People Infected With Omicron Unlikely To Catch BA.2 Shortly Afterward

BA.2 is a spin-off from the Omicron variant, known as BA.1, but appears to be 1.5 times more infectious than its predecessor and is on course to become dominant in the UK. However, scientists have said there is no indication that BA.2 is more deadly or better at evading immunity than Omicron…

Many of these reinfections were observed in people under the age of 30, the researchers said.

Reinfections were characterised by overall mild symptoms comparable to the initial infection and did not lead to hospitalisation or death, according to the study.

“It is, however, striking that mainly children and adolescents become reinfected, since children to a higher degree than adults develop a sustained cross-reactive immunity,” the authors note.

“This may be explained by the very high incidences among children in the chosen study period, whereas adults and elderly had lower incidences.”
