Immunity May Last ‘Very, Very Long Time’

This is exciting news.

The most robust study yet on COVID-19 immunity has found that it may last for years and perhaps decades.
The study by researchers at the La Jolla Institute of Immunology has not yet been peer reviewed, but it squares with similar findings from other labs.
Most of the 185 study participants who’d recovered from COVID-19 could still fend off the virus 8 months later—but the slow rate of declining immunity in the short term suggests protection may last a “very, very long time.”

The findings are a balm for nagging concerns that hard-won COVID-19 vaccines may have to be administered repeatedly to top up waning protection.
