As many people suspected, there is now a study from the Cleveland Clinic [SEE HERE] showing there is no need to vaccinate anyone who previously recovered from the COVID-19 virus.  The vaccination provides no additional benefit.

CLEVELAND CLINIC – ♦ Conclusions – Individuals who have had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination, and vaccines can be safely prioritized to those who have not been infected before.

♦ Summary – Cumulative incidence of COVID-19 was examined among 52238 employees in an American healthcare system. COVID-19 did not occur in anyone over the five months of the study among 2579 individuals previously infected with COVID-19, including 1359 who did not take the vaccine. (details)
