The world has come together and made extraordinary scientific achievements in the fight against the coronavirus pandemic. It's now time for unprecedented industrial collaboration to rapidly increase Covid-19 vaccine manufacturing capacity. Production of mRNA/DNA vaccines needs to be increased by 6.8 billion doses by the end of this year - in several locations across the world.

Our previous thought piece delved into the question of how many doses of Covid-19 vaccines are needed to protect front-line health workers and people at higher risk of severe or critical Covid-19 disease. We knew at that point we were leaving out all other essential workers and received several queries on what that number could be.

The race for Covid-19 vaccines is well underway. As is the thinking on how to allocate what will be a limited supply for the first many years of production. This thought piece looks at how many doses of Covid-19 are needed to protect people at risk of severe or critical Covid-19 disease and front-line health workers.

During these Covid-19 times, the Yellow House is sourcing most of our pandemic information directly from experts and data sources online. We can read it when we want to and with our own tone. Here is our current list of sources for the figures, modeling the future transmission curve, the top experts, as well as good news.

The world is in the midst of a defining moment. Last week marked 100 days since WHO confirmed the first case of Covid-19 and 6 weeks since a global pandemic was declared. In a short period of time, a massive amount of change has been thrust upon us as the SARS-CoV-2 virus makes its way around the world. What's here to stay, and what will continue to change? What could society look like after 1000 days?
