Can an individual be contaminated with Omicron twice? This is what consultants need to say

New Delhi: Whereas Omicron is thought to trigger Covid re-infection, there isn’t any robust proof but within the favour of an individual being affected with the vaccine dodging pressure once more, mentioned Indian well being consultants right here on Monday.

Nevertheless, in addition they didn’t rule out such a risk.

A person’s immunity which has been primed by prior an infection or vaccination has the reminiscence of the guardian virus.

However as a result of Omicron is a deviant, that means it has deviated rather a lot from its guardian Covid pressure, it has many dissimilarities.

In consequence, “our immune system fails to recognise the virus as the unique virus and therefore the prospect of re-infection. Together with the above the waning immunity of naturally contaminated people with passage of time may also contribute to the re-infection”, Dr. Dipu T.S, Affiliate Professor, Division of Infectious Illnesses, Amrita Hospital, Kochi, advised IANS.

Though re-infections are there, “there may be not but robust proof in favour” of Omicron recurring in a person, added Dr. Ashok Mahashur, Guide Chest Doctor at P.D Hinduja Hospital & MRC, Mahim, Mumbai.

A current examine led by the UK’s Imperial School London has confirmed that the chance of re-infection with the Omicron variant is 5.4 instances larger than that of the Delta variant.

“This suggests that the safety towards re-infection by Omicron afforded by previous an infection could also be as little as 19 per cent,” mentioned the researchers.

Dr. Rahul Pandit Director, Important Care, Fortis Hospitals Mumbai, mentioned: “Omicron causes re-infection as a result of it has an ‘immune escape phenomenon’ – that implies that individuals who had acquired an infection earlier than and had antibodies, due to that or who’re vaccinated and have antibodies, or have each, which is called ‘hybrid immunity’”.

Omicron has greater than 30 mutations on its spike proteins, serving to it to flee immunity. That’s the reason it’s infecting individuals who have been beforehand having antibodies as effectively.

“Nevertheless, there isn’t any understanding if Omicron an infection would occur once more in these folks, or not; that is still to be studied and seen,” Pandit, who can also be a member of Nationwide and Maharashtra’s Covid-19 Taskforce, advised IANS.

“We shouldn’t be speculating if such re-infection would occur or not. I haven’t seen any case as such of a affected person with Omicron getting re-infected with one other Omicron an infection, neither has been reported anyplace within the medical journals and medical literature but,” he mentioned.

However, some western consultants have argued that Omicron can reoccur.

“Sure, you may get Omicron twice,” Stanley Weiss, Professor on the Rutgers New Jersey Medical Faculty was quoted as saying in a media report.

Whereas, “the info concerning Omicron particularly is simply popping out, however there’s no cause to assume that Omicron on this regard is any completely different than the earlier variants”, added William Schaffner, Professor on the Vanderbilt College Faculty of Drugs, within the report.

Nevertheless, Kingston Mills, Professor of Experimental Immunology at Trinity School Dublin mentioned it was “too early” for folks contaminated with the virus after which caught once more. The image could also be clear in six months’ time, Mills was quoted as saying to Monetary Occasions.

Mahashur mentioned that in India, circumstances of Covid re-infection have been reported and particularly amongst these with low immunity.

“One of the best ways to forestall that is by following a Covid applicable behaviour. As a result of there isn’t any approach to know whether or not the virus is there or not. The virus could also be there, however the affected person could also be asymptomatic, so one of the simplest ways to forestall it’s by taking vaccines, sporting masks, washing arms correctly, and avoiding crowded locations,” Mahashur advised IANS.
