    1. Dr. Tara C. Smith. (2021, January 23). A reminder: Especially among the elderly, some individuals will die shortly after receipt of the vaccine. What we need to understand is the background rate of such deaths. Are they higher then in the vaccinated population? We didn’t see that in the trials.

    1. In the peripheral nervous system (PNS) axons can be either myelinated or unmyelinated. Myelination refers to the insulation of an axon with concentric surrounding layers of lipid membrane (myelin) produced by Schwann cells. These layers are generally uniform and continuous (similar in structure to a fruit roll up), but due to imperfect nature of the process by which Schwann cells wrap the nerve axon, this wrapping process can sometimes leave behind small pockets of residual cytoplasm displaced to the periphery during the formation of the myelin sheath. These pockets, or "incisures", can subdivide the myelinated axon into irregular portions. These staggered clefts also provide communication channels between layers by connecting the outer collar of cytoplasm of the Schwann cell to the deepest layer of myelin sheath.
