Paragraph: All bars in Belgium have been shut since the start of the lockdown a month ago, dealing a blow to smaller brewers such as Brasserie de la Senne, en Stoemelings or La Source Beer, whose products are hard to find in supermarkets, which remain open. To keep business alive, half a dozen of the microbreweries are encouraging their fans to buy online, charging around 50 euros for a case of 24 bottles, bicycle delivery included. Some even offer to donate up to 30 euros or a percentage of such direct beer sales to Brussels hospitals to help fight the pandemic. More than 5,500 people are currently in Belgium’s hospitals with COVID-19, the disease casued by the virus. Jeroen Verhoeven, 42, who runs the Bicy KLET beer delivery  service for Brasserie de la Senne, said he has been in business since 2013, but that during the lockdown volumes have soared and he sometimes has to ask friends to help, to meet all the demand. Before the lockdown he would deliver about 40 cases a month but now he is delivering that number in just one day, he said. “It is now really taking off, I sometimes deliver 40 cases a day,” he told Reuters. As soon as he gets money in his account, he hops on the bike and delivers the beer, depositing the crate on the doorstep to avoid direct contact with the buyer. “It is nicer now in the lockdown because there is far less traffic in the streets,” Verhoeven said. Claim: Yearning for a pint? Brussels brewers deliver to homes during coronavirus lockdown.
With beer sales hit by the coronavirus lockdown, small Brussels breweries are offering a delivery service to the homes of thirsty customers and for some business is booming.

Paragraph: Researchers around the world are working to develop potential treatments or vaccines against the respiratory disease that has killed nearly 47,000 people and infected almost a million in just a few months. A team at the University of Pittsburgh School of Medicine in the United States said they were able to move quickly in developing a potential COVID-19 vaccine after working on other coronaviruses that cause Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). “These two viruses, which are closely related to SARS-CoV-2 (the new coronavirus causing the COVID-19 pandemic), teach us that a particular protein, called a spike protein, is important for inducing immunity against the virus,” said Andrea Gambotto, an associate professor at Pittsburgh. “We knew exactly where to fight this new virus.”  When tested in mice, the prototype vaccine - which the researchers have called PittCoVacc - generated what they described as “a surge of antibodies” against the new coronavirus  within two weeks. The Pittsburgh researchers cautioned that because the animals have not been tracked for very long as yet, it is too early to say whether and for how long the immune response against COVID-19 lasts. But they said that in comparable tests in mice with their MERS experimental vaccine, a sufficient level of antibodies was produced to neutralize the virus for at least a year. So far, the antibody levels of the SARS-CoV-2 vaccinated animals seem to be following the same trend, they said in peer-reviewed study in the journal EBioMedicine. The team said they hope to start testing the vaccine candidate on people in clinical trials in the next few months. The potential vaccine uses a needle patch design, called a microneedle array, to increase its potential potency. This array is a fingertip-sized patch of 400 tiny needles made out of sugar and the spike protein, Gambotto explained. It is designed to deliver the spike protein pieces into the skin, where the immune reaction is strongest. Claim: Potential COVID-19 vaccine shows promise in mouse study.
Initial tests in mice of a potential COVID-19 vaccine delivered via a fingertip-sized patch have shown it can induce an immune response against the new coronavirus at levels that might prevent infection, U.S. scientists said on Thursday.

Paragraph: The Department of Public Health said Wednesday that EEE was detected in mosquito samples collected Monday in Easton and New Bedford. No human or animal cases of EEE have been found in the state so far this year and there is no elevated risk level associated with the finding. The virus is generally spread to humans through the bite of an infected mosquito. The last human case of EEE in Massachusetts was in 2013. Last year, a horse and a turkey, both in Worcester County, were diagnosed with EEE. Another mosquito-borne disease, West Nile virus, was detected in Massachusetts for the first this year last week. Claim: EEE detected in Massachusetts for the first time this year.

Massachusetts public health officials say the potentially fatal eastern equine encephalitis virus has been detected in the state for the first time this year.
