💉This sleepy town in Brazil is running a huge coronavirus vaccine experiment

The aim is to track the real-world impact of jabs, as scientists work to understand how effective Covid vaccines are at halting transmission

@djknowles22 explains the science behind the methodology⬇️
🇧🇷As the pandemic hits new heights in Brazil and its vaccination drive stutters, Serrana's residents can barely believe their luck: every adult has been offered at least one dose of a Covid-19 shot

@sneweyy reports:

🗺️Serrana – a hard-hit commuter town in São Paulo state home to some 45,000 people – was chosen last autumn to host ‘Project S’

The study, which is the first of its kind, aims to answer looming questions about the real-world impacts of coronavirus jabs
📌By vaccinating the entire city in stages researchers hope to track whether someone who is inoculated can still transmit the virus, and how quickly vaccines contain the pandemic
🧪 The study is testing CoronaVac, a jab developed by the Chinese company Sinovac and manufactured by the Butantan Institute

The jab, alongside the AstraZeneca vaccine, has become a mainstay of Brazil’s faltering vaccination campaign
🩺 Clinical trials in Turkey and Brazil suggest the CoronaVac jab prevents 100% of hospitalisations and deaths, but it halts only 50% of infections
🔐The study was organised in secret to prevent a mass influx of people to the town (though this hasn’t stopped a surge in inquiries to estate agents in the last six weeks)
The results are yet to be published. But with Brazil’s coronavirus outbreak growing worse by the day, all eyes are now on Serrana

🚨 #Breaking The leaked @WHO report says virus most probably jumped from bats and then into farmed animals before spreading to humans

telegraph.co.uk/global-health/…
The highly anticipated World Health Organization report on the origins of Sars-Cov-2 has concluded that a leak from a laboratory, while possible, is “extremely unlikely”
Instead, the virus is most likely to have been passed from bats via an “intermediate animal host” to humans before sparking an “explosive outbreak” in Wuhan in December 2019

While the picture is broadly positive in the UK, the third wave of the coronavirus is causing devastation in countries like Brazil

@jriggers reports 🧵
The country reported 3,000 daily deaths on Tuesday and is close to reaching 300k deaths in total from the virus

“We are close to or facing a catastrophe,” a medical bulletin read last week, adding that intensive care occupancy is above 90% across half of its 26 states
And while Brazil is currently the epicentre of the latest Covid resurgence the picture is worrying in a number of other regions, the @who says

After six weeks of declining numbers of fatalities the death rate rose by 3% globally in the last seven days to 60,414 in total Map showing deaths per million

🦠 Health authorities are scrambling to halt a new Ebola outbreak

@ItsBillyMate explains what we know so far

1/
There are two unrelated outbreaks: one in Guinea & the Democratic Republic of Congo

While the DRC is battling a resurgence of the disease, all eyes are on West Africa where Ebola sparked the world’s worst outbreak between 2013-2016

@sneweyy reports
telegraph.co.uk/global-health/…
Guinea's first case was detected in a nurse who died in late January

Already at least seven people who attended her funeral have reported symptoms, including five people who have died

Others have been isolated in treatment centres, but experts warned more cases may emerge

The sunny days of Lockdown One feels very far away and if you're feeling fatigued, you're not alone.

But just why does this lockdown feel so different this time round?

The answer, as our editor @paulnuki explains, is in the data
🧑‍⚖️The rules have changed

A sense of not-quite normality may be playing a part as essential work has been defined more broadly, meaning more people can travel to and from work, and there is no longer a limit on daily exercise
🌨️The winter weather is definitely impacting our mood

Gone are the sunny days in the garden and parks that came with Lockdown One
