Even so, employers may need to be careful about how they handle the process.
Prescreening vaccination questions could violate an A.D.A. provision on disability-related inquiries. Employers administering vaccines, the guidance said, must show that prescreening questions are “job related and consistent with business necessity.”

Answers to Your Vaccine Questions
With distribution of a coronavirus vaccine beginning in the U.S., here are answers to some questions you may be wondering about:
- If I live in the U.S., when can I get the vaccine? While the exact order of vaccine recipients may vary by state, most will likely put medical workers and residents of long-term care facilities first. If you want to understand how this decision is getting made, this article will help.
- When can I return to normal life after being vaccinated? Life will return to normal only when society as a whole gains enough protection against the coronavirus. Once countries authorize a vaccine, they’ll only be able to vaccinate a few percent of their citizens at most in the first couple months. The unvaccinated majority will still remain vulnerable to getting infected. A growing number of coronavirus vaccines are showing robust protection against becoming sick. But it’s also possible for people to spread the virus without even knowing they’re infected because they experience only mild symptoms or none at all. Scientists don’t yet know if the vaccines also block the transmission of the coronavirus. So for the time being, even vaccinated people will need to wear masks, avoid indoor crowds, and so on. Once enough people get vaccinated, it will become very difficult for the coronavirus to find vulnerable people to infect. Depending on how quickly we as a society achieve that goal, life might start approaching something like normal by the fall 2021.
- If I’ve been vaccinated, do I still need to wear a mask? Yes, but not forever. Here’s why. The coronavirus vaccines are injected deep into the muscles and stimulate the immune system to produce antibodies. This appears to be enough protection to keep the vaccinated person from getting ill. But what’s not clear is whether it’s possible for the virus to bloom in the nose — and be sneezed or breathed out to infect others — even as antibodies elsewhere in the body have mobilized to prevent the vaccinated person from getting sick. The vaccine clinical trials were designed to determine whether vaccinated people are protected from illness — not to find out whether they could still spread the coronavirus. Based on studies of flu vaccine and even patients infected with Covid-19, researchers have reason to be hopeful that vaccinated people won’t spread the virus, but more research is needed. In the meantime, everyone — even vaccinated people — will need to think of themselves as possible silent spreaders and keep wearing a mask. Read more here.
- Will it hurt? What are the side effects? The Pfizer and BioNTech vaccine is delivered as a shot in the arm, like other typical vaccines. The injection into your arm won’t feel different than any other vaccine, but the rate of short-lived side effects does appear higher than a flu shot. Tens of thousands of people have already received the vaccines, and none of them have reported any serious health problems. The side effects, which can resemble the symptoms of Covid-19, last about a day and appear more likely after the second dose. Early reports from vaccine trials suggest some people might need to take a day off from work because they feel lousy after receiving the second dose. In the Pfizer study, about half developed fatigue. Other side effects occurred in at least 25 to 33 percent of patients, sometimes more, including headaches, chills and muscle pain. While these experiences aren’t pleasant, they are a good sign that your own immune system is mounting a potent response to the vaccine that will provide long-lasting immunity.
- Will mRNA vaccines change my genes? No. The vaccines from Moderna and Pfizer use a genetic molecule to prime the immune system. That molecule, known as mRNA, is eventually destroyed by the body. The mRNA is packaged in an oily bubble that can fuse to a cell, allowing the molecule to slip in. The cell uses the mRNA to make proteins from the coronavirus, which can stimulate the immune system. At any moment, each of our cells may contain hundreds of thousands of mRNA molecules, which they produce in order to make proteins of their own. Once those proteins are made, our cells then shred the mRNA with special enzymes. The mRNA molecules our cells make can only survive a matter of minutes. The mRNA in vaccines is engineered to withstand the cell’s enzymes a bit longer, so that the cells can make extra virus proteins and prompt a stronger immune response. But the mRNA can only last for a few days at most before they are destroyed.
The guidance comes amid skepticism about the vaccinations among large swaths of the public. A recent poll of about 2,000 New York City firefighters found that nearly 55 percent said they would not get a vaccine if offered one by their department, according to CNN.
Only 42 percent of Black Americans say they intend to be vaccinated, according to a Pew Research poll. And 58 percent of Americans over all indicated they would get a Covid-19 vaccine, according to a Gallup Panel survey from November.
Distrust in vaccinations is also being fanned by political commentators and groups.
On his Fox News show, Tucker Carlson this week highlighted the stories of a small number of Americans who have had adverse reactions to Pfizer’s vaccine. And experts who study extremism have warned that groups that have protested election results and Covid-19 lockdowns across the United States are now turning their attention to the anti-vaccine movement.
The rollout of a vaccine and urgent logistical questions about its distribution signal that the end of the pandemic is in sight, but the virus is also deadlier than it has ever been, with the United States reporting more than 3,000 deaths in a day for the first time this month.
As federal and state governments prepare for large-scale vaccination efforts, the Trump administration’s messaging on the pandemic remains muddled.
Vice President Mike Pence just days ago hosted a holiday party at his residence, where guests posed for pictures without masks, according to attendees. But on Friday morning, Mr. Pence received his first vaccine shot on live television. He was joined by his wife, Karen Pence, and Jerome Adams, the surgeon general.
