No preferential nod for Omicron Covid jabs: WHO experts

AFP

There is not yet enough evidence to recommend Omicron-specific Covid-19 jabs over the original versions, the World Health Organization’s vaccine experts said Tuesday.

Four variant-containing mRNA vaccines which include Omicron subvariants BA.1 or BA.4/5 in combination with the ancestral virus have been authorised for use as booster doses.

The vaccines adapted to the globally-dominant variant may offer only a “minute incremental benefit”, the WHO’s Strategic Advisory Group of Experts on Immunisation (SAGE) said.

The WHO has given its Emergency Use Listing green light to nine Covid-19 vaccines and variations — Pfizer/BioNTech, AstraZeneca, Janssen, Moderna, Sinovac, Sinopharm, Bharat Biotech, Novavax and CanSinoBIO.

“Currently available data are not sufficient to support the issuance of any preferential recommendation for bivalent variant-containing vaccine boosters over ancestral-virus-only boosters”, SAGE said in a statement.

SAGE executive secretary Joachim Hombach said the experts had found that the variant-containing vaccines neutralise to the same extent as the ancestral ones, with a “slightly superior neutralisation of the Omicron variant”.

“It’s a relatively modest effect which we can see in the laboratory,” he said.

“What we cannot do is to relate these laboratory measures with an increase in clinical protection,” because such effectiveness data is not yet available.

“Since our recommendations should be really grounded in evidence, we cannot issue a preferential statement for these vaccines,” Hombach said.

“These vaccines are absolutely fine, but what is much more important” for protection “is that you actually take the vaccine” — whether tweaked for Omicron or not.

“This is what is making the difference,” whether for the first or second booster, Hombach said.

The Omicron variant accounted for 99.9 percent of virus samples collected in the last 30 days that have been sequenced and uploaded to the GISAID global science initiative.

Of these, the BA.5 group of Omicron sub-variants remain globally dominant at 81 percent, followed by BA.4 at eight percent and BA.2 at three percent.

As of October 2, more than 615 million confirmed Covid-19 cases and over 6.5 million deaths have been reported globally to the WHO.

Trump to build $200M ballroom at the White House by 2028

The U.S. government under President Donald Trump announced on Thursday that it will begin construction in September on a new 8,000-square-meter ballroom at the White House.

The announcement was made by Karoline Leavitt, the administration’s press secretary, during a briefing in which she explained that the expansion responds to the need for a larger venue to host “major events.”

“Other presidents have long wished for a space capable of accommodating large gatherings within the White House complex… President Trump has committed to solving this issue,” Leavitt told reporters.

The project is estimated to cost $200 million, fully funded through donations from Trump himself and other “patriots,” according to a government statement. Construction is scheduled to begin in September and is expected to be completed before Trump’s term ends in 2028.

The Clark Construction Group, a Virginia-based company known for projects such as the Capital One Arena and L’Enfant Plaza in Washington, D.C., has been selected to lead the project.

The sentence was handed down by federal judge Timothy J. Corrigan on Tuesday, July 29.

Eduardo Aníbal Escobar (45) was sentenced to 4 years and 9 months in prison, Carlos Alberto Rodríguez (36) to 3 years and 4 months, and Adelmy Tejada (57) to 18 months in prison, followed by 6 months of house arrest. All three pled guilty on April 3, 2025.

In addition to the prison terms, the court ordered restitution payments totaling $36,957,616 to the IRS for unpaid payroll taxes, and $397,895 to two insurers for workers’ compensation claims related to the scheme.

Kremlin hails preparedness after Kamchatka quakes leave no casualties

The Kremlin expressed relief that the earthquakes that struck Russia’s Kamchatka Peninsula today —the first being the strongest since 1952— resulted in no casualties, and emphasized that the region is well prepared to face such natural disasters.

“Thank God, there were no victims,” said Kremlin spokesman Dmitry Peskov during his daily press briefing.

The presidential representative stated that “all alert systems were activated in time, and evacuations were organized for residents in areas requiring it in response to tsunami threats.”

“Overall, the seismic resilience of the buildings proved effective (…) Therefore, we can say that the technological preparedness demonstrated a high level,” Peskov added.
