- Viral evolution
adenine, cytosine, uracil, guanine
Darwinian evolution
Species undergo random mutation
Making most less fit
But making a few more fit
Fit means compete, survive, reproduce
Natural selection will ‘select’ the more fit
Viruses usually become less virulent over time
Increased virulence / transmissibility
Mutations that increase transmissibility
Mutations that can avoid antibodies
Mutations that can avoid vaccination defences
Amazing. In less than 30 minutes you assimilated a full year of “genetics, biochemistry, virology, and immunology” in college. Great review for this old health care provider.
Great educator often go unheralded. 😉👍♥️
This a living library where most of us resource to get what to share to our listeners... Folks! This library updates us on different topics and amid knockdowns... We learn and sometimes it relieves us....
Let's pray that the covid-19 virus heads to the "less fit" mutation 😁😁😁😁
Yes, but a lot of it was wrong. No disrespect, I was a nurse, but I am also qualified in a lot of fields outside that, and he is clueless, and wrong.

Can not believe I have been watching you for over a year now. How time flies.

Thanks Dr C, you break things down to digestible chunks. I'm still following you after a year and still spreading the Vit D message to all that will lend an ear. I do throw in some of your other gems to mix it up a bit! Thanks for all your time and effort 😘
So well explained Dr John 👍👨🏫 I always learn so much! Love this channel 💕
I realized I will never be as smart as you, but if I keep watching you at least I know I'm not as dumb as those on TV. 😉
What a brilliant way of saying what I’ve been thinking.
I wondered, did I know more now about the blood clot issue than the majority of the Leaders of European Countries🤔
Class comment josie made me laugh best from Glasgow scotland stay safe 👍
Lols. Very true.
👍🏻👏🏻
Your knowledge is amazing. Thank you for sharing it...
Thank you Doctor John. Very informative and a bit scary. We are very blessed to have you to keep us updated. I also have been following your videos for over a year now.
"Let me stick to the viruses otherwise we'll be here forever" this made me laugh! Also, I have a feeling some people wouldn't mind 😂
The only reason God created humans was to provide lounging space for the viruses otherwise they would have no place to live. got it ? Its a housing issue.
The Frankenstein Variant in progress , Ygor ‘s new books on Amazoo’n 📚!
In Short : it Sounds like if We don’t vaccinate the whole world by tomorrow , the vaccinated will become super duper dose carriers !
*HELP !!!*
The top lip was white , the Talk Stilted ! Should I be vaccinated or ... very worried ?
After this talk , probably vaccinated and very very worried 😟!
I certainly wouldn't mind. Dr John makes it all so interesting.
Yeah I don’t, learning some interesting stuff in simple terms
Same 😂😂
Learnt so much this morning next to my coffee, thank you Dr John!
I haven't seen any friends over the last year, but I now consider you a friend, I look forward to your support, common sense and information, i feel i have made a friend and enjoy reading the comments of your other true followers/friends xx
I've been a happy and now informed follower for a few months also, Dr Campbell is a gem🙂
Thanks nicola we are a good bunch here plus we have a bit of wit and humour and we'll educated on this virus so we don't have any fear thanks to Dr John's calm updates best from Glasgow scotland stay safe nicola 👍
Go and watch Uk Column for some even better mates telling you a wjole lot moree home ttuths about your wonderful peoples in authorrity
I only read a few comments as if you delve pretty deep in the comment section you come across the Covidiots trying to push their propaganda and expert advice and 100% these people have absolutely zero medical experience and probably don't work at all... Its pretty mad lol how most people think they can even have views on subjects they don't understand at all like it was funny at first but a year into the pandemic it's growing ever more concerning these people are still pushing the nonsense.
Thank you so much for these videos, been religiously watching you for over a year now.You are a natural teacher to break this down into manageable segments and keep it interesting. Love the tangents and occasional rants along with the English humor.
Funny shaped person? Looks like a well-rounded individual to me. Thanks much for your work!

