Does anybody know if previously infected persons were included in the johnson & johnson vaccine trial? is it safe for previously infected persons to take the vaccine?

Covid vaccine ?'s: The J&J vaccine is still undergoing clinical trials, but only has "effectiveness" in 66% of individuals taking it, but does have 84% prevention of serious respiratory and cardiac effects of Covid, decreasing severe effects and keeping recipients out of hospitals: if available , while waiting for Pfizer or Moderna availability, take the J&J , and you can take Pfizer/Moderna when possible also.

Please see: https://www.idsociety.org/covid-19-real-time-learning-network/vaccines/johnson--johnson-janssen-covid-19-vaccine/ to get all the details about testing. It had been recommended that mRNA vaccines may be held off for 90 days after active infection - but I was not able to find any recommendation for J& J. Please remember that J & J was tested after more aggressive COVID 19 strains cam
