Background

Documentation of influenza vaccination, including the specific product received, is critical to estimate annual vaccine effectiveness (VE).

The proportion of records captured by MCIR increased from a low of 67% in 2013-2014 to a high of 89% in 2018-2019, largely driven by increased capture of vaccination among adults.

Conclusions
