Well, folks, first off NO vaccine has ever, or will ever be 100% effective. If you expect that, you are profoundly ignorant of how vaccines work. Vaccines rely ENTIRELY on the natural immune system of the patient. Guess what, people respond differently. It's nature, not a CIA conspiracy, or alien lizard people engaging in a covert Earth takeover attempt.
If you don't understand genetics, or protein coding and manufacture at the cellular level then you have no idea how the mRNA vaccines work, so how 'bout learning some biology before propagating nonsense?
Now, yeah Christmas is coming and I'm looking for a recommendation for a decent CD player to replace/augment my long in the tooth Sony XA20-ES. Tried the Marantz CD-6007 but it didn't beat my Sony. Not looking to spend the farm for my old ears, but the Sony won't last forever.
