Third dose of mRNA COVID vaccine induces strong immunity in older adults


The study results showed that two doses of an mRNA vaccine in older adults produced significantly lower levels of humoral response in terms of both binding and neutralizing antibodies as compared to younger people throughout the period of assessment. After a two-dose mRNA vaccine regimen, the predictors of weak binding antibody response included having more concomitant illnesses. Conversely, having a longer gap between the first and second doses was linked to a superior binding antibody response, confirming earlier reports. However, binding antibody levels fell faster in older adults, which is likely due to the more significant number of health conditions in this group.
