  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. What should your #seconddose of #covidvaccine be if 1st was AZ? Factors include wait-time/availability, Delta variant prevalence, occupational risks, and study evidence. Answer seems to leaning to Pfizer or Moderna as 2nd dose of choice.
  3. Short-lived common side effects including fever, chills, pain, and headache after mixing AZ with Pfizer vaccine reported in @TheLancet. Immunogenicity results to be reported in June and if mixing is a viable option (likely but assumption needs evidence).
  4. I have recommended to my wife and two adult sons to opt for Moderna after receiving 1sr dose of Pfizer (unavailable this week). Mixing works and it is safe to do so. End result = protection #vaccineswork #protectyourfamilywithscience
