In conclusion, this study demonstrates significant waning of VE of the third dose of the BNT162b2 vaccine against infection within a few months after administration, though significance was not reached as to a milder waning effect against severe disease, probably due to limited numbers.
This waning effect against infection should prompt policy discussion as to vaccine development and future dose allocation, particularly to low-risk populations. Additional information could assist to comprehensively estimate the effectiveness of the three-dose strategy.
