It might be too early to be delighted by South African scientists’ finding that patients who were vaccinated against Covid-19 and then contracted Omicron developed significantly stronger immunity to the Delta variant, according to Dr Anan Jongkaewwatana (pic) of the National Centre for Genetic Engineering and Biotechnology.


Contracting Omicron Variant May Not Improve Immunity Towards Delta Variant 

It might be too early to be delighted by South African scientists’ finding that patients who were vaccinated against Covid-19 and then contracted Omicron developed significantly stronger immunity to the Delta variant, according to Dr Anan Jongkaewwatana (pic) of the National Centre for Genetic Engineering and Biotechnology.

Anan said in a Facebook post on Thursday (Dec 30) that the South African study, titled “Omicron infection enhances neutralising immunity against the Delta variant," may be inconclusive due to the study’s small sample size – only 13.

I have reviewed another study by Hong Kong scientists among only two candidates who contracted Omicron after they had been vaccinated with two doses of mRNA vaccines,” he said.

The result showed that the first candidate had improved neutralising immunity against Delta 9.58 times higher than unvaccinated persons. However, in the second candidate, the Delta immunity went up only 1.42 times,” Anan said.

This indicates that after contracting Omicron, a patient’s immunity against Delta is still not significantly higher than that of unvaccinated people,” he pointed out.

The South African study is indeed interesting, but we still need more extensive studies before we can conclude that contracting Omicron could serve as nature’s immunity boost against other variants,” Anan added.
