If 3 does are good, why not go for 4?

 For peace of mind and personal security, go for all the vaxxes you can get.  Mix and match em, something's gotta work?  Apologies to Cypress Hill, but, "Shoot 'em up and shoot 'em up and shoot 'em up and ... win!"

I'm sure there's no risk factor in multiple dosing, and maybe like with other drugs, users can figure out their personal responsive rate as the immunity wears off and it takes higher and higher doses to reach  the tolerance level to temporarily stave off the coronovirus.  Now that you've dosed multiple times, like showering before using the pool...

"Get in the globalist pit, and try to love someone!"  The rest of us are content to let the Israelis lead on the multiple dosing until they tell us how many hits we will need to save ourselves form this latest international threat...  Taking one for teh team, they are.  #GratefulForVolunteerGuineaPigs
