How a Covid-19 Vaccine Will Be Distributed
Once a vaccine is made, it still needs to get to enough people
How to get a coronavirus vaccine to millions of people. Developing a successful vaccine is step one, but making sure everyone has access is another major undertaking. As Emily Mullin reports for OneZero, if or when a vaccine becomes available, governments will need to prioritize who gets it.
A huge number of people will need to receive a vaccine in order to stop the spread of the coronavirus and establish herd immunity — the point at which most of the population is protected against an infectious disease. To achieve herd immunity against Covid-19, anywhere from 50% to 90% of the population may need to be immune. And, since no vaccine is 100% effective, the more people who are vaccinated, the better. Getting a vaccine to all the people who need one will take a massive effort, both in the United States and around the world. There has never been a global immunization campaign on the scale that will be needed to distribute a Covid-19 vaccine.
