More awareness on vaccines needed

SOME business houses and government departments are putting up “no vaccination, no service” notices outside their offices.
At first, it was “no mask, no entry”.
I feel that more effort should be put into awareness on Coronavirus (Covid-19) vaccines.
People are still confused and hesitant to take the vaccine.
I am still not convinced about taking the vaccine.
I know a lot of people like me are asking: Does the vaccine stop you from contracting Covid-19 or is it meant for the Delta variant?
