Immunity Can Last Eight Months from Covid-19

Jakarta – Australian researchers reveal that people who have been infected with the Covid-19 virus have immune memories to protect themselves from reinfection for at least eight months. This research is the strongest evidence of how a vaccine is likely to fight the Covid-19 virus and will work for a long time.

Previously, many studies had shown that the first wave of antibodies to the Corona virus was reduced after the first few months raising concerns that people could lose immunity quickly. However, the new findings dispel that concern.

This research is the result of a collaboration led by Professor Menno van Zelm from the Department of Immunology and Pathology at Monash University. He collaborates with the Alfred Research Alliance between Monash University, the Alfred Hospital and the Burnet Institute, Australia.

Quoting from MedicalxpressThe findings reveal that specific cells in the immune system called memory B cells “remember” infection by the virus. Re-exposure to the virus triggers a protective immune response through the rapid production of protective antibodies.

The researchers took 25 Covid-19 patients and took 36 of their blood samples 4 days to 242 days after infection. Like other studies looking at antibody responses, the researchers found that antibodies to the virus began to decline 20 days after infection.

However, the most important thing of all patients is that they retain memory of B cells that recognize one of the two components of the Covid-19 virus, namely the spike protein and nucleocapsid. Memory against the B cell virus will continue to exist steadily for up to eight months after infection.

According to Professor Menno van Zelm, these results provide hope for the efficacy of any vaccine against the virus. It also explains why there are only a few examples of genuine reinfection in the millions of people who test positive for the virus globally.

“These results are important because they definitively show that patients infected with the Covid-19 virus are in fact maintaining immunity against the virus and the disease,” Zelm said.
