Portuguese will basically suck up anything that says "freedom" in it... The idea passed around is that the vaccine allows you to freely go anywhere and with that everyone just went because staying home or staying at distance is just something the Portuguese don't really like.
They don't have an opinion on anything since 1974... Everything and anything you place in front of them they take without question.
Trust me... I'm portuguese but I've ascended from that brainwashed nation of ours.
