Vaccinating elder patients against shingles is cost-effective in Canada and Shingrix vaccine provides better protection compared to the Zostavax vaccine, according to a study published in CMAJ (Canadian Medical Association Journal).
The study used a model to compare the effectiveness and cost-effectiveness of the recombinant subunit (RZV, Shingrix) and live attenuated zoster (LZV, Zostavax) vaccines in adults aged 50 years and older in Canada. The LZV vaccine has been available in Canada since 2008, and RZV was approved in 2017.
The number of people needed to be vaccinated to prevent one case of shingles was lower for RZV (Shingrix) than for LZV (Zostavax) for all ages. For example, in people aged 60 years, the number needed to vaccinate was 18 for RZV and 78 for LZV.
The study results are consistent with other economic evaluations in the United States and the Netherlands.
