In particular, re-infection may make the idea of herd immunity – that is, a sufficiently high proportion of people eventually become immune to Covid-19 – unrealistic.
“Re-infections mean that the immune response in some people is not sufficient to protect them from infection or disease,” said Akiko Iwasaki, professor of immune biology, molecular, cellular, and developmental biology at Yale University.“.
“Re-infection from -CoV-2 (the virus that causes Covid-19) means that immunity acquired through natural infection is not ideal,” he added.
The researchers who documented the case of a Nevada patient provided a number of possible explanations for how he became ill twice, perhaps he was exposed to a very high dose of the virus the second time, which led to a more severe reaction, or it may be a more virulent strain of the virus..
