This case implies a few important points which I want to highlight. First, immunity acquired through primary infection is not long-lasting and you may get infected again down the road at some point. Second, as the second case was milder than the first in this particular patient, it indicates that the immune system provides some level of protection, even if it can not prevent the infection entirely. Third, people who have recovered from Covid-19 should also be vaccinated considering the possibility of re-infection by a different strain. Fourth, people who have recovered from a primary infection should continue following precautions like wearing a mask and physical distancing.
