A virologist, along with an evolutionary biologist, here explain, in depth and for layperson, why that is perhaps exactly what we need to primarily be focusing on - and by targeting the immune system in a rigid way with mRNA - it's allowing more slight variants to escape immune response, that existing mRNA vaccine will still target some of the variants but at a lower efficacy (which seems to match the real world findings as well); virus attenuated vaccines would have avoided this - where if the vaccine included dead virus for the body to respond to: https://youtu.be/BNyAovuUxro https://youtu.be/BNyAovuUxro We may be growing the perfect variants to escape and may need to be getting non-mRNA vaccines for years to come, for multiple variants that become too broad difference wise from each other, to allow our innate immune system to develop a spread of variants it will target to stop the efficient development of even more variants.
