BioNTech Produces 10 Times More Antibodies than China's Sinovac: Study

People who received BioNTech's coronavirus vaccine had ten times the amount of antibodies than those given China's Sinovac, a Hong Kong study has shown, adding to growing data on different jabs' effectiveness.

The University of Hong Kong (HKU) research, based on a study of 1,442 healthcare workers, was published in Lancet Microbe on Thursday.

Researchers said antibodies are not the only measure of a vaccine's success at fighting a particular disease.

But they warned that "the difference in concentrations of neutralizing antibodies identified in our study could translate into substantial differences in vaccine effectiveness".

Those who received Sinovac had "similar or lower" levels of antibodies to those seen in patients who caught and successfully fought off the disease.

The study adds to the growing body of evidence that vaccines using pioneering mRNA technology -- such as BioNTech and Moderna -- offer better protection against the coronavirus and its variants that those developed by more traditional methods such as using inactivated virus parts.

Traditional vaccines are cheaper to produce and less complicated to transport and store, making them a vital tool for fighting the pandemic in less wealthy countries.

- 'Many lives still saved' -
Epidemiologist Ben Cowling, one of the report's authors, said people should still get vaccinated with Sinovac if there was no other option because some protection was always better than none.

"Don't let the perfect be the enemy of the good," he told AFP.

"It is clearly better to go and get vaccinated with an inactivated vaccine than to wait and not get vaccinated," he added.

"Many, many lives have been saved by the inactivated vaccine."

The researchers said their data suggested "alternative strategies" such as earlier booster shots might be needed to increase protection for those who have received Sinovac.

Cowling said when to give booster shots would be the next phase of their ongoing studies.

"The priority would be boosters for people who received Sinovac while boosters for people who initially received BioNTech might not be so urgent," he said.

- Politics -
Hong Kong has been a world leader in studying coronaviruses ever since a SARS outbreak which began in southern China swept through the city in 2003.

The city currently offers both German-made BioNTech shots and Sinovac.

Despite ample supplies, take-up has been slow, with only 28 percent of the city's 7.5 million residents fully vaccinated with two shots.

So far some 2.6 million BioNTech doses have been administered compared to 1.8 million Sinovac shots.

The rollout has been caught up in Hong Kong's febrile politics, as China cracks down on dissent in the city in response to huge and often violent democracy protests two years ago.

At the start of the vaccination campaign Hong Kong's pro-Beijing leaders very visibly and near unanimously opted for Sinovac.

One doctor's clinic that recommended BioNTech over Sinovac was kicked out of the city's vaccination program.

Many of the city's leading epidemiologists have gone with BioNTech, and said publicly that it is their preferred shot.

US: Shark Attack on Alabama Teen Inspires Start of National Alert System

Lulu Gribbin was 15 when she survived a shark attack off the coast of Florida. She lost her left hand, part of her right leg and almost her life.

What she didn’t know when she entered the water on that day in 2024 was that another woman had been bitten by a shark 90 minutes earlier and just 3 miles (4.8 kilometers) down the beach. Had she known about the earlier attack, there is no way she would have been swimming, she said.

Gribbin’s story has inspired new federal legislation to authorize emergency alerts to mobile phones to warn beachgoers when a shark has bitten someone in the area.

President Donald Trump last week signed “Lulu’s Law,” which requires the Federal Communications Commission to allow the emergency messages. The legislation, which Gribbin advocated for, authorizes the warnings by classifying a shark attack as an event for which an emergency alert can be issued. It is up to states to implement the warnings.

Gribbin’s home state of Alabama approved such a warning system last year.

“It’s really just common-sense legislation. It says that whenever there has been a shark attack in a certain area where you are near, it will send an alert to your phone, exactly like how an Amber Alert system works when a child is abducted,” The Associated Press quoted her as saying.

Gribbin said she hopes the alert system will help prevent attacks like hers. “I definitely see this law working in the future and I'm really excited to hopefully save lives,” she said.

A fight to survive Gribbin was one of three people bitten by a shark on June 7, 2024, off the Florida Panhandle.

She was on a mother-daughter trip to the Florida Panhandle. Gribbin said she and her friend had been diving for sand dollars.

“All of the sudden my best friend yelled, ‘Shark!’ and so we all started swimming for our lives,” Gribbin recalled. She said she remembered that sharks are attracted to frantic splashing and yelled for everyone to be calm. Gribbin, who was closest to the shark, was bitten.

