Oxford vaccine regulatory authorisation: FAQ | Research | University of Oxford

People have been asking a lot of questions that are addressed in this article from the Oxford-AstraZeneca vaccine makers (last December); in particular, I found this informative para about the length of time between the two doses:
The authorisation is recommended as a two dose regimen, given as two standard doses with a flexible inter-dose interval of four to twelve weeks, which was shown in clinical trials to be safe and effective at preventing symptomatic COVID-19, with no severe cases and no hospitalisations more than 14 days after the first injection.

Foreign NHS workers could be denied Covid vaccine in England | World news | The Guardian

Foreign NHS workers treating Covid patients are at risk of being denied vaccinations because of internal guidelines about who can receive the jab, the Guardian has learned.
Documents circulated among staff at one leading hospital show vaccinators have been told they must not immunise anyone without an NHS number.
Shameful! At least in some cases, they're vaccinating people who currently have no NHS number and then registering them later. These people are often front-line workers who MUST have the vaccine.

How effective is a single vaccine dose against Covid-19? | BBC Future

Pretend it didn't happen – expert advice on how to behave after receiving a single dose of any of the Covid-19 vaccines.
When it's claimed that a single dose of a vaccine is 97% effective, what does that mean? No, I had no idea either, because no one has explained it adequately. This article explains. Whether it does so adequately or not kind of depends on you. If you get your first dose of the vaccine and stay indoors for two weeks, then it probably has.

Covid: How a £20 gadget could save lives | BBC News

One of the mysteries of Covid-19 is why oxygen levels in the blood can drop to dangerously low levels without the patient noticing.
It is known as "silent hypoxia".
As a result, patients have been arriving in hospital in far worse health than they realised and, in some cases, too late to treat effectively.
But a potentially life-saving solution, in the form of a pulse oximeter, allows patients to monitor their oxygen levels at home, and costs about £20.
You don't need any medical training to use one, either. You just put it on the end of your finger and turn it on and wait. In a few seconds, it should give you a reading of somewhere between 95 and 100 if you're healthy.

Researchers warn of another Covid spike if people mix after vaccine | World news | The Guardian

Behavioural psychologist says many people mistakenly think they are safe as soon as they receive jab
I'm pretty sure that most people on Diaspora* aren't stupid, and won't just get their vaccination and go out and party. But I'm posting this in case you know some people who are likely to do just that.

1) The vaccination isn't fully effective until something like two weeks after you have it, and that might depend on which vaccine it is.

2) Someone coughs near a shelf in a supermarket. You pick up a carton of milk and transfer virus onto your hands. On the way out of the supermarket, you touch a door handle. Someone else touches the door handle and now they've got the virus. Even though the virus is mostly transmitted by aerosol, there is still a possibility of transmission by other means.

3) Just because you're vaccinated, doesn't mean you can't pass it on. If you breathe it in, your immune system might kill it off, but not necessarily before you've coughed it onto someone else.

You still need to wash your hands a lot. You still need to refrain from touching your face. You still need to keep about 6 feet between you and most other people. At least, until we're all much safer.

Don't mean to preach. It's just that, even a year down the line, there are still people who apparently don't know what's going on.

COVID-19: Disruption to vaccine rollout as people trek for miles in snow for jabs - and others told to stay at home | UK News | Sky News

The disruption to the vaccine rollout comes after parts of the North saw snowfall overnight and more is forecast later today.
But, of course, the government planned in advance for the bad weather. Didn't they? Doesn't look like it. The UK pays an obscene amount for the upkeep of military forces. Can they not be deployed to affected areas?

On another D* thread, someone questioned the slow rollout of the vaccine. I said that, here in the UK, I can't tell the difference between the Tory government's gross incompetence on the one hand, and deliberate pursuit of a herd immunity strategy on the other.

You May Soon Be Able to Measure Blood Pressure From Your Finger

Wearable devices have become more sophisticated in recent years, with the ability to track everything from abnormal heart rates and atrial fibrillation to stress and even blood oxygen levels. However, monitoring blood pressure is a challenge for a wrist-worn device. Wearable components maker Valencell says it’s figured out how to measure blood pressure using photoplethysmography (PPG) heart rate sensors from your finger or wrist.
Apple has already filed its own patent on measuring blood pressure with an Apple Watch. It will be interesting to see how quickly this technology comes to market.

The Pandemic Could Disrupt Decades of Decline in Cancer Mortality | Gizmodo

A new report released Tuesday by the American Cancer Society provides some good news: Americans who had cancer in 2018 were less likely to die from it than they were a year earlier, continuing a steady decline in cancer mortality over the past 30 years. As hopeful as this trend is, though, there are still lower survival rates in different parts of the country and among Black Americans. Experts also worry that the covid-19 pandemic will end up erasing some of this progress.

Here’s What to Know About the Universal Flu Vaccines Being Studied | weather.com

One main reason humans need to get a flu vaccine annually; flu strains mutate regularly so vaccines need to be slightly altered every year. During past flu seasons, the CDC has noted a vaccine effectiveness range between 40-60%, and a reduced the risk of flu-related illness by 40-60% within the overall population.

There are, however, several “universal” flu vaccines currently being studied that aim to make annual flu vaccinations a thing of the past.

Alzheimer's: the 'switch-on moment' discovered | The Conversation

The past three decades saw a dramatic improvement in our understanding of what brings about Alzheimer’s disease. Two proteins are thought to be responsible: amyloid and tau. The most widely accepted theory is that a critical level of amyloid in the brain triggers the build-up of the more toxic tau protein. This has led to several studies testing drugs and vaccines that remove amyloid and tau to see if they can improve or even prevent dementia. Results have been disappointing.
But the hunt is on for new tests.

Covid Pandemic: Microbiomes Could Be Key to Stopping Spread of Future Viruses - Bloomberg

In the Western world, humans spend 90% of their time indoors. The average American spends even more than that—93%—inside buildings or cars. For years scientists have sounded the alarm that our disconnect from the outdoors is linked to a host of chronic health problems, including allergies, asthma, depression, irritable bowel syndrome, and obesity. More recently, experts in various fields have begun studying why buildings, even those designed to be as germ-free as possible, are vectors for disease, not the least Covid-19.

Biomarker of Alzheimer's found to be regulated by sleep cycles | New Atlas

Scientists at Washington University School of Medicine (WUSM) in St. Louis have spent some years investigating the links between circadian rhythm and Alzheimer’s, and have recently been making some real inroads. Following a 2018 study demonstrating how disrupted sleep can accelerate the buildup of toxic plaques associated with the disease, the team has now identified a protein implicated in the progression of the disease that appears highly regulated by the circadian rhythm, helping them join the dots and providing a potential new therapeutic target.

Covid blood test can predict patient survival chances | Coronavirus | The Guardian

A blood test has been developed that can predict whether Covid patients will need intensive care – or are even likely to survive – shortly after they develop symptoms.
If validated in real-life hospital settings, the test could enable doctors to direct life-saving treatment to the most needy patients sooner, boosting their chances of survival. It could also bolster doctors’ confidence in the face of difficult decisions, such as whether to offer palliative care or an ICU bed when hospitals are close to capacity.
