What i think is that eventhough we take the vaccine, we still can't stop covid but atleast it can reduce the number of severe cases including deaths.
It has been accepted world wide that the vaccine is able to curtail the dreaded disease known as Covid-19,therefore it main work is to stop the spread,kill the virus and make people live a good live.
However,it is very hard to stop the spread,thats why doctors advise people to take the vaccine.but in as much as people are scared of taking the vaccine,the risk of spreading it is high.
