Clinical Symptoms among Different Types of SARS-COV-2 Vaccine in Nineveh Governorate

Abstract

Different mechanisms are used by the COVID-19 vaccines to elicit immunity. This study
compares the titers of particular antibodies, clinical symptoms, and recurrence of COVID-19
infection in individuals who received the Pfizer-BioNTech COVID-19 vaccination, the
Sinopharm vaccine, and the AstraZeneca vaccine after receiving the vaccine. In recipients of
the three different vaccination types, the IgG rate was similar, however, the IgM rate was higher
in recipients of the Pfizer and Sinopharm vaccines when compared to control samples. The
three types of immunizations caused some persons who had received vaccinations to have
various symptoms, the most serious of which was fever. The IgG rate likewise reached its peak
in people who had a fever and had received the Pfizer vaccine, in people who had a sore throat
and had received the Sinopharm vaccine, and in people who had joint discomfort and had
received the AstraZeneca vaccine.
