WHO fears Omicron could spur fresh vaccine hoarding

The World Health Organization said Thursday it remained unclear whether additional Covid-19 vaccine doses are needed to protect against the new Omicron variant, and urged wealthy countries to avoid hoarding the jabs.

The UN health agency’s vaccine advisors warned that a rush to stockpile more jabs, especially without clear evidence they are needed, would only exacerbate the already glaringly inequal vaccine access around the globe.

“As we head into whatever the Omicron situation is going to be, there is a risk that the global supply is again going to revert to high-income countries hoarding vaccine to protect (their populations) … in a sense in excess,” WHO vaccines chief Kate O’Brien told reporters.

Her comment came after preliminary results published Wednesday indicated that three doses of the Pfizer-BioNTech Covid vaccine were needed to obtain the same level of protection against Omicron as two doses provided against the initial strain.

O’Brien said the WHO was examining the data, and that it may turn out that “additional doses have benefit to provide added protection against Omicron”, but stressed it was still “very early days”.

While there was still little evidence that additional doses were needed to protect against developing severe Covid disease, many vulnerable people and health workers in poorer nations have yet to receive a single dose and remain at great risk.

O’Brien pointed out that the world had only just begun addressing the dangerous inequity in vaccine access in the past two months, with more donated doses and large shipments going to underserved countries.

“We have to make sure that it continues,” she said, warning that efforts by wealthy countries to stockpile more jabs for their people would only prolong the pandemic.

“It’s not going to work from an epidemiologic perspective, and it’s not going to work from a transmission perspective, unless we actually have vaccine going to all countries,” she said.

“Where transmission continues … is where the variants are going to come from,” she warned, urging “a much more rational global perspective from countries about what’s actually going to shut down this pandemic.”

U.S. lowers travel advisory for much of Venezuela but keeps high-risk zones under warning

The U.S. Department of State announced on Thursday that it has lowered its travel advisory for much of Venezuela to Level 3 (“Reconsider Travel”), reflecting what it described as improved security conditions in parts of the country.

However, the agency will maintain the highest Level 4 warning (“Do Not Travel”) for several regions, including the states of Táchira, Amazonas, Apure, Aragua and Guárico, as well as rural areas of Bolívar, citing ongoing risks such as crime, kidnapping and terrorism.

The updated advisory marks a shift from December, when the United States raised the alert for Venezuela to Level 4 nationwide, warning of severe security threats.

Despite the partial downgrade, U.S. authorities continue to urge caution, emphasizing that conditions remain volatile in certain areas and that travelers should carefully assess risks before planning any trips to the country.

EU lawmakers move to ban AI tools that generate non-consensual nude images

Members of the European Parliament are pushing to ban across the bloc artificial intelligence services that allow users to digitally “undress” people without their consent.

The proposal, adopted on Wednesday at committee level, aims to prohibit applications that generate non-consensual explicit images. Irish lawmaker Michael McNamara, one of the sponsors, said the measure seeks to stop tools that “have caused significant harm for the benefit of a few.”

Dutch MEP Kim van Sparrentak welcomed the move, calling it “a major victory, especially for women and children in Europe.”

The amendment, part of broader EU legislation on artificial intelligence, was approved by the Parliament’s civil liberties and internal market committees. It specifically targets systems that use AI to create or manipulate sexually explicit or intimate images resembling identifiable individuals without their consent.

The proposal will be put to a full vote in the European Parliament on March 26. If adopted, lawmakers and European Union member states will need to agree on a final version before it can take effect.

Separately, representatives of the 27 EU countries recently backed a Franco-Spanish amendment seeking to ban AI services used to generate non-consensual sexual images or child sexual abuse material.

The initiative follows controversy surrounding a feature introduced in Grok, developed by xAI, which allowed users to create simulated nude images from real photos. The tool sparked widespread criticism and prompted an EU investigation.

In response, xAI restricted image generation features in mid-January to paying subscribers and stated it blocks the creation of sexualized images in jurisdictions where such content is illegal.
