I suppose this depends on what the null hypothesis is? Is the null hypothesis "You have immunity after being infected" or is it "You don't have immunity after being infected". You assume it's the latter and you're saying there's not enough evidence to reject it. But you could just as well assume it is "You have immunity after being infected" and we're gathering evidence to see whether that can be rejected or not.
