What is the current medical thinking for the future?
I understand that the current annual flu jab is slightly different each year and based on the strain experienced in Australia in their earlier winter. Sometimes the strain that arrives in Europe is not the same and so the jab is less effective.
Now I know that flu and Covid are not the same but with Covid developing variants and uncertainty about how long the current vaccines will be effective for and differences between them - I was wondering what the current medical thinking is on the need for future - maybe even annual - vaccination?
