JAMA Network Open has published a new study showing that, from April 1, 2020, to February 27, 2023, in California, an estimated 146,210 COVID-19 cases were averted by vaccination in teens aged 12 to 15 years, representing a 37% reduction.
There is no way to predict if the virus will acquire the capacity to spread between people, or when and under what conditions it would make that fateful leap if it does.
Amidst the anticipated increase in vaccine-preventable diseases as the global population ages, a first-of-its-kind study has underscored the dual benefits of adult immunization programs.
A new study coming out of York University's Centre for Disease Modelling in the Faculty of Science shows that immunity after a COVID-19 booster lasts much longer than the primary series alone. These findings are among other—sometimes "unintuitive"—revelations of how factors like age, sex and comorbidities do and don't affect immune response.
The work is published in the journal Scientific Reports.
Independent reviewers confirmed a causal relationship between the first mRNA COVID-19 vaccines and myocarditis, and also determined that, more broadly, intramuscular shots can cause a series of shoulder injuries.
Smallpox, a disease that killed an estimated 500 million people in the 20th century alone, is the only human disease to be eradicated. However, a new report, "Future State of Smallpox Medical Countermeasures," from the National Academies of Science, Engineering, and Medicine (NASEM) argues that the U.S. and the global community should prepare for smallpox to make a return.
the analysis shows that the risk of sudden death in young adults after being vaccinated is significantly lower than the risk of sudden cardiac death from all causes — about 1 in 500,000 per year, compared to 1 in 100,000 per year, according to his estimates.
