Also to clarify, if you did get it and were asymptomatic, you may have developed some immunity. The problem is no one knows for sure if you would be immune or how immune you actually are to maybe a large dose of the virus or a slightly different strand. The point being, even if you do gain some immunity from catching the virus and recovering (asymptomatic or not), you should still proceed with caution and act as if you are not immune at all. But based on other virus' and what Dr. Fauci has been saying, there is some truth to potentially gaining an immunity to the virus after recovery.
