As more and more people in the United States receive the COVID-19 vaccine, researchers have been able to learn more about efficacy rates in different patient populations. Unfortunately, preliminary research suggests that efficacy rates may be lower in both dialysis and transplant patients. In a small study, published April 6, 2021 on CJASN ePress, researchers found that, although study participants on hemodialysis did develop a substantial antibody response following two doses of the Pfizer-BioNTech mRNA vaccine, it was significantly lower than the response of the control group comprised of participants not on dialysis. It was also found that older patients, regardless [...]
