Yes, but keep in mind that people are not retaining immunity as long as we'd like. I can remember the exact durations involved, but there was a post on HN a few months ago indicating that some early patients had already lost immunity. The vaccines don't suffer from this limitation.
Flu immunity, including natural immunity, tends to last a very long time.
