them — and importantly, you have to get the vaccine. -Please for distribution. So far, in the US, none of those efforts have gone well, and epidemiologists, scientists, and LGBTQ sexual health experts are doubting that ring vaccination is successful.
However, the numbers are growing too fast. “If there were five people, we might do our best to try to inject it,” said Gregg Gonsalves, an associate professor of epidemiology at the Yale School of Public Health and a longtime HIV/AIDS activist. ring vaccine. “But now, when you’re dealing with thousands of likely cases in the US, trying to track them all down and vaccinate everyone who comes into contact with them doesn’t seem to work. out.”
So any attempt to identify those most at risk, to warn them and protect them, will have to rely on incomplete information. According to Steven Thrasher, assistant professor of journalism at Northwestern University and author of a new book on the interplay of viral infections and inequality, if ring vaccination is a barrier around risk infection.
Angela Rasmussen, a virologist and associate professor at the International Foundation for Research in Infectious Diseases and Vaccines-The International Vaccine Center agrees: “As far as I can tell, contact tracing is complex, and Tests were essentially unavailable until last week. at the University of Saskatchewan. “The vaccine is being released on a drip, and it looks like anyone who signs up fast enough can get it. But that’s not ring vaccination. It’s just about providing a dose for people who might be at risk.”
There’s a lot to unpack here and a lot to blame. Start with vaccines. Smallpox in monkeys, a disease that spreads to humans from wild animals as well as from person to person, has been reported frequently in Africa. for decades. (Whether the international community should start taking an interest in it, rather than just adjusting it now, is a worthy discussion.) and a newer vaccine with fewer side effects. When the US government first noticed the outbreak in late May, it only 32,000 won Two doses of the safer vaccine are available in the Strategic National Stockpile. Another million doses were hung – in bottles and ready to ship – at a factory in Denmark, but the Food and Drug Administration did not approve their distribution. Earlier this month, the Department of Health and Human Services placed an order for 5 million doses newer vaccines, but most won’t be available until next year.
The limited doses available were sent to state health departments according to an HHS algorithm that calculates the ratio of detected cases to the number of people thought to be most at risk. That sent most of them to major cities: New York, Los Angeles, San Francisco, Chicago, among others. In New York City, register online for 9,200 vaccination appointments fill in 7 minutes.
