Vaccine passports became one of the most divisive issues of the COVID-19 pandemic. These policies were affected not only by public opinion but by new variants and changing goals for herd immunity.
The latest addition to the omicron lineage has been making waves in Europe. Whether it will do the same in the U.S. depends on rates of vaccination and prior infection.
The CDC’s controversial recommendation changes are based on new studies showing that most omicron transmission takes place within five days of the onset of illness.
Three months after Omicron abruptly arrived, we now know more about the variant. So what does the science say about how contagious it is, how long it takes to get sick and how effective vaccines are?
COVID-19 variants are the products of the evolution of the SARS-CoV-2 virus. They arise via mutations, but other forces also have roles to play in the generation and transmission of variants.

As we move through the ongoing COVID-19 pandemic, new predictive methods of testing can help monitor the spread of the disease. Environmental testing, like swabbing floors, is a useful tool.
After two years of COVID-19, it’s understandable that many people are weary of infection prevention measures. But simply being tired of the pandemic is no reason to let our guard down.
The arrival of the highly infectious Omicron variant has changed the COVID landscape in Australia. We asked 5 experts whether it’s time to rethink vaccine mandates for dining, fitness and events.
