Reuters file GENEVA - A World Health Organisation technical body said on Tuesday (Jan 11) that current Covid-19 vaccines may need to be reworked to ensure they are effective against Omicron and future variants of the coronavirus. The technical group, made up of independent experts, said it would consider a change in vaccination composition and stressed that shots needed to be more effective in protecting against infection. The health ministry said only 5% to 10% of the infected have sought hospitalisation, compared with 20% to 23% during the Delta-driven last wave that peaked in May. "The composition of current Covid-19 vaccines may need to be updated to ensure that Covid-19 vaccines continue to provide WHO-recommended levels of protection against infection and disease by VOCs (variants of concern), including Omicron and future variants," the technical body, tasked with making recommendations to the WHO, said in a statement. "It's truly a viral factor that accounts for reduced severity," said Dr Joseph Lewnard, a public health researcher at the University of California, Berkeley, and an author of the study, which has not yet been published in a scientific journal. "Covid-19 vaccines need to. "The situation is dynamic and evolving, therefore, the need for hospitalisation may also change rapidly," Health Secretary Rajesh Bhushan wrote in a letter to state authorities asking them to regularly review staffing levels.. The weekly Covid-19 infection growth rate fell slightly to 1.

Despite the less severe impact of Omicron, US hospitals are buckling under an influx of coronavirus cases.elicit immune responses that are broad, strong, and long-lasting in order to reduce the need for successive booster doses," it added. "A vaccination strategy based on repeated booster doses of the original vaccine composition is unlikely to be appropriate or sustainable. 22 hours ago." However, the statement stopped short of advocating an Omicron-specific vaccine at this stage, saying more research was required and urging manufacturers to share data. "Since it's more transmissible, there will just at some point be a lot of hospitalisations that inevitably occur," Dr Lewnard said. [[nid:561942]] It said that an updated vaccine could be aimed specifically at the dominant variant, which is currently Omicron in many places, or be a "multivalent vaccine" designed to bust several variants at once. [[nid:561178]] The intensive care unit utilisation rate was at 51.

Further recommendations will be issued when more data is available, it added. Some vaccine makers are already developing next-generation vaccines targeting Omicron, the highly contagious variant first detected in southern Africa and Hong Kong.7 million people. On Monday, Pfizer Chief Executive Albert Bourla said a redesigned Covid-19 vaccine that specifically targets the Omicron variant would probably be needed and his company could have one ready to launch by March. Rival Moderna Inc is also working on a vaccine candidate tailored to Omicron, but it is unlikely to be available in the next two months. A WHO official had previously said the issue of vaccine composition required "global coordination" and should not be left to manufacturers to decide alone. The researchers then followed the people who tested positive to see if they ended up in the hospital. This article was first published in .
