read my original question. You answered No.
Like I said I used the word simular (if not the same) because I thought that mutations may be occurring to the spike protein and I believe that is correct according to the information below. But at the time I didn't know the answer to that question.

"SARS-COV-2 various variants share several mutations that empower them in rising population while expanding their replication wellness. Most of these mutations occur in spike gene. In order to obtain a wide knowledge over SARS-COV-2 variants of concerns and variants of interests it is imperative to notice the mutation within viral properties (12). Spike proteins enhance the entry of the virus into the host cells by attaching to the particular host receptor. Therapeutics and vaccines are a part of clinical interventions for SARS-COV-2 infection (13). Monoclonal antibodies (mABs) have shown a clinical benefit in preventing infection by acting on the SARS-COV-2 spike protein (S) (14). The S protein consists of N-terminal subunit (S1) mediating receptor binding and C-terminal subunit S2 responsible for virus cell membrane fusion. During viral entry into cells, the receptor binding domain (RBD) of S1 engages the human ACE2 (15). Fig. 2 illustrates the molecular structure of COVID-19 spike protein in details."
So yes, "(Didn't) the Pfizer and Moderna vaccines cause our bodis to create a similar protein to the spike protein on the Corona virus?"
The spike protein mutates which is one of the reasons why new mutations are more successful in entering our cells. The vaccines may be less effective against the mutations (in the spike protein) which has always been a concern. If a coronavirus can't enter a cell, we're good, because the virus needs to enter our cells in order to replicate.
