That would make great sense for sure.  Not to mix the vaccines.  In the meanwhile Governments should also let those know who have been vaccinated that they still need to take all the precautions.  As there may be a small percentage of people where the vaccine does not work.  There may also be people who are positive for Covid 19 and don't know it.

Yeah.Here some vaccines are approved by the government to use in some provinces ,offering free(This drug is free,but you still need to pay for the human cost etc.) injections.However they still need to comply the epidemic-controlling rules like wearing face masks on public transportation,and have to be tested negative when leaving their area when new infected cases are reported there.

It doesn't mean after some injections you are golden.Even it's 99% effective - you never know who is in the 1%.And,of course,the efficiency depend on the vaccine type(mRNA vaccines seems to be better),concentration,personal situations etc.
