The mRNA vaccines developed by Pfizer and Moderna for COVID-19 contain engineered mRNA encoding the spike protein of the SARS-CoV-2 virus. This mRNA differs slightly from the viral mRNA, employing a stabilizing modification using pseudouridine. Recent studies have shown that the vaccine mRNA can persist in the body for several weeks, raising questions about potential long-term effects and protein production. Additionally, there’s uncertainty about whether the mRNA exclusively produces the native spike protein or if it generates variations. Further research is needed to fully understand the implications of these modifications and their impact on vaccine efficacy and safety.
