National surveillance in England showed low risk of reinfection with Covid-19 – “There were 15,893 possible reinfections with SARS-CoV-2 identified up to 30 May 2021 in England throughout the pandemic, out of nearly 4 million people with confirmed infections. This is equivalent to around 0.4% cases becoming reinfected”.

“Immune escape” in #DeltaVariant.
