What kind of vaccine is Sputnik V, how does it work, and what data are we missing?
Once we achieve herd immunity, people who are not vaccinated benefit indirectly from the immunity of those around them. But it’s not easy to say exactly when we’ll reach this threshold for COVID-19.
The requirement to wear masks in airports lowers the risk of air travel.

Parents face tough choices since young kids can’t yet get COVID-19 vaccinations. An infectious diseases expert offers guidance on navigating summer activities.
New research has found that some men who have had COVID-19 might experience unwanted sexual side effects.

New studies show men who have had COVID-19 could face serious reproductive health issues.
The evidence shows the main way COVID-19 spreads is through the air. I propose 3 steps Australia needs to take to protect people from infection risk and other indoor air hazards.
NSW’s successful test and trace strategy controlled the Crossroads Hotel outbreak a year ago without needing a stringent lockdown. But this has not worked as well against Delta.
Policymakers need to make sense of the data so as to predict and manage what’s happening. To address this need, we developed a visualisation tool to track and predict country-level COVID-19 cases.
Masking indoors will yet again be the new normal in Los Angeles County – and possibly elsewhere in the U.S.

As Los Angeles County again mandates masking indoors – even for the fully vaccinated – local health officials in the U.S. are closely eyeing their own COVID-19 vaccination and infection rates.
As coronavirus cases surge, unvaccinated people are accounting for nearly all hospitalizations and deaths.

The US has split into “two Americas,” one of the unvaccinated and one of the vaccinated. The differences in deaths and hospitalizations between the two populations are striking.
The Lambda variant accounts for almost all new cases in Peru, which has the world’s highest COVID death toll per capita.
Preliminary evidence suggests Lambda has an easier time infecting our cells and is a bit better at dodging our immune systems. But vaccines should still do a good job against it.
Gatherings can lead to the deaths of many people if coronavirus infections spread. It is important for people to stick to regulations such as those about avoiding close contact and confined spaces.

In Hong Kong, SARS created a new social norm, where people accepted mask use as part of their ‘civic responsibility’.

The good news is Victoria is more likely to reach zero case of community transmission sooner if vaccination rates pick up, even modestly.
COVID vaccines don’t contain any live virus to shed. Here’s the science to put the myth of viral shedding after the COVID vaccine to bed.
Security precautions, thoughtful facilities design, careful training and safe lab practices help keep pathogens isolated.

The microbiologist who directs the National Emerging Infectious Diseases Laboratories at Boston University explains all the biosafety precautions in place that help him feel safer in the lab than out.
When children return to schools in the fall, measures to protect them from COVID-19 must be taken/
Simulations of classrooms and offices can help determine the safest configurations to reduce the spread of COVID-19.

South Africa has clearly suffered the consequences of poor strategic decisions to this point. It doesn’t need to continue along these lines.
Delta plus might reduce the efficacy of the vaccines currently in use. But we can’t be sure because we’re yet to see good data on this variant.
Two scientists claim that the genome pairing CGG-CGG is evidence that SARS-CoV-2 was made in a lab.
In February 2021, a World Health Organization team investigating the origins of COVID-19 visited the Wuhan Institute of Virology in Wuhan, China.

The research community is taking a closer look at the lab-leak hypothesis for the origin of COVID-19, prompting discussion about the risks and benefits of engineering viruses.
