COVID-19 reinfections likely as antibody counts fall: WHO

The World Health Organization (WHO) confirmed that new data suggest individuals who were once infected with COVID-19 can be susceptible to secondary infections as antibodies die off. “We have seen the number of people infected continue to grow, but we’re also seeing data emerge that protection may not be lifelong, and therefore we may see reinfections begin to occur,” Mike Ryan, executive director of the WHO’s health emergencies program, said per CNBC. “So the question is: What are the levels of protection in society?” Researchers at the WHO are now working to determine how long antibodies in response to COVID-19 last in the human system.
