Claim that flu shot causes false positive results on COVID-19 tests is unsupported and misleading

The 2012 study cited in this claim only tested for coronaviruses that cause the common cold, but not COVID-19, which was not discovered until 2019. Furthermore, only one of 69 individuals who had received the flu shot tested positive for coronavirus—a frequency that precludes drawing a causal association between the flu shot and coronavirus detection.
