I think it will get better as long as the vaccination program keeps on going. The elderly have mostly had at least 1 shot already so that's a positive direction for sure. They just need to continue in that direction so that all residents get the vaccine as soon as possible.
It will take a considerable time to get the main populous vaccinated, during this time the hospitals will be inundated with patients which is what is happening now.
My opinion is, is will only get better once the vaccine has been administered to the vast majority of the population only then will we see a decrease in infections, not before.
As to the main businesses that have gone into administration due to no, one going to the establishments, im referring to restaurants and places where you can eat. I feel these places will never reopen unless the government gives them a grant in order to re-open.
The look and feel of the eating houses in Brazil have changed and will be different going forward.
