United States health advisers endorsed a one-dose COVID-19 vaccine from Johnson & Johnson on Friday, putting the nation on the cusp of adding an easier-to-use option to fight the pandemic.

The acting head of the Food and Drug Administration (FDA) said in a statement that the agency will move quickly to follow the recommendation, which would make J&J’s shot the third vaccine authorised for emergency use in the US Vaccinations are picking up speed, but new supplies are urgently needed to stay ahead of a mutating virus that has killed more than 500,000 Americans.

After daylong discussions, the FDA panellists voted unanimously that the benefits of the vaccine outweighed the risks for adults. Once FDA issues a final decision, shipments of a few million doses could begin as early as Monday.

“There’s an urgency to get this done,” said Dr Jay Portnoy of Children’s Mercy Hospital in Kansas City, Missouri. “We’re in a race between the virus mutating — and new variants coming out that can cause further disease — and stopping it.”

More than 47 million people in the US, or 14 per cent of the population, have received at least one shot of the two-dose vaccines from Pfizer and Moderna, which FDA authorized in December. But the pace of vaccinations has been strained by limited supplies and delays due to winter storms.

While early J&J supplies will be small, the company has said it can deliver 20 million doses by the end of March and a total of 100 million by the end of June.

J&J’s vaccine protects against the worst effects of COVID-19 after one shot, and it can be stored up to three months at refrigerator temperatures, making it easier to handle than the previous vaccines, which must be frozen.

One challenge in rolling out the new vaccine will be explaining how protective the J&J shot is after the astounding success of the first US vaccines.

“It’s important that people do not think that one vaccine is better than another,” said panellist Dr. Cody Meissner of Tufts University.

The two-dose Pfizer and Moderna shots were found to be about 95 per cent effective against symptomatic COVID-19. The numbers from J&J’s study are not that high, but it's not an apples-to-apples comparison.

One dose of the J&J vaccine was 85 per cent protective against the most severe COVID-19. After adding in moderate cases, the total effectiveness dropped to about 66 per cent.

Some experts fear that lower number could feed public perceptions that J&J’s shot is a “second-tier vaccine.” But the difference in protection reflects when and where J&J conducted its studies.

J&J’s vaccine was tested in the US, Latin America and South Africa at a time when more contagious mutated versions of the virus were spreading. That wasn’t the case last fall, when Pfizer and Moderna were wrapping up testing, and it’s not clear if their numbers would hold against the most worrisome of those variants.

Importantly, the FDA reported this week that, just like its predecessors, the J&J shot offers strong protection against the worst outcomes, hospitalisation and death.

While J&J is seeking FDA authorisation for its single-dose version, the company is also studying whether a second dose boosts protection.

Panel member Dr Paul Offit warned that launching a two-dose version of the vaccine down the road might cause problems.

“You can see where that would be confusing to people thinking, ’Maybe I didn’t get what I needed,’” said Dr Offit, a vaccine expert at Children’s Hospital of Philadelphia. “It’s a messaging challenge.”

J&J representatives said they chose to begin with the single shot because the World Health Organisation and other experts agreed it would be a faster, more effective tool in an emergency.

Cases and hospitalisations have fallen dramatically since their January peak that followed the winter holidays. But public health officials warned that those gains may be stalling as more variants take root in the US.

“We may be done with the virus, but clearly the virus is not done with us,” Centre for Disease Control and Prevention director Dr Rochelle Walensky, said during a White House briefing Friday. She noted that new COVID-19 cases have increased over the past few days.

While it’s too early to tell if the trend will last, Dr Walensky said adding a third vaccine “will help protect more people faster.” More vaccines are in the pipeline.

On Sunday, a CDC panel is expected to meet to recommend how to best prioritise use of the J&J vaccine.

Other parts of the world already are facing which-is-best challenges. Italy’s main teachers’ union recently protested when the government decided to reserve Pfizer and Moderna shots for the elderly and designate AstraZeneca’s vaccine for younger, at-risk workers.

AstraZeneca’s vaccine was deemed to be about 70 per cent effective in testing. Canada became the latest country Friday to allow use of AstraZeneca’s vaccine.

Finance Minister Simon Birmingham has called for a safer and more respectful political debate after South Australian Liberal MP Nicolle Flint revealed her intention to quit politics.

Ms Flint announced she won't recontest the next election in an email sent to her constituents last night.

No reason was given by Ms Flint as to what prompted the surprise move out of politics, but speaking today Mr Birmingham implied that ongoing "harassment and bullying" faced by Ms Flint led to her decision not to face another election campaign.

"She faced a very bitter election campaign last time, that she saw appalling behaviour against her," he said.

