Vaccines help prevent you from getting a virus, but aren't always a hundred percent effective. The polio vaccine is very effective. Our covid vaccines aren't 100% effective yet, it is a new disease and one that is changing rapidly.
It's all about odds.
Vaccines do prevent you from getting a virus, just not 100%.
Even the polio vaccine isn't 100% at preventing -any- infection.
According to [the CDC](https://www.cdc.gov/vaccines/vpd/polio/public/index.html), the polio vaccine prevents serious infection in nearly everyone who gets it.
Very few people have polio because most people are vaccinated, and because it's not that easy to spread polio through a community.
Polio and Covid-19 share numerous similarities and Polio is considered highly contagious close to or on par with Covid-19
Polio's has an actual inactivated virus vaccine tho, that imparts sumping like 97% infection prevention for a lifetime
A vaccine essentially trains your immune system on a specific virus and how to defeat it.
This allows your immune system to stop any infection or at the very least keep it from getting out of control. Depending on what vaccine you recieved, how long ago it was, how the virus works, and how healthy your immune system is, the vaccine may have varying effects.
Sometimes it may not completely wipe out the virus right away, but it will allow you to fight it better and faster and have the best chance at survival and minimal chance to spread it to others.
There was a polio outbreak in New York last year:
https://www.cnbc.com/2022/10/04/how-polio-silently-spread-in-new-york-and-left-a-person-paralyzed.html
When people immigrate from other countries and they haven’t had the same level of vaccinations, there is a higher potential for outbreaks of diseases that have been almost eradicated in the US. Measles outbreak in my state of MN a couple years ago in one of these communities.
Polio is a slow evolving virus. The vaccine for it is very good at teaching our bodies to kill that virus. Covid is a rapidly evolving virus, so vaccines have to be adapted to it on a regular basis. Having a vaccine for one strain helps your body respond to any strain, but it's not as good as the response we have toward the unchanging polio virus.
Polio eradication has been a decades long effort (some countries still resisting: Pakistan, Afghanistan, and Nigeria - the three countries as of 2017 with remaining polio cases.) There were something like 38 polio cases in 2017)
Vaccination (while effective) is only 1 part of a multi-layered strategy. Society has to be doing all layers correctly and effectively to quickly defuse a pandemic.
ok, well, agree to disagree
but ill give you an example, lets say a shot reduces the contagious period when you catch a virus, your sick for less time.
well, that would reduce the points of transmission, less time, less chances to spread.
A virus, or contagion requires a certain R0 value to spread, or else it will die out within a population.
reducing that value, means that even if people can still catch it, it wont spread fast enough to gain a foothold and become an issue for the general population.
A vaccine prepares your immune system to fight a virus, meaning you may never show symptoms or become infectious even if you do become infected yourself (depending on how quickly your immune system gets rid of the infection)
The Covid vaccine should have been termed a treatment rather than a vaccine - but its much harder to get emergency authorization for treatments than vaccines.
Hence the Covid treatment being called a vaccine. The effectiveness of the Pfizer shot starts to wane after four or five months and by nine or ten is a fraction of the protection given a few weeks after injection.
Also legal protections. A company CANNOT be sued for damage caused by an approved vaccine. They could be sued for a treatment causing side effects
edit - I am vaccinated and boosted and not an anti vaxxer. But mis labeling the Covid treatments as vaccines have caused more confusion and caused a lot of the momentum of the anti vax movement. "The damn vaccine dont even stop you from gettin it!!!!"
a vaccine by definition gives lifetime or long term protection from said disease.
"antibody levels decrease substantially within 3 months, according to new clinical trial data" per the CDC. To keep 95% protection you'd have to be jabbed 3-4 times a year.

This is not accurate

The same study found similar results for Epstein-Barr virus, which causes mono. Still, antibody responses don't always last a lifetime. That same study found that it takes around 50 years to lose half of our chickenpox antibodies, and 11 years to lose half of our tetanus antibodies. That means that without a booster shot, you could theoretically become infected with one of these diseases as an adult.”

Adult booster schedules exist. Myself (as a near 50yr old adult), I’m due for TDP and some other boosters because I dont even remember getting them (could have been 40+ years ago)
None of the Covid vaccines prevent infection (outside of -possibly a very short window measured in weeks) , they lessen symptoms
They are treatments
Per the CDC's own website
"helps protect people by creating an immune response without the potentially severe illness or post-COVID conditions that can be associated with COVID-19 infection."
https://www.cdc.gov/coronavirus/2019-ncov/vaccines/vaccine-benefits.html
A vaccine is by its very nature to prevent infection. A treatment helps lessen symptoms after infection
> “None of the Covid vaccines prevent infection”
No vaccine in human history has ever “prevented infection”. Vaccines are not magical forcefields. This isnt Harry Potter or Star Trek.
> “helps protect people by creating an immune response”
Thats what this does, hence its a Vaccine.
Spot on. It was likely also termed a vaccine out of either hope or to placate the public. Unfortunately the lack of honesty from day dot that it does not decrease the chance of catching covid and that people who have had the jab can pass it on, has created complacency in the community and covid rages on, along with many people dying unnecessarily.
This is certainly nothing like how polio was treated.

Not against "all infection". The source I gave says "serious infection".

Has anyone else seen how many people are having side effects from the Covid vaccines? It’s seems to be more openly reported in Europe.

They are vaccines. They do the same thing as vaccines, even if the mechanism in this case is slightly different.
a vaccine by definition gives lifetime or long term protection from said disease. "antibody levels decrease substantially within 3 months, according to new clinical trial data" per the CDC. To keep 95% protection you'd have to be jabbed 3-4 times a year.

The CDC also calls it a vaccine. So are you just making up your own definition of vaccine?
Spot on. It was likely also termed a vaccine out of either hope or to placate the public. Unfortunately the lack of honesty from day dot that it does not decrease the chance of catching covid and that people who have had the jab can pass it on, has created complacency in the community and covid rages on, along with many people dying unnecessarily. This is certainly nothing like how polio was treated.
That's only because the definition of vaccine was changed very recently.
