Like I said - so do many vaccines. I suppose we need to all lock ourselves back in our houses for a few more years while researchers make a new vaccine for Covid-19, that does provide sterlising immunity?
This is why creating a vaccine for coronaviruses is a fool's errand. This is all very predictable. We have to look at the actual harm being done, and decide if all this is worth it.
