Mixing and Matching COVID-19 Vaccines

Given the ever-changing narrative on COVID-19 vaccines, it is almost impossible for a layperson to understand exactly what is safe and what is part of the ongoing Phase 3 trials.  A recent graphic found on the website of the School of Pharmacy at the University of Waterloo adds to that confusion, particularly given that mixing and matching of vaccines was NOT part of the original vaccine program.

Here is the graphic which is supposed to allow vaccine consumers to determine whether they are fully vaccinated:

 

 

Basically, the graphic is telling laypeople that they should not be getting the AstraZeneca vaccine as their second dose unless they received it as their first dose and that either the Pfizer or Moderna vaccines are suitable as a second dose if they received the AstraZeneca vaccine as their first dose.

 

Given that these vaccines are still being rolled out and that the final phase three trials for the stand-alone products (i.e. without mixing and matching) will not end until the following dates:

 

1.) Pfizer:

 

2.) AstraZeneca:

 

3.) Moderna:

...and that the medium- and long-term side effects and efficacy of each of the vaccines on a stand-alone basis have yet to be fully understood and shared with governments, public health officials and consumers, it is concerning that governments are basically allowing Big Pharma to continue their unprecedented vaccine experiment on humanity by both extending the period of time between doses far beyond what the manufacturer recommended and allowing the mixing and matching of COVID-19 vaccines all in the name of vaccinating as much of the world as possible as quickly as possible.
