Further tests are ongoing to increase confidence in the data that suggests a half dose followed by a full dose results in 90% efficacy. They’re concerned that the small sample of people given the half dose were all under 55 years old and might have been expected to show a stronger immune response regardless.
Nonetheless the vaccine has already been put forward for emergency approval. |
Just a guess but I would imagine different population groups might get different vaccines and possibly even different dose regimens. If the 'one and a half' regimen works well for under 55s with no evidence to date to show effectiveness for over 55s, that's workable as a 'Tesco Value' vaccine for the general population for under 55s.
