A friend tells me that they would have a new cold sore every ~3 weeks during winter months. After reading this paper: https://proceedings.med.ucla.edu/wp-content/uploads/2016/03/A151218DG-WH-edited.pdf they told the local pharmacist that they needed the chickenpox vaccine since they never had it as a child (which was a lie). Since then (about 3 years), they have only had one cold sore which was much milder than the previously typical ones.
As a side note: it seems to me like it would be worth trying this as a pre-exposure prophylactic for genital herpes if you have sex with multiple people.
