The omicron variant which spreads globally now may not be the last variant of SARS-CoV-2. With each new infection the virus gets a chance to transform. The virus will evolve more as it reaches more people. The virologists do not know about the next variants which are coming or how they will determine the course of the epidemic. The experts are not sure that the coming variants will cause mild illness or whether the existing vaccines will be effective against them. As omicron spread faster, there are more opportunities for mutations, which can lead to more variants. Omicron is more likely to re-infect previously infected individuals with Covid-19 and to infect vaccinated individuals than Delta. Longer and more permanent infections seem to be a nidus for newer variants to emerge. It happens when there is widespread infection.
