Thank you for the information! Good news for pro-lifers as well since the Novavax vaccine did NOT use fetal stem cells at any stage of research and development or production; just like Moderna and Pfizer.

Some of the after-the-fact (in other words, they already had produced the vaccine, bottled it, and readied it for shipping) confirmatory testing did use fetal stem cells, I'm not so sure on that. It's extremely difficult to follow this stuff, and many companies hide it the best them can, but according to the
paper linked to for NovaVax here, at least six of the authors involved in the fetal line testing, are employees of NovaVax. And I can't see these companies allowing for much 'independent' testing of their products by their employees.
I can’t speak to the specifics of NovaVax’s testing as I’m passing on second-hand reported information, but what I can say is that the FDA does require fully independent testing be performed to confirm the in-house testing of the manufacturers.
In other words, you have to test your own product to make sure it works as expected, but you then have to pay someone else and hand them your product so they can also test it. How they test it is up to them. You have zero control. At the end, you submit both your results and the independent test results to the FDA, who reviews everything ensuring that everyone is in agreement that your product does what it’s supposed to do.
