We all know a few of those lucky people who, somehow, have managed to avoid ever catching COVID?

However, the number of people who have actually been infected with SARS-CoV-2, the virus that causes COVID-19, is thought to be higher.

The reason why some people appear immune to COVID is one question that has persisted throughout the pandemic.

Yet there are people who have experienced high levels of exposure, such as hospital workers or family members of people who have had COVID, who have somehow managed to avoid testing positive.

Once a person does become infected, researchers have identified that differences in the immune response to SARS-CoV-2 play a role in determining the severity of symptoms.

It is possible that a quick and robust immune response could prevent the virus from replicating to any great degree in the first instance.

The efficacy of our immune response to infection is largely defined by our age and our genetics.

Just as genetics could be one determining factor of disease severity, our genetic makeup may also hold the key to resistance to SARS-CoV-2 infection.

We discovered some really interesting genetic mutations, including several involved with the body’s immune response to infection, that could explain why.

A mutation we identified in a gene involved with sensing the presence of a virus has previously been shown to confer resistance to HIV infection.

This is where our immune system may recognise SARS-CoV-2 as being similar to a recent invading virus and launch an immune response

If you’ve managed to avoid COVID to date, maybe you do have natural immunity to SARS-CoV-2 infection, or perhaps you’ve just been lucky
