From the time a vaccine completes phase II trials and presuming they got ideal results how long would it take from the time of completion of phase II trials to get the drug to market...most opptimistic estimate, average estimate and pessimistic estimate? Thanks.

This chart may give you a general idea of the average times required to get a drug through the clinical trials to approval process.

The particular type of drug can influence the time frames; an "orphan drug" - a drug that is being tested for a rare disease for which there is no effective treatment may get through the process a bit faster.

Vaccines often take longer due to the need to test for both the short term and long-term effectiveness of immunity and antibody levels.

Here is another (more recent) reference that looks at the drug development process:

I just added this 2nd reference - I wanted to make sure you saw this 2nd article. I may have been editing my post when you were reading my original post

Do you know how long it took the HPV vaccine or the Varicella vaccine to go through trials and get approved or where i could find this information?

This document from the FDA review of the Gardasil vaccine gives details on the trials that were done to gain approval in 2006. You can see that the first trials were started in 1997.

Here is the complete list of FDA approved vaccines. The FDA site includes information on the approval timelines including documents supporting the approval (similar to the one above)
