There are some things which can be known only through the passage of time. One of these is the permanence of immunity to a disease. For some, with smallpox as an example, immunity once achieved is very long-lasting. For others, not.
There are indications that immunity to the SARS-CoV-2 virus is of relatively short duration. More will be known with time. The actual time period may alter the use of a vaccine, should one be developed and found to be safe and efficacious.
Stay tuned ...
