Short-term immunity to COVID-19

Chinese scientists claim that immunity to COVID-19 is temporary and lasts no more than 2-3 months. And in 40% of asymptomatic patients, after a few months, it ceases to manifest itself at all.


Scientists from Chongqing Medical University conducted a preliminary study and found that already 8 weeks after the disease, the level of antibodies to coronavirus is significantly reduced. It is published in the journal Nature Medicine.

During the study, 74 patients with coronavirus were examined. 50% of them were asymptomatic, and the remaining 50% had signs of COVID-19. Already after 8 weeks, the antibody content decreased in 81% of asymptomatic and in 62% of patients with symptoms.

In addition, in 40% of asymptomatic carriers, antibodies ceased to appear at all in the eighth week. And among patients with symptoms, only 12.9% of people had this problem.

If the results of the study are correct, this means that the coronavirus can be infected again – this is only a matter of time, because immunity lasts only for 2-3 months.

This is not the first such study. Recently, experts from the University of Amsterdam said that immunity to COVID-19 can last up to 6 months.
