But it's important to note that fully vaccinated people should continue to wear face masks and maintain physical distance while in public spaces. Those who are fully vaccinated should also continue to avoid medium and large gatherings and those who are not vaccinated and considered high-risk.
When you get a vaccine, you and your healthcare provider will both need to wear masks that cover your nose and mouth. Stay 6 feet away from others while inside and in lines. Learn more about protecting yourself when going to get your COVID-19 vaccine.
Generally, if you are up to date on your COVID-19 vaccinations, you do not need to wear a mask in outdoor settings. Check your local COVID-19 Community Level for recommendations on when to wear a mask indoors and additional precautions you can take to protect yourself from COVID-19. If you are immunocompromised or more likely to get very sick from COVID-19, learn more about how to protect yourself.
While fully vaccinated people are less likely to transmit the coronavirus to unvaccinated people, it is still possible to spread the virus. Please get tested if you are experiencing COVID-19 symptoms, even after you are fully vaccinated.
Studies of the duration of protection of COVID-19 vaccine effectiveness indicate that vaccine effectiveness decreases more against infection and symptomatic disease than against severe disease in the 6 months after full vaccination.
The most recent research from the CDC suggests that protection from the Pfizer and Moderna COVID-19 vaccines starts to fade around 4 months after a booster dose.
Data released by the U.S. Food and Drug Administration (FDA) show that COVID-19 protection from the Pfizer/BioNTech vaccine was demonstrated in the clinical trials at about 14 days after the first shot. The FDA said some level of immunity may start sooner, but how much is not certain.
Because vaccines are not 100% effective, as the number of people who are fully vaccinated goes up, the number of vaccine breakthrough infections will also increase. However, the risk of infection remains much higher for unvaccinated than vaccinated people.
SARS-CoV-2 is still easily transmitted With breakthrough infections, the viral loads are similar to those who are unvaccinated. That means such infections among fully immunized patients could be transmitted to others who are unvaccinated or have compromised immune systems.
A COVID-19 vaccination may also cause a positive antibody test result for some but not all antibody tests. You should not interpret the results of your SARS-CoV-2 antibody test as an indication of a specific level of immunity or protection from SARS-CoV-2 infection.
Fully vaccinated people can visit privately with other fully vaccinated individuals indoors and without a mask or physical distancing.
Fully vaccinated people can visit with unvaccinated people from a single household who are at a low risk for severe COVID-19 disease, indoors and without a mask or physical distancing.
This is normal and expected, but it doesn't happen to everyone. Even if you feel worse after the second shot, the side effects should still resolve within a few days.
The most commonly-reported events with COVID-19 vaccines are expected vaccine side effects, such as headache, fatigue, muscle and joint pain, fever and chills and pain at the site of injection. The occurrence of these adverse events is consistent with what is already known about the vaccines from clinical trials.
COVID-19 vaccines are safe and effective. Most people have mild side effects or no side effects at all. If you experience fatigue or muscle aches, take a day or two to rest. Or start with a lower-intensity workout, and gradually increase the intensity as your side effects start to go away.
There's a small chance you could catch the coronavirus after you get the vaccine. You might hear this called “breakthrough COVID-19.” Some people who get a breakthrough infection have no symptoms and don't get sick. But a small percentage get ill, go to the hospital, or die from COVID-19.
Breakthrough infections were defined as new cases among persons who were fully vaccinated on the day of specimen collection. Hospitalizations among persons with breakthrough infection were defined as new hospital admissions among persons fully vaccinated on the reporting day.
If you or a loved one had COVID‑19, you're likely wondering how long you might be protected from getting it again. In general, research suggests that natural immunity against infection is strong for about 3-5 months. After that, your risk of COVID‑19 reinfection may start to go up.
It can take days to weeks after an infection for your body to make antibodies.
Although the immune correlates of protection are not fully understood, evidence indicates that antibody development following infection likely confers some degree of immunity from subsequent infection for at least 6 months.
It takes a couple of weeks for your body to build immunity after vaccination.
DURHAM, N.C. – A booster dose of Moderna's COVID-19 vaccine showed signs of waning antibody levels against the Omicron variant after six months, but the antibodies still remained effective against the variant in laboratory tests, according to a Jan. 26 study in the New England Journal of Medicine.
The FDA has authorized three vaccine boosters — Pfizer-BioNTech, Moderna and Janssen/Johnson & Johnson — and determined that it is safe to get a COVID-19 vaccine booster or additional dose that is a different brand than your initial dose or doses.
The bottom line is that if you didn't get your second shot on time, you'll want to get it as soon as possible. If you didn't get your second shot because you developed COVID-19 at some point during the vaccination process, it's still recommended that you get your second dose.
Possible side effects: Pain, redness, or swelling at the site where the shot was administered, and/or tiredness, headache, muscle pain, chills, fever, or nausea throughout the rest of the body. If these side effects occur, they should go away in a few days. A few side effects are serious, but rare.
Commonly reported side effects in the clinical trial included injection site pain (sore arm), redness and swelling, fatigue, headache, muscle and/or joint pain, chills, fever, swollen lymph nodes, nausea and decreased appetite.
