Here's one of the bigger takeaways from this study that you posted. Here's an excerpt from the study.
A marked reduction in infections was also seen when analyses were repeated with: (a) inclusion of HCWs testing positive through both the symptomatic and asymptomatic arms of the programme (56/3,282 (1·71%) unvaccinated vs 8/1,997 (0·40%) ≥12 days post-vaccination, 4·3-fold reduction, p=0·00001); (b) inclusion of PCR tests which were positive at the limit of detection (Ct>36, 42/3,268 (1·29%) vs 15/2,000 (0·75%), 1·7-fold reduction, p=0·075); and (c) extension of the period of analysis to include six weeks from December 28th to February 7th 2021 (113/14,083 (0·80%) vs 5/4,872 (0·10%), 7·8-fold reduction, p=1x10-9). In addition, the median Ct value of positive tests showed a non-significant trend towards increase between unvaccinated HCWs and HCWs
> 12 days post-vaccination (23·3 to 30·3, Figure), suggesting that samples from vaccinated individuals had
lower viral loads.
We therefore provide real-world evidence for a high level of protection against asymptomatic SARS-CoV-2 infection after a single dose of BNT162b2 vaccine, at a time of predominant transmission of the UK COVID-19 variant of concern 202012/01 (lineage B.1.1.7), and amongst a population with a relatively low frequency of prior infection (7.2% antibody positive).5
They continually mention protection from symptomatic and asymptomatic SARS-CoV-2 how did they even confirm asymptomatic infection since it's asymptomatic? The now admitted PCR tests that were being run at cycle rates of 40 making them meaningless and since the CDC has lowered the PCR cycle rates in January. And as you state there is no data about whether or not vaccine recipients become aymptomatic carriers and transmitters of the virus. Here is a news report that seems to address this issue.

Thanks for posting the two studies I will continue to read them and digest the information. I hope you read the 2012 NIH study that had actual animal trials for the tested SAR-COV vaccines in those studies, it is unclear in that study if it was an MRNA genetic therapy or a traditional attenuated virus vaccine.
