Experts blame two sub-variants of the Omicron variant, namely BA.4 and BA.5, for the rise in COVID-19 cases in Pakistan, saying that they have escape mutations that are giving them an edge. They claim that the sub-variants have been spreading to individuals who have already had a vaccination or who have already contracted COVD-19, but there is no proof that these individuals are developing a serious illness as a result of the sub-variants.
