I built the coronavirus forecasting dashboard which makes predictions for covid cases/deaths for all countries and US states. In this post, I will explore the remarkable similarity of covid infection waves across many areas of the world.

More than 99.9% of the Pfizer Vaccine Placebo Group did not get a severe case of covid

covid vaccine Nov 28, 2020

The Pfizer vaccine trial has 43,000 participants. Exact breakdown between treatment and placebo groups is not given, but they do provide the number of covid cases in each group. Currently, there are 162 covid cases in the placebo group.

Assuming a 50/50 split, 99.25% of the placebo group did not get covid.

Additionally, only 9 in the placebo group had a "severe case" and no one died. That is 99.96% in the placebo group did not have a severe case.


We need to know the overall...

import matplotlib.pyplot as plt import numpy as np x = np.arange(-2, 8, .1) y = .1 * x ** 3 - x ** 2 + 3 * x + 2 fig, ax...
