What is the connection between Long Covid and Terry Davis?
Terry Davis adored physicsgirl. He would have been sad that she was sick, and happy she got better.

I was vaccinated and boosted, ended up catching covid 3x so far.
Now, hop in your time machine and do the A/B test.
Intramuscular vaccinations do not significantly prevent infection of the upper respiratory immune compartment (mucosal IgA antibodies, not humoral covered by IgG). The efficiency against infection by sars-cov-2 is about 20%. That means 80% get infected.
Now, the intramuscular injection vaccines do provide tissue resident B (+IgG antibodies) and T cells in the body serum (humoral, not mucosal) immune compartment and this has been proven to prevent serious (hospitalization) by covid-19 with decent (>50%) efficiency. These IgG antibodies do not seep into the upper respiratory (mucosal compartment) and provide protection there though; only the lower lungs.
But infection? The only good mitigation, lacking a proper intranasal vaccine like India has, is wearing a well fit and sealed mask like an N95 with good practices.

Some people have high levels of COVID-19 spike protein, long after main infection is gone. There is very easy way to test for it. Some retroviruses like HIV are able to modify DNA, and embed themselves into cells permanently. Perhaps COVID-19 is doing something similar! It would be nice to do DNA scan, for sequences that produce spike proteins, on people with long COVID symptoms!
Yep, something like spike protein that is more persistent than usual may provoke an inadequate immune response in the body, which is known to cause clotting, which is known to cause tissue hypoxia, which, in turn, is known to induce a mitochondrial dysfunction, starting the vicious cycle of pathology. Chicken and Egg dilemma. We have a lot to discover and formalize. I do not say that you are not right, your suggestio…
Sadly long-covid research is very underfunded. Doing a few thousand DNA tests is not that expensive.

Infection isn't the only concern.
Severity of disease course is a consideration.

It's interesting to me how COVID vaccine skepticism has persisted so long despite the evidence the vaccine was safe and effective. All the nightmare scenarios and long-term side effects people speculated about never happened and more and more doses of the vaccine have been taken safely.
A close family member has permanent heart failure caused by the first Covid booster.
They now go to the top heart hospital in the world.
The doctors there say that while nothing can be proven for certain - obviously - the timing of their booster and the onset of their heart symptoms and the fact that there was no indication they had Covid at the time all point to the high probability it was the vaccine.
And they’ve seen this in other patients.
The scary thing is that this person had symptoms of heart failure for months before going to the ER and if they hadn’t, would have probably just died in their sleep long after getting the shot and it would have been a mystery, chalked up to bad luck and age.
Ironically, their current status with heart failure puts them in a high risk group and the recommendation is that they keep getting Covid boosters. The logic here is that the chances of getting another bad reaction from the vaccine is overruled by the chances they’d die from severe Covid.
It’s not as cut and dry as people on either side of this debate want to make it.

#198We already had deeply insightful discussions on this topic here, but I will repeat for new HN people. Covid-19 tends to cause post-viral complications, which manifest themselves as chronic fatigue, body temperature dysregulation, air hunger / shortness of breath with SpO2 of 99%, various neurological symptoms: pain/tingling/numbing sensations in the extremities, parosmia (a distorted sense of smell), parageusia (a di…
There has been no such collective conclusion. It could be correct and there are several viable hypotheses in there worthy of further research but nothing that meets the standards of evidence-based medicine.

This might be an ignorant question, but are these therapies likely to help chronic fatigue that predates Covid-19?

> "its in your head" insane that it's still so common...
In my mind, that doesn't make the symptoms any less real to the person suffering from them and does absolutely nothing to remedy the situation. Even if it is in the person's head, any doctor offering that advice should be facing consequences for not offering a legitimate path for treatment.
Many conditions aren't well understood and simply don't have effective treatments.
