A new study from American Journal of Preventive Medicine, published by Elsevier, used a computational model to find that a COVID-19 vaccine with at least 80% effectiveness would lead to a “return to normal.”
- The study said if 75% of people get the vaccine, it has to have an efficacy of at least 70% to prevent an epidemic.
- If it reaches 80%, then the current pandemic would be eliminated completely.
The study said the thresholds climb with less people who get vaccinated.
If 60% get the vaccine, then we would need an 80% effective rate to stop an epidemic and a 100% success rate to end the pandemic.
“Some are pushing for a vaccine to come out as quickly as possible so that life can ‘return to normal.’ However, we have to set appropriate expectations. Just because a vaccine comes out doesn’t mean you can go back to life as it was before the pandemic. It is important to remember that a vaccine is like many other products — what matters is not just that a product is available, but also how effective it is.” — lead investigator Bruce Y. Lee said in a statement.
