So far people have suffered enough financially that lottery like this will slightly stimulate people to hope for a prize even if they have to be vaccinated. This is a good step from the government to make its citizen willing to receive the vaccine so that without realizing it the public has helped the government to complete the vaccine and also break the chain of transmission of covid.
Maybe it will be better to give that money to all people who are already vaccinated because I think that money is really worth it for those who do not have an income.
I would probably think that this would also be a lucrative option for all those who are willing to receive the vaccine especially for those who do not have a steady income. I believe this move will increase the number of lower middle class citizen for receive the vaccine, but not for the elite. However, this step deserves appreciation.
