I am a pharmacist in Canada. Shingrix has had great uptake. It is an inactivated vaccine so immunocompromised people may need not avoid it (more research needed before final conclusion). With the previous and only vaccine, Zostavax, a live vaccine, people afflicted with shingles would need to wait a year before being immunized. However, such a restriction may not need apply with Shingrix. Victims may be immunized as soon as condition crusts over. As well, Shingrix may be 97% effective vs 50% with former. And it may last 19 years vs 10.
