The whole concept of sterilizing immunity is largely wrong. No vaccine prevents infection in 100% of people 100% of the time.....The HPV vaccine would be the closest.Yes, I'm aware of the primary function.
What does a virus want to do and how does it do it ? Clearly a rhetorical question. The virus wants to survive and it does so by replication and transmission.
It's silly to suggest vaccines aren't intended to prevent this.
