Third mRNA COVID-19 Shot Boosts Antibodies Short-Term, but Study Limited by Sample Size
This study with a modest sample size found that a third dose of an mRNA COVID-19 vaccine boosted IgG and IgA antibody levels significantly for at least six months. It also revealed mild, transient increases in inflammatory markers and some changes in coagulation profile, though not clinically significant, warranting further research into long-term effects and implications for higher risk individuals.
Possible Conflicts of Interest
Funding was received from the Deanship of Scientific Research (DSR) at King Abdulaziz University, but no other conflicts were disclosed.
Identified Weaknesses
Small sample size
The sample size of 68 participants is relatively small for generalizing findings to broader populations, especially considering diverse factors such as ethnicity, geographic location, and genetics.
Limited inclusion criteria
Excluding individuals with immunodeficiencies, comorbidities, coagulation abnormalities, and inflammatory diseases limits the generalizability of the findings, as they do not consider these potentially influential factors.
Lack of long-term follow-up
The lack of long-term follow-up for IgG and IgA levels beyond six months prevents assessment of the sustained antibody response over a more extended period. Similarly, the absence of close monitoring of inflammatory cytokines and coagulation profiles within 48 hours of the booster dose restricts understanding of early dynamic changes and potential adverse events during the immediate post-vaccination period.
Rating Explanation
The study uses an acceptable methodology and presents interesting findings about the immune response to a third mRNA COVID-19 vaccine dose. However, several limitations exist, including a modest sample size and a lack of longer-term follow-up beyond six months. These factors restrict broader generalizability and sustained monitoring of antibody responses and safety profiles, making it an average study with some constraints.
