It is likely that immunity from COVID-19 will exist for only six months, reports the Chronicle.info with reference to Browser.
Researchers from the University of Amsterdam regularly check 10 men for the presence of four different coronaviruses for 35 years. They are not as dangerous as COVID-19, but there is one common trend – immunity from them is valid only for six months.
The scientists noted that about once a year these men were sick with coronavirus, and within six months after recovery, the number of antibodies fell significantly.
Thus the researchers came to the conclusion that humanity may have to hurt COVID-19 annually. However, a virologist from the University of reading, Ian Jones said that it can not be argued. Still, those four coronavirus called minor diseases, and accordingly, a small number of antibodies.
However, now this study questioned the use of “health passports”, which I want to use for the safe movement across countries.
