It's really strange to see what is going on. You have people who are telling others that they can mix-and-match different types of experimental injections. Different experimental injections have not completed their trials yet, while still being pushed on the world population.
These are apparently health experts, who claim without any evidence that it's perfectly safe to receive injections from different manufacturers. Not only from different manufacturers of the same technology, such as mRNA or adenovirus, but even mixing the different types of technology!
These decisions are at least being done in some places, such as Canada and the UK. They are recommending mixing and matching AstraZeneca, Pfizer and Moderna injections. 1, 2, 3
Where do they get the justification to do this? Nowhere. There there are no trials or studies that looked at the safety of this in the short or long term. There is therefore no science to back this up. But they will continue to tell you that this is science, to simply trust the science.
But there is dissent in the ranks of the experts in our society. While some ignore any potential risks in favor of merely pushing experimental injections on everybody no matter what, others are more prudent and warning of risks.
“There are no data on this whatsoever,” Cornell University vaccine expert John Moore told the Times, adding that the UK officials “seem to have abandoned science completely and are just trying to guess their way out of a mess.”
The update also stands in contrast to the guidelines established by the US Centers for Disease Control and Prevention, which explicitly states that the vaccines “are not interchangeable.”
“Either of the currently authorized mRNA COVID-19 vaccines can be used when indicated,” the CDC wrote, noting that the Advisory Committee on Immunization Practices “does not state a product preference.”
“However, these mRNA COVID-19 vaccines are not interchangeable with each other or with other COVID-19 vaccine products,” the agency said. “The safety and efficacy of a mixed-product series have not been evaluated.”
this Cornell University vaccine expert is himself saying that officials in government and other health experts have abandoned science completely and are guessing their way into making decisions. It's absurd.
