The usual 'correlation is not causation' qualifier is very necessary here. Perhaps doubly-so because this is a meta-analysis using pooled data of over 1 million people.
It's completely possible that someone who chooses to receive an influenza vaccine is also someone who makes more cautious health decisions and is more risk-averse, reducing their COVID exposure risk. The vaccinated are also more likely to be from better health-serviced locations and probably from higher socio-economic groups.
Still, interesting association nonetheless.

A negative COVID RAT result using a validated lateral-flow device is very likely a reliable indicator of being non-infectious.
