Human Albumin in Botox - is Bayer screening for liver tissue that hasn't had mRNA Covid vaccine?

Is Bayer, who I believe supplies human albumin to Abbvie/Botox, screening donors for tissue from the liver that has NOT had the mRNA Covid vaccination? Some of us are highly allergic and prefer not to have the mRNA in our system. It doesn't matter if it's a small amount of albumin or not, albium does bind spiked protein.
