An expert has warned that the new mutated coronavirus dubbed “Covid 22” may be more deadly than the delta that dominates the world.
Professor Sai Reddy, an immunologist, said we must prepare for a new variable emerging in 2022 that could pose a significant risk, as the coronavirus will continue to evolve.Zurich-based Reddy warned that it is “inevitable” that already existing variables such as delta (India), beta (South Africa) and gamma (Brazil) combine to make the strain more capable, and Covid 22 could be worse than what we are seeing now.
“If such a variant emerges, we need to identify it as soon as possible, and vaccine manufacturers must adapt the vaccine quickly. The emergence of this new variant is a big risk. We have to prepare for it,” Reddy added.
Speaking to the German newspaper Blick, Reddy explained that Delta, which he called “Covid 21”, is the most infectious species of all, but he did not get “runaway mutations”, which are genetic traits that help viruses evade the immune system. The escape mutations, which appear in some mutant such as beta, mean that vaccines become less effective and may need to be modified in order to protect the population.
Prof Reddy said a combination of these factors – either more lethal, transmissible or immune evasion – will be a problem in the near future, the next phase of the epidemic when beta or gamma become more infectious or delta escape mutations develop. This will be a big problem for next year.
It is expected that new variants of corona will appear in the future because it is a natural part of the evolution of viruses, and it is impossible to predict whether they will become more dangerous, but with many of them already appearing in less than two years, this does not bode well.
In a paper published on July 30, researchers described the possibility that Covid could become more deadly as “likely” to “a realistic possibility”, due to the continued spread of the virus at such a high level globally, and the document stressed the importance of continuing supportive vaccination campaigns. The benefit of the booster doses is to make sure that people get the maximum protection possible – as immunity wanes over time – and vaccines are likely to be modified against the new variants.
