It did neither of those two things. Official UKHSA surveillance data from the UK Government showed that the vaccinated (per 100,000 in each age group) had more infections than the unvaccinated. The Australian data (and other countries such as Israel) showed that the vaccinated fared worse with Covid than the unvaccinated in most cases.
Okay, I've posted that image again. Look carefully at the 'Hospitalised with Covid' circle with intersecting 'Vaccinated' and 'Unvaccinated'. This accounts for people with more severe illness. You'll note that that rest of 'Vaccinated' bubble is significantly larger than the 'Unvaccinated', as most of the population has been vaccinated and do not require hospitalisation. This is due to the success of the vaccination program.
It was not a significant factor in slowing transmission, and was never tested or designed to do this (Pfizer's own disclosure). Any slowing of transmission correlates with degrees of seasonality (since the impacts of respiratory viruses are seasonal to a degree), the natural cycles of infection/reinfection of a virus, plus, most importantly, the increasingly acquired natural levels of immunity in the population, since, by early/mid 2021 almost everyone had been exposed to Covid by some degree. That said, Covid will be with us for a long time so those still proposing masks, zero Covid and other ineffective control measures are, how shall I be polite about this, totally barking mad!
Covid is not seasonal. I live in the southern hemisphere and had my first (and so far only) infection over Christmas 2022, in extreme heat. The lack of Pfizer testing for transmission doesn't make sense, anyway. Who would be the test subjects? And remember, this vaccine was meant to slow transmission rates and prevent severe disease - not stop transmission.
Strange that our news told us the opposite isn't it? But look up the stuff above and you might learn some fairly basic 101 level science. Science that was thrown out of the window in 2020 when weak politicians meet head on with corporate greed and corrupt scientists.
I'll throw that back to you. I don't think you're really here to learn anything, anyway.
