How European countries could use Covid-sniffing dogs to reduce infections

Scientific trials in several European countries have found that trained dogs can accurately detect coronavirus in human sweat, opening up a new path for faster and cheaper preliminary Covid screening in all kinds of places.

With a sense of smell that's 10,000 to 100,000 times better than ours, it's no surprise that numerous trials have shown that dogs are capable of accurately detecting if a person has Covid-19 in 95 percent of cases.

Scientific teams across Europe are now training pooches to see how much they can finetune their sense of smell to Covid-19 (without them coming into direct contact with it), in the hope that sniffer dogs can become a mainstay at schools, stadiums, airports and other public places.

So far, there are reports of succesful trials in France, Germany, Austria, Spain, Italy, Finland, Belgium and the Czech Republic.

This quick and cheap preliminary screening method has the potential to cut costs, save lives and help countries with a limited lab testing capacity.

Reader Question: Can I get a third Covid booster shot in France?

As France launches its autumn vaccine campaign, almost half of those eligible for the second booster jab in France have already received it. This has left some wondering whether they could qualify for a third booster, using the new dual-strain vaccines.

Reader Question: Can I get a third Covid booster shot in France?

Question: I’m in my 70s and I had my second booster back in the summer but now I see that the new dual-strain vaccines are available – should I be getting an extra booster with the new type of vaccine?

French health authorities launched the autumn booster campaign on October 3rd includes newly authorised dual-strain vaccines – such as the Pfizer/BioNTech vaccine adapted to BA.1, the Moderna vaccine adapted to BA.1, and the Pfizer/BioNTech vaccine adapted to BA.4/5 – which are designed to combat the Omicron variant.

It will be followed by the seasonal flu vaccination campaign in mid October.

In France, about 6.3 million people have received a second booster dose, “or 41 percent of the eligible population,” said the Directorate General of Health (DGS) to Ouest France.

Currently only those in high risk groups are eligible for a second booster shot, including pregnant women, the elderly those with medical conditions or carers – find the full list here.

As almost half of the eligible population have already received a fourth vaccine, many are wondering whether they will be eligible for a fifth (or third booster) in order to access the new dual-strain vaccine.  

According to Virginie, a representative from HAS – France’s health authority – the organisation “no longer thinks in terms of doses for high-risk people and immunocompromised patients.”

Specifically, the HAS recommends that a new injection be given – and if possible one of the dual-strain vaccines – “regardless of the number of injections received up to now”.

However, French health authorities specified that the additional booster should “respect the minimum recommended time between two doses.”

“This depends based on your profile – for people aged 80 and over, residents of nursing homes or long-term care units (USLD) and those who are immunocompromised, the wait-time is three months between jabs. For the others, the delay is set at six months.”

For those who have already been infected by Covid-19, the HAS recommends that if you are eligible for a second (or third booster) that the additional dose “is still recommended, with a minimum delay of three months after infection.”
