Contracting Omicron may not significantly raise vaccinated patient’s immunity against Delta: doctor

BANGKOK (The Nation/Asia News Network): It may be too soon to be excited by findings by South African scientists that patients who had been vaccinated against Covid-19 and then contracted Omicron had developed significantly stronger immunity against the Delta variant, said Dr Anan Jongkaewwatana (pic) from the National Centre for Genetic Engineering and Biotechnology.

In a Facebook post on Thursday (Dec 30), Anan said the South African study titled “Omicron infection enhances neutralising immunity against the Delta variant”, which has not been peer-reviewed, could be inconclusive due to too small a number of examples – only 13.
