The flu jab is about 65% effective so its better then that
Flu jab is based on predicted strain, so that's like comparing apples and oranges. The jab is very effective, but it might turn out that strains other than those in the jab might be the ones in highest circulation.
If they administered 2 jabs, then the effectiveness will be on a par with the mRNA jabs. is there any information yet on how it performs on the elderly, and if it is suitable for those who cannot have other live vaccines?
