Oxford-AstraZeneca vaccine is cheaper than Pfizer's and Moderna's and doesn't require supercold temperature

There is now a third vaccine that prevents COVID-19 infections. It isn't quite as effective as the other two vaccines but it has advantages that may make it the frontrunner.

COVID-19 vaccines were developed in record time – but are these game-changers safe?

Because Pfizer-BioNTech and Moderna vaccines have been developed in record time, many wonder whether companies cut corners or compromised safety.

Keeping indoor air clean can reduce the chance of spreading coronavirus

Being indoors with other people is a recipe for spreading the coronavirus. But removing airborne particles through proper ventilation and air filtration can reduce some of that risk.

How mRNA vaccines from Pfizer and Moderna work, why they're a breakthrough and why they need to be kept so cold

There are two new COVID-19 vaccines that appear to be more than 90% effective. But what are these vaccines, and how are they different from those used previously?

No, soaring COVID-19 cases are not due to more testing – they show a surging pandemic

COVID-19 cases are skyrocketing across the US. Testing has ramped up over the past few months, but increasing hospitalizations, deaths and test-positivity rates show that the virus is out of control.

Virus evolution could undermine a COVID-19 vaccine – but this can be stopped

As viruses are transmitted from person to person they are constantly mutating and replicating. Could the SARS-CoV-2 virus evolve to evade the new vaccines that have just been developed?

What monoclonal antibodies are – and why we need them as well as a vaccine

Monoclonal antibodies are synthetic molecules manufactured in the lab. But do we need them if a vaccine is on its way?

Achieving COVID-19 herd immunity through infection is dangerous, deadly and might not even work

Some have suggested the US allow healthy people to return to normal life, catch the coronavirus and get the population to herd immunity. The science says this plan is doomed to fail from the start.

COVID-19 causes some patients' immune systems to attack their own bodies, which may contribute to severe illness

Are antibodies that attack a patient's own organs contributing to severe forms of COVID-19? A new study suggests specific antibody tests that may reveal the answer.
