Should Zostavax be used in people who are under 50 years of age?
No, at this time, there is not enough information from the studies to determine the risks and benefits of Zostavax in people younger than 50 years of age.
All that means is that they did they clinical trials in 50+ yo people. If its safe in elderly it's safe for young folks, really. That being said if you get it younger than 50 your immunity in 10-20 years could wane, so they don't know if people would need boosters (likely at least every 10 yrs).
