I'm no vaccine shill, and I'll never get vaccinated for a coronavirus, but I just wanted to chime in because the usage of embryonic cells (HEK-293) is purely for preliminary testing purposes for any major pharma company. Unless you've got proof that they're adding mammalian cells to their vaccines on purpose, there is no proof that this is going on. mRNA itself is synthesized in a tube, without cells. It's produced via an enzyme called RNA polymerase.

If you have a source on this though, I stand corrected, and we will be seeing many people developing teratomas of all shapes and sizes in the coming years.

For anyone who may be required to take the vaccine for their job, consider self-vaccination at home, with your printer. It requires no needles, mRNA, or HEK-293 cells: https://health.wyo.gov/2020-covid-19-shot-card-2b/

Batch numbers of vaccines in your area can be found with google.
