Vaccines aren't that great to stop the spread. We have ample evidence of the fact by looking at the winter 2021 numbers in highly vaccinated regions. They are even less effective against Omicron.
Omicron is mild anyway. Heaven forbid that students will experience a "a sore throat, runny nose and a headache":
Why is this one being downvoted when in fact what OP is saying is a 100% truth? Vaccines won't stop the spread because it's a sliding window problem. You vaccinate 10m people today, then you vaccinate 10m people tomorrow, by the time you vaccinate another 10m, the first 10m already lost their antibodies. We'd have to vaccinate the entire population within 4-6 months, which is impossible given the current state of things. There are no transactional guarantees, so to speak.
On top of all of that, vaccines do not stop the spread, but just ease out symptoms. You can be vaccinated and your symptoms can be so mild that you won't even know you are sick. So you'll walk around infecting others.
Because "stop the spread" is a very nice goal, but not the actual one. "Slow the spread so hospitals can handle the load" is closer to the real goal. Without the vaccines, too many people get sick at once and more people start dying.
On top of that, it's not just the vaccinations. Those who get the disease are also helping to slow the spread as they build their own resistance.
There's been enough resistance to the vaccines that it's probably impossible to end this with the best possible result, so we're going for second-best now. And that still involves keeping as many people vaccinated as possible.
Looking for about half a dozen papers confirming your following words
> You vaccinate 10m people today, then you vaccinate 10m people tomorrow, by the time you vaccinate another 10m, the first 10m already lost their antibodies.
>For most, Covid is a mild disease. Some get no symptoms at all. But it can still cause very serious illness in some people, including those who have not been vaccinated.
>[A] massive wave of infections would still mean many people needing hospital care, as well as lots of doctors and nurses being off sick with Covid.
I would like to share this link with you, which explains the effectiveness of vaccines against infection:
“Breakthrough infections are not evidence that vaccines don’t work anymore than the fact that car crashes [that] are still sometimes fatal is evidence that seatbelts don’t work. We use prevention tools because they help reduce our risk of serious disease or death, not because they are guaranteed to 100% always keep us safe,” Murray [, an assistant professor of epidemiology at Boston University School of Public Health] said.
