I SAY PLEASE SAY NO. 
This liberal government wants to again use your tax dollars to force you into lifelong vaccine passports. 
So after booster 6 you are now faced with the decision of taking booster 7 in 2 weeks or lose your passport and go into the non passport lifestyle of not being allowed to shop except for food and medicine. 

Remember, we went from 2 weeks to flatten the curve to 20 months and now only allow the vaxxed into gyms, movie theatres, inside restaurants etc until they ban more. 
please think about this. There is no turning back once you allow them to force this into you.
