I got covid-19 (omicron) after two vaccines doses (AstraZeneca, that is not as effective as the mRNA versions). I took paracetamol/acetaminophen but I got a strong burn sensation in the throat for two days until I notice it was caused by acid reflux so I took anti acid. I still got a lot of phlegm and cough for a few more days. I guess unless there is a preregistered double blind randomized controlled trial it's difficult to separate the signal from the noise.
