Despite high vaccine coverage, Japan saw record excess deaths post-2021. COVID-19 cases surged during Omicron waves—even among the vaccinated. Is there a link between mass vaccination and rising non-COVID mortality? Are we missing long-term effects, or is the virus still the main culprit? A deeper investigation into post-vaccination mortality patterns is needed.
Seems that I have answered this question 2 years ago.
(In big simplification: pandemic prevention policies shield vulnerable populations from viruses in general, thus create a group of people who otherwise would have been already dead. When you lift restrictions you observe a spectacular flare up of infections in general as natural immunity is lower than usual in combination with elevated number of people for whom any major infection could be deadly).

The great result the world received was after discovery of vaccination against smallpox, it was really revolutionary. That is a viral disease. Virion is capable of undergoing mutation every moment, again the bacteriophases do differ. It is very difficult to invent generalised vaccination against viral disease.
There is no link here to the original article or study upon which you based the conclusion under discussion. For the USA, there was an extensive analysis. Lippi G, Sanchis-Gomar F. Mortality of Post-COVID-19 Condition: 2025 Update. COVID. 2025; 5(1):11. https://doi.org/10.3390/covid5010011
