The Covid virus has since mutated substantially, with a stream of new variants emerging that can dodge some of our immune defences. They have caused large surges in cases around the world.The Covid virus has since mutated substantially, with a stream of new variants emerging that can dodge some of our immune defences.

The results of experiments on 437 people showed the updated vaccine was safe and gave better immune protection against newer variants.The results of experiments on 437 people showed the updated vaccine was safe and gave better immune protection against newer variants.
Levels of antibodies that were able to stick to and disable Omicron (BA.1) were eight times higher with the new vaccine than Moderna's old one. Levels of antibodies that were able to stick to and disable Omicron (BA.1) were higher in people given the new vaccine. Tests against more recent Omicron variants (BA.4 and BA.5), which are causing the UK's current wave, also showed higher levels of protection with the updated vaccine.

However, while there is better protection against known variants, it is uncertain what we will be facing in the coming months and exactly how well the updated vaccine will perform.However, while there is better protection against known variants, it is uncertain what we will be facing in the coming months and exactly how well the updated vaccine will perform.

Originally those aged 50-65 were not going to be jabbed. However, the immunisation campaign has been expanded because of the fast spread of variants, uncertainty about how the virus will mutate and the expectation that we will be more social this winter than in previous years - giving the virus more chance to spread.Originally those aged 50-65 were not going to be jabbed.
