A team of scientists from different countries has studied the issue of immunity in patients for coronavirus, the journal bioRxiv writes.
The scientific study notes that in patients recovering from coronavirus, it gradually decreases after the first six months, although it remains stable until the 15th month.
Researchers in Sweden, Italy, Germany, Switzerland, and China collected 188 blood samples from 136 patients who had severe or mild forms of the virus.
The highest rate of antibodies was observed 15 to 28 days after coronavirus infection.
