OK, now even you are calling me names! Wow, really Indah?

How do you understand from my joke that I am calling you names?

You have to opt in someplace or other on the forum, then the threads in the pub will turn up. The rules seem to be like 1850s Wild West but shooting in the back is allowed.

It is mostly occupied by people too old to dive with the sort of views to match. Don’t make the mistake of being reasonable or trying to change minds with facts. The Coronavirus thread has 20k posts I think. Many of the arguments over death rate have been done fairly comprehensively and one or two people there can count. Mostly I find it interesting to see how far wishful thinking can go.

Mmmmm....maybe I give it a pass..Thanks.

Which editorial are you talking about?
The one released 2 days ago from Professor Antonio Bertoletti, an immunologist from the Duke-NUS Medical School in Singapore, and his team? About how some people not infected with covid-19 showed signs of being as result of the common cold being from the same family and sharing same make up? I believe that some of the current vaccines being attempted are also using the common cold as a blueprint for covid-19 immunity

That is not what Bertoletti wrote. He talks only about SARS. Not a common cold: https://www.biorxiv.org/content/10.1101/2020.05.26.115832v1.full.pdf
The second study mentioned in the article reads: The results suggest “one reason that a large chunk of the population may be able to deal with the virus is that we may have some small residual immunity from our exposure to common cold viruses,” says viral immunologist Steven Varga of the University of Iowa. However, neither of the studies attempted to establish that people with crossreactivity don’t become as ill from COVID-19.

It mentions common cold a few times in the study, it's umm kind of the subject matter of the report:
Different pattern of pre-existing SARS-COV-2 specific T cell immunity in
SARS-recovered and uninfected individuals

@Indah the above is the title of the report. Uninfected individuals referring to those uninfected by covid-19 or SARS, but in the report revealed as previously infected with common cold coronaviruses


These latter two T cell specificities were particularly intriguing since the
homology between the two protein regions of SARS-CoV-1/2 and other
“common cold” coronaviruses (OC43, HKU1 NL63 and 229E) was minimal
(Figure 4D), especially for the CD8 peptide epitope. This may suggest that
perhaps not only human “common cold” coronaviruses, but other presently
unknown coronaviruses, possibly of animal origin, can induce cross-reactive
SARS-CoV-2 memory T cells in the general population.
It was remarkable to find that NSP7/13-specific T cells were detected in 9 out
of 18 (50%) SARS-CoV-1/2 unexposed donors, despite the fact that our analysis
was performed with peptides that cover only 10% (684aa) of the ORF-
1 proteome (7096aa). Notably, T cells specific for ORF-1-coded proteins were
rarely detected in our SARS and COVID-19 convalescents

Moreover, a different pattern was observed for NSP7- and NSP13-specific
T cells. These cells were detected in only 3 out of 24 COVID-19 and in 2 out of
23 SARS recovered tested, but were present in 9 out of 18 unexposed donors


@Indah it makes for intriguing reading, about T-cell memory & possibly T-cell vaccine which in theory last a long time as it occurs naturally already in some people previously infected with common cold viruses.
Whereas antibodies for other coronaviruses don't last long, only 3 years range, as opposed to T-cell specific response for many years

Thanks again for sharing link

Th title of the sudy (not peer reviewed yet) mentions only SARS. Different pattern of pre-existing SARS-COV-2 specific T cell immunity in SARS-recovered and uninfected individuals. The second study to which the article refers says: The results suggest “one reason that a large chunk of the population may be able to deal with the virus is that we may have some small residual immunity from our exposure to common cold viruses,” says viral immunologist Steven Varga of the University of Iowa. However, neither of the studies attempted to establish that people with crossreactivity don’t become as ill from COVID-19.

What surprised Bertoletti's team was that 50% of unexposed patients had defensive T-cells which could defend their immune system against the betacoronaviruses SARS and COVID-19. Most likely, the scientists concluded, their immunity developed memory cells from obtaining common colds caused by betacoronavirus or other unknown pathogens.

A ScubaBoard Staff Message...

We are trying to refrain from moving this thread to the pub. Please help us in that endeavor by not insulting each other and by leaving politics elsewhere. It is a virtue to be able to have this discussion while at least giving each other the respect that we each deserve if for no other reason, because we are fellow divers. It's like being on the dive boat together.

Does anybody have 1st hand knowledge of what a Covid-19-free health certificate entails or looks like, in regards for travel to Bali or Indonesia?

 

[Centrals]

A virus free certificate has very limited validity!
It does not give anyone any immunity to infection!
You can pick up the cert and then get yourself infected right away!!!
Same argument for negative tested result!!!

I agree with your logic @Centrals , but at present it's mandatory to obtain virus free certificate to enter Bali going by the information currently available
