High efficacy, no safety signals for herpes zoster vaccine post-HSCT



In the efficacy group (n = 1,721), patients were mostly (n = 1,296) aged 50 years or older. Most patients (n = 937) received HSCT for multiple myeloma. Overall, participants were about 63% male, and 77% were of Caucasian/European ancestry.

Adverse events, solicited for the first 7 days after injections, were mostly mild and related to the local site pain and inflammation expected with an adjuvanted vaccine; HZ/su recipients also experienced more fatigue and muscle aches than did those receiving placebo. Median duration of symptoms was up to 3 days, with grade 3 events lasting up to 2 days.

Unsolicited and serious adverse events were similar between study arms, with a median safety follow-up period of 29 months. The investigators judged that no deaths were related to the vaccine, and there were no signals for increased rate of relapse or immune-mediated diseases.

The study was funded by GlaxoSmithKline; HZ/su(Shingrix) is marketed by GlaxoSmithKline. Dr. de la Serna reported being on the advisory board or receiving honoraria from multiple pharmaceutical companies.
