Are The Covid Vaccines Safe

Are Mrna Vaccines Safe

Are coronavirus vaccines safe?

All COVID-19 vaccines have to meet the same rigorous FDA safety standards as any other vaccine.

You may be wondering then, how these COVID-19 vaccines were developed so quickly compared to the vaccines of the past, which took years to create. The speed happened on the front end in the development of the vaccines. Because of massive public and private funding, many of the financial hurdles that can delay research projects were removed. But the testing and approval processes were no different than those for other vaccines in the past.

The reported side effects of the mRNA vaccines were temporary symptoms such as fever and muscle aches, similar to what some people experience after getting other vaccines. Most common side effects of a vaccine are identified in studies before the vaccine is licensed. In rare cases, adverse side effects may not be detected in these studies, which is why the U.S. vaccine safety system continuously monitors for side effects after a vaccine is licensed.

In addition to the standard safety monitoring systems, there is an added layer of scrutiny for the COVID-19 vaccines to give the Centers for Disease Control and Prevention real-time information as Americans get vaccinated. The CDC has developed V-safe, a smartphone-based health checker that allows people to report any adverse side effects after getting the vaccine.

Who Approves Vaccines Or Treatments

Approval is only given in the UK if the regulator is happy that a vaccine is safe and effective.

Checks continue after approval to make sure there are no further side effects or long-term risks.

Independent experts on the Joint Committee on Vaccination and Immunisation decide how best to use a vaccine and who should get it.

Rare Reactions That Have Been Reported

As with all vaccines, there’s a chance that there will be a serious side effect. All side effect reports, including the rare reactions below, continue to be monitored closely by:

  • Health Canada
  • the Public Health Agency of Canada
  • provincial and territorial health authorities
  • the manufacturers

Health Canada is:

  • working closely with the manufacturers to ensure the labelling reflects relevant information
  • continuing to monitor these reports and is working with international regulators to review information as it becomes available

What About Cancer Patients With Severely Weakened Immune Systems

We believe the COVID-19 vaccines will be safe for patients with severely weakened immune systems, for example, as the result of a stem cell transplant. But these vaccines may not work as well during certain phases of cancer treatment. You should discuss the timing of getting a COVID-19 vaccine, as well as the risks and benefits, with your MSK care team.

Do I Still Have To Wear A Mask And Continue Covid

Studies suggest AstraZeneca COVID

The CDC continues to monitor the spread of COVID-19 and makes recommendations for wearing face masks, both for those who are fully vaccinated as well as those who are not fully vaccinated.

The CDC also recommends that masks and physical distancing are required when going to the doctors office, hospitals or long-term care facilities, including all Johns Hopkins hospitals, care centers and offices.

Johns Hopkins Medicines current mask safety guidelines have not changed, and we still require all individuals to wear masks inside all of our facilities.

Which Vaccines Have Been Authorised And For Which Age Groups

Most countries that have begun rolling out COVID-19 vaccines to 12- to 17-year-olds are using the Pfizer/BioNTech vaccine, although some European countries are also using the Moderna vaccine. The United Arab Emirates has authorised the Sinopharm vaccine, and Indonesia the Sinovac vaccine for 12- to 17-year-olds. China has approved emergency use of Sinovacs vaccine for children aged 3 to 17.

How Safe And Effective Has It Been Overseas

Australia has around 2.3 million children aged 5-11. So we can look to the real-world experience of the Pfizer vaccine in the US to see what we can expect.

More than 5 million US children aged 5-11 have had one dose and more than 2 million have had a second dose.

One potential concern authorities are watching out for is the risk of heart inflammation, called myocarditis. This is a rare side effect after the second dose in young males aged 12-17, with an estimated risk of around ten cases per 100,000.

No cases of myocarditis, or the related condition pericarditis, were reported in the clinical trial of 5-11 year olds.

No data is yet available on the real world effectiveness of the vaccine to protect against hospitalisation or infection in children aged 5-11, however this will emerge.

What Is The Fast

Scientists hope to tweak coronavirus vaccines to ensure they continue to offer high protection as new variants of the disease emerge.

The UK’s drug regulator says new vaccines can be fast-tracked for approval if needed.

No corners will be cut, with safety paramount.

But lengthy clinical trials with thousands of volunteers will not be needed.

Instead, data from existing studies and ongoing real-world use could be used.

