A longer interval between first vaccination and booster virtually always gives a better immune response.

Thaks for that Edwina. I get a little annoyed by articles callig Jenner the father of immuology  vaccination, when doctors had been immunising against smallpox for centuaries in China, India and Africa.

COVID-19 / Re: Resurgence Of Covid-19 in Winter....WHY ? What Does 'Winter' have To Do With It

« on: 29/07/2020 16:10:18 »

No need to shout.

In winter windows are closed and there are more people indoors. There are more seasonal colds about. Most people will have insufficient vitamin D levels.

COVID-19 / Re: Why doesn't the UK just repurpose South Korea's COVID-19 app?

This is truly shutting the stable door after the horse has bolted. Early and rigerous seems to have worked in Vietnam. There, they did three level testing for every case, contacts, contacts of contacts and contacts of contacts of contacts. Hanoi carried out 275,000 tests from 114 cases. Seems more sensible than lets enter into the spirit of the pandemic and see how many people we can kill before a vaccine is available.

COVID-19 / Re: Was the Covid-19 coronavirus created in a lab?

The patern seems to be that when something suspicious is pointed out, then the researchers will "find" a corona virus that has a feature which will allay the suspicion. I haven't come to the conclusion that the virus was created in a lab but I think we are past the point where it should be labeled as a conspiracy theory.

14% in a study of about 200 pregnant women in New York... if they regularly attend hospital that could might make the figure unrepresentedly high.

I'd be interested to know what risk is associated with atrial fibrillation, but I don't think that level of detail is available yet. Doctors are at pains to point out that AF is a heart condition, not heart disease, but the media use the two terms interchangeably (although I've never seen a written definition of the difference).

Physics, Astronomy & Cosmology / Re: What does the term 'time' relate to in time dilation?

For the purposes of the OP's question we can say clocks measure rates of change. A quartz crystal on earth would appear to vibrate more slowly if an astronaut could observe it from the space station. And the astronaut would see a quartz clock on earth running slower than a quartz clock on the space station.
