Fourth shot of Covid vaccine is NOT enough to prevent 'lots of infections' from Omicron
Daily MailEven a fourth dose of a Covid vaccine isn't enough to stop people getting infected with Omicron, according to the preliminary results of a trial. The fourth dose of the Covid vaccine is less effective on the Omicron variant and provides only limited defence, a preliminary study in Israel has found Israel was the first country in the world to roll out boosters last year and became one of the only nations in the world to start dishing out fourth jabs last month to combat Omicron. UK EXTENDS PFIZER'S SHELF LIFE AMID SLOWING BOOSTER ROLLOUT Health chiefs in the UK have extended the shelf life of Pfizer's Covid jabs over fears millions of injections would have to be binned.
