A common symptom of Covid-19 is anosmia (loss of the ability to smell) which suggested to some that the virus could get into the brain. More recent evidence seems to bear this out, although there is still a lot of speculation.

Pfizer-BioNTech are making a mRNA vaccine, but what is that?
Covid-19 blog for the non-expert The Pfizer-BioNTech vaccine for Covid-19 is all over the media. What hasn’t been in the headlines so much, is that this is a mRNA vaccine and if successful, it’ll be the first of its type. Some say they will not take it because it’s “rushed” but this misses the pointContinue reading “Pfizer-BioNTech are making a mRNA vaccine, but what is that?”
90% effective Covid-19 vaccine
The headlines are jubilant with “Covid-19” vaccine 90% effective. As one of those skeptical scientists, I’m in a difficult position because I don’t want to dampen any hope, but at the same time it’s worth questioning the headline to see what’s really behind it. The announcement was from Pfizer and BioNTech, and the media areContinue reading “90% effective Covid-19 vaccine”
New Covid-19 tests
A Covid-19 blog post for the non-expert We’ve been hearing how the UK government wants to return to normal life under its £100bn Operation Moonshot Covid-19 testing programme. Headlines such as those in the Daily Mail have proclaimed “Prospect’ of 10-minute ‘rapid turnaround’ Covid tests” but others including the BMJ are not so sure. I thought,Continue reading “New Covid-19 tests”

A blog post for the non-expert Our best hope against Covid-19 is an effective vaccine, and efforts in that direction are galloping along like no other time in history. There are so many vaccines being investigated, it’s hard to keep up with the numbers, but at the time of writing there appear to be wellContinue reading “What is interferon and is it effective against Covid-19?”
Covid-19 was genetically-engineered
A Covid-19 blog post for the non-expert The story that Covid-19 is a genetically-engineered virus from a Wuhan laboratory has gone viral across the internet (dated pun intended). President Trump implied it, and the Daily Express ran a 10th March headline, “Coronavirus may have been genetically engineered for the efficient spreading in the human population,Continue reading “Covid-19 was genetically-engineered”
A sober look at dexamethasone
A Covid-19 blog post for the non-expert It stared with a 16th June 2020 press release from the University of Oxford “Low-cost dexamethasone reduce death by up to one third in hospitalised patients with severe respiratory complications of COVID-19” – which triggered the equivalent of a media cytokine storm (pun explained shortly). I do not want,Continue reading “A sober look at dexamethasone”
Has the scientific method been suspended?
There’s a scene in the Netflix series Space Force when Chief Scientist Dr. Adrian Mallory asks, “why do you distrust scientists?” To which General Naird angrily replies, “you scientists say don’t eat carbs one day and only eat carbs the next”. One of the scientists in the room interjects, saying, “because of the sample sizesContinue reading “Has the scientific method been suspended?”
Broken Clock Fallacy
I had a terrible bout of flu in November. In fact, my wife said she’d never known me so ill. I had a fever that went up and down, aching joints, a prolonged dry cough and found it hard to breath when laying down at night. I have an oxometer which occasionally dipped below 90%Continue reading “Broken Clock Fallacy”
A scientific tightrope
The two most senior scientific advisors to the UK, Sir Patrick Vallance (Chief Scientific Advisor) and Professor Chris Whitty (Chief Medical Officer) have come into a lot of criticism recently for failing to say what they really believe regarding the Government’s response to the Covid-19 outbreak. As Civil Servants they are meant to be impartialContinue reading “A scientific tightrope”
