No it doesn't. Firstly, the paper never once asks of the relevance of the RGD motif on the SARS2 spike at positions 403-5, which we define as a mistake.And this paper completely debunks the notion that the vaccine causes cancer:

Tracking p53, we can see the RGD peptide's potential for masking the integrin:
Small molecule hormone or hormone-like ligands of integrin αVβ3: implications for cancer cell behavior - PubMed
Integrins are heterodimeric structural components of the plasma membrane whose ligands include a large number of extracellular matrix (ECM) proteins. The ligands contain Arg-Gly-Asp (RGD) sequences that enable recognition of ECM proteins by as many as eight integrins, but other distinguishing...

The very evolution of sialogenins linking integrin-disintegrin in tick saliva means that when a raccoon dog, reservoir of SARS1, swallows a SARS1-infected tick, that particular virus may not be able to do much about p53. SARS2 has RGD, and can surely interfere with DNA damage repair by occluding parts of the integrin.
