Seriously though, we know that the data show that the vaccine reduces the likelihood of both infection and transmission. I've posted so many links to professional, expert sources, that are independent of one another, from many different countries around the world, from governments, universities, scientific bodies, etc.
Why would you think that being vaccinated increases the risk of spreading the virus? The thing that increases it is refusing the vaccine, refusing to wears masks and refusing to respect social distancing.
I don't know what you think about the role of vitamin D in all this. There are a lot of articles compiled in:
https://vitamindwiki.com/COVID-19+treated+by+Vitamin+D+-+studies%2C+reports%2C+videosThat it's a website run by a retired engineer, not a doctor, but not a kid writing from his mum's basement either, and he puts links to scientific articles, apart from videos etc.
I used to get colds 2-3 times a year, and the colds lasted quite a while. I say cold including flu or sore throat. Since I discovered vitamin D like 5 years ago, I have gone to having 0 colds. One a couple of occasions I thought I was starting to get a cold but it didn't last more than 24 hours, and it's a common thing that people who have optimal vitamin D levels say: that they don't get colds and if they do, they don't get them for long and with few symptoms. In principle, those studies linked point out that the same thing would happen with COVID-19.
The pharmaceutical industry is not interested in this because the sun is free and vitamin D as a supplement is cheap and it is not a drug that can only be sold exclusively by the industry, you can buy it in herbalists, for example.
