@freemo from what I understand
Just because you are vaccinated does not mean you can't host the virus and pass it on to others.
Vaccination simply helps the body build the immune system by being presented with an inert version of the virus, as far as I understand the body can then produce antibodies that recognise the spike proteins.
The body can then recognise the virus and, hopefully produce the correct response.

When vaccines work they are usually great at stopping the spread. For the original strain of covid, for example, it both stopped symptoms **and** stopped the spread.
The new variants however (such as delta, the most prevalent one, and omicron) it is either completely in effective or significantly less effective (hard to draw firm conclusions off what studies we have). The point is, its not effective at stopping the spread because the spike protein it encodes for is different in the variants and thus the antibodies are ineffective to a significant degree (if not completely).
@freemo @khaosgrille Ah ok thanks, that clears a few things up.
I still think it is worth wearing a mask most of the time anyway, esp in crowded places such as shops etc.
yea masks im not sure about. The data in them are questionable in either direction so we can only speculate about how or if they are effective.
I think if you are very strict in how you use them they probably help, but most people, almost no one, handles mask with the level of rigor needed for them to be effective.
Indeed, the ones I wear are just basic masks, so slip down, so i need to touch them to reset to the right place.
also soap is still a good thingie.
well im in germany we have no kids anyway and everyone is 60+ years old
Back in the 1920s there were other health risks too, TB etc, so having mild TB then gettign the flue could make the former worse (just speculating) but combine that with air pollution, etc, people having coal fires at home, or cold damp homes, and it is a lethal combination.
Thankfully things like TB / Polio have been wiped out pretty much in most countries)
Quite the opposite, the studies are exceptionally weak in nature. Virtally all use uncontrolled observational data subjected to confounding. Essentially they are prime examples of the post hoc ergo procter hoc fallacy. The few lab controlled studies we have (and they do exist) do not factor in the points I mentioned earlier.
So I think there is some decent evidence to show that a doctor using rigorous guidelines in how they conduct themselves in a surgical environment is certainly going to see a protective effect for their patient I dont think there is any good evidence this would carry over to the non-rigorous environment of the general public where none of the usual good practices are maintained.
Its like saying "condoms are proven to work"... well yea, but not when you reuse them a dozen times and take them half-off half a dozen times during sex.
