New research suggest coronavirus antibodies reduce within six months
Most of them caught the viruses again within three years
New research suggests a person could be re-infected with Covid-19 in six months.
The 35 year study from the University of Amsterdam involved testing 10 men regularly for four types of coronaviruses which cause the common cold.
Most of them caught the viruses again within three years with a reduction in antibody levels as soon as six months post-infection.
