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.

Austrian man arrested in Croatia with deceased woman as passenger in his car

A 65-year-old Austrian citizen was arrested at a border checkpoint in Croatia after attempting to enter the country in his car with a deceased woman sitting as a passenger, police announced on Tuesday.

The man was detained in a routine check in late November in Gunja, a border area separating Bosnia from Croatia, the police told AFP. Suspicious because they saw “no consciousness or movement” from the passenger, Croatian officers called a doctor, who confirmed the death of the 83-year-old woman, also Austrian, according to her identification.

The woman’s relationship to the suspect is unknown. She had died in Bosnia, and the man intended to repatriate her body to Austria to “avoid the formalities related to transporting a corpse,” according to the police. Croatian media reported that the man was her legal guardian.

Once her death was confirmed, a funeral service took charge of the body.

Colombian nationals arrested for human trafficking and disappearance of migrant boat

 

Colombian authorities arrested two nationals accused of the illegal trafficking of migrants to the United States and of endangering lives due to the disappearance of a boat with 40 people aboard, U.S. Department of Justice officials reported on Tuesday.

Hernando Manuel de la Cruz Rivera Orjuela, 52, and Luis Enrique Linero Pinto, 40, both Colombian citizens, were arrested on December 13 in Colombia at the request of the United States for their alleged involvement in a “transnational human trafficking operation,” the department said in a statement.

According to the charges, the detainees were transporting migrants to San Andrés Island in the Caribbean, where they would then be taken by boat to Nicaragua. The goal was to reach the United States through Central America and Mexico.

The accused are said to have advised the migrants on how to reach San Andrés Island, where they personally received them, arranged accommodations, and “took them to the boats that transported them to Nicaragua so they could enter the United States illegally,” the statement reads.

“These defendants put several migrants on the boat that disappeared off the coast of Nicaragua in 2023,” said Deputy Attorney General Nicole M. Argentieri, head of the U.S. Department of Justice’s Criminal Division, as cited in the statement.

Both men are “directly and personally responsible for the illicit trafficking of migrants on that vessel,” according to the indictment dated October 23.

Homemade landmine explosion in Michoacán kills two soldiers, injures five

Two soldiers were killed and five others were injured by the explosion of homemade landmines planted by a criminal group in a mountainous area of the Mexican state of Michoacán (west), the Secretary of Defense reported on Tuesday.

The attack occurred on Monday morning in the municipality of Cotija, a border area between Michoacán and the state of Jalisco, when the military was conducting a reconnaissance mission after receiving information about an armed camp in the area, explained Secretary General Ricardo Trevilla.

“At that moment, an improvised explosive device detonated. Unfortunately, two soldiers lost their lives, and five others were injured,” the military leader detailed. The affected soldiers were airlifted to hospitals in the region by a military helicopter, while the rest of the team continued with the reconnaissance of the area.

Trevilla stated that before the explosion, the military unit had located the dismembered bodies of three people, and upon continuing the mission, they confirmed the camp was abandoned.

Asked about the individuals responsible for placing the explosives, the general suggested they could be criminals linked to the local group Cárteles Unidos, which operates in Michoacán and uses these tactics in their territorial dispute with the Jalisco New Generation Cartel, one of the most powerful criminal organizations in the country.
