This is a really great video! I really appreciate the time you must all take to make them! Just to point out, there's a spelling mistake at 0:15 - it should be 'immune', not 'immue'(!) Short rant over; I love your videos! Thank you!

the content is relatively same, it really only depends on if you're doing core or extended. And whilst this channel is a great resource for revision/understanding of concepts, I'd suggest you'd refer to the textbook alongside.

Notice how science has changed over lockdown.

thank you very much

0:23 Ok so Im confused when you get the vaccine I thought you could get the disease just your immune system was more effective and quicker at responding to the disease and eliminating it. I got covid once, got vaccinated for covid and straight up got covid again but it was less bad. I also thought when you are vaccinated you can transmit the disease to others but you are less likely to because your body fights it quicker, so the transmission rate falls bellow 1 and that’s herd immunity. Vaccines would also mean there is a shorter period of time where the virus can mutate.

Fevers, and seizures. BARZ

At around time stamp 0:30, "IMMUNE SYSTEM" is misspelled.

Vaccine good. No vaccine bad

is pandemic another word for epidermic?

Question about the sprites you've used for this video. The pathogen one, is it smiling or frowning 00:23 ?? I see a lil dude with a a funky haircut smiling away with his big turquoise mouth and his defined lips. He's got a small button nose with even smaller even eyes and cute lil upturned eyebrows. My friend sees a very angry little gremlin with a visor for eyes and forehead with acne. Who is correct? Respond as soon as you can. I am waiting desperately. Respond plz I think im gonna lose my dear friend over this dispute. Plz be quick...
