Not me getting Whooping Cough twice, nearly a decade apart, and nobody understanding why because you're not supposed to be able to get it twice.
This video is very interesting.

Great video! Love the animation and the detailed info on PAMPs and DAMPs.
I go into great detail with a medical doctor on the immune system as well. Check it out on my channel: FredricksonHealthSolutions

About the Flu Vaccine, even though we need a new vaccine every year, it's not for ourselves. It's so we don't spread it to the imunocompromised who are ineligible for the vaccine.

@kayalguhadas

They conveniently left out telling us the difference between imunology (where you naturally come in contact, your I.S. builds antibodies to the antigens and now you have life lont immunity... VS. Vaccinated. Unnatural, by passes the micro-biome and never educates your immune system to give you life long immunity. (hence booster shot)

This and the other Immune System videos are some of the best in the whole A & P series. Great explanations and animations to describe adaptive immune responses to specific germs on a systemic level. Thank you!
