Coronavirus facts, myths and information: Your questions, answered

What should I do if I’m wearing a mask but have to sneeze?

If there are tissues nearby, you can take your mask off and sneeze into the tissue before putting your mask back on, CNN Chief Medical Correspondent Dr. Sanjay Gupta said.

For kids in school — or anyone else who might have to wear a mask all day — bring a backup mask in a baggie in case the first mask gets dirty. You can put the dirty mask in the baggie.

It’s also a good idea to keep backup masks in your car in case of any mask accidents.

Since there are multiple vaccines in trials, what happens if you get a vaccine ASAP, but a more effective one comes out later? Can you get more than one Covid-19 vaccine?

It’s too early to say for sure with Covid-19 vaccines, said Dr. Francis Collins, director of the National Institutes of Health.

“But that’s certainly plausible,” Collins said. “Look at where we are with shingles right now, where we had a vaccine that was pretty good, and then there was one that was a lot better, and everybody took both.”

If a pregnant woman gets Covid-19, will her baby be infected? Can babies get coronavirus through breastfeeding?

What are the guidelines for riding in a vehicle with someone from another household?

People from different households riding in a car together should wear face masks, said Dr. Aaron Hamilton of the Cleveland Clinic.

“You should also wear one if you’re rolling down your window to interact with someone at a drive-thru or curbside pickup location,” Hamilton said.

It’s also smart to keep the windows open to help ventilate the car and add another layer of safety, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.

My kid hates the idea of nasal swabs. Is there a saliva test for Covid-19?

The SalivaDirect test could soon be a fast and cheap option. “We simplified the test so that it only costs a couple of dollars for reagents, and we expect that labs will only charge about $10 per sample,” said Nathan Grubaugh, one of the Yale researchers who developed the test.

The SalivaDirect test can produce results in less than three hours, and the accuracy is on par with results from traditional nasal swabbing. The Yale researchers said it might become publicly available in the coming weeks.

Is it true a vaccine could be approved and sent out before it’s fully tested?

Not exactly. It’s possible the Food and Drug Administration could give an emergency use authorization — not an approval — for an experimental Covid-19 vaccine before its Phase 3 trial is complete.

At least three coronavirus vaccines are in Phase 3 clinical trials in the United States. Phase 3 is often the last phase of vaccine development, when thousands of volunteers are injected and monitored to further check for safety and efficacy.

But the independent Data and Safety Monitoring Board could stop a trial early if the interim results are overwhelmingly positive and board members deem the vaccine safe and effective. In that case, researchers would have “a moral obligation” to end the trial early and speed up the process to give the vaccine to millions, Dr. Anthony Fauci told Kaiser Health News.

“If you look at the projection, of the enrollment (of trial participants) and the kinds of things you’ll need to get a decision about whether the vaccine is safe and effective, most of us project that that’s going to be by November, December, by the end of the year,” Fauci told CNN.

“Could this be earlier? Sure,” he said. “That’s…
