Coronavirus reinfection more common in older people, finds study

The study discovered that merely 0.65% of subjects tested positive for the coronavirus a second time. The percentage was higher when PCR tests were used for detect the virus.

While those above the age of 65 were only protected against reinfection by 47%, younger people had 80% protection. The study has confirmed what many experts have suggested before- that while the young are largely protected, the elderly are at a higher risk of reinfection.

The researchers reiterated the importance of protecting the older population as the pandemic ensues. While there is not much research on whether the protection against second infection reduces after six months, more study is needed to find how much a person is protected against the variants of the virus.

The study was based on data collected from Denmark's testing agency. Some have called the results of the study to be more concerning than previous studies as they all confirm that the hope for immunity from the virus is far away and vaccination may be the only way out.
