Are The Covid Vaccines Safe

Here’s how long you should wait for your mammogram after getting the COVID-19 vaccine

Yes, the coronavirus vaccines are safe and effective, and will give you the best protection against Covid-19. While they were developed far quicker than the average 8-10 years required for previous vaccines, this is because of the massive effort by researchers, the money invested by governments, and the willingness of volunteers to trial them.

All vaccines approved were rigorously tested before being approved, and have met the strict standards of safety, quality and effectiveness set out by the MHRA.

Vaccines are the most effective way to prevent infectious diseases and save up to 3 million lives worldwide every year. Thanks to vaccine roll-outs in the past, diseases like smallpox, polio and tetanus no longer exist or are very rare.

Read why vaccination is safe and important.

What Should You Do If You’re Experiencing Covid Vaccine Side Effects

Mild Covid vaccine side effects are common but not everyone will get them. Side effects usually last 1-3 days, but can last up to 1 week. If you do experience symptoms, its still important to have your second dose. The second dose of the vaccine will give you the best protection against the virus.

If you are experiencing side effects:

  • Rest until you feel better.
  • Take the normal dose of paracetamol to help ease mild symptoms.
  • If your symptoms seem to get worse or if you are concerned, call NHS 111.
  • If you do seek advice from a doctor or nurse, let them know youve been vaccinated and show them your vaccination card so that they can assess you properly.

You can also report suspected side effects of vaccines and medicines online through the Yellow Card scheme.

How Long Should You Quarantine Or Isolate

First, you’ll need to know the difference between whether you must quarantine or isolate. Those who believe they have been in contact with someone who has COVID and are unvaccinated should quarantine. Those who test positive, regardless of vaccination status, must isolate, according to the CDC.

Close contact is defined by the CDC and the Illinois Department of Public Health as “someone who was less than 6 feet away from an infected person for a cumulative total of 15 minutes or more over a 24-hour period.”

Here’s the breakdown:


If you come into close contact with someone with COVID-19, you should quarantine if you are not up-to-date on COVID-19 vaccines or are unvaccinated. For these individuals, the CDC and IDPH recommend you:

  • If possible, stay away from people you live with, especially people who are at higher risk for getting very sick from COVID-19, as well as others outside your home throughout the full 10 days after your last close contact with someone with COVID-19.
  • If you are unable to quarantine, you should wear a well-fitting mask for 10 days when around others at home and in public.
  • If you are unable to wear a mask when around others, you should continue to quarantine for 10 days. Avoid people who have weakened immune systems or are more likely to get very sick from COVID-19, and nursing homes and other high-risk settings, until after at least 10 days.
  • Isolation

    When Do Experts Expect Travel To Get Back To Normal Again

    It is going to take many months and a very strong vaccine effort to make travel normal again. Travel within the U.S. is opening up, especially for vaccinated people, which is a good sign. But even though people 12 years of age and older in the U.S. currently have access to a vaccine, only 35% of Americans are fully vaccinated.

    It will take longer for traveling abroad to get back up to speed. Several airlines have reduced flights and some areas of the world are still locked down. Experts predict things wont normalize until late 2021 or even mid-2022.

    Special Instructions For Immunocompromised People

    Heres how long after the second dose of the COVID vaccine it is safe ...

    Immunocompromised people ages 5+ who received Pfizer: If you are fully vaccinated with Pfizer, 28 days after your second shot, you can receive a third dose.

    Immunocompromised people ages 12+ who received Pfizer: 5 months after the third dose, you can receive a booster . The booster must be Pfizer for ages 12 years to 17 years of age, and can be any of the available vaccines for those 18 years and older.

    Immunocompromised people ages 18+ who received Moderna: If you received two doses of Moderna, 28 days after your second shot, you can receive a third, full dose. Five months after the third dose, you can receive a booster of any of the available vaccines. Henry Ford offers boosters of Pfizer.

    Immunocompromised people ages 18+ who received Johnson & Johnson: You can receive a booster of any available vaccine two months after the original dose.

    After Youve Been Vaccinated

    Stay for monitoring. The health care provider should observe you for about 15 minutes after the vaccine is administered to make sure you dont have any immediate reactions. However, it is extremely rare for severe health reactions.

    Be prepared for some side effects. Vaccines are designed to give you immunity without the dangers of getting the disease. While its normal to build immunity without side effects, its also common to experience some mild-to-moderate side effects that go away within a few days on their own.

    Some of the mild-to-moderate side effects you may experience after vaccination include:

    • Arm soreness at the injection site
    • Mild fever
    • Chills
    • Diarrhoea

    If any symptoms continue for more than a few days or if you experience a more severe reaction, then contact your health care provider immediately.

    Be patient. Building immunity takes time. You will be considered fully vaccinated two weeks after your second dose of the Pfizer-BioNtech or Moderna COVID-19 vaccine, 15 days after your second dose of the AstraZeneca vaccine or two weeks after the single-dose J& J/Janssen COVID-19 vaccine.

