That's some good promotion, some people really don't like to get vaccinated because of fear what could be the effect after they get vaccinated. Rather than forcing people to get vaccinated this kind of promotion is really great first thing you will get vaccine which will protect you from the virus and after that you still have chance to win a lottery you could be a very lucky person if you managed to win on the lottery.
lol this is a bribe to make people try their luck but you as human who believes that Vaccine is risk to your life , would you still try that lottery even if you think that can be your death will be the next?
we know what our capacity and care about our life , and having this bribe just to have that vaccine luring small people than interested.
