When you are infected with COVID-19 or any other virus, your body produces antibodies, a type of protein. There are primarily two types of cells, among them, the white blood cells destroy these infected cells.

There is news that worries those who are under the illusion that they will not be transmitted with COVID-19 again. This is because, according to research conducted abroad, the number of COVID-19 antibodies in the body decrease after two to three months. So, with COVID-19 gone, you also lose hope that its antibodies will last for years.

When you are infected with COVID-19 or any other virus, your body produces antibodies, a type of protein. There are primarily two types of cells, among them, the white blood cells destroy these infected cells. This is a temporary mechanism.

Antibodies to some extents last for years. However, more research is underway into how long the COVID-19 antibodies last in the body.

Current studies underway in China

The first group comprised of 37 asymptomatic participants, while the second was a group had 37 participants with mild symptoms. Both groups were found to have low levels of COVID-19 immunoglobulin (IgG) antibodies in their blood after the span of two to three months.
