People can get infected twice with the Omicron variant of COVID-19 – but only in rare cases, according to a new Danish study.
Researchers at the Statens Serum Institut, Denmark’s top infectious-disease authority, found that a small number of people infected with Omicron’s BA.1 subvariant can contract its BA.2 strain shortly afterward.
“We provide evidence that Omicron BA.2 reinfections are rare but can occur relatively shortly after a BA.1 infection,” the authors said.
