A small study in South Africa suggests the new variant could partially evade the Pfizer jab.
- which has not yet been peer-reviewed - found the Pfizer/BioNTech vaccine may be up to 40 times less effective against Omicron than the original Covid strain.
Scientists believe previous infection, followed by vaccination or a booster, is likely to increase the neutralisation level and will probably protect people against severe disease. There is no significant data yet on how the Moderna, Johnson & Johnson and other jabs hold up against the new variant.It was first identified in South Africa, where there is now a surge in the number of people catching Covid multiple times.
There have been more than 267 million cases and more than five million deaths around the globe since the pandemic started in 2020, according to data from Johns Hopkins University.The amount seen in this small study is in the ballpark of what scientists were expecting given the substantial mutations that Omicron has compared with original Covid that the vaccines were designed to fight.
