Central Australia

 

 

In June 2021 Wendy and I, with our friends Craig and Sonia (see: India; Taiwan; JapanChina; and several countries in South America)  flew to Ayer's Rock where we hired a car for a short tour of Central Australia: Uluru - Alice Springs - Kings Canyon - back to Uluru. Around fifteen hundred kilometres - with side trips to the West MacDonnell Ranges; and so on.

The Time Lord

 

 

 

For no apparent reason, the silver haired man ran from his companion, shook a tree branch, then ran back to continue their normal conversation. It was as if nothing had happened. The woman seemed to ignore his sudden departure and return.

Bruce had been stopped in peak hour traffic, in the leafy suburban street, and had noticed the couple walking towards him, engaged in good humoured argument or debate.  Unless this was some bizarre fit, as it seemed, the shaken tree branch must be to illustrate some point. But what could it be?

The race for a SARS-CoV-2 vaccine

 

 

 

 

As we all now know (unless we've been living under a rock) the only way of defeating a pandemic is to achieve 'herd immunity' for the community at large; while strictly quarantining the most vulnerable.

Herd immunity can be achieved by most people in a community catching a virus and suffering the consequences or by vaccination.

It's over two centuries since Edward Jenner used cowpox to 'vaccinate' (from 'vacca' - Latin for cow) against smallpox. Since then medical science has been developing ways to pre-warn our immune systems of potentially harmful viruses using 'vaccines'.

In the last fifty years herd immunity has successfully been achieved against many viruses using vaccination and the race is on to achieve the same against SARS-CoV-2 (Covid-19).

Developing; manufacturing; and distributing a vaccine is at the leading edge of our scientific capabilities and knowledge and is a highly skilled; technologically advanced; and expensive undertaking. Yet the rewards are potentially great, when the economic and societal consequences of the current pandemic are dire and governments around the world are desperate for a solution. 

So elite researchers on every continent have joined the race with 51 vaccines now in clinical trials on humans and at least 75 in preclinical trials on animals.
