What this protects against
● Shingles (Herpes Zoster): Prevents the reactivation of the chickenpox virus, which causes a
painful, blistering skin rash that can last for weeks.
● Post-Herpetic Neuralgia (PHN): Helps prevent long-term, debilitating nerve pain that can persist
for months or even years after the rash has healed.
● Complications: Reduces the risk of serious shingles-related issues such as vision loss
(ophthalmic zoster), hearing problems, or secondary skin infections.
Why it’s essential
● Superior Protection: Unlike older vaccines, Shingrix is over 90% effective in preventing shingles in adults aged 50 and older.
● The “Dormant” Threat: If you have ever had chickenpox, the virus stays in your body; Shingrix acts as a powerful reminder to your immune system to keep the virus suppressed.
Doses & route
● Intramuscular Injection: Administered in the upper arm (deltoid).
● Schedule: A 2-dose series, with the second dose administered 2 to 6 months after the first.
Ideal for: Adults aged 50 and older, as well as adults 19 and older who have weakened immune systems due to disease or therapy.
