The United States will soon expand its monkey vaccination program. On Tuesday night, the Biden administration announced plans to release stockpiles of more than a million vaccines to the public by the end of the fall. Vaccines are given primarily to close contacts of confirmed cases and to other people at high risk, such as gay and bisexual men who have multiple sexual partners in areas where new outbreaks have been reported.
Updated strategy announced The U.S. Department of Health and Human Services on Tuesday called for the gradual delivery of the JYNNEOS vaccine to the country. In the coming weeks, about 300,000 doses will be distributed nationwide, including 56,000 doses immediately. Another 750,000 doses will be available during the summer. Up to 500,000 doses must be tested and released by the end of the year. Overall, 1.6 million doses of the two-dose vaccine are expected to be in stock this year.
Vaccines have become available so quickly because monkeypox virus is closely related to The smallpox virus, which is now extinct it was wiped out in the 1980s through a massive global vaccination campaign. Countries still have stockpiles of smallpox vaccines, but in part because the chances of the virus being resurrected as a biowealth agent are always low. And these vaccines are thought to be effective against nearby viruses, such as monkeys. In fact, smallpox vaccines do not contain the virus itself, but another virus called a vaccine.
The United States also has large stocks of ACAM2000 smallpox vaccine, and HHS has said it will sue.wasdiactions that require it. However, the ACAM2000 vaccine has more serious side effects than JYNNEOS, making it less suitable for mass distribution, the agency said. In 2019, JYNNEOS has become The first smallpox and smallpox vaccine in the United States. This monkey is estimated to be 85% effective against smallpox, but this estimate is based on limited real-world data. The vaccine can also be given to people immediately after a suspected exposure, which should reduce the risk of contracting the disease.
By announcing the expansion of its reserves, the United States is following in its footsteps Other countries like the UK. Like these countries, the United States prioritizes doses based on the risk of human exposure. People who have had close, long-term contact with confirmed or suspicious individuals at the top, then people who have been diagnosed with smallpox in their sexual partners, and finally “men who have had sex with men who have had more than one sexual partner recently. in an area where monkeys have smallpox or monkey disease is spreading. ” At this stage, factors such as human health are also taken into account.
“Currently, our goal is to ensure that the limited supply of the JYNNEOS vaccine is extended to those who will benefit from it immediately, as we continue to provide additional doses of the vaccine,” said Down O’Connell, HHS Assistant Secretary for Preparation and Response. in it message.
Smallpox is thought to infect rodents in the first place. Until recently, it was only occasionally transmitted from animals to humans after it was discovered in the 1950s. However, their number exceeded 4,000 confirmed or suspected This year, more than 300 cases have been reported in people around the world, including in the United States, far more than any previous epidemic in parts of Africa. Although it has been circulating in humans at low levels for several years, its current prevalence is closely linked to sexual intercourse. There are still epidemics involved in the first place Men who sleep with men, but the virus can be transmitted to anyone in close contact with someone’s infected rashes and respiratory particles.
Last weekend, the World Health Organization backed out Declaring a public health emergency related to monkey smallpox is yet to be announced, but they stressed that more international cooperation and action is needed to contain the virus until it becomes permanently endemic in many parts of the world.