A fellow South Australian, Mr Birmingham said he and the Prime Minister had worked to support Ms Flint during the harassment, "unfortunately, we can't control the actions of the political campaigners".

The Liberal MP has had her offices repeatedly vandalism with offensive language and has been harassed on social media by GetUp, Extinction Rebellion and other left-wing groups, Mr Birmingham said.

In one incident during the bitter 2019 election campaign which Ms Flint later described as "the scariest of her life", the police became involved after she was stalked and photographed by a man and had her office vandalised with graffiti calling her a "prostitute".

As recently as earlier this year, Ms Flint's South Australian offices were again graffitied.

"I think that the Extinction Rebellion activists and others who have continued attacks on Nicolle and others should have thought about the consequences of their actions," Mr Birmingham said.

In announcing her plans to leave politics, Ms Flint said she plans to continue advocating for the people of Boothby until the next election and will support her successor.

"I will work to support the candidate who is pre-selected by our Liberal party members to ensure we return a Liberal government, led by Prime Minister Scott Morrison, to guide our nation to out of the Covid-19 pandemic and beyond," she wrote.

Ms Flint was first elected to Government in 2016 for the seat of Boothby and just scraped through with re-elected in 2019.

More human remains have washed up on the southern NSW coastline, days after the foot of missing Sydney woman Melissa Caddick was found by campers on the South Coast.

Police were called to Mollymook Beach, 60km south of Nowra, late last night after members of the public discovered the remains.

There is currently no indication as to whether the remains belong to Ms Caddick but DNA testing is underway.

The beach is over 200km north of Bournda National Park near Tathra, where three teenagers found a shoe containing the remains of a human foot on Sunday.

Those remains were yesterday confirmed as belonging to Ms Caddick.

Officers identified the shoe as being the same to a pair Ms Caddick was wearing during raids on her home prior to her disappearance.

If confirmed as belonging to Ms Caddick, the latest discovery would add more weight to the theory that the Sydney businesswoman's remains were carried south down the coastline from Sydney by drifting currents.

Offshore drift modelling found that a body which entered the water near Ms Caddick's home in Dover Heights in Sydney may have drifted to the South Coast over time.

Ms Caddick, 49, disappeared on November 12 last year after leaving her home for what her husband believed was a morning run at 5.30am.

She and her family lived in affluent Dover Heights in Sydney's eastern suburbs.

She had been under investigation for allegedly running a Ponzi scheme, using millions from investors to make lavish personal purchases.

The Australian Federal Police (AFP) raided her home as part of an ASIC investigation the day before she disappeared.

The family of an 82-year-old Gold Coast man charged with murdering his wife has offered him their "unwavering love and support".

Maxwell Beever is accused of killing his wife Robyn in their home in Varsity Lakes, where her body was found on Thursday afternoon.

He was taken to Gold Coast University Hospital where he remains in a stable condition under police guard.

Mr Beever is "not in good health, and has not been for a number of years", his family said in a statement issued through their lawyer.

"Robyn and Max met when they were just 20 years old, and they have been together as a loving couple ever since, for more than 60 years.

"They were devoted to each other and, in their later years, the primary concern of each of them very obviously was the welfare of the other.

"Naturally, their family has been absolutely devastated by this entirely unexpected and deeply tragic turn of events, and in particular the awful loss of their mother.

"But their greatest concern now is for their aged father, who is not in good health, and has not been for a number of years.

"He has their unwavering love and support, and they are fully committed to his welfare."

The family asked for the press and the public to respect their privacy " to allow them to absorb and cope with the enormity of this unfolding tragedy".

They thanked those who had offered their sympathy and support.

Mr Beever has been charged with the murder of his wife.

Speaking at a press conference yesterday morning, Queensland Police's Detective Inspector Chris Ahearn said Mr Beever "doesn't have any significant physical injuries" but has undergone toxicology testing.

Detective Inspector Ahearn said the elderly man is "in a distressed state" and has refused to be interviewed by police.

He declined to detail any medical conditions the 82-year-old may have, but said "the physicality of that gentleman is something that continues to be under investigation".

He noted that the toxicology results would likely "give us a clearer picture on what might have gone on".

Neither Mr Beever nor his wife have any criminal history and this is the first time they have had formal contact with police.

Detective Inspector Ahearn said it is believed Ms Beever likely died on Thursday, or possibly as far back as 6pm the night before.

Detective Inspector Ahearn has called for anyone who was in the area during that time to come forward, especially anyone who may have heard anything that may assist investigators.

He described Ms Beever's death as "a tragic incident with a tragic outcome".

"Our thoughts go out to the family and friends of this woman," he said.

No application for bail was made and the matter was adjourned until next March 5.
