  1. Will Covid vaccine mixing be adopted as health policy? They use different delivery systems carrying the genetic instruction set to produce the same spike protein, ergo ongoing studies are evaluating clinical outcomes to determine if assumption is true.
  2. AZ vaccine to be made available for everyone over 40 years of age. Fear understandable with media reporting on extremely rare blood clots but not mentioning lives saved from vaccine. Risk of harm from Covid infection causing clots is far greater.
