Getting infected twice with two different Omicron coronavirus subvariants is possible, but rarely happens, a Danish study has found.
In Denmark, a more infectious sublineage of the Omicron coronavirus variant known as BA.2 has quickly dethroned the “original” BA.1 variant, which is the most common worldwide, but it has remained unclear whether a person could get infected by both variants, Reuters reports.
A new study, led by researchers at Denmark's top infectious disease authority, Statens Serum Institut (SSI), shows that people infected with BA.1 can get infected with BA.2 shortly afterwards, but that it is a rare occurrence.
