Nasal Spray Shows Promise in Reducing COVID-19 Risk by 70%

Imagine a simple nasal spray, like the one you might use for allergies.

Scientists are studying if this spray, called azelastine, can also protect you from catching COVID-19.

The study found that people using the spray were much less likely to get infected with the virus.

Out of 450 adults, those using the spray got infected at a much lower rate than those who didn't.

This spray might offer an easy way to add extra protection.

It's available without a prescription in places like the US and Australia.

The most common side effects are a bad taste, occasional nosebleeds, and feeling tired.

The trial had some limitations like a smaller sample size, so scientists need to do more research.
