You can even get sick with one of the newer Omicron subvariants after getting over a different version of it. A genetic trait that harkens back to the pandemic's past, known as a delta mutation," appears to allow the BA.2.12.1 subvariant "to escape pre-existing immunity from vaccination and prior infection, especially if you were infected in the omicron wave," said Dr. Wesley Long, a pathologist at Houston Methodist in Texas.
