If you got AZ as your vaccine, get your booster as soon as you can. (The government doesn't give a shit, it urged all of us to get AZ, often only 3-4 weeks between doses.) These graphs show risk of severe disease and death for those catching Covid in Scotland and Brazil, for people who had 2 x AZ. For example, those who had AZ in Scotland were about 7 times more likely to be hospitalised or die with severe disease after 5 months. This is for Delta, not Omicron. Brazil slightly better because they had much less Delta. Do NOT take your advice from politicians, who continue to tell everybody the vaccines protect you from severe disease and death. They definitely do much better than no vaccine, and Pfizer and Moderna better than AZ, but all show waning protection against severe outcomes and death. We don't even know how bad Omicron is yet.
