My big question is exactly why this vaccine is developed with a MRNA genetic code to create an antibody response from our own natural immune system. I wish I understood the science more and why so many people have breakthrough Covid infection even after vaccination. But since I don't know science then I must trust the scientists to survive this endemic disease with unknown origins that now seems to need regular booster shots!
