But we haven't "countered" Covid-19 infections. Vaccinated people still get it and transmit it. As the paper clearly states, even mild cases can lead to these "long covid" symptoms.
We have countered Covid in this sense that isolation, maks and vaccines have prevented mass infection, leading to overload on hospitals.
"long-term neuropsychiatric dysfunction (recently characterized as part of “long COVID-19” syndrome) has been frequently observed after mild infection."
And it also says:
"Supporting the hypothesis of astrocyte infection, neural stem cell–derived human astrocytes in vitro are susceptible to SARS-CoV-2 infection through a noncanonical mechanism that involves spike–NRP1 interaction."
So is injecting people with mRNA to produce spike proteins which are known to cross the blood-brain barrier also capable of inducing this mechanism?
We're learning how the virus infects it's host. None of that was known when the pandemic started. Other factors may need to be included, like furin:

The more we know about Covid, the easier it becomes to treat it and maybe find more effective vaccines.
There is a lot we don't know about virii. We know far more about bacteria. When dr. Jenner found the smallpox vaccine, it was by experimentation, not by knowledge. And we don't even know where the virus he used to create the first vaccine came from. It seems vanished.
Your question about crossing the blood-brain barrier is a valid one and it is being studied. But that area is one we know very little about. We don't know how to get medicine into the brain effectively. For that reason, parasites like Toxoplasma gondii have been neglected. That's natural, because you can't study it without putting the patient at great risk. In Jenner's days, there were no ethical committees to prevent physicians from experimenting. Fortunately, we do have these today.
Add to that the likelihood that leaky vaccines led to more mutations and variants which arguably made the disease more persistent than it would have been had we not given these shots to half of humanity.
AFAIK there's no evidence that vaccines have ever made any disease more persistent. Mutations, otoh, are impossible to predict, so how would you measure or test if there are more mutations?
Lyme disease wasn't a result of GoF research. It is long past time to get to the bottom of the origins of Covid question.
According to some Lyme disease was studied by the US military on an island near the place where the first cases occurred. I've never seen proof, of course, but who can tell what the military were doing exactly?
And knowing that the army wasted 20 million US$ trying to find a disease that would only kill people of colour, I wouldn't put it past them.
I would also like to see the reasons why the university of Texas paid 5 million to the Wuhan lab. It seems logical that would be for research they weren't allowed to carry out in the US, wouldn't it?
But I doubt we will ever see answers to these questions. Just like the questions for the labs in Belarus and Ukraine.
