The verdict is still out with those who already have ME/CFS due to the compromised immune
system dysfunction/activation. This is where the treatment in the OP comes in as a result of that compromise is a cytokine storm of sorts. There will be many different vaccines used to treat covid for many differing situations. Britain for example will be using a two vaccine system to trigger immune response primarily for the general public including those with ME/CFS made from a modified cold virus which is cheaper ($4) and can be kept in a fridge unlike the vaccine from Moderna or Pfizer ($20-30) which must be kept at -80C. Apparently the the Pfizer/BioNtech (messenger RNA)vaccine will be used for front line workers, then care home residents. After that in descending order the protocol seems to be those with respiratory disease,
diabetes, immunodeficiency diseases, and then elderly, all before the general public. That could take until the end of March before the general public is addressed..
