I look forward to it being peer reviewed, but the early results are promising. I am optimistic that we will beat this.
"The recently authorized BNT162b2 COVID-19 mRNA vaccine is about 95% efficient in preventing disease after 7 days from the second dose, and also provides some early protection starting 12 days after the first dose 1,2 . As countries race to vaccinate a significant share of the population within the coming months, the basic reproduction number of the virus is hoped to decrease. This effect can be achieved by reducing the number of susceptible people, as well as by reducing viral loads and thereby viral shedding of post-vaccination infections, turning them less infectious 3–7"
That sounds like cause for celebration to me.
"However, the effect of vaccination on viral loads in COVID-19 post-vaccination infections is yet unknown 8 ."
And cause for further study.
