Education Part II : Leaps in scientific understanding ! - ketchim - 01-10-2021
In January 2020, two scientists published the entire genetic code of a coronavirus
that was soon to wreak havoc around the world.
It marked the start of a year of intense and rapid scientific endeavour
to work out how we might fight the virus.

Eddie Holmes had the genetic blueprint for the coronavirus in his possession
for exactly 52 minutes before he put it online.
Prof Holmes is based at the University of Sydney, where he works on the emergence of infectious disease -
an area of research that was suddenly thrust into the spotlight at the beginning of 2020.
He has worked closely, for several years, with Prof Yong-Zhen Zhang
who was at the Chinese Centre for Disease Control in Beijing.
Prof Zhang sequenced the genome of the virus that closed down the world.

He collected samples taken from some of the first patients in Wuhan Central Hospital
where a cluster of mysterious pneumonia cases had emerged.
Many of those patients had a link to a seafood and wildlife market in Wuhan.

When he examined the code, Prof Zhang immediately saw that this was a coronavirus.
It looked very similar to Sars -
the respiratory disease that caused a deadly outbreak in Asia in 2002.
"That was on 5 January," recalls Prof Holmes.
"And we just thought, oh no. It's Sars back again."

But this code - this virus - was different. It was new.

On 11 January Prof Holmes phoned his colleague in China
and asked his permission to publish the sequence.
"Zhang was on a plane, strapped into his seat," Prof Holmes recalled. "He told me he needed to think about it
- there was some pressure not to release too much information about the outbreak.
"He called me back about a minute later and said, 'OK, let's do it.'"
A researcher in Prof Zhang's lab emailed the genetic code to Eddie Holmes
"It was about 01:00 there," Prof Holmes recalls.

In the ensuing 52 minutes, the scientists together wrote a brief post explaining that they were
"releasing a coronavirus genome from a case of a respiratory disease from the Wuhan outbreak"
and uploaded the code.

That same weekend, scientists at a US pharmaceutical company called Moderna,
which had never previously brought a product to market, downloaded the genome
and started work on their experimental vaccine.
Scientists at Pfizer did the same (including VS Roopchand, hailing from Guyana)
