Because I am an avid traveler and I’m going to have to get it if I want to keep traveling again. Many countries are going to make it a requirement to get in
It's not just global travelers that will need a vaccination. Hundreds of universities and colleges are requiring the vaccine to enter this fall. A broad majority of U.S. employers, 65%, plan to offer employees incentives to get
vaccinated and 63% will
require proof of
vaccination. Although the current trajectory of vaccinations will dramatically reduce infections, the virus will continue to kill hundred or thousands a year in the US. Today over half the population has had at least one dose. We need to get that figure to over 70%. Then we approach herd immunity and virus will die out in the US. The major threat will then be a new more dangerous variant from broad. Thankfully RNA vaccines can easily be adapted for new variants.
Wow, sounds like the CDC/Biden recording. On what SCIENCE are you basing your bullshit projections on?
It's not science. It's math.
The only thing you need to know to calculate herd immunity is how many people, on average, are infected by each infected person. This value is called R0 (pronounced “R naught”). Once you have that, you can plug it into a simple
formula for calculating the herd immunity threshold: 1 − 1/R0. Unfortunately it takes a lot of data to determine Ro and what you end up with is a range. That range leads to a value between 70% and 80% immunity to reach herd immunity.
Let’s say the R0 for COVID-19 is 2.5, meaning each infected person infects, on average, two and a half other people (a common estimate). In that case, the herd immunity threshold for COVID-19 is 0.6, or 60%. That means the virus will spread at an accelerating rate until, on average across different places, 60% of the population becomes immune.
Daniel Arlein has already had COVID-19. In March, the 36-year-old small business owner and DJ, who lives in Brooklyn, tested positive for the viral infection an…
