Got a COVID vaccine? Here’s how it changes the risks of infection for you

ABC  

It's understandable to be confused about exactly what sort of protection you'll get from a COVID-19 vaccine. Key points: Data from the UK shows both AstraZenecca and Pfizer vaccines stop about 80pc of infections A person who becomes infected after being vaccinated is half as likely to pass the virus on to the people they lived with The Pfizer vaccine is known to be 97pc effective at keeping infected people out of hospital Plenty of people have contacted the ABC with questions – how come we're hearing about vaccinated people getting COVID? When there is a lot of virus around, some vaccinated people will still get infected, but in most cases vaccinated people experience mild symptoms – we'll come back to that later. Unfortunately, the Centres for Disease Control in the US now thinks people who get infected with the Delta strain after vaccination might spread the virus just as easily as people who haven't been vaccinated. Data from Israel showed the Pfizer vaccine was 97 per cent effective at keeping infected people out of hospital, while another study from Britain showed AstraZeneca was 92 per cent effective and Pfizer 95 per cent effective at preventing hospitalisation after infection with the Delta strain.
