Experts from the World Health Organization (WHO) emphasised on Wednesday that vaccines against Covid-19, including new strains that have emerged in South Africa and the United States, are still extremely effective.

Global cases of Covid-19 are steadily dropping, according to WHO data, with recorded weekly deaths at their lowest level since March 2020. The WHO's Director-General Tedros Adhanom Ghebreyesus emphasised at a press briefing on Wednesday that these patterns don't tell the whole story. "We're seeing a spike in reported cases in the Americas and Africa, thanks to Omicron sub-variants. Two new Omicron sub-variants, BA.4 and BA.5, have been identified as the cause of a spike in cases in South Africa by the South African experts who discovered Omicron late last year "he stated. "It's too soon to say if these new Omicron sub-variants can cause more severe disease than existing Omicron sub-variants," he noted, "but early data suggests vaccination is still protective against severe disease and mortality."
BA.4 and BA.5 have been found in a number of nations, according to Maria van Kerkhove of the WHO's Health Emergencies Program. The severity of the two novel variations is still being assessed by the WHO.

"Vaccines are still highly effective at preventing serious disease and death." She also demanded that COVID-19 be monitored and tested in order for the WHO to offer the public with the most accurate information and guidance possible.
