Explore Vaccination Progress by U.S. State
With dozens of COVID-19 vaccines now in clinical trials, it is important to understand the accelerated timelines for development, the different types of vaccines available, and the facts related to vaccine safety and efficacy. Additionally, as vaccines are approved, we will track data on vaccination efforts.
Explore how U.S. states delivered their supplies of COVID-19 vaccines to their residents at vastly different speeds that led to vastly different results.
An interactive tool from our vaccine experts that explores how a vaccine is developed and the differences between a typical timeline and an accelerated timeline.
VIEW-hub is a publicly available interactive tool that displays up-to-date information on vaccine characteristics, and vaccine introduction and use globally. Vaccines include COVID-19 as well as many childhood vaccines in routine immunization programs.
SARS-CoV-2, like all viruses, is constantly mutating – a process that has spawned 11 different named variants of the virus during the pandemic so far. The fastest spreading of those has been Delta, a much more transmissible variant that is thriving in a world where only about 13% of the international population had been vaccinated by mid-July.
As the Delta virus variant continues to spread, experts have been discussing the possible need for booster doses for those who have been vaccinated. Pfizer is now seeking emergency use authorization from U.S. regulators to distribute a booster shot developed for its COVID-19 vaccine.
Declaring success regarding the commonly misunderstood concept is not as simple as the public believes.
This series of brief reports will shed light on COVID-19 vaccine development, allocation and deployment in the United States and globally. Topics will include ensuring the safety and efficacy of Covid-19 vaccines, principles for vaccine allocation, strategies for deployment and delivery of Covid-19 vaccines, vaccine confidence and demand, and the economics of Covid-19 vaccines.
COVID-19 VACCINE MATTERS: A blog series discussing the evolving science and policy of COVID-19 vaccines, led by internationally renowned experts in vaccine development, Dr. Larry Corey of the Univeristy of Washington, and Dr. Chris Beyrer of Johns Hopkins University.
Johns Hopkins University and the University of Washington hosted a high-level symposium, “The Scientific Integrity of COVID-19 Vaccine Efficacy Trials: From Clinical Trials to Public Allocation,” that explored complex issues, brought together leading voices in the field, and put forward a concise plan for protecting the scientific integrity of these ongoing efforts.
If you do end up getting sick despite vaccination, experts say the shots are very good at reducing the severity of the illness — the main reason to get vaccinated.
As debates abound over whether coronavirus vaccinations should be required in public schools, many experts point out that students already are required to receive several other routine vaccinations to attend childcare or classes in the United States.
Johns Hopkins Center for Health Security Senior Scholar Jennifer Nuzzo discusses travel restrictions on fully vaccinated individuals.
As wealthy nations with high vaccination rates like the U.S. begin emerging from the pandemic, the disease is accelerating in parts of the world.
Johns Hopkins International Vaccine Access Center Executive Director Dr. William Moss talks about the effectiveness of Covid vaccines against variants.
Although there is plenty of supply of the authorized vaccines in the country, approving the use of additional vaccines can make it easier for people to get vaccinated.
While more information is needed to decide whether people might need booster doses, a future rise in breakthrough cases might offer us clues.
The largest U.S. database for detecting events that might be vaccine side-effects is being used by activists to spread disinformation about COVID-19 vaccines.
One-third of unvaccinated U.S. adults say they will only get in line for the COVID-19 jab once it's fully approved, but medical experts say it can also be risky to wait.
