REINFECTIONS FROM OMICRON SUBVARIANT BA.2 SEEM RARE- STUDY FINDS, Making New-Wave Unlikely.

By Chandrayee Roy Choudhury, Canada: Getting infected more than once by subvariants in the Omicron family does seem possible, but appears rare, scientists in Denmark found in a recent real-world study — offering reassurance that countries won't experience another sudden surge of infections.

The early research, which was published online as a preprint on Tuesday and has not yet been peer-reviewed, involved an analysis of recent SARS-CoV-2 infections by a team from the Statens Serum Institut (SSI), a top Danish public health institute.

Many of those were the highly-contagious BA.2 subvariant, which is now dominant in that country — and on the rise elsewhere — after squeezing out other Omicron subvariants featuring different mutations, including the original lineage, as well as BA.1, BA.1.1 and BA.3.
