The current COVID vaccines are our most powerful tool to fight all the strains of COVID-19.

How effective is the Moderna COVID-19 vaccine?

How Well the Vaccine Works

  • Based on evidence from clinical trials, in people aged 18 years and older, the Moderna vaccine was 94.1% effective at preventing laboratory-confirmed COVID-19 infection in people who received two doses and had no evidence of being previously infected.

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.

Can I get the COVID-19 vaccine if I have an underlying condition?

People with underlying medical conditions can receive a COVID-19 vaccine as long as they have not had an immediate or severe allergic reaction to a COVID-19 vaccine or to any of the ingredients in the vaccine. Learn more about vaccination considerations for people with underlying medical conditions. Vaccination is an important consideration for adults of any age with certain underlying medical conditions because they are at increased risk for severe illness from COVID-19.

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.

What are some of the common side effects of Pfizer COVID-19 vaccine booster shots?

Fatigue and pain at the injection site were the most commonly reported side effects, and overall, most side effects were mild to moderate. However, as with the 2-shot primary series, serious side effects are rare, but may occur.

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.

Can you get COVID-19 after being vaccinated?

Vaccinated people can still become infected and have the potential spread the virus to others, although at much lower rates than unvaccinated people. The risks of SARS-CoV-2 infection in fully vaccinated people are higher where community transmission of the virus is widespread.

Does the COVID-19 vaccine work on new mutations?

There is promising evidence to suggest that the current vaccines will protect you from most variants, or mutations, of COVID-19 that are currently spreading in the United States. It is possible that some variants might cause illness in some people after they are vaccinated. However, if a vaccine is found to be less effective, it could still offer some protection. Researchers are monitoring how the new COVID-19 variants may affect how vaccines will work in real-world scenarios. To learn more about vaccines and new variants, visit the Centers for Disease Control and Prevention. (Last updated 06/15/2021)

How long will it take to build immunity after getting the COVID-19 vaccine?

It takes time for your body to build protection after any vaccination. People are considered fully vaccinated two weeks after their second shot of the Pfizer-BioNtech or Moderna COVID-19 vaccine, or two weeks after the single-dose J&J/Janssen 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.

What happens if you don’t take the second shot of the COVID-19 vaccine?

Put simply: Not receiving the second vaccine increases your risk of contracting COVID-19.

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.

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.

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.”

Do COVID-19 vaccine boosters work?

Results from Israel indicate that a booster dose greatly lowers the risk of severe illness. Boosters also prevent infection. This reduces the spread of SARS-CoV-2 among vaccinated and unvaccinated individuals. It isn’t yet clear how long protection from boosters will last, but the world can’t wait to find out.

What does a booster shot do?

Typically, you would get a booster after the immunity from the initial dose(s) naturally starts to wane. The booster is designed to help people maintain their level of immunity for longer.

How long do the side effects of the COVID-19 booster usually last?

They’re very similar to what happens after the second dose, which is that you do tend to get pain at the injection site, usually just lasts a few days, and usually it’s not severe. And then you can get systemic side effects such as fever, fatigue, headache, and again, that usually goes away after a day or two.

Is it normal to have side effects after second COVID-19 vaccine?

Side effects after your second shot may be more intense than the ones you experienced after your first shot. These side effects are normal signs that your body is building protection and should go away within a few days.

How long does side effects from the COVID-19 vaccine last?

COVID-19 vaccination will help protect you from getting COVID-19. You may have some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. Some people have no side effects.

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.

Should you get the Covid vaccine if you have an autoimmune disease?

The American College of Rheumatology COVID-19 Vaccine Clinical Guidance recommends that people with autoimmune and inflammatory rheumatic disease (which includes lupus) get the vaccine unless they have an allergy to an ingredient in the vaccine.

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.

What is the difference between Pfizer and Moderna vaccine?

Moderna’s shot contains 100 micrograms of vaccine, more than three times the 30 micrograms in the Pfizer shot. And Pfizer’s two doses are given three weeks apart, while Moderna’s two-shot regimen is administered with a four-week gap.

Are the Pfizer and Moderna COVID-19 vaccines interchangeable?

COVID-19 vaccines are not interchangeable. If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot. You should get your second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor tells you not to get it.

Is Pfizer COVID-19 booster same as original vaccine?

The boosters will be an extra dose of the original vaccine. Manufacturers still are studying experimental doses tweaked to better match delta. There’s no public data yet that it’s time to make such a dramatic switch, which would take more time to roll out.

How long does it take to build up immunity to COVID-19 after receiving the vaccine?

COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. It typically takes a few weeks after vaccination for the body to build protection (immunity) against the virus that causes COVID-19. That means it is possible a person could still get COVID-19 just after vaccination.

Should I wear a mask if I am vaccinated against COVID-19?

