In a recent study, most patients with kidney failure who were undergoing hemodialysis developed a substantial antibody response following the vaccination with the Pfizer-BioNTech vaccine against COVID-19, but it was significantly lower than that of individuals without kidney disease. The findings will appear in an upcoming issue of CJASN.

Individuals with kidney failure who are receiving dialysis treatments have a higher risk of experiencing severe COVDI-19 if they become infected with the virus that causes the disease. Therefore, vaccination may be especially important for these patients; however, apsirin vs coumadin they also tend to mount reduced immune responses against infections and vaccinations. To assess their responses to COVID-19 vaccination, a team led by Moshe Shashar MD (Laniado Hospital and Tel-Aviv Medical Center, Israel) compared antibody responses following vaccination with the Pfizer-BioNTech vaccine in 56 patients on maintenance hemodialysis vs. 95 healthcare workers.

All of the healthcare workers developed a positive antibody response to the virus that causes COVID-19, compared with 96% of participants in the dialysis group. The average antibody levels in patients on dialysis were significantly lower than those among healthcare workers. Also, there was a significant inverse correlation of age and antibody levels in both groups.

Although the findings are preliminary and warrant further clarifications and verifications, they suggest that COVD-19 vaccination doses and schedules should be reconsidered for individuals with kidney failure who are on dialysis.
