Key TakeawaysIn rare cases, Pfizer’s and Moderna’s COVID-19 vaccines have triggered myocarditis, or heart inflammation, typically in males under 30. Most reported cases have been mild and people have recovered from the condition.The FDA will update the COVID-19 vaccine fact sheets to include a warning about risk of heart inflammation.The CDC’s vaccine advisers said the benefits of COVID-19 vaccinations still far outweigh the risks. Key Takeaways In rare cases, Pfizer’s and Moderna’s COVID-19 vaccines have triggered myocarditis, or heart inflammation, typically in males under 30....

Key TakeawaysResearch shows that a third COVID-19 vaccine dose may increase antibody levels in solid organ transplant recipients.Transplant recipients often take medications that suppress their immune systems to prevent organ rejection, which leads to a suboptimal antibody response.Further research is necessary to see if an increase in antibody levels indicates better immunity against COVID-19. Key Takeaways Research shows that a third COVID-19 vaccine dose may increase antibody levels in solid organ transplant recipients....

Key TakeawaysTwo researchers released an article outlining the information doctors can pull from when discussing the risks and benefits of the COVID-19 vaccine with pregnant patients.The results of studies show that both mothers and babies benefit from vaccination against other respiratory diseases such as influenza and pertussis.Recent research suggests that pregnant and lactating women are more likely to have adverse health and pregnancy outcomes if hospitalized with COVID-19 owing to the respiratory impact of physiological changes associated with pregnancy....

As of June 1, 2021, 41% of Americans are fully vaccinated against COVID-19, including over half of all adults. Biden’s July 4 Goal70% of U.S. adults will have at least one shot160 million U.S. adults will be fully vaccinatedAs of June 162.8% of U.S. adults have at least one shot134 million U.S. adults are fully vaccinated Biden’s July 4 Goal70% of U.S. adults will have at least one shot160 million U....

This progress is partly the result of steady federal improvement. The government delivered 30 million vaccines to the states this past week, a slight increase from the week prior. Roughly 3.2 million vaccines are being administered per day, meaning that 80% of available vaccines are making it into arms for the second week in a row. Almost a quarter of the U.S. population is fully vaccinated against COVID-19. Progress In Spite of a J&J Fumble The strong forecast for state-level supply comes at a time when one of the three vaccine brands available to Americans has hit a series of setbacks....

Even while the Johnson & Johnson vaccineremains pauseddue to an investigation surrounding rare and severe side effects, COVID-19 vaccination rates are holding steady in the United States. As of April 20, over a quarter of the U.S. population is fully immunized against COVID-19, and 40% have received at least one dose. Eighty percent of available vaccines are making it into arms for the third week in a row—a high level of efficiency compared to the 50% rate we observed when this tracker launched in January....

While this is a significant achievement, the milestone comes alongside some troubling vaccination trends. AsThe New York Timesreported earlier this week, CDC data shows that about 8% of recipients of a first Pfizer or Moderna dose failed to return for their second shot. This adds up to over 5 million people. The last time the CDC released a report on second dose completion, on March 19, only 4.4% of Pfizer and Moderna recipients failed to get the second shot within the recommended time frame....

The United States is now vaccinating over 3 million people against COVID-19 every day. And Friday, April 2, brought a new milestone: 4 million doses were reportedly administered. For the first time since Verywell started this tracker, the country is using over 80% of the doses available—the most efficient rate we’ve seen yet. Nearly 19% of the population is fully immunized, and over 32% has received at least one COVID-19 vaccine....

While the United States is inching forward in its COVID-19 vaccine distribution to the states, the states are getting a better handle on administering those vaccines to their citizens. This time last week, only half of the vaccines allocated federally had actually made it into arms—a process which falls largely to each state. But as of February 2, 64.5% of available shots have been administered. Currently, the Food and Drug Administration (FDA) has authorized vaccines from Pfizer-BioNTech and Moderna for emergency use in the United States....

As of today, the Centers for Disease Control and Prevention (CDC) says 71,657,975 vaccine doses have been shipped to states. But we may see a sharper increase in the coming weeks. On February 16, the Biden administration announced it will increase the number of COVID-19 vaccine doses going to the states from 10 million to 13.5 million per week. Vaccination Sites Are Becoming Easier to Access While we wait for those extra doses, we can already monitor the impact of some other recent federal initiatives to boost vaccine availability across states....

While the country might not be feeling the immediate impact just yet, COVID-19 vaccination efforts improved significantly in the U.S. last week. Why 70%?While there’s still no clear percentage of the population necessary to reach herd immunity for COVID-19, 70% is a good place to start. Herd immunity refers to the protectiveness achieved when a significant portion of a population develops immunity to an infectious disease, either through vaccination or having a prior illness....

Comparatively, during the last week of January, only about half of vaccines delivered federally had actually been administered. Currently, the Food and Drug Administration (FDA) has authorized vaccines from Pfizer-BioNTech and Moderna for emergency use in the United States. Each vaccine requires two doses for COVID-19 immunity, spaced 21 days (Pfizer-BioNTech) or 28 days (Moderna) apart. While the improvement in vaccination efficiency is a step in the right direction, it’s not a massive change....
