How do we know that we are not some of the 15% for whom it doesn't work. The antibody test isn't being offered is it?

The efficacy depends on which vaccine you are given and how old you are.
The Government clearly does not care about the overs 80s who have only
had one dose. There is also the problem of different mutations.

In the case of the Russian Sputnik V vaccine, the two doses are
different to overcome the problem of the 1st dose in your body attacking
the 2nd dose as it appears. (AIUI the Russian on Radio 4 yesterday)

Why would the first dose attack the second dose?


I don't know anything about Sputnik. The Oxford vaccine is carried into
the body by a harmless virus. Harmless or not, the body recognises that
virus and organises the usual defences. What you don't want is for the
virus carrying the vaccine in the second dose to be killed before it can
do its job.

That's my understanding, which may not be quite accurate, so do correct
me if I'm wrong.

This being usenet, do correct me even if I'm not wrong.