    This Is Typically The Case Surrounding Vaccines And Other Medical Treatments

    There is nothing unusual about the COVID vaccines in this sense. In short, like all vaccines, they trigger a response from your immune system and while your body is temporarily behaving differently as a result of that, regular medical treatments may go differently.

    For example, because a small number of people experienced facial swelling from the Moderna vaccine, doctors don’t recommend that you book dermal fillers during the two weeks on either side of your vaccination. “What’s going on is that we want a robust immune response from the COVID-19 vaccine. So anything that would interfere with it should be avoided,” Vyas says. And for more about Moderna, check out The One Side Effect That’s Much More Common With Moderna, Data Shows.

    Booster shots are recommended for everyone age 12 years and older. Additional populations may be recommended to receive a booster shot as more data becomes available. The COVID-19 vaccines approved and authorized in the US continue to be effective at reducing risk of severe disease, hospitalization, and death. However, the virus that causes COVID-19 is continually evolving. Experts are reviewing all available data to understand how well the vaccines are working for different populations. This includes looking at how variants, like Delta and Omicron, affect vaccine effectiveness.

    Doctors Are Advising That You Don’t Do Any Steroid Shots Close To Your Covid Vaccine

    How long after receiving a COVID-19 vaccine will it be effective?

    The Spine Intervention Society’s interim advice is currently to keep a period of two weeks between your COVID vaccine and your regular steroid shots. “It may be prudent, based on indirect evidence, to schedule elective corticosteroid injection approximately two weeks before vaccine administration and no later than one week before vaccine administration to avoid potential decrease in immunogenicity of the mRNA vaccines,” they advise.

    While some other experts’ timelines vary slightly, the general consensus is the same. Michaela Schneiderbauer, MD, of Southern Vermont Health Care recently wrote: “While conclusive evidence is not yet available to recommend for or against using steroids around COVID-19 vaccinations, the providers at SVMC Orthopedics are recommending that our patients hold steroid injections in the two weeks before and one week after administration of COVID-19 vaccine.” And for more COVID news sent right to your inbox, .

    Im Allergic To A Number Of Medications Including Penicillin Can I Still Have The Vaccine

    None of the Covid vaccines contain penicillin.

    Both the Pfizer/BioNTech and Moderna vaccines contain a compound called Polyethylene glycol used to stabilise the lipid particles in the vaccine, and the Oxford/AstraZeneca vaccine contains Polysorbate-80 .

    Both of these compounds are closely related, and are found in many other medications.If you have a known severe allergy or anaphylactic reaction to either of these compounds, or have had an unexplained severe reaction in the past you should discuss vaccination with your GP or health professional.

    Will I Receive Anything To Show Proof Of Vaccination

    You should receive a vaccination card or printout that tells you what COVID-19 vaccine you received, the date you received it, and where you received it. Please be sure to keep this card for your second dose. You may take a photo of your card as a backup digital copy.

    You should receive a paper or electronic version of a fact sheet that tells you more about the specific COVID-19 vaccine you are being offered. Each COVID-19 vaccine has its own fact sheet that contains information to help you understand the risks and benefits of receiving that specific vaccine: Comirnaty/Pfizer, Moderna, and Johnson & Johnson .

    How Long You Must Quarantine During A Covid

    Recently updated guidelines set forth by CDC officials indicate that those who test positive for COVID-19 must be isolated at home for at least five days. These guidelines indicate that sick individuals should only break their isolation if they’ve been free of a fever, without the help of medication, for at least 24 hours.

    As of May 19th, over 45% of the U.S. population is in an area with a medium or high COVID-19 Community Level.At high COVID-19 Community Levels, people should be masking.At medium levels, people should consider masking based on personal risk.

    Rochelle Walensky, MD, MPH May 20, 2022

    But experts add that those who continue to test positive via rapid, at-home tests should still be considered infectious, and remain quarantined to minimize the risk of getting others around them sick.

    “In patients who are largely asymptomatic, staying isolated to prevent spread to family members and close contacts particularly if those contacts are immunocompromised or elderly is important, with no specific treatment beyond rest indicated,” Dr. Wright says.

    Your recovery period may be lessened if you take advantage of current antiviral treatments, including the prescribed outpatient treatment Paxlovid, as well as a few other options.

    Doctors Support The Change

    How Long After Getting Infected Can You Get The COVID Vaccine?

    Richard Watkins, MD, an infectious disease physician and a professor of internal medicine at the Northeast Ohio Medical University, tells Verywell that there was never any compelling evidence for the previous recommendation, adding, I am glad it has been changed.

    Watkins says that the move may help more children get vaccinated, noting the convenience factor. Under the updated guidance, families only have to make one trip to get vaccinated instead of several under the previous recommendations, he says.