“The shark bit off my hand first, and I raised my arm out of the water, and there was just flesh and bone there,” Gribbin said. The shark then latched onto her leg. A man punched the shark off her and strangers on the beach rushed to help. She was flown by helicopter to a nearby hospital.

Doctors were able to save the teen's life but had to amputate part of her right leg.
Choosing positivity throughout her recovery In the hospital, Gribbin made a deliberate decision to choose joy and to never give up.

Gribbin was fitted with prosthetic limbs, quickly regained her ability to walk, returned to sports and got her driver’s license. She has gone back in the water and learned to surf, meeting Bethany Hamilton, a professional surfer who lost her arm in a shark attack.

US Sen. Katie Britt, the Alabama Republican who sponsored the legislation, said the legislation happened because of the teen's “courage, perseverance, and advocacy to protect future beachgoers.”

“Because of her strength, lives will be changed. We should all be inspired by her,” Britt said.

Three traumatized wallabies living far from their usual Australian habitat were recovering in a Spanish zoo on Thursday after being rescued from a rural cannabis plantation full of rotting animals, AFP reported.

Police said the marsupials, similar to but smaller than kangaroos, were saved alongside 14 dogs, three calves and two deer from their ordeal in the central municipality of Malagon on Tuesday.

During their raid, "the officers came across an unusual scene when they found dozens of animals in woeful hygiene and sanitary conditions", police said in a statement.

The trapped animals lived alongside the corpses of other creatures, "some of them in an advanced state of decomposition", including "hundreds of chickens" who were tossed in bags to the dogs as food.

The wallabies and the deer shared a garden used by the suspects and their young children, the police added.

The wallabies were later taken to a zoo in the central province of Toledo.

Officers seized almost 1,000 cannabis plants from the site, which included an underground production area and was illegally connected to the power grid.

Two suspects were arrested on charges including animal abuse and offences against flora, fauna and public health.

Hundreds of people were besieging Lidl supermarkets in and around Paris Thursday, with scuffles and shouting matches breaking out as residents scrambled to get their hands on bargain air-cooling units before the next heatwave hits the French capital.

With few air conditioners on sale elsewhere for less than 1,200 euros ($1,400), police were called to at least two stores as huge crowds descended on Lidl supermarkets trying to get their hands on basic models on sale for as low as 179 euros, AFP said.

Mousa Traore, who had been waiting for more than an hour along with some 200 other customers at a small Lidl store in a northern Paris neighborhood, said he had been told there were only two units on sale, AFP .

"But then the police came and we were told there were none. The police officers took them I think," he said laughing.

France has just been through a record heatwave that led to excess deaths, overwhelmed hospitals, closed schools and cancelled music festivals, and weather services are forecasting another round of hot weather this coming weekend.

Due to historically mild summers, few homes and schools in France are equipped with air conditioning, making them ill-equipped to face increasingly frequent heatwaves that scientists say are linked to human-induced climate change.

- 'It's madness' -

Even so, the crowd at the Lidl store was mostly good-humored, but some disputes broke out as people tried to jump the queue.

"I am not opening the store unless you leave," a manager shouted, as customers harangued her, with another member of staff telling AFP only two air conditioners had been delivered.

He refused to say if they had already been sold.

Hundreds more descended on a supermarket in Sevran, with cars queuing for the store blocking the center of the poor northern suburb. It was much the same story in nearby suburb of Livry-Gargan.

"I give up, it's madness. I abandoned my car several streets away to get there on foot but there is already a huge queue of people in the car park. It's impossible," one local called Lolo told AFP.

The rush for cooling units comes despite longstanding skepticism towards air conditioning in France.

Eight in 10 people view it as environmentally unfriendly, according to a survey of more than 1,000 people published last month.

But attitudes appear to be shifting as temperatures climb, with cooling units flying off shelves.

In the midst of the heatwave on June 22, hypermarket operator Carrefour had sold 30,000 units by 6:30 pm - "a thousand times more than on a normal day", CEO Alexandre Bompard said.

The share of French households equipped with air conditioning rose from 18 percent in 2023 to 24 percent in 2025, according to the state environment agency Ademe.

Air conditioning has emerged as a political weather vane in France, with the main far-right opposition party criticizing the government for not having prepared for hotter weather, and ecologists warning of the heavy energy demands of running air conditioners.
