mRNA vaccines work by providing the genetic code for our cells to produce viral proteins. Once the proteins, which don’t cause disease, are produced, the body launches an immune response against the virus, enabling the person to develop immunity.

Question 1: the proteins are produced by cells that presumably go on to replicate, with the mRNA changes incorporated in their replications. Then the replicated cells produce more viral proteins, which our immune system will presumably attack. What happens when the number of modified cells is producing enough viral protein to overwhelm the immune system?

Question 2: Why does the body launch an immune response to something that is produced by our cells? Why does it not recognise that the viral proteins are produced internally, and so should not be attacked?

Question 3: If the immune system is attacking viral protein, what will it do when it sees, not just the “spike”, but the whole virus?

Question 4: What will happen when someone who has had the vaccine, and so is producing viral protein, is trying to conceive a child with someone who hasn’t had the vaccine, so may recognise the other person’s sex cells as “foreign” and attack them?

Is there a doctor in the house? I'd really like to understand the way things work
