I do see the author blaming the mRNA "vaccine" (singular, deployed under EUA for SARS-CoV-2) combined with subsequent exposure to the virus. Quoting the article:
"""If you wish to blame the vaccines, then you’re left with the struggle of explaining why there are so many cases in late 2022, beginning in July, even though hardly any vaccines are administered in July, August and September. It doesn’t look like there’s a clear correlation between doses administered and sudden deaths.
As I have argued before, I believe that whatever is going wrong with the population, is a product of an interaction between the vaccine and subsequent exposures to SARS-COV-2. A simple delayed effect from the vaccine is insufficient to explain the peak in late 2021 followed by a decline in cases of people “dying suddenly”."""
