Answer Questions About the New Shingles Vaccine Shingrix
You'll get more questions about Shingrix, the new zoster vaccine...especially now that CDC prefers it over Zostavax.
Give Shingrix starting at age 50...instead of 60. It seems to prevent shingles better than Zostavax...and immunity may last longer.
But Shingrix requires two intramuscular doses, 2 to 6 months apart...versus one subcutaneous dose with Zostavax.
