On February 16th 2024 Wendy and I set-forth on a 20 day trip, revisiting old haunts in SE Asia.
From Hong Kong we made a brief side-trip to Shenzhen in China then embarked on a Cruise, sailing down the east coast, south, to Singapore where we spent a few days, before returning home: [Hong Kong; Ha Long Bay/Hanoi; Hoi An; Ho Chi Min City (Saigon); Bangkok; Ko Samui; Singapore]
In April 2010 we travelled to the previous French territories of Cambodia and Vietnam: ‘French Indochina’, as they had been called when I started school; until 1954. Since then many things have changed. But of course, this has been a region of change for tens of thousands of years. Our trip ‘filled in’ areas of the map between our previous trips to India and China and did not disappoint. There is certainly a sense in which Indochina is a blend of China and India; with differences tangential to both. Both have recovered from recent conflicts of which there is still evidence everywhere, like the smell of gunpowder after fireworks.
I grew up in semi-rural Thornleigh on the outskirts of Sydney. I went to the local Primary School and later the Boys' High School at Normanhurst; followed by the University of New South Wales.
As kids we, like many of my friends, were encouraged to make things and try things out. My brother Peter liked to build forts and tree houses; dig giant holes; and play with old compressors and other dangerous motorised devices like model aircraft engines and lawnmowers; until his car came along.
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.
