"A study aimed to estimate the excess mortality in Germany for the years 2020–2022, showed that in 2020, there were approximately 4,000 excess deaths, while in 2021 and 2022, there were approximately 34,000 and 66,000 excess deaths, respectively [24]. A long-term population-wide cohort study in Pescara province (Italy), analysed nearly 300,000 residents over 30 months (June 2021 to December 2023) and investigated the relationship between COVID-19 vaccination and cancer hospitalizations [25]. The study found that vaccination was associated with a 23% increased risk of cancer hospitalization after receiving one or more doses, and a 9% increased risk after receiving three or more doses. Statistically significant increases in risk were observed for breast cancer (+54%), bladder cancer (+62%), and colorectal cancer (+35%) after at least one dose. Notably, while vaccinated individuals exhibited lower all-cause mortality, this could be attributed to “healthy vaccinee effect” [26] or to the “case-counting window bias” [27], rather than a direct protective effect. A large population-based retrospective cohort study from South Korea, involving over 8.4 million adults from 2021 to 2023, assessed the cancer risks within one year after COVID-19 vaccination [28]. The study found that vaccinated individuals had a 27% higher overall risk of developing cancer compared to those unvaccinated."
