COVID-19 vaccine acceptance increased globally in 2022

Global willingness to accept a COVID-19 vaccine increased from 75.2% in 2021 to 79.1% in 2022, according to a new survey of 23 countries that represent more than 60% of the world’s population, published today in Nature Medicine. Vaccine acceptance decreased in eight countries however, and nearly one in eight vaccinated respondents were hesitant about receiving a booster dose. This third annual study, […]

New COVID-19 rapid-test technology performs PCR faster than similar tests on the market

For more than 30 years, polymerase chain reaction (PCR) has been the gold standard in molecular diagnostic testing, detecting genetic material, such as those from a virus or from human DNA. But PCR, including reverse transcription polymerase chain reaction (RT-PCR), is mostly done at large, centralized laboratories, not in point-of-care (POC) settings, because its instrumentation is bulky, expensive, takes a […]

COVID-19 vaccination does not appear to raise stroke or heart attack risk for patients with cardiovascular disease

Vaccination for COVID-19 does not appear to increase the risk of heart attack or stroke in patients with established cardiovascular disease, researchers reported on June 23, 2022 in Cardiovascular Research. “Our study showed that pre-existing cardiovascular disease should not prevent people from getting vaccinated against COVID-19,” said study author Dr. Esther W. Chan of the Li Ka Shing Faculty of Medicine, […]

Why COVID vaccines are deemed non-essential for UK young children

Throughout the pandemic the University of Huddersfield’s Department of Pharmacy has been raising awareness on what vaccines are, how they are formulated, and why they’re an important part of the healthcare strategy as well as the progress on further developments in COVID vaccines, so that people can make an educated decision on becoming vaccinated or if choosing for their children. In […]

Long COVID poses risks to vaccinated people, too

Even vaccinated people with mild breakthrough COVID-19 infections can experience debilitating, lingering symptoms that affect the heart, brain, lungs and other parts of the body, according to new research from Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care System. The study of more than 13 million veterans also found that vaccination against […]

Conventional vaccine messages miss the mark

Promotional campaigns designed to increase vaccine uptake are often ineffective, according to a new study in eight European countries. Some initiatives which highlight the benefits of immunisation may even be counterproductive, say scientists. Researchers at the Technical University of Munich worked with colleagues at the University of Trento and the London School of Economics and Political Science to test the […]

Researchers roll out data on COVID vaccine distribution and waste

Researchers are rolling out a data set that provides detailed information on COVID-19 vaccine shipments and wastage across the United States, with the goal of spurring new data analysis to improve vaccination efforts in the future. The work stems from a collaboration between researchers at North Carolina State University and BuzzFeed News. “The development and distribution of COVID-19 vaccines has […]

Harnessing vaccine technology to heal bone

Although fractures normally heal, bone will not regenerate under several circumstances. When bone does not regenerate, major clinical problems could result, including amputation. To enhance the regeneration of bone, the Food and Drug Administration (FDA) approved recombinant human bone morphogenetic protein-2, or BMP-2. However, it is expensive and only moderately effective. It also produces side effects ? some severe. Researchers […]

Antibodies improve in quality for months after COVID-19 vaccination

For at least six months after COVID-19 vaccination, antibodies produced by immune cells become steadily more formidable and more precisely targeted against the virus that causes COVID-19, according to a study of the antibody response to the Pfizer-BioNTech vaccine by researchers at Washington University School of Medicine in St. Louis. The idea that antibodies increase in quality as they decrease […]

Possibility of vaccine to prevent skin cancer

Research by the Oregon State University College of Pharmacy suggests that a vaccine stimulating production of a protein critical to the skin’s antioxidant network could help people bolster their defenses against skin cancer. Ultraviolet radiation from the sun leads to oxidative stress, which increases the risk of skin cancers such as melanoma, explains Arup Indra, professor of pharmaceutical sciences at […]
