After more than 18,000 cases of monkeypox in 78 countries, the World Health Organization (WHO) recommends targeted vaccination for people who have been exposed to an infected person and for people at high risk of exposure, including health workers, laboratory workers and people with polysexuality. the partners. “We currently do not recommend mass vaccination against monkeypox,” agency chief Tedros Adhanom Gebreyesus said on Wednesday.
He shared that a smallpox vaccine called MVA-BN has been approved for use against monkeypox in Canada, the European Union and the United States, while two other vaccines, LC16 and ACAM2000, are currently on the way. the study. “However, we still lack data on the effectiveness of monkeypox vaccines or on the number of doses that may be needed. Therefore, we urge all countries using vaccines to collect and share important data on their effectiveness,” he said. The expert added that the WHO is developing a research framework that countries could use to generate the data needed to better understand how effective these vaccines are in preventing both infection and disease, and how to use them the most. more efficiently.
Vaccination does not provide immediate protection against infection or disease and may take several weeks. “This means that those who have been vaccinated should continue to take steps to protect themselves by avoiding close contact, including sexual intercourse, with others who have or are at risk of contracting monkeypox,” the secretary stressed. general of the WHO. There are currently challenges with the availability of vaccines. Although there are approximately 16 million doses of the MVA-BN smallpox vaccine available worldwide, most are in bulk, meaning it will take several months to “fill and finish” in ready-to-use vials.
Several countries with monkeypox cases have secured vaccine supplies and WHO is in contact with other countries to assess their supply needs. “WHO urges countries that have smallpox vaccines to share them with countries that do not. We must ensure equal access to vaccines for all individuals and communities affected by monkeypox in all countries and regions,” the Ethiopian said. Although vaccines are an important tool, surveillance, diagnosis and risk reduction remain key to preventing transmission and stopping the outbreak.
