Somewhat. However, the virus is a novel mutation, which means that even if we exposed ourselves to other similar viruses at younger age, it wouldn't help. At least that's my understanding. On evolutionary timescales, it's better to expose whole population from time to time, so that we don't lose the immune system response against these altogether.
