How many of these shortages were caused by the unconscienable "vaccine" mandates? Biden said the pandemic is over, but the administrative/bureaucratic controls remain in place, keeping people out of jobs in the federal and state sectors. Considering we've known for 2+ years these mRNA shots don't prevent transmission or infection, it's truly absurd that this was used to deny people jobs.
