While Omicron is known to cause COVID-19 re-infection, there is no strong evidence yet in favour of a person being affected with the vaccine-dodging strain again, Indian health experts have opined.

A recent study led by the UK's Imperial College London has shown that the risk of re-infection with the Omicron variant is 5.4 times greater than that of the Delta variant.

"This implies that the protection against re-infection by Omicron afforded by past infection may be as low as 19 per cent," said the researchers.

Rahul Pandit, Director, Critical Care, Fortis Hospitals Mumbai, said: "Omicron causes re-infection because it has an 'immune escape phenomenon' - that means that people who had acquired infection before and had antibodies, because of that or who are vaccinated and have antibodies, or have both, which is known as 'hybrid immunity'".

"However, there is no understanding if Omicron infection would happen again in these people, or not; that remains to be studied and seen," Pandit, who is also a member of National and Maharashtra's COVID-19 Taskforce, told IANS.

I haven't seen any case as such of a patient with Omicron getting re-infected with another Omicron infection; neither has been reported anywhere in the medical journals and medical literature yet," he said.

Mahashur said that in India, cases of COVID-19 re-infection have been reported, especially among those with low immunity.
