Final 2 paragraphs also very relevant:
"Confounding by age may be present in the 60 years or older age group, which may explain the slight
elevated risk for cardiac-related deaths following vaccination. This may also explain the increased risk
for the entire vaccination analysis group for cardiac-related deaths since this group comprises the vast
majority of deaths. Removing those aged 60 years or older yielded non-significant results for cardiac-
related deaths following vaccination (RI = 1.15, 95% CI = 0.99 - 1.34), mRNA vaccination (RI = 1.17, 95%
CI = 1.00 - 1.37), and males with mRNA vaccination (RI = 1.09, 95% CI = 0.89 - 1.34).
Lastly, this analysis was conducted during the first months the vaccines were available. Both COVID-19
mortality due to infection or risk of mortality associated with vaccination have likely changed over time.
In the fall of 2022, most people have either been vaccinated or have natural immunity to COVID-19.
Many have had multiple vaccine doses, multiple infections or both. Research to assess the current risks
and benefits of the COVID-19 vaccine to help update vaccine recommendations should be studied in this context"