Well now we know your a layman, so we won't take what you say seriously the next time you make a comment
@@tomjohnson4681 The government ministers who are running this fiasco are basically laymen. They have to rely for advice in people who are supposed to be experts. They then have to make an informed descision based on that advice. Unfortunately not all experts agree and thats where the problem lies.
Thanks Dr John for a very clear explanation of this topic and very pleased to hear from you so early in the day! Good morning everyone and enjoy the weekend.
3:22 I love that the bird flies right by his window as he says: _"All life on Earth being remarkably similar."_
I see and hear you my winged fellow Earthling.
Thank you John for this talk today, very illuminating for me as a retired nurse. The energy you put into keeping us informed is admirable. How privileged are current health care workers to have you as a resource. How fortunate are we to have access to your calm and interesting lectures in a time when there is much disinformation and many people want to create antagonism online. I see the trolls are out in force as your blogs grow ever more popular. This has been a community i have felt honoured to be a part of for the last year, for anyone new on here take the negative comments with a pinch of salt and treat as a measure of John’s success and enjoy the wealth of knowledge available here. Stay safe everyone.
Thank you as always Dr. Campbell. I know this is a serious channel, and the effort you put into your uploads is greatly appreciated sir. Really tired of this current situation, and I want the mutations that lead to people getting super powers!😎
Boot burner, why don't you toddle on over to fox News or somewhere you'll be appreciated. Your harassment won't fly here, we all know Dr. John's background and appreciate his hard work keeping us informed

