Monkeypox vaccine appears to be working, but CDC still recommends precautions


Federal health authorities are urging at-risk Americans to continue taking precautions against monkey poxweather first data suggests that the Jynneos vaccine for the virus may be helping to delay cases.

The figures, released Wednesday in the CDC’s website, counted reported monkeypox infections in people eligible for the vaccine in 32 states. Through the end of August, infection rates were 14 times higher in people who had not received at least one vaccine.

The new findings come as the Biden administration is touting new moves to expand eligibility for vaccines and other initiatives aimed at reducing serious infections and deaths.

“These new data give us a level of cautious optimism that the vaccine is working as intended. These early findings, and similar results from studies in other countries, suggest that even one dose of the monkeypox vaccine offers at least some initial protection against infection., “CDC Director Dr. Rochelle Walensky told a briefing.

However, the CDC says its new “crude case rate” data has several important limitations that make it difficult to determine the precise impact the vaccine is having on reducing the bud.

For example, people who are vaccinated are less likely to engage in activities that increase their risk of contracting the virus, which is spread largely through intimate contact between men who have sex with men.

Not all states report enough data to feed into the estimate. New York, which represents more than 15% of the 25,509 inhabitants of the country. confirmed casesnot yet included in rates.

The agency is still waiting for more data after people receive the second dose of the injection. Laboratory data suggests that the follow-up injection will provide “longer-lasting protection” against monkeypox, Walensky said.

The National Institutes of Health also continues to collect data from your clinical trial examining the “intradermal” approach to administering injections, which is being used in the US to stretch the vaccine supply. That study isn’t expected to return its first results until early 2023.

For now, Walensky urged vaccinated people to continue taking steps to “further protect themselves from infection.”

“Consider reducing behaviors that could increase the risk of exposure. These prevention measures are key to continuing to reduce monkeypox infections,” Walensky said.

Vaccine expansion

The promising data on the shots comes as the Biden administration is now moving to ease barriers it says may have deterred some from receiving the monkeypox vaccine.

Last week, the CDC said so now I had recorded more than half a million first doses of vaccine administered nationwide. that works for about a third of the number of people the White House estimates to be at “increased risk of contracting the virus.”

citing a increased shots offerFederal health officials said they are now moving to a “pre-exposure prophylaxis” or PrEP approach to vaccine eligibility, which means offering it to people as a preventative measure before they have a known exposure.

Previously, the CDC only recommended the shots for “post-exposure prophylaxis” in people who were likely already exposed to the virus.

Federal guidelines now they say health departments should offer it to broader groups of Americans before they are exposed to the virus, including all gay men who have been diagnosed with a sexually transmitted disease in the last six months.

“That increases who is eligible for vaccination and encourages vaccine providers to downplay risk assessments of people seeking the vaccine. Fear of revealing sexuality and gender identity should not be a barrier,” said Dr. Demetre Daskalakis, White House deputy response coordinator for monkeypox. .

The CDC also updated your guide to allow injections to be given in other parts of the body, such as the upper back or shoulder.

“Many jurisdictions and advocates have told us that some people are refusing the monkeypox vaccine because of the stigma associated with the visible, but temporary, mark that is often left on the forearm,” Daskalakis said.

serious infections

While most monkeypox infections resolve after weeks of often very painful rashes and lesions, a handful of patients have ended up in the hospital and at least an american death has been officially attributed to the virus.

Health officials have raised concerns about rising reports of serious infections, even as cases have slowed down overall. Walensky said Wednesday that he was not aware of any of these types of serious infections in people who had been vaccinated with Jynneos.

an updated “technical report” The agency’s release is also expected early next month, outlining trends in where and how the virus continues to spread.

“We want to draw attention to the fact that we’ve been hearing about some serious infections in recent weeks,” the CDC’s Dr. Agam Rao said in a webinar hosted by the Infectious Diseases Society of America. weekend.

The agency has been working on updated recommendations for doctors treating these serious cases, whose federal data suggests they are now occurring primarily in immunocompromised Hispanic or black men with advanced HIV.

“While we’re finding it, I guess, comforting or reassuring that the number of cases is going down, we just want to highlight that some serious infections are happening,” Rao said.
