I doubt it to be possible, but it certainly wouldn't hurt to try. Even if you miss the moon, you learn from the process.

Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF OCTOBER 19 2025
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

The point is that it is not really a vaccine. A vaccine is against a specific threat, like this or that virus, and if it is good, against this or that virus class.
This stuff works by keeping your immune system on a hightened alert status, so it can react faster to any incoming, known threat. The known part is important here.
And if this "keeping the immune system on a permanent alert status" was any good on the long run, nature would long have normalized this, so there must be a severe drawback to it.
I read somewhere that when default body temperature was defined (100+ years ago), it was half a degree higher than nowadays, with all the hand washing, vaccines, etc. So maybe high alert used to be the norm.
Yes, an people died quite a lot of years earlier.
And then some MAGA will claim that it causes athelete's foot, with no evidence at all, and it will be banned.
I am going to laugh when your comment gets cited as the source evidence for why this causes acute athletes foot.
"I read it on the Internet, so that's a better source than YOU."
I wouldn't mind seeing a cute athlete's foot.
To be fair, some guy on the internet making promises does not constitute good evidence either.
Valid. We laugh at the snake oil salesmen of 150 years ago, but they are still among us, and they haven't changed, like, at all.
This would wreck the dow oh no
So the researchers are planning trials where one person is vaccinated and then deliberately infected to see how their body copes.
Umm... What? Excuse me, but when has this been legal?

Well at this point in a vaccine development it's already passed preclinical (animal testing toxicity) phase 0 and phase I trials (which determines their safety and dosing).
They appear to be already at phase IIIb trial which is to test effectiveness with a group of people who are already at risk of exposure to the virus. Without a global pandemic this is axtually one the hardest and most expensive part of vaccine testing.
One of the core reasons why the covid vaccines were so quick to be released was because there was a massive pool of people who were exposed to the virus (and who were willing to put there hand up to try it).
We knew already that RNA vaccines were safe and weren't deadly (as preclinical, phase 0 and phase 1 trials had already been done)
Take the Ebola vaccines. These have taken decades to develop because outside of the outbreak we had 12 years ago very few people are exposed to Ebola. It was really hard to find at risk individuals.
Also early Ebola vaccines used a live attenuated vaccine which had a one in a million chance that you get Ebola from the vaccine itself. So simply testing the vaccine could risk starting a epidemic
That said the latest, FDA approved vaccine is a replication-competent recombinant vesicular stomatitis virus (VSV) vaccine (basically using another virus to deliver targeting data to your immune system.
They've been doing that stuff to animals for decades. Time we all started sharing the load
I dunno, if the vaccine was "safe," and it really comes down to will this stop me getting a cold, I'd take one for the team. Maybe not the flu or COVID, although COVID never affected me so maybe I wouldn't be a good candidate.
We just need an island of clones that we can test on, because clones aren't real!
The approach described in the journal Science does not train the immune system. Instead it mimics the way immune cells communicate with each other.
It is given as a nasal spray and leaves white blood cells in our lungs – called macrophages – on "amber alert" and ready to jump into action no matter what infection tries to get in.
The effect lasted for around three months in animal experiments.
Ye$$$$, quarterly vaccination$$$
I'm no immunologist, but there has to be a reason why we evolved so our immune system doesn't constantly stay on "amber alert". There has got to be drawbacks.
So one of the reasons asbestos is so dangerous is that it gets in your lungs where macrophages detect it as being foreign and try to destroy it. The issue is that asbestos is way larger than these cells and it's pretty resilient so they can't break it apart and eat it. The cells "get frustrated " so they start releasing inflammatory substances trying to find a way to neutralize this foreign body. That prolonged inflammation is what eventually leads to mesothelioma and other cancers.
I'm not sure how they plan to avoid the inflammation caused by these cells being in constant fighting infection mode.
Hold up so I could have as much asbestos as I wanted if it weren't for my stupid immune system?
But the way evolution works is "whatever works that keeps the species alive".
We haven't evolved reading glasses, but they are helpful devices with very few downsides.
That said, there may well be unintended consequences and effects, sure.
I think of it this way. The immune system is like an army, ready to fight off foreign invaders. If you were a king, would you want a huge standing army at all times, or the ability to draft soldiers as needed? Having a huge standing army is not only a waste of resources if there isn't anything to fight, but your soldiers might get bored and invent things to fight or just stir up trouble.
So my guess is you'd be prone to inflammation and develop food sensitivities, but it's a total guess. If they were the case though, chronic inflammation is really bad long term.
Yes, I understand the theory. And it's fine to discuss speculation, because that could turn out to be the case.
But I also brought up glasses because not everything the body has done to survive is something that can't be changed.
We'll have to see what happens when we turn up the immune system.
As a hopefuly kidney transplant candidate at some point… I'm very interested as I know after a transplant, I have to take things to suppress my immune system, so I particularly suspect for that reason I might not be able to benefit from this new thing..... but I hope I'm wrong :)
Probably why there are auto-immune disorders, no? When the body randomly chooses to attack itself. Not a scientist so just speculating.
On one hand I can see the benefit of using such a booster right before flu season. On the other hand, yeah does it have a crash at the end? Does an overactive immune system damage healthy tissues? Does it create inflammation response that leads to depression, fatigue, other chronic issues? There is A LOT that can go wrong there.
Sure. You wouldn't want it all the time. Aside from auto-immune issues even simple things like allergies might be worse
But if we think of it as a booster it could be useful. Someone in the household comes down with something, then everyone else does a quick squirt with the immu-alert nasal spray.
I’d be really worried about autoimmune reactions. I swear there’s been a few Trek episodes where some kind of universal vaccine has unintended consequences.
I'm not sure I'd put any truck into fictional sci-fi where everything needs a good story, so any positive needs a negative…
…but I get it. And yeah, it's a worry.
Same. Every major corona infection I suffered has set off my immune system for months, leading to debilitating nerve and joint pain. Even some vaccinations trigger this, but with shorter and way less symptoms, modern vaccines are way better than what they prevent. So I have high hopes.
I get a light version of the flu for about a day after getting the flu vaccine despite everyone saying the vaccine doesn’t give me the flu. Low fever, achy joints, tiredness, sometimes even congestion.
Can you please CW this post, for people like RFK this could be really triggering of their emotions.
