[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]OP, there are two types of immune responses: innate and adaptive.

Innate immune responses are generalized, not specific to the antigen. They unfold the same way every time. They also happen immediately. Fever is an innate response.

The adaptive immune system is antigen-specific. Adaptive responses include making the specific antibodies needed to neutralize this antigen, and developing the specific memory cells that help your body recognize and defend against that pathogen in the future. Because the adaptive immune system is quite complex, and involves some degree of “learning” it takes quite a bit longer than the innate responses. [/quote]

This is OP and this is what I was looking for. I had no idea. Thank you![/quote]

AND THIS IS WHAT IS SO SAD ABOUT OUR PUBLIC HEALTH AND EDUCATION IN THIS COUNTRY. I would even bet the OP is college- educated. FFS. [/quote]

The info is there and available to anyone who wants it, but vaccine misinformation is just everywhere and unrelenting and it drowns everything else out. The idea is to create doubt so hesitancy seems “reasonable”.

It can also be confusing when some vaccines, like rabies, are prescribed only after exposure (excepting vet staff who are exposed regularly). Even the MMR and Tetanus vaccines can be partially effective when taken after exposure. It can be very easy to miss that for COVID and flu, waiting until you’re in the throes of it is too late.

This is OP. Maybe I'm just very bad at Googling, but I didn't readily find the answer to my question. Here are the types of info I found, from CDC, for example:

"Sometimes after vaccination, the process of building immunity can cause symptoms, such as fever. These symptoms are normal signs the body is building immunity."

"Many people have reported common side effects after COVID-19 vaccination, like pain or swelling at the injection site, a headache, chills, or fever. These reactions are common and are normal signs that your body is building protection."

Those are not nuanced enough to answer my specific question.[/quote]
Yes, I know. Thats what I am so utterly pissed about our education system- especially with Public Health. People want to know more and they should understand how it works instead of just being told to do it. People need to learn how immune systems work- to the best of our limited knowledge. By not being super explicit and having kids learn about this in ES/MS/HS that grows with them to adulthood, its super simplified over and over again with no real education.

It's really hard to find digestible information on immune cells, the immune system as explained by the PP above, how they work, a sequence video on vaccination and what it does internally and why it might "fail" and what success means, replication videos and how transmission is affected by increased vaccination rates.

I agree with the PP that vaccine education is really weak. My kid went to the Takoma Park Math and Science Magnet (pre-COVID) where he was taught health by a vaccine-denying former nurse.  Doh! Forehead smack!  It's a good thing that it was a math and science magnet because those smarty-pants magnet kids definitely told her she was wrong and explained to the whole class, magnet and non-magnet, all about how vaccines work.

It's not a surprise that the CDC doesn't post good vaccine explanations (RFK aside).  I find that a lot of what is wrong with today's political and policy messaging is that there is no space for longer explanations -- news or policy sources don't produce it and people don't consume it or the response is to demonize the messenger or both sides an issue instead of focusing on the explanation and addressing further questions.  I don't know how we as a country get out of this dumbing down of everything.  [/quote]

Yes, the CDC article was from September 2024, which predates RFK.[/quote]
