Most arguments for the efficacy of vaccines, are based on past performance of famous vaccines such as smallpox and polio and are touted by ignorant people like yourself who have never seriously investigated this topic.
The WHO has claimed that smallpox was eradicated due to the vaccine but there are major problems with that claim.
1. Smallpox still exists. It is today called monkey pox and the WHO says these two diseases are "indistinguishable" from one another. Meaning of course that they are in fact the same disease. Therefore, it hasn't been eradicated, just relabeled.

2. The epidemiological studies on smallpox show that vaccination at best had a 3-5% reduction effect. Proper sanitation and bed bug control was far more significant. The so-called "herd immunity" for any disease is said to require up to 90% vaccination rates. Smallpox never achieved more than 10% vaccination rates. So much for "herd immunity."
3. There were countries and groups which had over 100% smallpox vaccination rates and suffered the worst smallpox epidemics both in raw numbers and death rates. Japan, the Philippines and the British navy are the best known examples of this.
4. The smallpox vaccine does not contain either attenuated or live smallpox virus. It contains cow pox (attenuated) virus and could never provide protection from smallpox if vaccination as a theory had any merit.
In the late 1800s, Dr. Crighton of England, after Alfred Wallace published "Vaccination proved useless and dangerous (
A Summary of the Proofs That Vaccination Does Not Prevent Small-pox but Really Increases It, by Alfred Russel Wallace)" - a paper which caused England to suspend its forced vaccine program - called vaccination a "grotesque superstition." This is an apt description and proponents today have no better evidence than was presented in Wallace's day.
There has never been any evidence that vaccination of any kind provides immunity. Vaccine manufacturers admit that unlike getting a disease, vaccines do not and cannot provide permanent immunity which in practice means that they can't provide any immunity at all.
As far as flu vaccine goes, it has the same problems that the smallpox vaccine had. In many cases people get the flu after taking the vaccine. It's not clear that they contracted it from the vaccine or suffered a reduction in immune response. But the manufacturers cannot be sued when their vaccines kill or maim. One has to file a complaint with the VAERS system and restitution is slow and limited.
You sir, have no idea what you're talking about.
