Pfizer booster vaccine CAN beat Omicron: Company says top-up dose bolsters protection from two jabs

Pfizer's Covid booster jab triggers a 25-fold increase in antibody levels against Omicron, company said today. The vaccine-maker said three injections provide a 'more robust' defence against the variant. Third dose triggers antibody response against Omicron similar to that seen against older strains after two jabs. South Africa study shows 40-times less Pfizer-triggered antibodies can fight against Omicron infection. Sweden found that drop in the body's ability to neutralise Omicron, but decline is smaller than feared. WHO official said Omicron is likely more transmissible than other variants, but data suggests it is less severe But Germany study found double-jabbed people do not produce any neutralising antibodies against Omicron
