I hope you booked your 4th booster.
I don't argue with anti-vaxxers because the majority of you don't know much about the nature of viruses; how vaccines work, and know how to interpret data and scientific research papers. So there is no point in discussions. Its obvious in this thread.
So let me break this down to something your ilk will understand.
If I need a 4th dose I will get it. Why will I get it? If I get the virus, I don't want to spread it to my 86 yr old neighbour, who has medical conditions and my parents who are also in their 80's. I don't want to spread it to my other neighbours young kids who can't get the vaccine. I also wear masks and social distance so that I don't spread it to those that are vunerable that I come in contact with. I don't have to get the vaccine because I am metabolically healthy and my chances of dying are close to zero.
However, I am also aware that I can get seriously sick which may affect the quality of my life. I may not die, but I may have diminished lung capacity which will prevents me from going on my 1hour daily jog, and HIIT workouts which I love to do. That is why I laugh when anti-vaxxers use the low mortality rate to claim that the virus is just the same as the common cold.
You are correct. Vaccines will not stop covid. It is from the same family of viruses as the common cold. The common cold has been around for epochs. Vaccines will not stop the spread, but it will decrease the rate-of-spread. Vaccines will buy science time to come up with treatments to this virus. These new treatments is what will get us back to living normally.
I don't watch CNN, FOX or any other news network. I don't listen to so-called internet experts. I knew from the very beginning that we would need multiple vaccines because I researched viruses and their evolution, and vaccines from scientific papers like JAMA, Harvard medical journal...etc. That is my source of information. So when they announced that we would need a 3rd booster, it didn't surprise me at all.
