The winter COVID-19 spike appears to be ending in Indiana. With vaccines currently being administered, could that be a light we see at the end of this tunnel?

Maybe it is, but that light is small and distant. The tunnel remains long.
The CDC recommends that vaccinated people continue to stay home as much as possible, and mask up and remain physically distanced otherwise, until enough people are vaccinated that we have herd immunity.
That made no sense to me at first. If you’re vaccinated, aren’t you immune? Can’t you go back to a normal life? But then I learned that we don’t have enough experience with the vaccines yet to know whether they keep you from catching the virus. We know for sure only that the vaccine makes you unlikely to become sick with it. After you’re vaccinated, you might still be able to carry and spread the virus! That’s why the CDC is telling us to continue to stay home as much as we can, and mask up and remain physically distanced when we can’t, until enough people are vaccinated that we have herd immunity.
I experienced this as a punch to the gut. I was dreaming about living life more freely after my vaccination. Specifically, I was looking forward to taking my wife out for dinner, and going to visit my kids in their homes!
I must continue to wait, as it will take considerable time to administer the vaccine to everyone. In Indiana, we’ve already taken care of people like healthcare workers, long-term care facility residents, police officers and firefighters, and the like. The state is now administering the vaccine by age, starting with the oldest first. People 80 and older went first, then people 70 to 79. They’re currently vaccinating people 65 to 69; people 60 to 64 are next. If this five-year grouping pattern holds, I’ll be in the second group to follow. Given the rate of vaccination, that could be a couple months yet, maybe more. I’ve heard optimistic estimates that all of Indiana could be vaccinated by midsummer, but I don’t share that optimism. Unless we’re able to dramatically ramp up the available doses and the infrastructure to deliver them, I think it will be late this year before the job is done. Perhaps then we can ease these restrictions and live a more normal life.
