Virologist Professor Wendy Barclay from Imperial College London said the brand-new coronavirus is behaving in a similar fashion to seasonal coronaviruses– which are responsible for the common cold.
Prof Barclay, who is among the authors of brand-new research study which discovered that individuals’s immunity developed after a Covid-19 infection could only last a couple of months as their levels of protective antibodies decrease, told Times Radio: “This brand-new coronavirus appears to be behaving in a somewhat comparable fashion to the seasonal coronaviruses that have remained in human beings for years, if not numerous thousands of years.
” And for them we know that you do get reinfected every one or more years since your resistance, whether it’s made up of antibodies or T-cells, vanishes to such an extent that you can end up being reinfected.”
On the idea of an ‘resistance passport’– whereby individuals might set about their lives as typical after an infection– she added: “This concept of a passport for immunity– at the moment it is not a great idea because individuals can differ rather a lot in the sort of quality of the antibody reaction they make.
” We would not like people to go out and change their behaviour thinking they were protected when they are not.
” What’s more, the research study we have actually released shows that if you had to check one month, then you might need to be taking the test the next month or the month after due to the fact that your antibody levels might alter over time.”
