Some recipients of an mRNA COVID-19 vaccine, like those made by Pfizer and Moderna, have experienced a wide variety of side effects, indicating their immune system is revving into gear. However, for those who have not had such reactions, this does not mean the vaccine failed to work as intended, according to a new collaborative study, “Adverse Effects and Antibody Titers in Response to the BNT162b2 mRNA COVID-19 Vaccine in a Prospective Study of Healthcare Workers,” published Jan. 14 in Open Forum Infectious Diseases by researchers at the Uniformed Services University of the Health Sciences (USU).
