Pfizer CEO Albert Bourla said on Tuesday that he believes it is 'likely' that a strain of COVID-19 could emerge that is resistant to vaccines. However, the pharmaceuticals boss claimed that the company would be able to develop a new shot to tackle a vaccine-resistant strain within 95 days of its emergence, Fox News reported.

The US Food and Drug Administration on Monday granted full approval to the Pfizer/BioNTech Covid-19 vaccine for people age 16 and older. This is the first coronavirus vaccine approved by the FDA, and is expected to open the door to more vaccine mandates. The vaccine will be marketed as Comirnaty, the FDA said in its [...]
TORONTO -- Beth Pardo is an insurance executive, former marathon runner, and one of the first patients to come out with her diagnosis of functional neurological disorder, an issue that surfaced after she got vaccinated against COVID-19.

Viruses originating from birds and animals are known as zoonotic viruses. When these viruses are transmitted to humans through direct or indirect contact with infected populations, they cause a zoonotic spillover. Approximately 70% of infectious diseases over the last three decades are zoonotic. Because no immediate diagnosis or effective cure is available for the [...]
A team of scientists at the University of Huddersfield has discovered chemical systems that self-assemble into molecular capsules which are highly toxic towards human cancer cells of a range of different tumour types, and which have demonstrated unprecedented cancer selectivity in the laboratory that, in some cases, are many thousands of times more toxic [...]
People infected with the Delta variant generally do not have COVID-19 symptoms until two days after they start shedding the coronavirus. People infected with the Delta variant of SARS-CoV-2 are more likely to spread the virus before developing symptoms than are people infected with earlier versions, suggests a detailed analysis of an outbreak [...]
Fully vaccinated adults can harbour virus levels as high as unvaccinated people if infected with the Delta variant, according to a sweeping analysis of UK data, which supports the idea that hitting the threshold for herd immunity is unlikely. There is abundant evidence that Covid vaccines in the UK continue to offer significant protection [...]
Although first detected in December 2019, COVID-19 was inferred to be present in Hubei province, China, for about a month before. Where did this new human disease come from?

"The winner of the game," said chess champion Savielly Tartakower, "is the player who makes the next-to-last mistake." In 1971, John Kerry, then a Navy veteran-turned-antiwar-activist, told a US Senate committee about the horrors of the Vietnam War, posing the devastating question: How can we ask someone "to be the last man to die for a mistake?" With [...]
Looking to the past eradication of diseases, a new paper argues that the global eradication of COVID-19 is possible. The paper quantifies the factors affecting eradicability and scores a few diseases accordingly. The authors of the paper hope and believe that the international disruption that COVID-19 has caused may drive the world’s governments toward [...]
