Just because we don’t have direct evidence, doesn’t mean we don’t know anything. We can make educated guesses and talk about what is more or less likely. For example, it’s less likely that immunity will last for 7 months, its more likely to last for a few years. For the majority of people who catch the virus and have a mild response to it, it’s unlikely they will have long term negative health consequences. Just because we don’t have concrete proof yet, doesn’t mean that all possibilities are equally likely to happen.
