better article from a more legitimate source where they clarify explicitly not a gain of function experiment, and contrary to OP's headline, did not make the virus more contagious or deadly. From what I understand, put in plain terms, they combined 2 strains of the virus in order to prove that it was not the spike protein that made omicron more deadly.

Wooo! Science!! I can do science, me
Appreciate the additional source, but they objectively created the most contagious and deadly strain of Covid by chimerically combining a strain that was highly contagious with another one that had a high death rate. We already know that Covid strains could mutate to become be even worse than what we’ve seen, so this experiment does nothing except risk another pandemic and millions of deaths. It should never have been done and shouldn’t be defended.
Yeah, yeah, but your scientists were so preoccupied with whether or not they could that they didn't stop to think if they should
Ahh a fellow Chaos theorist lol

Gain of function is not limited to lethality. It could have killed 20% fewer mice but spread 300% more efficiently, as omicron did.The article doesn't mention if they gaged the spread.
Interesting. Thanks for explaining. Still seems to fall way short of creating “the most contagious and deadly strain of covid” as suggested above, but I do appreciate that explanation.
You overlooked the fact that they did made the Omicron strain more deadly. Omicron is MUCH more contagious than the original strain, but also less deadly. By combining super contagious Omicron strain with the deadly original strain, the combined chimeric strain has the worst of both worlds: high contagion and high mortality rate. It would potentially kill more people than any strain we have encountered so far.
Total deaths = Contagion rate * mortality rate * population (rough math)
The new strain would cause more deaths than either of the original strains would have caused. We benefit nothing by creating the worst possible strain of Covid in a lab, and risk everything.
Ah, and the spike protein is what causes the increase in contagiousness. Gotcha. Thank you.
Apart from the fact that the article itself says that it has a lower mortality rate than the original one and that those data refer to mices (which makes all the possible difference), as it's obviously not possible nor sensi Al to experiment on humans. Bio and pharm fields require experiments like this one all the time, which can be counterintuitive for people from outside. I'm not really following this exact case, as I don't have time to properly read the paper, but it's likely been done because this will help knowing better some cellular mechanisms, or could be used to develop better vaccines / antivirals... You can be safe knowing that it's a common practice and people who work on that knows how to handle samples. The founds are low enough to not waste them on something unless it's undeniably useful
No, no they did not “objectively [create] the most contagious and deadly strain of COVID ….” The strain they created had an 80% kill rate in mice while the original had a 100%. This was done in a level 3 lab, has already been done in other labs, and was performed to help determine why Omicron is evading vaccines. Adding the original spike back in proved that the change in the spike protein is not what is making Omicron and it’s variants more effective at evading immune response among the vaccinated (as was originally posited). This experiment allows vaccine developers to reformulate their bivalent vaccine in a way that is more effective at protecting against the Omicron variants. Your fearmongering and hyperbole do not help with anything.
“When mice were infected with just the original, ancestral virus strain, 100% of the mice died.” Yet when infected with this new strain, only 80% of them died. This strain is less deadly than the original.
The spike protein if I’m remembering right is what decides how infectious a Covid strain is. If they wanted to make a truly fucked strain they would of combined the infectious ability of Omicron, which is not the more deadly strain as it attacks the upper respiratory system predominantly, and combined that with Delta. Delta was murdering people. It went for the lower respiratory destroying lungs.
Delta also had an extremely fast and high viral load that would build up in people in just a few days. Likely that is what prevented it from being worse spread and becoming the dominating strain which would of killed a much larger amount of people.
People are still reading Fox News like it's a legitimate source for science news (and pandemic news in particular). Ugh...
Thank you for this. I got a little worried when Fox News was being used as the source.
Thank you for legitimate sources
Thought Omicron was less deadly, more contagious. Was told this was the natural evolution of viruses. Was I mislead?
You’re correct, becoming less lethal and more contagious is the natural evolution of viruses, but this isn’t natural, this is artificial.
Naw they meant Delta. Had Omoincron twice now and it’s much easier. Had Delta once and got lung damage and my dad died.
Omicron being less deadly seems correct based on what is presented in the article. The ancestral virus strain had 100% mortality. Ancestral virus + omicron spike protein had 80% mortality. Omicron strain had mild symptoms.
Sure, they created the most deadly strain of coronavirus known to man in the lab and it's not "gain of function". Whatever it is, it needs to be banned and the researchers need to be arrested and sent to prison for a VERY LONG TIME for endangering the human population.
OK sure buddy

So yeah that makes a big difference. Just a few words.
But who trusts newspapers?/s
