NEW YORK, NY — Global willingness to accept a COVID-19 vaccine increased from 75.2 percent in 2021 to 79.1 percent in 2022, according to a new survey of 23 countries that represent more than 60 percent 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 new study finds that testing for a single immune system molecule on nasal swabs can help detect stealthy viruses As the COVID-19 pandemic showed, potentially dangerous new viruses can begin to spread in the population well before the global public health surveillance system can detect them. However, Yale researchers have found that testing for the presence of a [...]

Findings show increased mortality risks in offspring from birth to young adulthood A disorder that can trigger abnormally high blood pressure in pregnancy is associated with increased risks of death in offspring from birth to young adulthood, finds a study published by The BMJ. The findings, based on data from over two million individuals in Denmark, show increased risks of [...]

Rapid, sensitive sepsis diagnosis can now be performed with biphasic amplification in a dried blood matrix Bloodstream infections (BSIs) and sepsis result in high morbidity and mortality, particularly in critically ill patients and neonates. Patient outcomes can be significantly improved by administering antibiotics within three hours of initial symptoms, but current diagnostic methods take much longer to diagnose BSIs/sepsis. [...]

Rotary evaporator, also known as rotary evaporator, is mainly a common laboratory equipment composed of motors, distillation bottles, heating pots, condenser tubes and other parts. The development history of rotary evaporator 1. Wool condenser Ancient Greek sailors noticed fog condensation droplets on the sails, and sailors placed wool over heated jars to obtain fresh water, which was later known [...]

Since SARS-CoV-2 first appeared in December 2019, scientists around the world have been racing to find out more about the novel coronavirus. While the virus has claimed almost four million lives, new developments in COVID-19 research have offered hope to pandemic-stricken countries around the world. Below, we spotlight some of the most exciting new developments and answer some key questions [...]

Types of COVID-19 Vaccines At present, there are 5 routes to develop COVID-19 vaccines. In addition to adenovirus vector vaccines and inactivated vaccines that have entered clinical trials, vaccines of the other three technical routes are also entering clinical trials. What are the characteristics of these 5 vaccines? 1. Inactivated vaccine Inactivated vaccines are the most traditional and classic technical [...]
