I really recommend the Royal Institution Christmas lectures from the BBC... I've really enjoyed (my geek-ery coming out here) learning about why the coronavirus is so successful, why masks work, how we test (why is a PCR more sensitive than LFT) and then how vaccines work. There are over 3 hours of info/tests/experiments but it's really interesting. Including the professor who helped create the AZ Vaccine, Katie Ewer, (bit of a girl crush on her).
As someone who is generally nervous about vaccines (but I've had them all, whilst scared!) it really helped. They are very intelligent people, who cumulatively, have studied their fields for hundreds of years telling me why it's just science and, makes sense has really helped.
Anyway, they're here...
