Paper Summary

Paperzilla title
More COVID Jabs Didn't Stop Flu-Like Illnesses in Healthcare Workers

In a study of healthcare workers, increasing the number of COVID-19 vaccinations did not lead to fewer influenza-like illnesses (ILI) or days off work. Smoking and male sex were linked to more ILI, while the seasonal flu vaccine was linked to a lower risk.

Explain Like I'm Five

More COVID vaccines didn't mean fewer flu-like illnesses or sick days for healthcare workers during a time when both COVID and the flu were spreading a lot.

Possible Conflicts of Interest

Tala Ballouz disclosed receiving grant/research support from Moderna.

Identified Limitations

Study Population Limited to Healthcare Workers
This limits the generalizability of findings to the general population or other specific populations. Healthcare workers may have different exposure risks, vaccination patterns, and access to healthcare compared to other groups.
ILI Assessment Based on Self-Reported Symptoms
ILI is based on self-reported symptoms, which can be subjective and prone to recall bias.

Rating Explanation

This is an observational study with a specific focus on healthcare workers, which limits its generalizability. While it employs appropriate statistical methods, the reliance on self-reported symptoms introduces a potential source of bias. One author disclosed financial ties to Moderna.
