Immunity to Covid-19 could be lost in months, suggest new study

DURBAN - Assumptions of herd immunity to the Coronavirus as more people get infected may be wrong, and patients who have suffered one bout of the virus could face reinfection, according to a new study by British researchers that found that people who recover from Covid-19 tend to lose their immunity within several months.

The findings suggest that, like the common cold and flu, the virus could infect people on an annual basis.

“People are producing a reasonable antibody response to the virus, but it’s waning over a short period of time and depending on how high your peak is, that determines how long the antibodies are staying around,” said Dr Katie Doores,
