So far Delta is winning against all the other variants.

Even Alpha, Beta and Gamma - and the other "variants of interest" up to Mu and new ones like C.1.2 that they are keeping an eye on.

Seems Delta is pretty hard to beat.
Many people don't realize - unlike antibiotics - it is very unusual for a virus to evade vaccines at all. Only flu does it every year.

In these videos I'm commenting on my previous tweet thread here:

Interesting situation, Novavax is first vaccine sent to WHO for approval first - stronger economies saturated in vaccines, so, much less interest in developing new vaccines.

Novavax also very good at transfer of technology and first deliver of 100 million doses is to COVAX.
Example, Hexapro tweak, in clinical trials by weaker economies, licensed by Texas University, likely better than the 2P tweak used by Pfizer / Moderna.

Expect more vaccines like this in 2022, better vaccines, easier to grow, and more effective, may go to weaker economies first.
Weak economies can vaccinate very fast - US, UK, EU etc were very slow because we are not used to vaccinating large numbers of adults + supply issues.

Bhutan vaccinated the same % as Israel in only 11 days and Brazil in 1990 vaccinated every child against polio in a single day.
Yes we will have enough vaccines to vaccinate the world in 2022. If it is needed we could have 10 billion+ doses every 3 months in 2022 (later in the year)

So we will have the capacity.
We don't have to "live with COVID" with thousands of people dying a year.
Flu is ONLY remaining hyperendemic disease
- polio, and smallpox were hyperendemic in the past and are all gone or almost gone.
WHO say we can keep COVID very low like measles
- false anlaogy with flu.
Why we need to keep transmission low to stop variants.

Every time you block a chain of transmission by being careful you are doing your part to stop new variants - you never know - the chain of transmission you blocked could have evolved to the next variant of concern!
How to protect yourself. In many places e.g. in Scotland your risk is the highest it has been for the entire pandemic - no matter what other people tell you - especially if unvaccinated.

So - be aware of your local situation and take care.
To summarize, things look very positive for this time next year - by this time next year may already be starting to move into the history books. Meanwhile take great care!

There are many things you can do to help block transmission.

Each chain of transmission you break may save lives, hospitalization, long COVID, even a new variant that could have evolved from it - you will never know what you stopped :).

@DocLT2 Yes indeed. Many reinfections already, some within a few weeks. bnonews.com/index.php/2020…
Coronaviruses often reinfect. This shows infections of one individual by 4 coronaviruses from blood sample antibodies. Each black dot = inferred infection. nature.com/articles/s4159…

@DocLT2 This is steady state after centuries to 1000 years evolution without vaccines.

With COVID it's only just leapt to humans.

This was written just before alpha was detected. In last sentence, didn't expect variants to evade immunity so soon with COVID.

@DocLT2 It's very limited data for coronavirus colds - they surely are just as complex as COVID and more so but we barely see the tip of the iceberg of the complexity.

This is some of the complex history that they knew so far as of 2006. ncbi.nlm.nih.gov/pmc/articles/P…

IPCC report here, very clear. Have a read of the summary for policy makers near the start of the repot.

ipcc.ch/report/ar6/wg1…

IPCC press briefing again very clearly presented.
The other material is here: ipcc.ch/report/ar6/wg1 - the download link for summary for policy makers doesn't work which is why I linked to the full report. ipcc.ch/report/ar6/wg1…
These are the four scenarios they look at.
SSP1-1.9: Zero emissions for 2050+, ~1.4 °C long term
SSP1-2.6: Zero for 2070+, ~1.8 °C
SSP2-4.5: Low emissions by 2100, ~2.9 °C
SSP2-7.0: Double emissions by 2100, ~3.6 °C
SSP2-8.6: Double emissions by 2050, ~4.4 °C

Westminster gov. failed to bring the virus under control & is now preparing to remove the last few remaining measures that inhibit it from spreading even more widely amongst our only partially vaccinated population.

International COVID experts respond:
Almost 50,000 cases per day
Only half fully vaccinated.
Expect many millions infected over summer.
UK gov. has chosen to do this even though we have effective vaccines.

We ask experts to respond
New Zealand: Always looked to UK for leadership

Remarkable depth of scientific knowledge.

Remarkable clinical trials we are drawing on.

Incredible development of vaccines & rollout.

Astounded you are doing this despite amazing expertise you have in UK.

Headlines about solar storm headed for Earth are fake news. There was an X-class flare that caused some over the horizon radio blackouts on July 3 - few people use long wave radio now.

Tony Rice from NASA explains here:

wral.com/no-there-isn-t…
Solar flares and solar storms do nothing to the internet (connected via optical fibre) or cell phones (connected via direct microwave transmission). They can cause short term glitches in GPS.
Once per century solar storms may cause powercuts, in particular places depending on local geology and lengths of power lines, indistinguishable from ones we get anyway - surges could affect old model step up down transformers or near end of their life.

The BBC tell us
1. exit wave is inevitable - FALSE
2. COVID is seasonal - during huge summer surge!
4. opening up now relieves pressure on the NHS in winter -higher estimates for summer hospitalization surge similar to H1N1 peak!

A mass of logical absurdities.
We are 50% unvaccinated. We need to finish that vaccination and also vaccinate down to adolescents - that's an extra 2 days for each year group at 400,000 doses a day. That gives far better immunity than natural infection and we are better prepared for the winter.
That's 2 days per age group for first dose then the same again 3 weeks later. Then we have masks, test trace isolate, physical distancing, ventilation, #DOITALL in ways that have no impact on economy as we open up carefully. Meanwhile by autumn we have vaccines that target delta.

This is to help people who think the 4.9 C path or "business as usual" is still possible. Quotes a tweet from @Peters_Glen from 2019. Situation is the same today in 2021 and even more so.

debunkingdoomsday.quora.com/Why-the-busine…
His twitter thread discussing the 4.9 C path (RCP 8.5) is here


I refer to it as the 4.9 C path just because not many people know what RCP 8.5 means but that's technically more accurate, really a scenario of CO2 emissions with a narrative to motivate it.
The Paris Agreement is working. Carbon Action Tracker had this projection for 2100 in December 2018 just after the report on the difference between 1.5 and 2 C
