Covid

Methodology

The data presented here comes from a team led by Marta Galanti and Jeffrey Shaman at Columbia University in collaboration with researchers at Pfizer.

The model assumes a vaccine efficacy of 90 percent 10 days after the first dose and 95 percent one week after the second dose — and that those vaccinated will ultimately receive both doses. The model also assumes a vaccination schedule following the C.D.C. guidelines for different groups, followed by a distribution ramping up to five million doses per week of other adults and children.

Historical case data is used to estimate the number of past infections and effective reproduction rate in each state as of Jan. 10, 2021. Infection projections are based on the virus having a basic reproduction number of 2.4 without any nonpharmaceutical interventions, including social distancing restrictions.

In each scenario, restrictions are fully relaxed at the date indicated, except those in which restrictions are strengthened. In these scenarios, restrictions are gradually relaxed over the following months. For scenarios in which restrictions are strengthened, the basic reproduction number is lowered to 1.5.

Me: You cannot catch Covid, you have to catch Coronavirus first and wait 10-14 days for it to become Covid. Nobody is treating Coronavirus, so that it does not become Covid, because there is no money to be made from doing that and the rich won’t get paid any money making vaccines which might not work with later Covid pandemics, when the existing vaccines no longer work. Bit like the Fox chasing its tail. It never catches its tail, but that does not stop it trying to.
