"That’s what viruses do, they evolve, but we can prevent the emergence of variants by preventing transmission. It’s quite simple. More transmission, more variants. Less transmission, less variants."

There are billions of vaccine doses coming along later this year. Biden says he will give excess doses to other countries, so the US is expected to be a huge donor later this year. Even if the US fully vaccinates everyone, adults and children, twice over, now and in the fall, the US has secured so many doses for 2021 that it will be able to fully vaccinate 1.3 billion people outside the US as well.

We have major bottlenecks with producing the vaccines, but the WHO say that it doesn't have to be like this. We already have millions of extra doses of COVID today because of the early technology transfer by AstraZenecs at the end of last year. This empowers the rest of the world to make the doses, which greatly increases vaccine supply and helps to end the pandemic fast. Novavax is also in the process of transferring technology in the same way, ready for when it gets approved. However most vaccine manufacturers are not doing this and as a result we are missing out on many millions of doses the world could have if they did facilitate technology transfer.

The US has enough doses to vaccinate its entire population twice over and have enough left to fully vaccinate 1.3 billion people outside the USA by the end of 2021. It's not going to run out of doses. As most of you will know, Biden has committed now to roll out 200 million doses to the USA in his first 100 days in office. The USA is making huge steps forward with its own population.

We have major bottlenecks with producing the vaccines, but the WHO say that it doesn't have to be like this. There are many companies that could have produced them if they had been authorized to do so. There are things we can do to ease the bottlenecks right now and we could hugely increase vaccine production capacity a few months from now through technology transfer.

I base this on the advice of the WHO, the US CDC and other such reliable sources.

1. Most people don’t know to isolate from their own household and that you can still protect your loved ones if you develop symptoms of COVID.

You may remember this video of how Li Ting, an emergency room nurse looked after his wife at home in Wuhan.
