If we have SOP for process Validation in that covers continuous verification, then re-validation every 5 years is required for the product?
Continuous verification of the validated process is sufficient as long as the process remains the same without any major changes. In that case re-validation after every 5-years or periodical is not required.
If you make any major changes in the process as defined in your SOP, then yes, re-validation is required.
