COVID

San Francisco Mayor London Breed has again flouted the pandemic-control measures she previously insisted everyone else follow. She's a hypocrite for doing so, but her behavior illustrates an important lesson about the risk posed by COVID-19.
Scientific American says there's good evidence to support mandatory masking in schools. A careful look at the data suggest the situation is more complicated.
Given the abundance of readily available, free, effective (albeit imperfect) vaccines for many months, why are we seeing a surge in COVID cases and hospitalizations? Let's examine the three primary factors that dictate the severity of an outbreak of a viral illness.
As the Biden Administration's booster shot roll out approaches, we have plenty of evidence that the primary COVID vaccines are still very effective, a growing number of experts say, but very little data to justify widespread use of boosters. This kind of open policy debate is exactly what we need.
Yet another study has found that the authorized COVID-19 vaccines greatly reduce infection. Let's take a look at this latest paper in the context provided by previously published research on vaccine efficacy.
The evidence is in: genetic engineering promotes sustainable farming, vaccines save lives, and nuclear energy is our best hope of powering society in a changing climate. But the question remains, how do you convince a generally skittish public to embrace the science behind these technologies? Our answer: make a movie.
A new clinical trial examining the efficacy of masking on COVID-19 transmission has garnered a lot of media coverage. What the study shows and what people have been told the study shows are very different.
 It has been sixty years since the Concert for Bangladesh; It is doubtful that this low-income country, with half the population and 1/66th the size of the US, has had as much coverage in the media as now, with a report on the efficacy of masks in fighting COVID-19. It is a well-thought-out, performed, and reported study and deserves better than the superficial reporting of the media and 280 character Tweets. Let me provide a deeper look.
California just paused its plans for a statewide COVID-19 vaccine mandate. There wasn't an ounce of scientific evidence to support this proposal and enough opposition to halt the legislation, at least until after the upcoming elections. There's an important lesson here for policymakers.
Anti-vaccine group Children's Health Defense is abusing a new study of COVID-19 breakthrough cases to badmouth very effective shots.
In their rush to correct "misinformation" about the efficacy of masks, fact-checkers have obscured some important limitations surrounding the science they insist we all follow.
Despite its higher transmissibility, research continues to show that the authorized COVID-19 vaccines protect against the Delta variant. The latest evidence comes to us from the UK.
