There needs to be a mandate because the vax teaches your body how to fight covid right away (rapid immune response) instead of learning how to kill it while it multiplies and gives you a worse infection, and a higher chance of spreading it around.
mRNA is just half a strand of DNA that your cells can make into a harmless thing that vaguely looks like covid, instead of injecting dead virus (which is just as safe). It's still held to the same safety standards as any FDA approved vaccine.