•Even if you are fully vaccinated, if you live in an area with substantial or high transmission of COVID-19, you – as well as your family and community – will be better protected if you wear a mask when you are in indoor public places.

Does the COVID-19 vaccine prevent transmission?

Evidence suggests the U.S. COVID-19 vaccination program has substantially reduced the burden of disease in the United States by preventing serious illness in fully vaccinated people and interrupting chains of transmission.

Can I get the COVID-19 vaccine if I have an underlying condition?

People with underlying medical conditions can receive a COVID-19 vaccine as long as they have not had an immediate or severe allergic reaction to a COVID-19 vaccine or to any of the ingredients in the vaccine. Learn more about vaccination considerations for people with underlying medical conditions. Vaccination is an important consideration for adults of any age with certain underlying medical conditions because they are at increased risk for severe illness from COVID-19.

What happens if COVID-19 mutates?

Thanks to science fiction, the word “mutant” has become associated in popular culture with something that is abnormal and dangerous. Yet in reality, viruses like SARS-CoV-2, the virus that causes COVID-19, are mutating all the time and often this process does not have any impact on the risk the virus poses to humans.

Should you get vaccinated for COVID-19 if you have an autoimmune disease?

People with autoimmune conditions may receive any currently FDA-authorized COVID-19 vaccine. If people with these conditions are immunocompromised because of medications such as high-dose corticosteroids or biologic agents, they should follow the considerations for immunocompromised people.

How effective is the Pfizer COVID-19 vaccine?

• Based on evidence from clinical trials in people 16 years and older, the Pfizer-BioNTech vaccine was 95% effective at preventing laboratory-confirmed infection with the virus that causes COVID-19 in people who received two doses and had no evidence of being previously infected.

What is the difference between a Pfizer COVID-19 booster and a regular Pfizer COVID-19 shot?

“There is no difference between the additional, or third doses, and booster shots. The only difference is who may qualify to receive them,” the CDC said when News10 reached out to them.

What happens if you don’t take the second shot of the COVID-19 vaccine?

Put simply: Not receiving the second vaccine increases your risk of contracting COVID-19.

Do I need to discontinue my medications after receiving the COVID-19 vaccine?

For most people, it is not recommended to avoid, discontinue, or delay medications that you are routinely taking for prevention or treatment of other medical conditions around the time of COVID-19 vaccination.

What does it mean to be fully vaccinated for COVID-19?

Fully vaccinated persons are those who are ≥14 days postcompletion of the primary series of an FDA-authorized COVID-19 vaccine. Not fully vaccinated persons are those who did not receive an FDA-authorized COVID-19 vaccine or who received vaccine but are not yet considered fully vaccinated.

Will getting a COVID-19 vaccine cause me to test positive for COVID-19 on a viral test?

No. None of the authorized and recommended COVID-19 vaccines cause you to test positive on viral tests, which are used to see if you have a current infection.​

If your body develops an immune response to vaccination, which is the goal, you may test positive on some antibody tests. Antibody tests indicate you had a previous infection and that you may have some level of protection against the virus.

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 do you build an immunity against COVID-19?

Vaccinations are the best option to developing immunity against the new coronavirus. In addition, the hope is that people who’ve been exposed to COVID-19 also develop an immunity to it. When you have immunity, your body can recognize and fight off the virus.

Will I be fully protected after COVID-19 vaccination if I have a weakened immune system?

If you have a condition or are taking medication that weakens your immune system, you may NOT be fully protected even if you are fully vaccinated. Talk to your healthcare provider. Even after vaccination, you may need to continue taking all precautions.

What is the difference between a Pfizer COVID-19 booster and a regular Pfizer COVID-19 shot?

“There is no difference between the additional, or third doses, and booster shots. The only difference is who may qualify to receive them,” the CDC said when News10 reached out to them.

What is the difference between COVID-19 booster and third shot?

“A booster shot is for people whose immune response may have weakened over time,” Roldan said. “A third dose is for people who may not have had a strong enough immune response from the first two doses.” Consult your health care provider about which might be right for you.

Who should get the Pfizer COVID-19 booster shot?

The federal health agency said anyone 65 or older, anyone in long-term care, or aged 50 to 64 but with underlying health conditions, should get the booster. The CDC added that anyone 18 to 49 with underlying health issues or workers like nurses, first responders and other high-risk jobs also may get the booster.

Can you mix AstraZeneca and Pfizer vaccine?

The CDC currently recommends against combining the various shots, but preliminary research found that mixing the AstraZeneca vaccine with Pfizer can produce an even stronger immune response than two doses of one type alone.

Can I get a Pfizer booster if I had the Moderna vaccine for COVID-19?

Boosters for all patients must be given at least six months after an initial Pfizer vaccine course. Patients who received initial doses of the vaccines made by Moderna Inc. and Johnson & Johnson aren’t eligible yet. Approval of a booster regimen for those patients is expected in the coming months.
