Did they have an real scientists point out that we have never cured a virus? That no matter how many shots you get, you will still be vulnerable to the next Covid variant?
This is why, after millennia, people still get the common cold.
Your body has an approved and unapproved inventory of enemies to your immune system. The unapproved ones seems to be limited to about 35 enemies which generate an effective immune response during any one inventory of exposure. If you haven't been exposed lately to one of the 35, it will drop off the list and shift to the approved list due to inactivity. Something else has taken the spot based on the new threat.
mRNA technology takes over the role of your hit list of enemies by natural exposure from new exposure from conventional vaccines of weakened live virus. mRNA vaccines will overtake your natural selection listing. This could be disasterous! You would need a new mRNA vaccine every few months to fight off the many many things you become exposed to.
Please realize there have been no mRNA vaccines produced and introduced to a human population for efficacy studies. They only tell you the technology has been around for decades. That is true, but not as an approved successful vaccine for commercial use in humans.
You don’t consider yourself “cured” of the possibility to contract smallpox? Polio?
