Using inactive vaccine to re-immunizing autologous hematopoietic stem cell transplant (aHCT) recipients receiving lenalidomide maintenance (LM) is safe and effective, according to a study involving 122 individuals. Participants had multiple myeloma and were vaccinated after aHCT between 2010 and 2014 at a single center. Investigators looked at vaccination safety and efficacy. Among the results:
- Three-fourths of patients were receiving LM.
- Vaccine responses differed by vaccine type; 76% responded to pertussis, 70% diphtheria, 60% tetanus, 71% haemophilus influenzae, and 58% pneumococcal.
- All patients retained polio immunity; 27% responded with increased titers.
- 3 in every 10 patients who received the hepatitis A vaccine responded; 4 in every 10 who received the hepatitis B vaccine did so.
- Response rates were similar in patients who received or did not receive LM.
- There were no vaccine related adverse effects.
