Vaccinated People Can Transmit the Coronavirus, but It’s Still More Likely If You’re Unvaccinated. COVID-19 vaccines continue to protect against severe illness but do not entirely block transmission. Fully vaccinated people are also less likely to contract the coronavirus than unvaccinated people.

Who should not get the Moderna COVID-19 vaccine?

If you have had a severe allergic reaction (anaphylaxis) or an immediate allergic reaction, even if it was not severe, to any ingredient in an mRNA COVID-19 vaccine (such as polyethylene glycol), you should not get an mRNA COVID-19 vaccine.

Does the COVID-19 vaccine immunity last for life?


How long does protection from a COVID-19 vaccine last? It’s not yet known how long COVID-19 vaccine protection lasts. Recent studies show that protection against the virus may decrease over time.

How long is the stability of the Pfizer-BioNTech COVID-19 vaccine?

Pfizer-BioNTech has submitted data to FDA supporting the stability of their COVID-19 vaccine when stored for up to one month (31 days) at 2°-8°C (standard refrigerator temperature).

Is COVID-19 vaccination still necessary, even after getting the disease and recovering?

Re-infection with COVID-19 occurs, although it is relatively rare. Also, at this point we do not know precisely how long people are naturally protected from getting COVID-19 again after clearing an infection. Follow-up periods for previously-infected individuals are not yet long enough to be able to draw conclusions on the duration of protection against infection beyond six months after infection. As a result, COVID-19 vaccination is recommended even for those who have recovered from the disease.

Is the COVID-19 vaccine safe for people with underlying health conditions?

Clinical trials show that COVID-19 vaccines are safe and effective in people with underlying medical conditions, including those that place them at increased risk for severe COVID-19 symptoms, compared to people without underlying medical conditions.

FDA has authorized the emergency use of the Moderna COVID-19 Vaccine in individuals 18 years of age and older.

How should vaccinated people prevent the spread of COVID-19?

• Wear a mask.

– To maximize protection from the Delta variant and prevent possibly spreading it to others, have

everyone in your family, even those who are vaccinated, wear a mask indoors in public if you are in an area of substantial or high transmission.

– You might choose to have everyone in your family, even those who are vaccinated, wear a mask indoors in public regardless of the level of transmission in your area.

– Unvaccinated family members, including children 2 years and older, should wear a mask in all indoor public settings.

Do you still have to wear a mask if you get the COVID-19 vaccine?

• If you have a condition or taking medications that weaken your immune system, you may not be fully protected even if you are fully vaccinated. You should continue to take all precautions recommended for unvaccinated people, including wearing a well-fitted mask, until advised otherwise by their healthcare provider.

Can you still get COVID-19 after booster vaccine?

COVID-19 is still a risk. Getting a booster shot doesn’t guarantee you won’t be infected with the coronavirus. But it can help your immune system build protection against severe disease or hospitalization — including from the delta variant.

How long after Pfizer COVID-19 vaccine booster is it effective?

The authors explain: “In this study, we estimated effectiveness starting from day 7 after the third dose, which is similar to the period used to define full vaccination after the second dose. Our choice is supported by high concentrations of antibodies in individuals 7 days after administration of the third dose.”

How does the COVID-19 vaccine boost your immune system?

Vaccines work by stimulating your immune system to produce antibodies, exactly like it would if you were exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first.

How long after COVID-19 booster do side effects start?

A separate trial conducted by the Food and Drug Administration produced similar results. Side effects were generally mild to moderate, occurred within two days after vaccination, and most went away within one to two days, the agency said.

Are you at risk of experiencing an autoimmune disease flare-up from COVID-19 vaccine?

There is a risk that flare-ups may occur. That being said, it has been observed that people living with autoimmune and inflammatory conditions are at higher risk of experiencing severe symptoms from a COVID-19 infection.

Can COVID-19 cause an autoimmune disease?

Widespread and long-term inflammation during severe COVID-19 may cause the immune system to produce antibodies to pieces of the virus it wouldn’t normally recognize. Some of those pieces might resemble human proteins enough to trigger the production of autoantibodies.

Can immunocompromised people get the COVID-19 vaccine?

People with immunocompromising conditions or people who take immunosuppressive medications or therapies are at increased risk for severe COVID-19 illness. The currently FDA-approved or FDA-authorized COVID-19 vaccines are not live vaccines and therefore can be safely administered to immunocompromised people.

Is the COVID-19 vaccine safe if you have heart problems?

Not only are the vaccines safe for people with a history of heart disease, they are essential. People with heart disease are at increased risk of severe complications from COVID-19.

So far, no data suggests that COVID-19 vaccines cause an increase in blood pressure.

If you were treated for COVID-19 with monoclonal antibodies or convalescent plasma, you should wait 90 days before getting a COVID-19 vaccine.

Can you get reinfected with COVID-19?

Based on what we know from similar viruses, some reinfections are expected. We are still learning more about COVID-19.

Most people who get COVID-19 are unvaccinated. However, since vaccines are not 100% effective at preventing infection, some people who are fully vaccinated will still get COVID-19. An infection of a fully vaccinated person is referred to as a “breakthrough infection.”

Do we still need to wear a mask after getting a COVID-19 vaccine?

After you are fully vaccinated for COVID-19, take these steps to protect yourself and others:

• In general, you do not need to wear a mask in outdoor settings.

• If you are in an area with high numbers of COVID-19 cases, consider wearing a mask in crowded outdoor settings and when you are in close contact with others who are not fully vaccinated.

• If you have a condition or taking medications that weaken your immune system, you may not be fully protected even if you are fully vaccinated. You should continue to take all precautions recommended for unvaccinated people, including wearing a well-fitted mask, until advised otherwise by their healthcare provider.

• If you are fully vaccinated, to maximize protection from the Delta variant and prevent possibly spreading it to others, wear a mask indoors in public if you are in an area of substantial or high transmission.
