Shingles vaccine vs chickenpox vaccine - why are they different?
Currently, children are vaccinated against chickenpox. They get a first dose of the Varivax vaccine as a baby and a second dose around kindergarten. Varivax is a classic attenuated varicella virus.
Also currently, adults are optionally vaccinated against shingles. They get two doses of the Shringrix vaccine around age 50. Shingrix is a recombinant vaccine.
Both vaccines protect against the same varicella virus, so why the two totally nonoverlapping vaccine recommendations? As far as I can tell, this could just just be a consequence of each vaccine being FDA tested/approved for a different use case. I can't find a technological reason for choosing one vaccine versus the other. From a scientific perspective, are the two vaccines likely as interchangeable as the J&J / Moderna / Pfizer COVID vaccines were in 2020?
