Some good news amid the doom and gloom: People have Longer immunity to Coronavirus infection after recovering from it.

After someone has recovered from a Coronavirus infection, the body remembers how to fight the virus in future. This is called immunity and it is not known how long this immunity will last.

If the immunity is not long lasting, people can get coronavirus infection again during the second and even third wave.

The body’s immunity is made up of two types of cells: B cells and T cells. T cells and B cells are central to the human immune system.

B cells produce antibodies and previously in various studies , they were found to decline rapidly give rise to fear that people would get Coronavirus infection again and again.

Now a study has reported that T cell immunity can last more than 6 months in patients who have recovered from an infection.

This news is also good from a vaccine point of view. It gives us hope that sooner or later an effective vaccine would become available.
