    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.

    • @Sonia.A.15
      @Sonia.A.15 3 місяці тому

      I think that since covid is one of the more recent viruses, the vaccine is still worked upon and there may be imperfections. Probably why there were 2 vaccinations and a booster - but idk, I'm still doing my gcses 💀

      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.

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.
