Friday 20 May 2022 10:10 PM DR MICHAEL MOSLEY: I've finally got Covid, but I'm tackling it with two ... trends now
After more than two years dodging the Covid-19 bullet, I have been struck down.
This is particularly galling because throughout the pandemic I’ve tried to reduce my risk by avoiding packed places, such as pubs, and wearing a mask on public transport and in shops.
But the cunning virus finally got to me via my wife, Clare. Last week, she came down with classic Covid symptoms (lots of coughing and sneezing) and, a few days later, after futile attempts to avoid each other while living in the same house, I followed her and I’m now racked by frequent bursts of coughing that sound like someone trying to start an old tractor on a cold winter’s morning.
To be honest, I’m not surprised to have succumbed, because the most recent Covid variant, Omicron, is the fastest-spreading virus in human history.
Omicron is much more infectious than earlier Covid variants but, fortunately, it has also mutated into something that is less dangerous.

A study by Imperial College London, involving more than 1.5 million people who’d had either Omicron or Delta, found the Omicron victims were half as likely to end up in hospital or worse.
The study showed that vaccines are saving lives, with people who are fully vaccinated 85 per cent less likely to die from Omicron than someone who isn’t vaccinated.
Although Covid appears to be in retreat, the virus will continue to mutate and almost certainly has more tricks up its sleeve. So what is the next step in our fight against Covid?
Firstly, there are some promising antiviral drugs being trialled — including Paxlovid, which in an early study cut the risk of ending up in hospital by 89 per cent when given within three days of developing symptoms.
And there is a new generation of nasal spray vaccines, which is exciting because research suggests spraying a vaccine up your nose can dramatically cut the risk of transmitting the virus.
This is because the Covid virus typically enters your body via the nose, so if you bolster your nasal defences then you can nip it in the bud. This would have a big impact on how quickly it spreads and how easily it mutates.
Another advantage of nasal vaccines, as demonstrated in animal studies worldwide, is they not only generate lots of antibodies and ‘killer’ T cells, as you would expect from a vaccine, but also immune ‘memory cells’ that hang around in the nose for months.
Researchers from Lancaster University, who were the first to start developing a Covid-19 nasal vaccine in 2020, have shown that two doses of their vaccine, given to hamsters, completely protected them from lung infections and prevented them shedding viruses.
The results were so encouraging they’re planning human trials later this summer. If it works as well as hoped, the idea is that you might simply go along to a chemist and get a spray to use yourself. Because there is no needle, it would be simpler and potentially much cheaper. This should also reassure people with needle phobia.
Meanwhile, what can you do if you get hit by Covid?
If, like me, your symptoms aren’t too bad, the NHS advice is to get plenty of rest, drink water to keep hydrated and take medications such as paracetamol to help with your symptoms. I would also suggest continuing to exercise, if you can. Exercise increases blood flow to your muscles and brain and this increased blood flow, in turn, encourages blood vessels to release virus-fighting immune cells.
There’s a well-worn adage for exercising with infections: if the
