CDC: 2 doses of smallpox vaccine 86% effective against infection

A vaccination campaign against monkeypox (formerly known as monkeypox) after an outbreak that swept the United States last year has been very effective in preventing infection, according to new federal data.

A new study released Thursday by the Centers for Disease Control and Prevention (CDC) found that one dose of the JYNNEOS vaccine was 75% effective, while two doses of the vaccine was 86% effective.

The study comes after the CDC and the Chicago Department of Public Health reported on a recent smallpox outbreak.

Among immunocompromised patients, one dose of the vaccine was 51% effective and two doses was 70.2% effective.

CDC officials said the results showed the importance of risk groups being vaccinated or receiving a second dose among those who were only partially vaccinated before the summer.

As of the end of March, about 31,000 cases of smallpox and 42 deaths have been reported since the outbreak last year, according to the report.

The outbreak has focused primarily on men who have sex with men, a group that includes people who self-identify as gay, bisexual, transgender and non-binary.

Anyone can be in danger

Health officials have begun advising anyone who has been exposed to or at risk of Mpoxa to get vaccinated with the JYNNEOS vaccine, which was approved by the Food and Drug Administration (FDA) in 2019.

To increase the number of available doses of JYNNEOS, In August, the FDA approved a proven intradermal vaccine strategy. only under the first layer of skin, not subcutaneously or under all layers of skin.

This allows one vial of vaccine to be administered in five separate doses instead of one dose. Between August 2022 and March 2023, a total of 309 patients who were vaccinated were compared with 608 patients who were not vaccinated.

Not only was the effectiveness of the vaccine shown, there was also little difference in the effectiveness of the vaccine when it came to the method of injection, whether subcutaneous or intradermal.

They insist that vaccination is an important tool to prevent smallpox, and to consider additional precautions to reduce exposure, especially among immunocompromised people.
