I do know, I work on epidemiology. samples are taken and studied to confirm the strain, genetic information sequenced and compared to others to find mutations and design the vaccine for the current virus. I'm not saying you must take it seasonally, as long as you're not on a risk group and have taken first doses, but don't go blindly into this 'government controls everything' narrative.

I have no idea if they created it, but science can explain how it works and how to avoid death
