Since Vaccination efforts in areas experiencing a rapid increase in new coronavirus disease (COVID-19) cases will be ramped up so they can immediately achieve herd immunity, the National Task Force (NTF) Against COVID-19 bared Tuesday, April 6. We're still weeks or months away from the general public being able to get the COVID-19 vaccine. How fast we get to that point will depend on how quickly vaccines are How many people in a population will need to get a COVID-19 vaccine before herd immunity is achieved? This question has been all over the news lately, with speculations of 70%, 80%, or other numbers.

Another new study takes a different approach to estimating differences in susceptibility to COVID-19 and puts the herd immunity threshold even lower. is nowhere near that point with SARS-CoV-2, and getting there could prove difficult What is that COVID-19 estimate based on?
