What kind of vaccine is Sputnik V, how does it work, and what data are we missing?
Investigations have led to the withdrawal of a study backing ivermectin to treat COVID-19. But that’s not the last time we’ll hear about this controversial drug.

Exclusion from clinical trials, lack of data and inconsistent information made it difficult for pregnant and breastfeeding people to make decisions about COVID-19 vaccines early in the rollout.
Put into context, the benefits of vaccination still far outweigh the risks of rare adverse events.

Ongoing tracking is meant to spot very rare risks – like the connection between the Johnson & Johnson shot and Guillain-Barré syndrome. And it relies on public reporting.
The freedom of going mask-free is still a ways off for kids under age 12.

As many teens and adults in the US restart their social lives, parents of children under the age of 12 wonder when their kids will also be able to experience the freedom that comes with vaccination.
Relying on donor funding means that the funder ultimately determines the health priorities. This is one reason why many programmes in Africa focus on a single disease such as HIV.
A new network of public clinical trials institutes is urgently needed to replenish the empty pipeline for new antibiotics.
While it’s potentially promising, there’s not enough information yet to determine if the vaccine is safe and effective.
Even if we came up with a definition of what makes the “best” vaccine, we don’t have the luxury of choice, when vaccines are in short supply.
Alzheimer’s disease is characterized by progressive memory loss, spatial disorientation and many other cognitive and behavioural disorders that ultimately lead to a state of total dependence.
The new drug is based on the idea that a build-up of amyloid in the brain leads to the disease. But that hypothesis has been under scrutiny lately.
Do the benefits of approving a drug before confirming it works outweigh the potential costs?

The FDA approved Alzheimer’s disease drug aducanumab despite minimal evidence of its efficacy. Whether this decision ultimately hurts or helps patients depends on data researchers don’t yet have.
It sounds too good to be true, a vaccine that can protect against future virus variants. But governments around the world are keen to learn more.

We still don’t know if current vaccines prevent people from transmitting the virus to others. Here’s why that matters in 2021.
The reason the vaccine appears to have worked better in participants who initially received only half a dose is still somewhat of a mystery.
Vaccines are being touted as taking seven to ten years to develop. But you shouldn’t be worried that COVID vaccines only took less than a year.

COVID-19 vaccines are at risk of being undermined by vaccine hesitancy. Pharma must take steps to ensure transparency in data monitoring committees and trial data to build public trust in vaccines.
Early data shows that vaccines work for older people who are more at risk of severe COVID-19.
Asking these four questions can help us identify good news when we see it, be more critical of news reports, or delay our judgement until we have more information.
