In this Axios column, Drew Altman says full FDA approval of COVID-19 vaccines can provide a big boost to vaccination efforts if treated as an opportunity for updated messaging from government officials at all levels and public health experts and new actions from employers.
This Vaccine Monitor report finds little change since June in the share of adults who either received a COVID-19 vaccine or say they will as soon as they can. A quarter of unvaccinated adults say they likely will get a shot by the end of the year. Unvaccinated adults are much less worried than vaccinated ones about the Delta variant.
This fact sheet reviews what employers can and cannot do under current rules and guidance to require or encourage their workers to get vaccinated against COVID-19.
Early in the COVID-19 pandemic, residents and staff at nursing homes and other long-term care facilities accounted for a huge share of COVID deaths, but a new KFF analysis finds that they were relatively rare events across the country in June.
This data note examines state-level data on COVID-19 cases and deaths in long-term care facilities through June prior to the recent rise in cases and deaths nationally linked to the spread of the Delta variant. It finds long-term care deaths down 96% from their peak in December as the nation's vaccination effort began.
As COVID-19 cases increase along with spread of the more transmissible Delta variant, the effectiveness of COVID-19 vaccines continues to be an important topic.
We reviewed the websites and other official state sources for all 50 states and D.C. to see which are providing data on COVID-19 breakthrough cases, hospitalizations and deaths, how regularly, and what those data may tell us.
Analysis of characteristics of children under 12 in the U.S. to help inform COVID-19 vaccination efforts when they become eligible.
This analysis looks at global COVID-19 vaccination efforts by income-level and region to assess the equity gap in both vaccination coverage and rates of administration. Overall, we find that low-income countries and countries are lagging behind, and based on current rates, are unlikely to meet global vaccination targets.
A new KFF analysis finds that only 1% of those in low-income countries have received at least one vaccine dose compared to 51% in high-income countries, highlighting the substantial vaccine inequities around the world. The analysis examines these inequities by country income level and by region, finding large differences for each.
