While there's still some ways to go, scientists have now turned their attention on a subvariant that is potentially more contagious.
Dominant in several countries
The New York Times reported that scientists and medical experts are closely watching the Omicron subvariant, BA.2.According to the World Health Organisation (WHO), the BA.2 subvariant is "steadily increasing" in prevalence.
The first country to report that the BA.2 subvariant has taken over BA.1 was Denmark.
The subvariant has now reportedly become dominant in several Asian countries such as China, the Philippines, India, Bangladesh and Pakistan.
WHO said that the BA.2 subvariant now accounts for roughly one in five new Omicron cases recorded across the world.
Thankfully, scientists have revealed that there are no evidence to suggest that BA.2 is more lethal than BA.1.
Vaccines are still effective against the new subvariant as they are against other forms of Omicron.
However, they warned that the spread of BA.2 could hinder the decline of the Omicron variant.
On top of that, WHO said that the fall in Omicron around the world could turn out to be illusory, as the decline in cases is due to a drop in testing rates.
This, in turn, meant that the reported global case numbers might not reflect the true spread of the virus, WHO cautioned.
