US authorizes Johnson & Johnson’s single-shot COVID-19 vaccine for emergency use

  • The J&J vaccine is the third to be greenlighted in the US after Pfizer’s and Moderna’s were provisionally approved in December
  • US President Joe Biden hails 'exciting news' but urge Americans not to let guard down

WASHINGTON: The United States on Saturday authorized Johnson & Johnson’s Covid vaccine for emergency use, giving the nation a third shot to battle the outbreak that has killed more than 500,000 Americans.
The single-shot vaccine is highly effective in preventing severe Covid-19, including against newer variants, the Food and Drug Administration (FDA) said before giving it a green light.
“This is exciting news for all Americans, and an encouraging development in our efforts to bring an end to the crisis,” US President Joe Biden said in a statement.
But he urged Americans to remain vigilant with anti-virus curbs such as social distancing, warning that new variants of the virus still posed a threat.
“But we cannot let our guard down now or assume that victory is inevitable,” he said.
A third vaccine is seen as a vital means to ramp up the immunization rate in the United States, where more than 500,000 people have lost their lives to the coronavirus.
In large clinical trials, the J&J vaccine’s efficacy against severe disease was 85.9 percent in the United States, 81.7 percent in South Africa, and 87.6 percent in Brazil.
Overall, among 39,321 participants across all regions, the efficacy against severe Covid-19 was 85.4 percent, but it fell to 66.1 percent when including moderate forms of the disease.
Crucially, analyses of various demographic groups revealed no marked differences across age, race, or people with underlying conditions.
The J&J vaccine is the third to be greenlighted in the United States after Pfizer’s and Moderna’s were provisionally approved in December.

Practical advantages
Over 65 million people in America have so far received at least one shot of either the Pfizer or Moderna vaccines — but unlike those, the J&J vaccine requires just one dose, and is stored at fridge temperatures, offering logistical and practical advantages.
The J&J shot appears less protective than Pfizer and Moderna’s two-shot regimens, which both have an efficacy of around 95 percent against all forms of Covid-19 from the classic coronavirus strain.
All three have been shown to fully protect against hospitalizations and death, however.
Nirav Shah, director of the Maine Center for Disease Control and Prevention, told The Washington Post the two earlier vaccines were tested months before the emergence of “variants of concern” that could affect the efficacy, meaning the Pfizer and Moderna results were not an “apples to apples” comparison with the J&J shot.
There was a hint, based on preliminary data, that the J&J vaccine might be effective against asymptomatic infection — though the company said it needs to do more research.
The company has announced it aims to deliver 20 million doses by the end of March, with 100 million by June — though the US is pushing to expedite that timeline.
The J&J vaccine uses a common-cold causing adenovirus, which has been genetically modified so that it can’t replicate, to carry the gene for a key protein of the coronavirus into human cells.

Australia to toughen gun laws as it mourns deadly Bondi attack

  • Footage showed one man, identified by local media as fruit seller Ahmed al Ahmed, grabbing one of the gunmen as he fired
  • Prime Minister Anthony Albanese convened a meeting of leaders of Australia’s states and territories in response on Monday, agreeing with them “to strengthen gun laws across the nation”

SYDNEY: Australia’s leaders have agreed to toughen gun laws after attackers killed 15 people at a Jewish festival on Bondi Beach, the worst mass shooting in decades decried as antisemitic “terrorism” by authorities.
Dozens fled in panic as a father and son fired into crowds packing the Sydney beach for the start of Hanukkah on Sunday evening.
A 10-year-old girl, a Holocaust survivor and a local rabbi were among those killed, while 42 others were rushed to hospital with gunshot wounds and other injuries.
Prime Minister Anthony Albanese convened a meeting of leaders of Australia’s states and territories in response on Monday, agreeing with them “to strengthen gun laws across the nation.”
Albanese’s office said they agreed to explore ways to improve background checks for firearm owners, bar non-nationals from obtaining gun licenses and limit the types of weapons that are legal.
Mass shootings have been rare in Australia since a lone gunman killed 35 people in the town of Port Arthur in 1996, which led to sweeping reforms long seen as a gold standard worldwide.
Those included a gun buyback scheme, a national firearms register and a crackdown on ownership of semi-automatic weapons.
But Sunday’s shooting has raised fresh questions about how the two suspects — who public broadcaster ABC reported had possible links to the Daesh group — obtained the guns.

- ‘An act of pure evil’ -

Police are still unraveling what drove Sunday’s attack, although authorities have said it targeted Jews.
Albanese called it “an act of pure evil, an act of antisemitism, an act of terrorism on our shores.”
A string of antisemitic attacks has spread fear among Australia’s Jewish communities after the October 7, 2023, Hamas assault on Israel and the ensuing war in Gaza.
The Australian government this year accused Iran of orchestrating a recent wave of antisemitic attacks and expelled Tehran’s ambassador nearly four months ago.
But Israeli Prime Minister Benjamin Netanyahu accused Australia’s government of “pouring oil on the fire of antisemitism” in the months before the shooting, referring to Canberra’s announcement that it would recognize Palestinian statehood in August.
Other world leaders expressed revulsion, with US President Donald Trump condemning the “antisemitic attack.”
The gunmen opened fire on an annual celebration that drew more than 1,000 people to the beach to mark Hanukkah.
They took aim from a raised boardwalk at a beach packed with swimmers cooling off on the steamy summer evening.
Witness Beatrice was celebrating her birthday and had just blown out the candles when the shooting started.
“We thought it was fireworks,” she told AFP. “We’re just feeling lucky we’re all safe.”
Carrying long-barrelled guns, they peppered the beach with bullets for 10 minutes before police shot and killed the 50-year-old father.
The 24-year-old son was arrested and remains under guard in hospital with serious injuries.
Australian media named the suspects as Sajid Akram and his son Naveed Akram.
Tony Burke, the home affairs minister, said the father arrived in Australia on a student visa in 1998 and had become a permanent resident. The son was an Australia-born citizen.
Hours after the shooting, police found a homemade bomb in a car parked close to the beach, saying the “improvised explosive device” had likely been planted by the pair.
Rabbi Mendel Kastel said his brother-in-law was among the dead.
“We need to hold strong. This is not the Australia that we know. This is not the Australia that we want.”
Wary of reprisals, police have so far avoided questions about the attackers’ religion or ideological motivations.
Misinformation spread quickly online after the attacks, some of it targeting immigrants and the Muslim community.
Police said they responded to reports on Monday of several pig heads left at a Muslim cemetery in southwestern Sydney.

- Panic and bravery -

A brave few dashed toward the beach as the shooting unfolded, wading through fleeing crowds to rescue children, treat the injured and confront the gunmen.
Footage showed one man, identified by local media as fruit seller Ahmed al Ahmed, grabbing one of the gunmen as he fired.
The 43-year-old wrestled the gun out of the attacker’s hands, before pointing the weapon at him as he backed away.
A team of off-duty lifeguards sprinted across the sand to drag children to safety.
“The team ran out under fire to try and clear children from the playground while the gunmen were firing,” said Steven Pearce from Surf Life Saving New South Wales.
Bleeding victims were carried across the beach atop surfboards turned into makeshift stretchers.
On Monday evening, a flower memorial next to Bondi Beach swelled in size as mourners gathered.
Hundreds, including members of the Jewish community, sang songs, clapped and held each other.
Leading a ceremony to light a menorah candle, a rabbi told the crowd: “The only strength we have is if we bring light into the world.”
