Since last year, I have taken a deeper interest in malnutrition and food poverty both here in the UK and across the world. One thing I noticed was that the image of malnutrition is often… More
- 1938: a tape recorder was used for the first time to send a radio broadcast
- 1743: Antoine Laurent Lavoisier was born. He is considered to be ‘the father of modern chemistry’ and is responsible for naming oxygen and determining what role it plays in combustion and respiration.

Researchers in the UK have found that the protection offered by the Pfizer/Biotech and AstraZeneca vaccines begins to fall after six months. The researchers have linked this to the need for booster shots for those who already had two doses of the vaccine.
While major countries like the US, UK and also the EU are planning to administer booster shots, there has been some criticism and scepticism. Some researchers believed there was no evidence that booster shots were necessary. Some also believe it would be morally wrong to start giving people a third dose many people are unable to access the vaccines at all.

There are three stages in scientific discovery. First, people deny that it is true, then they deny that it is important; finally, they credit the wrong person.

I like to post quotes that resonate with me from time to time and this:
It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.
…caught my eye. It was attributed to Darwin, and I had no reason to believe he didn’t say it. The variations in the quote were probably a flashing neon sign that I didn’t see. Something compelled me to look up the quote online and it turns out it’s a misquotation.
One so prominent, it was featured in the California Academy of Sciences (until they removed the Darwin mention).
The real quote seems to be from Leon C. Megginson, Professor of Management and Marketing at Louisiana State University at Baton Rouge. While the quote itself is a good one, it is a lesson in knowing when to fact check and research (hint: ALWAYS!) – something I will do for all quotes I post in future.
Face masks have become part of our new normal over the past year both indoors and outdoors. While they’re highly recommended inside heavily populated areas like supermarkets/grocery stores and public transport, there’s not much guidance when it comes to outside.
According to Monica Gandhi, MD, MPH, the risk of catching COVID-19 outside is quite low.
“The risk of outside transmission is very low because viral particles disperse effectively in the outside air. A study in Wuhan, China, which involved careful contact tracing, discovered that just one of 7,324 infection events investigated was linked to outdoor transmission. In a recent analysis of over 232,000 infections in Ireland, only one case of COVID-19 in every thousand was traced to outdoor transmission. And a scoping review from the University of Canterbury concluded that outdoor transmission was rare, citing the opportunity costs of not encouraging the public to congregate outdoors. Overall, transmission is around 5000 times less likely to happen outside than inside.” (Posted April 27, 2021)

… so, does that mean that we ditch our face masks and get some fresh air? With the vaccination programmes across the world coming along more efficiently and effectively we’re edging closer and closer to that point.
However, until it’s fully safe to do otherwise, we should all continue to maintain social distancing when around people who aren’t in our households, support bubbles or friendship groups.
The quote is taken from Sciline’s ‘Quotes From Experts‘.
Torture the data and it will confess to anything, as they say at Guantanamo Bay.
Bad Science, Ben Goldacre
This quote is somewhat amusing but very much true of some research carried out. It’s not just limited to science either. How many times do less than reputable sources cherry-pick data and use it to support a conclusion that isn’t correct?
Particularly nowadays with the internet being an open house in terms of the information availability. Researchers must handle data with great care and avoid the temptation of moulding it to fit their hypotheses or narratives.
EMA’s safety committee (PRAC) concludes that the benefits of the #COVID19Vaccine AstraZeneca still outweigh its risks despite possible link to rare blood clots associated with low levels of blood platelets.

The EMA safety committee held a meeting on 18th March and found that:
- the benefits of the vaccine in combating the still widespread threat of COVID-19 (which itself results in clotting problems and may be fatal) continue to outweigh the risk of side effects;
- the vaccine is not associated with an increase in the overall risk of blood clots in those who receive it;
- there is no evidence of a problem related to specific batches of the vaccine or to particular manufacturing sites;
- however, the vaccine may be associated with very rare cases of blood clots associated with thrombocytopenia, i.e. low levels of blood platelets (elements in the blood that help it to clot) with or without bleeding, including rare cases of clots in the vessels draining blood from the brain (CVST).
The full report of the meeting can be found here.
Several countries across Europe have suspended the AstraZeneca vaccine due to safety concerns. There have been reports of blood clotting and deaths in people who have been administered the vaccine.
In comparison, there seems to be little trouble with the rollout of the vaccine in the UK with scientists there insisting that the jab is safe.
What happens next?
The European Medicines Agency is currently reviewing the issue, along with the Moderna and Pfizer-Biotech vaccines which have also been linked to blood clotting. The EMA executive director, Emer Cooke, said:
There is no indication vaccination has caused these [blood clotting] conditions.
However, like with any form of medicine, we will only find the answers through continuous testing.
Currently, WHO has stated that it is safe to continue using the AstraZeneca vaccine and indications are that the suspensions may not last, particularly in Europe where some countries are experiencing a third wave of infections.
16th March 2021:
WHO is investigating the reports and working closely with the European Medicines Agency.
As soon as review of the data is finalized, we’ll inform the public of any findings.
For the moment, the European Medicines Agency’s position is that the benefits of the AstraZeneca vaccine in preventing COVID-19, with its associated risk of hospitalization and death, outweigh the risks of side effects.
WHO’s Global Advisory Committee on Vaccine Safety (GACVS) is meeting today to review the reports of rare blood coagulation disorders in persons who had received the AstraZeneca vaccine.
On This Day, Albert Einstein was born. Born 14 March 1879 in Ulm, Württemberg, Germany, Einstein was a renowned physicist who developed the special and general theory of relativity.
He is, perhaps, one of the most influential scientists of the 20th Century, with his work continuing to have an impact even today (without his breakthroughs, technology such as the computer, television and music players would not have existed).
Einstein was also partial to dropping some notable insight, much of which exists in the form of quotes posted all over the internet.
My personal favourite (and one I need a constant reminder of) is:
If you can’t explain it to a six-year-old, you don’t understand it yourself.
