Understanding the time-driven shifts of vaccine effectiveness against any and severe COVID-19 before and after the surge of Omicron variants within 2.5 years of vaccination: a meta-regression

The SARS-CoV-2 pandemic necessitated the implementation of specific measures to minimize its impact on global public health. Non-pharmaceutical precautions played a crucial role in preventing the massive spread of SARS-CoV-2.[1] However, it was widely recognized that only widespread and global vaccination could effectively bring the virus under control.[2] The rapid development of various types of vaccines, supported by numerous countries and international organizations, was successfully completed within less than a year, enabling the commencement of widespread vaccination of the world's population in December 2020.
