A new study suggests that post-infection COVID-19 immunity remains strong after 8 months.
What’s going on?
In a new study, researchers said there’s a robust immune response to COVID-19 for eight months after infection.
- The study — published in the journal Science — said about 90% of the patients studied showed stable immunity.
The study reviewed blood samples from 200 patients. The samples showed that the immunity system — not just 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 laid it out quite clearly: “There have been isolated reports of people having a second case of COVID-19, the disease caused by the virus, but that appears to be rare, and the new study bolsters the case that immunity usually persists.”
Immunity from COVID-19
A new study from 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 the Deseret News.
The new study looked at 156 health care workers in the U.S. who tested positive for COVID-19 for the study, giving them an antibody test one month after developing systems.
- 94% of participants showed some sort of decline in antibodies by the time of the second test.
- 28% experienced a significant decline.