Good morning John just to say that I really enjoy listening to your talks and follow them daily. I find them easy to follow, well mostly. Yours sicerely Liz
“Remarkably straight forward’ ..... when You explain it 😁 thank you.
Maybe you should read the open letter to the European Medicines Agency. The main author is Dr Sucharit Bhakdi many world renowned scientists as co authors. This human experiment has the potential for complete disaster.
Thank you for the continued education and information, it is much appreciated!
Good Morning Doc and yes i have now been watching you for over a year now and i am happy for that :) Thanks Doc
Dr. Campbell makes me feel less stupid; or ignorant of science. More people should watch these tutorials.
In the end when you mentioned boosters, I was 'whew' from this 😟 to this😲 Thank you again, you deserve the gold medal 🏅 for 'relaying FACTS' during this confusing pandemic!!
Thank you John for giving credit to Alfred Russel Wallace for his independant work on evolution through natural selection and to Charles Darwin for having the grace to acknowledge that they had come to the same conclusions and so agreed to jointly publish their papers on this new and controversal theory.
Maybe Mrs Wallace and Mrs Darwin had something to do with it!
@@jennywren8937 lol
I can just imagine it now:
"Now you two, play nicely together... Stop your arguing and admit that it was a joint effort! Don't you agree Mrs. Wallace?"
"Yes I do Mrs Darwin. Now play nice and go write your acknowledgements. Remember, be pleasent... No snyde, or back handed comments you two... I'm looking at you Charles... Is that clear?"
"Yes dear!"
"Aww... But Charles is always really mean to me and never let's me..."
"What was that? What did Mrs. Darwin and I just say?"
"Nothing... Er?... I meant, yes dear!"
"Good boys!"
😋
@@tmssp Yeah! Sometimes I say "Hey, I've got an idea" and he says "NO!" Would you Adam and Eve it?
Charles Darwin spoke with angels
@@markusmaximus6636 Really? I have another unsourced theory that there was hanky panky between the Wallaces and the Darwins, and someone took screenshots. No, that can' t be right.:))
Thanks Dr John, I’m definitely not a scientific person but I follow all your talks with interest. This one tried to go over my head but that final diagram made it all fall into place. (Just so long as I don’t have to sit any exams☺️)
Think of each of us as a Petri dish. The more Petri dishes exposed to the virus, the more opportunities there are for genetic mutation. If fewer Petri dishes are exposed, there are fewer total viruses in existence, less replication, and therefore fewer mutations will arise. This is how social distancing, mask wearing, and lockdowns prevent mutations-there are fewer Petri dishes exposed to the virus.
For those unwilling to be vaccinated because they “don’t want to be a guinea pig”, they are unfortunately already part of nature’s experiment. They’re volunteering to be a guinea pig in the control group.
@@MarcosElMalo2 through I’ve been suggesting to friends to follow John for verifiable information. Some gave, some I recap info that they will find useful
(Was trying to correct a spelling mistake) some I share the videos. I sadly know of fractured friendships where one side is adamant they are refusing vaccinations. They cannot be talked around but accuse those of us already a vaccinated as being responsible if they do catch it.
As I say there is no reasoning with them and we all make our own choices. My second is due in a few weeks.
Yes, you are perfect sheep!
@@MarcosElMalo2 isolated Petri dishes are far worse than Petri dishes where dominant strains can evolve and spread quickest.
Thanks for your dedication to public health information. I have watched most of your COVID articles so far.
Hi DJ, nice talk on viral biology. Just to be clear, high transmission/infection = higher virulence probability.
In the lab if you want to up viral virulence, you speed up the certainty of viral transmission.
When a virus has certain transmission, virulence goes up - eg, it has no need to worry about killing the host.
So in a viral pandemic it is worth keeping the number of infections down, to slow transmission, in order to lessen the risk of more virulent strains evolving.
What's your opinion on the vaccines?
@@maxmorris4562 As soon as you can get a jab, seize the opportunity. Any vax doesn't matter. The faster the rollout the better.
It's a big subject but I hope that answers your Q.
@@maxmorris4562 My opinion? I hope mine worked. Pfizer-BioNTech.
@@rodwallace6237 No worries. The mRNA vax's are exceptionally good. There's research ongoing to use them for curing cancer and other diseases. They are also the quickest to develop and modify to new strains.
My only downside on vax's is that they should not be over used for young children unless absolutely necessary. Their immune system is developing and different to a teenager/adult. Best to let kids get as dirty as possible, to get their immune system in tip top condition.
Peter A - I completely agree with your second point about children - very wise, and so true. But I can't embrace your first point about the mRNA vaccines, because the jury is still out on those until the the results are in (late 2022). I was reading through Moderna's website, and they refer to their mRNA product development, as an 'operating system' (quote)... able to receive 'Apps' (quote).... and upgrades. Sounds very much like the phone in my pocket, or windows on my PC! Whichever side of the fence individuals are on, regarding GMO, this is certainly a pivotal moment in humanity and our evolution into a new technological era.
Thanks for the update, you do help make some sense of all this. That is to say with an absence of political views.
How is this absent of politics?
@@PravinDahal basically no political view. If you look at the EU and vaccines esp the oxford one.. where they ..lets just say 'poo poo' it. Its not based on science but on a political move to hide the EU's fails on getting this virus vaccine. Its just refreshing to see someone explain the science of it without giving their political view. Major medical institutions like the WHO seem to be governed by Politics NOT science.
@@jobearesto9746 Pharma politics exists and they decide how these agencies operate because they have them by the balls. AZ vaccine did it wrong by making the non-profit pledge, which is biting them on their asses now, because competitors who intend to make enormous profits are willing to invest some more on their PR budget, mostly to stain the much cheaper competition.
The nurse guy here is also held by the balls. Pharmaceuticals will immediately come after his TH-cam channel, his reputation and potentially his pension if he actually addresses this. So, he sidesteps it by saying "it's bizzare, I don't get it" or something to that effect... and keeps himself on their side by spinning everything to be pro-vaccine in general.
I believe that he believes what he says and I don't doubt his honesty... but if he wasn't held by his balls, I'm sure his beliefs would be more aligned with reality.
@@PravinDahal You actually have it somewhat backwards. Oxford originally was going to partner with Merck, a world-leading vaccine producer/distributor (and the originator of the technology Oxford is using). They however chose AstraZeneca who had very little experience instead because of the potential to earn more money in the long run with AZ (reportedly 6% royalties vs 1%). Another reason given was that Merck is an American company while AZ is a British company and they were worried about how that might impact deliveries to the UK. (It’s a shame that the E U wasn’t as wary of that issue).
This is the first video in a long time where Dr. John hasn’t injected his political opinions. Just the science.
John, you are a brilliant teacher! I actually understood that. Huge thank you, keep up the good work.
Great video John, be nice to have guests on to talk about this in greater detail, heard one doctor say what terrifies him is if one of these variants takes hold and then starts hospitalising people in big numbers who have 2 doses of vaccine.
Some people are natural educators and are able to explain complicated subjects in easily assimilated ways that others can't. No prizes for guessing which camp Dr John Campbell falls in to.
He is a fabulous teacher
Thank you for another excellent update!
I wish I had you as an instructor in nursing school way back when. You make complicated issues much more clear. Thanks for all you’re doing!
Brilliant as usual! Thank you so much Dr Campbell

Hi John...nice Saturday morning watching your vid
Yikes! Thank you and please continue your teaching!
Thank you for illustrating and explaining mutations. 👍
He makes complicated things so easy to understand, which is very much appreciated by many.
He forgot the bit about coronavirus hybrid strains. not all mutations are about single letters changes some of them can rewire half the virus through a single host. If two different viruses get sucked through the ribosomes at the same time.
Hi Dr. John, I've been watching your vids since the pandemic started. Awesome vids. Very informative and easy to understand. Thank you so much for all you do.

