The Spokesperson told Xinhua that BA.4 and BA.5 continued to be the most dominant sub-variants in South Africa but they were less severe due to higher levels of immunity. The department called on the people not to panic.

While existing vaccination can still reduce the risk of severe Covid disease, the variants can evade many of the neutralising antibodies that are the immune system's front line of defence.
