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.
People are afraid of the needle that will inject into their body because they think it will hurt.
If they do not think about their feelings, they will want to go to the health centre and be vaccinated.
It could attract their attention because of the prizes from the lottery but we know that some people can think about human rights about getting vaccinated or do not want to vaccinate.
The government needs to promote their programs while educating their people but do not force them to vaccinate because they really do not want it.
