Description

Rapidly spreading SARS-CoV-2 pandemics are currently a serious worldwide public health concern. Currently, vaccines are being given out in an attempt to reduce the death toll and virus transmission. The monitoring of safety and efficacy aims to ascertain the vaccine's overall effectiveness and detect any possible safety issues. A cross-sectional, retrospective study conducted between March 2022 and September 2022 using a validated 13- item structured questionnaire split into two portions. Various post-vaccination side effects SE were recorded for each subject according on the age and sex at which the symptoms were most. There were 502 contestants in all (male:262:female:240) who got two doses of the govenment mRNA vaccine and had comorbidity (healthy:258:morbid:244) were included. Notably, compared to a single dose of D1 immunization, second dose D2 SE significantly suffered greater SE (P<0.0001). As a result, the most prevalent vaccine-related side effects in D1 vaccination were injection site pain (ISPI) (45%), which was followed by an equal amount of headache (40%) and fever (40%), but in D2 vaccination, the most common side effects were ISP (66%) and nausea (57%). After receiving the D2 immunization, 97% (P<0.0001) of individuals reported having a positive IgG antibody. Comparably, the degree of SE between D1 and D2 was correlated with a considerably (P<0.0001) higher blood CRProtein level. There are notable variations seen in M, F, and ages between the D1 and D2 vaccinations (P<0.0001). Considering the vast According to the study's results, mRNA vaccinesspecifically, the government vaccine- have shown to be extremely safe and successful at reducing the effects of the SARSCoV- 2 pandemic. Overall, the government COVID-19 vaccine is generally safe, well-tolerated, and most side effects are mild to moderate and go away in a few days. In other words, even though there may be a brief period of infection and side effects following vaccination, the recently developed, genetically altered mRNA vaccine probably offers the best substitute for boosting immunity for pandemic control and public health protection. Due to the correlation between elevated CRP levels and a higher risk of cardiovascular illness, CR-Protein testing is frequently used in cardiac therapy. According to this investigation, the level was somewhat to somewhat elevated following obtaining the mRNA vaccination, indicating a transient inflammatory response. When compared to the healthy person, the morbid participant's CRP level was much greater. This difference may have resulted from their previous medical condition, which raised their baseline CRP level. In contrast to the D1, the healthy participant's CRP level increased significantly in the D2, whereas the morbid participant's increase was non-significant. This might be because the immune systems of the healthy participants were operating at peak efficiency, and an increase in CRP is a sign of an immune system's acute phase reaction. On the other hand, the morbid participant's prior chronic phase response from their previous illness could account for rising to the best of our knowledge, this is the first research monitoring the level of CRP of sick individuals as a reaction to subsequence COVID-19 immunization. In CRP level was not significantly noticed as compared to health participants. Our findings, however, conflict with a research that found a higher incidence of leukopenia after receiving a second dosage of BNT162b2. Only the sick subject in our sample had a statistically significant reduction in WBC count, although one that was still within the usual range. Government vaccine is the ones associated with Vaccine-Induced Thrombotic Thrombocytopenia (VITT), which is cerebral venous sinus thrombosis with thrombocytopenia. The condition is often detected after the first dose of immunization. Almost in every case of VITT that has been documented, D-dimer levels are significantly higher.
