claim: the possible negative adjuvant effect of influenza vaccine to minimize the severity of covid-19
evidence_1: given the safety of flu vaccine in adult, we recommend the use of flu vaccine, at least in part, as a bystander adjuvant to minimize the severity of covid-19 disease.", "these findings are similar to what the same group have reported before in patients with influenza infection [2], [3], accordingly, we suggest a link between the quality of the immunity and recovery from covid-19, at least in part, in patients with mild symptoms.", "due to this cross reactivity between flu and sars- cov-2, we suggest that the flu-induced bystander immunity is more of beneficial effects to covid-19 than those suggested by mmr and bcg vaccines [9], [10].", 
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  "it might be possible also that individuals who received prior flu vaccination might show mild severity of covid-19 because of flu-induced bystander effect of the generated immune responses which itself might cross react against sars-cov-2.")
