Very good informational video about Covid-19 variants vs vaccines, plus discussions about natural Covid-19 immunity and vaccine-generated immunity. Speaker is Prof Shane Crotty (virologist and immunologist at La Jolla Institute in California). Lots of questions answered, I think everyone can learn something from this.
Topics:
0:00 Intro
0:46 Heated exchange between Dr. Fauci and Senator Rand Paul
1:00 How long does immunity last for those who’ve had COVID-19?
3:31 How antibody levels and T cells drop over time
4:03 Dr. Fauci: Difference between in vitro and real-world studies
4:36 Population-based studies about COVID 19 immunity against reinfection
6:22 Huge variability from person to person for post coronavirus immunity
8:20 Policy decision: individual vs. community goals during a pandemic
9:03 Very rare for hospitalization from COVID-19 reinfection
9:34 Avoiding COVID-19 infection and transmission potential
10:12 Should mask-wearing continue for those who’ve had COVID-19?
12:23 If I’ve had COVID-19, shouldn’t my vaccine dose go to someone else?
13:39 Vaccines are eliciting more immunity than natural infection
14:02 Is natural immunity always better than a vaccine?
20:05 If you’ve had COVID-19, when should you get vaccinated? Both doses?
22:07 How are variants “game changers” for vaccines and natural infections?
24:53 Can’t I stop wearing masks and distancing after a vaccine or having COVID?
26:14 Variants of concern: B.1.1.7 (UK) and B.1.351 (S. Africa) details and implications
30:57 South Africa Variant escaping immunity: AstraZeneca Vaccine data
32:28 Isn't preventing COVID 19 hospitalizations and deaths the primary goal?
35:25 Will we need updated coronavirus vaccines?
36:38 Johnson and Johnson vaccine versus the variants
37:57 Preventing transmission to prevent SARS CoV 2 mutation opportunities
38:40 Coronavirus antibodies vs T Cells and other parts of the immune system
39:54 Replication and asymptomatic spread of COVID-19 vs. Pneumonia
42:53 Vaccine incentives and Senator Rand Paul's perspective
45:35 Looking ahead, SARS-CoV-2 vs Influenza, Will we need annual vaccinations?
52:20 Current research and goals for Prof. Shane Crotty
