The immune system is what defends our body against the virus.

The immune system was of paramount importance during the covid-19 pandemic.

It is no wonder. This complex network of cells, tissues and organs is the main weapon our body has to defend itself against SARS-CoV-2, the new coronavirus that causes this disease.

Like any other part of the body, the immune system ages over the years, making us more vulnerable to infections, cancer and all kinds of diseases.

This is one of the reasons why – in addition to the prevalence of pre-existing conditions – people over 65 are more at risk of getting covariectomy and developing a more virulent form of the disease.
