Please allow me to go back to this question of "do vaccines prevent transmission?". What do vaccines do? Stimulate antibody (from B cells) and T cell responses (not often measured) and then a "boost" of 2nd dose helps stronger memory B/T cell to form.
Once you get vaccinated, should be able to block both the entry of the virus into your body & we certainly know symptomatic disease blocked by 95% (Moderna/Pfizer). However, latter trials just didn't look at asymptomatic infection & didn't swab every week because time of essence
But Oxford/AztraZeneca trial did swab every week & asymptomatic infection reduced substantially so we can say with relative confidence now that what is EXPECTED to happen will happen- the person who got the vaccine is safe from disease (what really matters) & spreading to others
No time in history do we have this extraordinary detection of asymptomatic infection since latter can transmit to others. So, please be assured that YOU ARE SAFE after vaccine from what matters - disease and spreading. Two vaccinated people can be as close as 2 spoons in drawer!
Also, a broadcasting friend texted me yesterday and said I am too wordy which I am but one concern I have is that sound bytes these days with COVID don't work. It is nuanced & hard & a weird virus so takes lengthy overblown academic explanations!
