Is the Vaccine Spike the Same as the Covid Spike?

I watched this clip, SPIKE PROTEINS IN THE #JAB IS NOT THE SAME AS THE SPIKE PROTEINS IN THE VIRUS!, from an Australian senate hearing.  Senator Rennick asks some important questions about the vaccine, including a specific set of questions about an additional 70 nucleotides added to the polyA tail of the mRNA.

Senator Rennick gets the run-around, and a TGA representative gives misleading answers, as is customary with these hearings.  For example, the TGA representative states that the additional nucleotides enhance stability of the mRNA. 
Senator Rennick doesn't seem to buy it and appears to be well informed about the technology.  Does he know more?  This is what I think the Senator may have been getting at:

The poly-A tail makes the RNA molecule more stable and prevents its degradation. Additionally, the poly-A tail allows the mature messenger RNA molecule to be exported from the nucleus and translated into a protein by ribosomes in the cytoplasm.

PolyA Tail
So, the TGA was right about stability. But, he left out some important bits.
The polyA untranslated section can be manipulated to produce multiple proteins in a process called ribosomal programmed frameshifting:

Frameshifting results from two main mechanisms: genomic insertions or deletions (indels) or programmed ribosomal frameshifting. Whereas indels can disrupt normal protein function, programmed ribosomal frameshifting can result in dual-coding genes, each of which can produce multiple functional products.

On programmed ribosomal frameshifting: the alternative proteomes

Frameshifting allows them to produce multiple proteins at the same time, but TGA guy left that out.  In fact, he states that "the additional stop codons prevent any risk of translation beyond the length of the mRNA".

Thinking Outside the Frame: Impacting Genomes Capacity by Programmed Ribosomal Frameshifting is a study that actually centers on frameshifting, even naming viruses with high efficiency:

The frameshifting efficiency varies widely from only 1% of all translation events on the Barley Yellow Dwarf Virus (BYDV) genome (Barry and Miller, 2002), to up to 80% in Theiler’s Murine Encephalomyelitis Virus (TMEV) (Finch et al., 2015)

I have mentioned Encephalomyelitis virus in a previous post about crossing the blood brain barrier.  Here's a quote from that post:

I]What is an anti-mitochondrial antibody? These substances are usually made by your body if you have a condition called primary biliary cirrhosis (PBC). PBC is the most common autoimmune disease that affects the liver. Antimitochondrial antibody is found in nearly 19 in 20 people with PBC...It often strikes along with other autoimmune diseases, especially Sjögren syndrome.
And does the patent have anything related?   The patent lists peptide "Sjogren syndrome/scleroderma autoantigen 1" in its lengthy table.  From Malacards, "Sjogren syndrome is related to salivary gland disease and mikulicz disease, and has symptoms including back pain, sciatica and muscle cramp. An important gene associated with Sjogren Syndrome is IFNG-AS1 (IFNG Antisense RNA 1)"
And, what is IFNG-AS1? It is an antisense RNA with the alias "Theiler's Murine Encephalomyelitis Virus Persistence Candidate Gene 1".   This virus happens to be a picornavirus.

I made that quote in reference to a study linked to by Dr Mercola regarding vaccine side effects, where they mention the connection to Theiler's and AMA. 
So, the vaccine spike has added polyA nucleotides, which can be used in frameshifting, Theiler's Encephalomyelovirus is highly efficient at performing frameshifts, people are reporting iver inflammation from the vaccine, the inflammation has a connection with a gene in the patent, and Theiler's is mentioned as a picornavirus in the patent's ability to cross the blood brain barrier.

Are they using a virus, such as Theiler's, to cross the blood brain barrier and code multiple proteins?  Is the liver damage a side effect from using such a virus?
Is the spike protein in the vaccine the same as the covid spike? 
Is the spike a cover story for the use of the patent? 
Remember, the pandemic was originally going to be the flu, as Fauci said, but they changed it to covid for the fear factor.  The viruses were interchangeable.

Is the Vaccine Spike the Same as the Covid Spike?

No.
The vaccine "spike" is exactly what it is .
