I’m not attempting to troll, just my point of view.
Being a septuagenarian (jg), I do not recall too many ‘Chemistry tests’, maybe when I get much older?
I did have a biochemistry test about 50+ years ago and with pure luck I passed!
“It’s coming from you and nothing is being put into you. No worries about that.”
Totally true. An EVIL car ran over me on my bicycle 20 days hospital, RVN shot in the head... Yes, many punctures of my precious hide, still doing well.
The problem with Convalescent Blood Plasma (CBP) is the possible transmission of the active virus. The doner plasma is injected into the subject.
With traditional vaccines, this is well understood, CBP not so much.
From the abstract Pg 152:
” Notably, the use of pathogen inactivation could guarantee additional safety thus supporting less strict selection criteria”
Pathogen inactivation, still working on that...
Well then you do not understand what convalescent plasma is. Once you've recovered and develop immunity you are clear of the virus. It no longer exists and cannot remain in your system because the antibodies will attack and kill it.
You also don't seem to understand the theory of vaccination, although you are not alone believe me. Perhaps, if I give you a brief overview of how your body develops immunity it may help you and others to understand why a vaccine is far inferior to natural immunity.
When a virus enters your body (let's refer to it as the antigen), it will immediately seek out certain tissue cells to enter. There they begin to replicate and move on to the next cell etc. Your immunity is triggered when enough cells have been invaded for you to begin to have symptoms (threshold). Once your immunity kicks in it battles the invading virus until it is overcome and eliminated. Those who are immunocompromised may not be able to overcome the antigen and their symptoms become more serious. The antibodies formed are specific to that LIVE, REPLICATING VIRUS (antigen) and they are lifelong. Meaning if ever that pathogen (antigen) enters your body again it is immediately eliminated.
A vaccine, on the other hand, is an artificial stimulation of your immune system by using either a killed, attenuated or maybe even just a specific protein from the virus as the antigen. Because these are inert substances that are incapable of entering and replicating in your cells, your body does not perceive it as a threat. You may produce antibodies to those substances, but those antibodies are not going to be able to handle the live organism as well as naturally acquired antibodies.
Do not confuse a vaccine with plasma therapy as they are exact opposites. A vaccine is the ANTIGEN to attempt to stimulate nonexistent antibody. The plasma therapy is the ANTIBODY already formed and proven to kill the virus. Does that make sense?
You could sort of look at it like the difference between feeding your baby breast milk or formula. That which is produced naturally by the body is far superior to an artificially produced substitute.
You are fooling yourself if you think these vaccines are less risky than convalescent therapy. The vaccine does not only contain the antigen but various adjuvants, particularly in the multivalent flu (containing more than one strain of the flu) or multiple pathogens such as MMR, DPT etc.
The point is the tests we are speaking of are NOT preparing you to receive plasma therapy. They are to detect if you have been previously exposed and developed those antibodies naturally and are thus protected from the disease. In addition, if you're physically capable you could become a donor of this plasma.
