A new study conducted by researchers from the University of Oxford and Oxford University Hospitals NHS Foundation Trust found that people who contract COVID-19 are "highly unlikely" to get reinfected for at least six months.

In isolated cases of recurrence of COVID-19, illness with the SARS-COV-2 virus has raised concerns that potential remission may be short-lived and recur.

Key factors involved in the infectious period of COVID-19 were assessed by the researchers, such as the length of time a person sheds viral genetic material (RNA) of the pathogen, viral load, and isolation of the live virus.

To date, studies have found that antibodies against the new coronavirus offer varying levels of immunity from infection.

That's why the findings may not apply to people with mild COVID-19 cases, "although these results suggest those with milder cases may clear the virus faster from their body", study senior author Dr. Antonia Ho said in the release.

"We will follow this group of staff closely to see how long the protection lasts and whether the previous infection affects the severity of the infection if people become infected again", Ayre said.

Only three staff members with antibodies tested positive for Covid-19 without symptoms.

The researchers explained in their study that T cells regulate the activity of the immune system by recognising specific viruses.

"It provides a clear explanation for why SARS-CoV-2 spreads more efficiently than SARS-CoV and MERS-CoV and is so much more hard to contain", Cevik added. The new data also claims that these cells may remain in the body for a very long time, which also strikes off the possibilities of reinfection and the need for repeated vaccinations in the near future. Those three were all well and did not develop COVID-19 symptoms, they added. Covid-19: Two of the vaccine front runners have already reported promising evidence - so what now?

"That amount of memory would likely prevent the vast majority of people from getting hospitalised disease, severe disease, for many years", said Shane Crotty, a virologist at the La Jolla Institute of Immunology, with Dr Deepta Bhattacharya, an immunologist at the University of Arizona, believing that it's not an unreasonable prediction to think that these immune memory components would last for years.
