1 in 10.... chance of reinfection within 3 months if they survive.
we're fucked.

From my understanding, once someone gets covid, your body is much less likely to have severe symptoms if you catch it a 2nd time due to your bodys T cells. You can still get it again since the antibodies weaken after the infection is eliminated (which is the reason for seasonal vaccinations), but the T cells can eliminate the virus more efficiently if you do get it a 2nd time.

Potential for long-term immunity
Early research suggests that the antibodies in people infected with SARS-CoV-2 dropped significantly within 2 to 3 months, causing concern that humoral immunity against the virus may decline rapidly. However, it is a normal part of the immune response that antibody levels fall after an infection has resolved. For example, in seasonal coronavirus infections, antibodies start to decline at about a week after infection and typically only last for about a year. It should also be noted that memory T and B cells are formed after infection; these can be reactivated when another infection with the same virus occurs and could provide long-lasting immunity. A preliminary study that has not yet undergone peer review has shown that memory T and B cells were found in patients with mild COVID-19 symptoms who had recovered and that these cells persisted, suggesting the potential for longer-term immunity.
