Two separate U.S. teams have reportedly made progress on creating a universal influenza vaccine, according to the BBC:
Researchers say they are closer to developing a vaccine to give life-long protection against any type of flu, after promising trials in animals. Two separate US teams have found success with an approach that homes in on a stable part of the flu virus. That should remove the problem with current flu vaccines which must be given anew each year because they focus on the mutating part of the virus.
The proof-of-concept work is published in Science journal and Nature Medicine [both paywalled]. Studies are now needed in humans to confirm that the method will work in man.

There are no more smallpox infections and rabies, a nearly 100% fatal disease, is successfully treated with a vaccine. Those are two obvious examples that vaccines work.

I'm not sure it maks sense to talk about vaccines as some monolithic entity. There is no contradiction if vaccine A being 100% effective, safe, and cheap, while vaccine B is an expensive death injection that does not even offer any protection.

Vaccination is a successful strategy to prevent disease and mechanism of protection is understood so well that they can be rationally designed. Any medical treatment has variability in the way that it is administered and its effect on diverse groups of people with various statuses of health or history.
People should be smart enough to understand that "vaccines work" does not mean "every single vaccine, from the dawn of time, has always worked with 100% efficiency and with absolutely no side effects".

I don't think there has ever been a rationally designed vaccine shown to be successful, which ones? Noone even knows where the smallpox one came from, the usual measles one was taken from a sick child and then modified in unknown ways in cell culture...

Did you read TFA?
If you mean in use, then there is the recombinant canarypox vaccine for rabies. Subunit vaccines, such as HBV and HPV, are used to generate antigens that will produce neutralizing antibodies. Seasonal influenza vaccines are specifically recombined with high-yielding egg strains to maximize production while preserving HA neutralization. A VZV-vectored ebolavirus vaccine is in trials now and has demonstrated efficacy.

You think these flu vaccines have been shown successful? That is extremely low standards, using your standards we should believe in all sorts of paranormal crap. Make it easier for me by linking the exact papers you are referring to for one of the other cases. I do not believe any of those has really been tested, but could be wrong.

Why would you not believe that the currently used HBV and HPV subunit vaccines have been tested?
"2012 meta analysis found that flu shots were efficacious 67 percent of the time"
Not exactly paranormal.

A quick glance at the ebola vaccine paper brings up some oddities:
So what we are seeing in figure 3A is *eligible* people in the delayed vaccination group vs *vaccinated* in the immediate vaccination group. Now look down at figure 3C which is eligible vs eligible. Why are there no cases even amongst the unvaccinated people assigned to the "immediate" group? We are talking about 1000 people here, when they were seeing infection rates of 0.5-1%, there was something else different about these two groups of people.
The other problem is that figure 2 shows 446 confirmed cases, of which 5 were later excluded because the tests were later negative. That means there can be up to 1% rate of error in diagnosis. This is of the same order of magnitude as the infection rate they observed, yet they do not take this source of error into account at all.

The nesting with two ACs is getting ridiculous, but there was an error in something I wrote:

That refers to after day 19. There are no more cases even amongst the 1000 unvaccinated people in the "immediate vaccination" group after day 19, while diagnoses continued in the case of the "delayed vaccination" group.

Wow, just like for Zmapp these immunology researchers decided that blinding was unimportant:

You are going to snarkily argue in favor of not blinding the people who determine your primary endpoint? Also afaict the Science paper does not claim blinding either way, so it is possible they have the same problem. Medical research practices need to be cleaned up. Big Time.
