The first blood sample was taken, and the level of anti-SARS-CoV-2 IgG was tested in the isolated serum. All the participants had received the 2nd dose of vaccination against COVID-19 approximately 6 months and were expected to receive the third dose of the same vaccine, the median of their IgG anti-SARS-CoV-2 level was 89.88 of IU/mL. Antibodies against severe acute respiratory syndrome coronavirus-2 (Anti-SARS-COV-2) can be detected in patients with COVID-19 in 7 to 10 days post onset of symptoms (POS). However, there is no firm evidence of the long-term persistence of these antibodies in recovered COVID-19 patients. Therefore, this study aimed to evaluate the stability of Our data supported the ability of SARS-CoV-2 mRNA vaccines to induce at least a 4 months-lasting IgG response, even outside the rules of clinical trials. The antibody decay observed at follow-up suggested to deepen the immune response characterization to identify subjects with low anti-SARS-CoV-2 immunity possibly requiring a vaccination boost. COVID-19 can be treated with monoclonal antibodies against SARS-CoV-2, but emerging new variants might show resistance towards existing therapy. Here authors show that anti-SARS-CoV-2 spike human At least a quarter of staff and a third of surviving residents were infected with SAR-CoV-2 during the first two waves of the pandemic in England. Nucleocapsid-specific antibodies often become undetectable within the first year following infection, which is likely to lead to marked underestimation of the true proportion of people with previous infection. Given that natural infection might act SARS-CoV-2 viral load, IgG antibody concentration and symptom duration in three IgG-negative patients >90 days post onset of symptoms. Ct values over time (blue circles, left y-axis), concentration of SARS-CoV-2-specific serum IgG antibodies over time (red triangles, right y-axis) and number of days of with symptoms (green bar, x-axis). COVID-19 is an infectious disease caused by the novel coronavirus SARS-CoV-2 1,2,3.Since December of 2019, COVID-19 has spread worldwide causing nearly 81 million infections and over 1.7 million The SARS-CoV-2 virus is a single-stranded RNA virus belonging to the Betacoronavirus family. It has four key structural proteins of which the nucleocapsid protein or N protein is one.
