As Denmark enters into a key phase of its COVID-19 vaccination program, some good news has filtered through from the tech industry.

Dragør-based firm RobinTech has developed a new method that can optimise vaccine doses.

More specifically, it allows health workers to extract seven doses out of Pfizer’s COVID-19 vaccine instead of six.

RobinTech estimates it will increase Denmark’s COVID-19 vaccine capacity by 270,000 vaccinations for April and May alone.

The method employs a vaccine container, a syringe and a smartphone to enhance how the doses are drawn from the vials.

It does so by controlling the air intake in the vial, its angle during extraction, and from where the vaccine is drawn from.

Could work for all vaccines
Currently, RobinTech is in negotiations with Statens Serum Institut and the Capital Region regarding the possibility of rolling out the method nationwide.

“When testing in the vaccination centres, they have not been able to get seven doses out of the vial at any point,” Martin Vesterby, the head of RobinTech, told TV2 News.

“But the same people have managed to get seven doses every time with our solution.”

Vesterby went on to say that the method has only been tried with the Pfizer vaccine, but in theory it could be used for all vaccines. 

It takes about an hour to train health personnel to use the method.

A survey carried out by Megafon for TV2 has found that 71 percent of parents have handed over children to daycare in spite of them being sick.

Moreover, 21 percent of those surveyed admitted to medicating their kids with paracetamol, such as Panodil, before sending them to school.

The FOLA parents’ organisation is shocked by the findings.

“I think it is absolutely crazy. It simply cannot be that a child goes to school sick and plays with lots of other children. Then we are faced with the fact that they will infect the whole institution,” said FOLA chair Signe Nielsen.

Pill pushers
At the Børnehuset daycare institution in Silkeborg a meeting was called where parents were implored not to bring their sick children to school.

At Børnehuset there are fears that parents prefer to pack their kids off with a pill without informing teachers.

“We occasionally have children who that they have had a pill for breakfast,” said headteacher Susanne Bødker. “You might think that it is a Panodil more than a vitamin pill, if it is a child who has just been sick, for example.”

Parents sick and tired
Parents, when confronted, often cite pressure at work as a reason for not being able to stay at home with their children.

Many declare that they simply cannot take another day off, as they are afraid of being fired.

Allan Randrup Thomsen, a professor of virology at KU, has heavily criticised the parents’ actions, describing the current situation as a “vicious circle”.

“It promotes the spread of viruses, and it adds momentum to a cycle where parents are pressured by high levels of sick-leave. If they then choose to send the children to daycare while they are still recovering, they keep the epidemic going in daycares, and this in turn puts a greater burden on the parents.”
