Let's hope that our natural (or herd) immunity keeps pace with these new variations!
Let's hope the vaccines keep pace. To get natural immunity, you have to get infected and sick. That is a high price to pay. If you are over age 60, you are likely to die. It is much better to get immunity from a vaccine. Plus, if a new variant emerges, we can change the vaccines to work with it, whereas if all you have is natural immunity, you will have to get sick again, and risk death or long term illness again.
