Farmacêutica americana inicia 3ª fase de vacina contra covid-19

Farmacêutica Moderna entrará na terceira fase dos testes de vacina contra covid-19 Lewis Whyld/EFE - 12.07.2020

A farmacêutica americana Moderna anunciou neste domingo (26) que começará nesta segunda-feira (27) a terceira fase de testes da vacina experimental contra a covid-19, e que conseguiu dobrar o financiamento governamental do projeto para US$ 955 milhões.

Em comunicado, a empresa afirmou que modificou o contrato com a Autoridade de Pesquisa e Desenvolvimento Avançado de Biomedicina (BARDA, na sigla em inglês) para ampliar em US$ 472 milhões a quantia inicial destinada ao desenvolvimento da vacina mRNA-1273, que entra agora em estágio avançado.

“Após conversas com a Administração de Alimentos e Fármacos (FDA) e com a Operação Warp Seed nos últimos meses, a empresa decidiu executar uma terceira fase significativamente maior do teste clínico, fechando uma lacuna no financiamento da BARDA graças a esta modificação no contrato”, explicou.

O contrato original com o órgão previa U$ 483 milhões à Moderna para o desenvolvimento da vacina mRNA-1273, que inicialmente teria um “número menor de participantes na terceira fase”, em comparação com os 30 mil voluntários necessários nos Estados Unidos.

A Moderna comunicou que, ao iniciar nesta segunda-feira a terceira fase do teste, dirigido pelo Instituto Nacional de Alergias e Doenças Infecciosas dos EUA, se torna a primeira empresa da corrida americana pela vacina a entrar nesta etapa avançada.

Nesta fase, 30 mil participantes receberão aleatoriamente uma dose de 100 microgramas do fármaco ou uma dose de placebo com o objetivo principal de comprovar se pode “prevenir os sintomas de covid-19”, além de prevenir a infecção do coronavírus SARS-CoV-2 e casos graves.

“Agradecemos à BARDA pelo contínuo compromisso com a mRNA-1273, nossa vacina candidata contra a covid-19”, destacou em comunicado o diretor executivo da Moderna, Stéphane Bancel, ao afirmar que os dados “alentadores” da primeira fase levam a empresa a pensar que é possível “ajudar a lidar com a pandemia e prevenir futuros surtos”.

Os Estados Unidos já registraram 4,18 milhões de casos de covid-19, incluindo mais de 146 mil mortes, de acordo com a contagem independente realizada pela Universidade Johns Hopkins.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
