A new study suggests that post-infection immunity COVID-19 remains strong after 8 months.
What is happening?
In a new study, the researchers said that there is a robust immune response to COVID-19 for eight months after infection.
- The study – published in the journal Science – said that about 90% of the patients studied had stable immunity.
The study reviewed blood samples from 200 patients. The samples showed that the immunity system – not just the antibodies – recognized COVID-19 and responded to the virus.
- The immune system appears to recognize the COVID-19 virus and generate a counterattack against it.
Why it matters:
The Washington Post made it very clear: “There have been isolated reports of people having a second case of COVID-19, the disease caused by the virus, but which seems to be rare, and the new study reinforces the case that immunity generally persists. “
COVID-19 immunity
A new study by the Centers for Disease Control and Prevention found that people who recovered from COVID-19 may have less than 90 days of immunity, according to Deseret News.
The new study looked at 156 health professionals in the U.S. who tested positive for COVID-19 for the study, giving them an antibody test one month after the systems were developed.
- 94% of participants showed some kind of decline in antibodies at the time of the second test.
- 28% experienced a significant decline.
