Depends on the significance of the mutation. The vaccines have shown to be pretty good at protecting at the mutations we have observed so far. However, it is right to assume, that eventually a mutation comes around which evades any existing immunity. That is one the biggest reasons to reduce infection count globally. The higher the infection count, the larger the risk of a mutation that resets everything back to the beginning immunity-wise.
