Immunity is seven times higher if you've had Covid and the jab, study finds
COVID immunity is seven times higher if you've had the bug and a single dose of Pfizer's jab, the largest real world study has found.
But in contrast, the experts noted a single jab in someone who hadn't been infected before didn't "neutralise" theRegardless of age, anyone who had the bug before having a single vaccine had an antibody response 6.8 times higher. Researchers found the cells - a key part of the immune system that hone in on specific foreign particles - developed a bigger recognition of more parts of the virus' spike protein, which launches the attack on the body.
"A second vaccine jab is crucial for longer-term protection, regardless of whether you have previously had Covid-19 or not, and I urge everyone to make sure they attend their second appointment – to keep themselves and those around them safe.”
