LHSFNA Vaccine Facts


Are the COVID-19 vaccines safe?

Yes. All authorized COVID-19 vaccines have gone through the same rigorous procedures and safety tests and met the same standard as vaccines for other diseases. A system called v-safe – an after vaccination health checker – is in place across the U.S. so the CDC can make sure the vaccines stay safe.

How effective are the COVID-19 vaccines?

The Pfizer/BioNTech vaccine is 95 percent effective and the Moderna vaccine is 94 percent effective at preventing mild and severe symptoms of COVID-19. This effectiveness holds across age, sex and racial and ethnic groups. The Johnson & Johnson vaccine is 85% effective at preventing severe/critical COVID-19 infection. All of the COVID-19 vaccines prevent severe disease, hospitalization and death.


What are the benefits of getting a COVID-19 vaccine?

In addition to helping protect against infection, the vaccine will help keep you from getting seriously sick if you do get COVID-19. It’s much safer than the natural protection that comes with getting and recovering from COVID-19. This disease can have serious, life-threatening complications and lasting health effects.


Can I transmit COVID-19 to others after I get the vaccine?

Potentially. Getting vaccinated may also protect people around you, but more research is needed before we can say for certain whether someone who has had the vaccine can still transmit the virus. So while the vaccine is key to helping stop the pandemic and returning our lives to normal, it’s only one piece of the puzzle.

Can a COVID-19 vaccine make me sick with COVID-19?

No. The vaccines in the U.S. don’t contain the live virus that causes COVID-19, so you can’t get COVID-19 from the vaccine.

After getting a COVID-19 vaccine, will I test positive on a viral test?

No. The vaccines in the U.S. can’t cause you to test positive. Viral tests only show a current COVID-19 infection.

Do I still need to wear a mask and socially distance after I get the vaccine?

Yes. Vaccine availability will be limited at first, and immunizing enough of the population to stop the virus from spreading will take time. The vaccine is one tool in your toolbox to protect you from COVID-19; masks, distancing and hand hygiene are other tools.