    John Schreiber, MD, a pediatric infectious disease specialist at Connecticut Children’s Medical Center, tells Verywell that the changed guidance seems like a reasonable thing to do.

    Schreiber anticipates that some parents may still be wary to give their children other vaccines at the same time as the COVID-19 vaccine, but say that new recommendations are sound.

    I dont have any concerns with this, Schreiber says. But, he adds, the CDC and AAP will monitor children to see what happens next. If it turns out that children are complaining about more side effects after getting vaccinated, Im sure the recommendations can be modified.”

    The Vaccines Are Very Effective And May Help Reduce The Severity Of The Disease

    In Phase 3 studies, both the Pfizer-BioNTech and Moderna vaccines were found to be 95% effective in the early months after the vaccine. Put simply, If there were 100 people who would have gotten COVID, it prevented 95 of them from getting it, but it didnt prevent all 100, says Dr. Marks. It definitely provides some protection, but its not perfect.

    The good news is that early data found that those who did contract COVID-19 after receiving the vaccine did not develop a severe form of the disease. So even if it doesnt completely prevent illness, the study data shows that it does reduce the severity, says Dr. Marks.

    The third vaccine authorized in the United States also provides strong protection against severe illness and death. This vaccine, made by Johnson & Johnson, reported a 72% efficacy rate in preventing moderate to severe disease from COVID-19 in the U.S. and was 85 percent effective in preventing severe disease. Among the people who received the vaccine during clinical trials, after 28 days no one who contracted COVID-19 was hospitalized or died.

    Does The Covid Vaccine Affect Menstrual Cycles

    An evaluation into reports of menstrual disorders following the Covid-19 vaccines found that the number of reports of menstrual disorders and vaginal bleeding were low in relation to both the number of people who have received Covid-19 vaccines to date, and therefore did not support a link between changes to menstrual periods, related symptoms and Covid-19 vaccines.

    The MHRA continues to closely review reports of suspected side effects of menstrual disorders and unexpected vaginal bleeding, and anyone experiencing unusual changes to their periods following Covid-19 vaccination, should contact their doctor.

    What If You Test Positive On An At

    Those who test positive using an at-home test are asked to follow the latest CDC guidelines and communicate the results to their healthcare provider.

    Arwady has said that that process is not likely happening for every test, however.

    “All of those negatives realistically are not being reported,” Arwady said. “We’re not counting, you know, it’s a fiction that we’ve ever counted every COVID test.”

    Is Breast Pain Caused By Covid

    Why does your arm hurt after the COVID-19 vaccine?

    Breast pain isnt necessarily a symptom of COVID-19 or long-COVID, but you may have muscular or respiratory pain that you may feel in your breasts or chest.

    Breast pain is usually associated with COVID-19 vaccines and is a somewhat expected effect as the lymph nodes in your armpit launch an immune response to the vaccine.

    How Long Should You Wait To Be Vaccinated If Youve Had Covid

    The time frame that we recommend for being vaccinated after having a COVID-19 infection is as soon as youre out of quarantine, says Dr. Englund.

    There is one caveat, however.

    If youve received monoclonal antibodies, you must wait 90 days after recovering from COVID-19 to receive the vaccine. According to the Food and Drug Administration , monoclonal antibodies are proteins made in a laboratory that mimic your bodys immune response. Dr. Englund says some people might not need to be hospitalized for COVID-19, but might receive these antibodies from their doctor as an infusion treatment to help fight the virus.

    If youve had that monoclonal antibody, it is going to keep you from being able to develop a nice, robust response to the vaccine. So thats why we have to wait for 90 days until that monoclonal antibody has gotten out of your system.

    How Long Does Natural Immunity Last After A Covid

    Initially, researchers thought that natural immunity to COVID-19 only lasted for about 2 to 3 months before fading. There were even reports of people getting sick twice. But as experts have learned more about COVID-19, theyve found that immunity lasts much longer than that.

    One recent study found that natural immunity is still present in people up to 11 months after they were infected. Another small study from July 2020 noted that the memory cells of people who had COVID-19 are similar to those of people who were sick in the early 2000s with SARS . Because of this preliminary data, some experts think natural immunity to COVID-19 might last for several years.

    However, this may not be true for many people. There is recent research showing that not everyone that gets sick with COVID-19 is gaining immunity. In this study, 36% of people didnt become immune after recovering. This means they would be able to get sick with COVID-19 again.

    Serious Adverse Cases Reported

    CARM and Medsafe investigate reports of significant adverse events, including those with a fatal outcome.

    The aim of the investigation is for CARM and Medsafe to determine the likelihood the vaccine caused the reported events.

    For significant cases, including deaths, the COVID-19 Independent Safety Monitoring Board review the information supplied during the investigation and provide their view on the likely relationship of the reported events to vaccination.

    Causes of death are investigated and determined by the coroner not by CARM or Medsafe.
