How effective is Zostavax to prevent shingels? Are there stats or findings?
I believe that you are referring to the Zostavax Vaccine- A live attenuated vaccine for the prevention of herpes zoster (shingles). In a clinical trial examining over 38,000 adults over 60 years of age found that incidence of herpes zoster in vaccinated seniors was reduced by 51% compared to placebo injections. Keep in mind that the rate of shingles infections was reduced from 3.3% in the placebo down to 1.6% in the vaccinated group.
So Zostavax is effective in reducing the chances of getting shingles. BUT MORE IMPORTANTLY: those that did get shingles duration of the shingles and postherpatic neuralgia (a severe nerve pain that occurs as a result of shingles) are reduced in patients that had the vaccine.
So in summary, Zostavax prevents shingles effectively AND if you did get shingles even if you had the vaccine, it would be a lot less severe because you got the vaccine.
Keep in mind that you should be screened appropriately for the vaccination by a medical professional; it is a live attenuated vaccine so you should be checked for allergies and should not recieve the vaccine if pregnant, allergic to neomycin or gelatin, or have a primary or acquired immunodeficiency.
Most common side effect is pain at the injection site.
Hope that helps!
