And this might be why we're seeing lower effectiveness:
Remember, this is the fault of the West for thinking it's all a joke and that they're more alpha than the Asians who take things seriously.
In the past few days, MSM are attacking Chinese vaccine as low efficacy/useless. Look like all vaccines have the same fate. As long as I know, vaccines take time to take effective. For example, I took 3 shots of Hb vaccine with interval of one month to three months, then, six months later I had a blood test to find if it had generate enough antibodies. Within a few days, you can't expect vaccine to be effective.
Or it has nothing to do with the new virus strains.
The new virus strains have just become a convenient excuse for the clinical trial efficacy rate of the vaccine not proving itself to be what it's been claimed.
