There is an incredibly stupid and and anti-science myth that is circulating around- that there is no immunity post-infection to Covid.
Here's a few papers I've read and the summary results, to save you time.
Folks, who is denying science now?

Journal of Immunology: "After reviewing Ab-mediated immunity after coronavirus and other acute viral infections, we posit that, with few exceptions, the development of protective humoral immunity of more than a year is the norm" https://www.jimmunol.org/content/early/2020/09/03/jimmunol.2000839
Immunity:
"We conclude that neutralizing antibodies are stably produced for at least 5-7 months after SARS-CoV-2 infection." https://www.cell.com/immunity/fulltext/S1074-7613(20)30445-3
"We conclude that neutralizing antibodies are stably produced for at least 5-7 months after SARS-CoV-2 infection." https://www.cell.com/immunity/fulltext/S1074-7613(20)30445-3
"Spike-specific memory B cells were more abundant at 6 months than at 1 month. SARS-CoV-2-specific CD4+ T cells and CD8+ T cells declined with a half-life of 3-5 months." https://www.biorxiv.org/content/10.1101/2020.11.15.383323v1
"We conclude that the memory B cell response to SARS-CoV-2 evolves between 1.3 and 6.2 months after infection in a manner that is consistent with antigen persistence." https://www.biorxiv.org/content/10.1101/2020.11.03.367391v1
"However, our findings raise the expectation that a significant majority of the global population is likely to have SARS-CoV-2 reactive T-cells b/c of prior exposure to flu & CMV viruses, in addition to common cold-causing coronaviruses." https://www.biorxiv.org/content/10.1101/2020.11.03.367375v1
