Should I get a vaccine if I already had COVID-19

Should I get a vaccine if I already had COVID-19 The COVID-19 antibodies in the system decrease with time after recovering from the infection, so it is necessary to get the vaccine and booster doses and get vaccinated again, to avoid COVID-19. The reinfection of COVID-19 may occur at least after 45 days of the initial infection. However, CDC also identified COVID-19 reinfection which was just 23 days apart. It occurred to an unvaccinated child who first contracted Omicron variant infection, and then a symptomatic Delta variant infection. COVID-19 reinfections may occur at least 45 days apart, though reinfection also once occurred just after 23 days of the initial infection.
