The covid vaccinations in wide use now (e.g. the mRNA-based shots, adenovirus-vector shots, and the Novavax protein-based shots) either cause your own cells to create or directly insert modified versions of covid spike systems into a person's circulatory system. The biodistribution study conducted by Pfizer for the Japanese government (using LNPs with a non-mRNA payload) showed that the LNPs did not all remain at the injection site but rather spread far and wide throughout the body and accumulated in particular organs. You have my sincere sympathy with regards to your mother-in-law's condition. I have heard similar and worse anecdotes in which covid vaccines (especially boosters i.e. nth shots) have been the culprits and seen some severe adverse reactions in close acquaintances.
