While it found that global uptake of at least one COVID-19 vaccine dose was robust, a new survey published in Nature Medicine revealed mixed signals about the current acceptance of vaccines generally, especially COVID-19 boosters. ...
"The repercussions of pandemic disruptions in health care services, the effects of the inequitable and slow global vaccine distribution, and the prevalence of misinformation and mistrust in health authorities continue to be felt," says Jeffrey V. Lazarus, Professor of Global Health at CUNY SPH, head of the Health Systems Research Group at Barcelona Institute for Global Health, and coordinator of the study.
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.