If I am understanding this, the variants may be an asymptomatic presence in a vaccinated person, who will then transmit this new variant to others. So, even tho we are vaccinated, we are still at risk for contracting the new variants with, perhaps, a milder case. But, more importantly, we can be super spreaders of the new variants???? Is this correct? So my relief at being fully vaccinated and not a significant danger to others....well....that is dashed completely?
Yes and at least one eminent scientist has warned the WHO about the possible dire consequences of that so they can't say they were not warned anf therefore should be held to account!
Mass Vaccination in a Pandemic - Benefits versus Risks: Interview with Geert Vanden Bossche PhD, who is an internationally recognised vaccine developer, virologist,having worked as the head of the Vaccine Development Office at the German Centre for Infection Research. Coordinated Global Alliance for Vaccines and Immunisation’s , He believes he is now morally obligated to put his professional reputation on the line to get this scientific information out to the public, and has sent an open letter to the World Health Organisation highlighting the dangerous principle of mass using of a prophylactic vaccine that does not 100% eliminate infection and transmission in the recipient whist still in the midst of a pandemic which is highly likely to create super vaccine resistant variants in the process .

Dr. Campbell, when this pandemic is over (well, the virus controlled or eradicated anyway), I hope you'll continue doing these videos on other topics in medicine for the general public like this!
Just what I was looking for Thank you
I wish my teachers at school had been able to explain as well as you. I love this science stuff but after a certain point I need it explained rather than reading an ‘age appropriate text book’ and they just couldn’t do it.
At university I had a course called communications. The teacher was awful and could not articulate.
Irony of course she was teaching communications, but couldn't communicate.
Dr John does a good job getting his message across
Thank you so much for this video, great work

For anyone wanting in-depth information on virology, twiv is doing a virology course that explains this in a lot more detail.
Excellent explanation thank you Dr John.
my vision is very bad at the moment (thanks Behcet's!) so I apologize if this is not readable! but my question is are viruses still sort of classified as alive but not? like the categorization of "just alive;" has that stuck or have we discovered more about them?
Has there been any further data in vaccine efficacy in the immunosuppresed? I'm treated with infliximab and azathioprine for ankylosing spondylitis and crohns and due my second dose of AZ on 26th May, with shielding changing at the end of this month that potentially gives 12 weeks between the end of shielding and achieving full efficacy of the AZ. I'd like to know what level of protection I can expect to have but haven't seen any data on that yet myself.

That was brilliant Doc...👍
Good stuff.
When you feel better (get well soon!) can you do a video about all of the new virus variants that we know about (UK/B117, S.Africa, Brazil, I think there's a couple US variants now)?
Fantastic John - thankyou for the explanation.
How is being infectious before signs and symptoms show, unique? Isn't something like chickenpox (or similar or well known something) most contagious before signs and symptoms show?
It's a coronavirus.. chickenpox etc aren't
Love you Dr. John. You are a rockstar. I go to bed every night listening to your voice. You are the Edward R. Murrow of this modern day war. You deserve some reward when this is over for your perseverance and tenacity for keeping us informed.
Definitely. Perhaps an emmy to a *truly deserving* person.
Thank you for being such a good teacher. How likely do you think is that we can create new versions of vaccines to tackle the new variants in time?
I think we are always going to be just trailing the mutations.
Is it not the case that most mutations are silent? For those interested, this is where a change in the base either doesn't change the amino acid corresponding to the codon (triplet of bases) or the new amino acid does not change the structure of the protein enough to affect it in any way.
Thank you dr John - this virus makes every day a school day! Your input is so much appreciated 😷

Wonderful lesson on mutation, can’t wait to show this to my 15 yr old granddaughter, perfect timing for her biology studies.
This virus is not only spread at the pre symptomatic stage, so the effect of becoming more mild is only reduced not eliminated. If symptomatic people can't spread the virus then nurses wouldn't need any PPE now would they?
Yes! Cristalclear explanation! Thanks.
Except the bit about covid presymptomatic transmission in the middle of the video.
Shorter and shorter incubation, would have an evolutionary advantage, unless we had a ludacris lockdown.
