COVID-19 vaccines this fall are likely to be based on the Omicron variant of the coronavirus rather than the original strain, although some experts suggest they may only offer significant benefits for older and immunocompromised people.

On Friday, the World Trade Organization approved vaccine patent waivers to increase the availability of COVID-19 vaccines to lower-income countries.

The World Health Organization is giving the monkeypox virus a new name in an attempt to quell the stigma and discrimination that might go with it.

The World Health Organization is looking into reports that the monkeypox virus is present in the semen of patients, exploring the possibility that the disease could be sexually transmitted, a WHO official said on Wednesday.

The BA.4 and BA.5 sub-variants of Omicron are estimated to make up about 8.3 percent and 13.3 percent of the coronavirus variants in the United States as of June 11, the U.S. Centers for Disease Control and Prevention (CDC) said on Tuesday.

The World Health Organization will convene an emergency committee on Thursday next week to assess whether the monkeypox outbreak represents a public health emergency of international concern.

The World Health Organization said on Thursday its latest investigation into the origins of COVID-19 was inconclusive, largely because data from China is missing, another blow to the WHO’s years-long effort to determine how the pandemic began.

There have been more than 1,000 monkeypox cases reported to the World Health Organization in the current outbreak outside the countries in Africa where it more commonly spreads.

The BA.4 and BA.5 sub-variants of Omicron are estimated to make up nearly 5% and 8% of the coronavirus variants in the United States as of June 4, the U.S. Centers for Disease Control and Prevention (CDC) said on Tuesday.

Diagnostic companies are racing to develop tests for monkeypox, hoping to tap into a new market as governments ramp up efforts to trace the world’s first major outbreak of the viral infection outside of Africa.
