Dear Right,
Our immune systems are amazing! They have so many parts and do so many things! Just having antibodies, even lots of antibodies is not the same as being immune. Covid is still pandemic. The focus is still on widespread cohesive immunity. The more we do to slow the spread, the greater chance there is that the virus will be come endemic, or seasonal. At that point, you will be correct in stating that your safeguards is up to your own judgement.
