This is a less common technique and may require training of some healthcare workers. It also has side effects such as redness, itching, and swelling.

Shallow injections are thought to help stimulate the immune system because the skin contains numerous immune cells that target foreign invaders.

The Centers for Disease Control and Prevention said it would provide educational materials on the technology as well as conduct a broader awareness campaign for the US health sector.

Vaccine dose rationing is common in Africa and other parts of the world where medical resources are limited. In recent years, the World Health Organization has endorsed approaches to combat yellow fever, polio, and other disease outbreaks.

Both the United Kingdom and Canada have adopted single-dose vaccine strategies that prioritize those at highest risk of monkeypox. And the health departments of several large US cities, including New York, San Francisco and Washington, have adopted similar strategies amidst limited supplies.

We have shipped more than 617,000 doses of the vaccine to health authorities in the world, and we plan to distribute another 380,000 doses in the coming weeks. So far, it is recommended for people who have already had monkeypox or who may develop it from recent sexual contact in areas where the virus is endemic.

Additional human studies have shown that people given Gineos have immune responses similar to those given previous smallpox vaccines. However, Jynneos has not been tested in humans for monkeypox or its relative smallpox, which was eradicated decades ago.

This is typical of many of the national stockpile vaccines and drugs that treat rare or deadly pathogens such as anthrax and plague.

The US government has spent over $1 billion developing and stockpiling freeze-dried vaccines, replacing earlier liquid versions with shorter shelf lives. Bavarian Nordic has a 10-year contract with the US to supply the new vaccine.