Can I Mix And Match The First Two Shots

COVID-19 Vaccines: How Do We Know They Are Safe? | April 2, 2021

No, the CDC’s statement on mixing COVID-19 vaccines only applies to boosters. As of now, the FDA has only authorized a mixed-series booster, meaning the first coronavirus vaccine series must be one dose of Johnson & Johnson or two doses of Moderna or Pfizer.

Once the mixed-series boosters start rolling out to Americans in greater numbers, there will be more data on the safety and effectiveness of a mixed COVID-19 series. Although it might be too early to hope, this might mean that data on mixing for boosters will inform decisions on primary coronavirus vaccine series being used together, making it easier to reach underserved communities, and possibly reducing health care and vaccine inequity.

Will The Vaccine Give Me Side Effects

Vaccines do not give you a disease. Instead, they teach your body’s immune system to recognise and fight the infection they have been designed to protect against.

Some people do experience mild to moderate symptoms after being vaccinated. This is not the disease itself, but the body’s response to the vaccine.

Common reactions that may affect more than one in 10 people and typically get better within days include chills, tiredness and aching muscles.

Approving Vaccines In Canada

and regulations. They must meet the regulatory requirements for safety, efficacy and quality before they can be approved for use and distribution in Canada. The federal government is responsible for approving vaccines.

Before authorizing a vaccine, Health Canada assesses the:

  • scientific and clinical evidence including results of clinical trials to determine if a vaccine product is safe, effective and manufactured to the highest quality
  • safety and efficacy of the vaccine to determine that there are no concerns, the vaccine can trigger an adequate immune response to protect against disease and the benefits outweigh the risks
  • manufacturing process to make sure the manufacturer can carry out the necessary quality controls for the vaccine

If there is not enough evidence to support the manufacturers safety, effectiveness or quality claims:

  • Health Canada will not authorize the vaccine
  • the product cannot be sold in Canada

Who Should Not Get The Vaccine

You should not get the vaccine if you have:

  • symptoms of COVID-19covid 19
  • another acute disease, such as strep throat, flu or pneumonia
  • received another vaccine in the past 14 days

Speak with your doctor or health care provider before booking an appointment if you or the person you are booking for:

If the virus reappears, your immune system will recognize the antigens and attack them before the disease can develop and cause sickness.

In addition to the antigens, vaccines can also include:

  • adjuvants help boost the bodys response to the vaccine
  • antibiotics prevent contamination during the manufacturing process
  • preservatives and stabilizers keep the vaccine stable, effective and safe when its being made, shipped and stored

Can I Do Anything Ahead Of Time To Reduce Any Side Effects From The Vaccine


Its important that you do not take over-the-counter drugs before getting your vaccine because there are concerns that some pain-relieving drugs may interfere with the immune response to the vaccine. It is also unclear if taking medication ahead of time actually works to reduce post-vaccine symptoms. You should wait until after being vaccinated to see how you feel. If you do experience side effects, it is OK to take an over-the-counter drug like Advil or Tylenol to lower a fever, reduce chills, or relieve a headache or body aches.

The Vaccine Shows No Major Side Effects

Just like their older counterparts, some children in the study experienced mild side effects, such as pain at the injection site, fatigue and headache. Those side effects usually lasted a day or two.

A tiny percentage of people in older age groups, mostly male adolescents and young men, have developed myocarditis or pericarditis inflammation of the heart muscle or heart lining that usually resolves on its own after vaccination. Myocarditis patients typically recover quickly and don’t have lasting effects on their heart.

The benefits of COVID-19 vaccination outweigh the risks of myocarditis after vaccination. The risk of myocarditis is significantly higher after coronavirus infection itself, compared to vaccination.

None of the children involved in Pfizer’s clinical trial for the 5-11 age group developed myocarditis or pericarditis.

Are Mrna Vaccines Effective

The efficacy of vaccines is proven through phases of tests on increasingly large numbers of human volunteers. The Phase 1 trial usually includes 20-100 volunteers. If no serious side effects are reported, the trial moves to Phase 2, which typically involves several hundred volunteers and further refines the correct dosage. If no serious side effects emerge, its on to Phase 3, which includes thousands of volunteers split into two groups one that receives the drug and the other that receives a placebo.

In Phase 3, the Pfizer-BioNTech trial for adults included more than 44,000 people, and the Moderna Phase 3 trial had more than 30,000. The volunteers, initially all adults, represented a range of races and ethnicities. The researchers kept track of how many people both those who received the vaccine and the placebo group came down with COVID-19.

Both vaccines proved to be more than 90% effective in preventing symptomatic cases of COVID-19. The FDA reviewed the data from both trials to ensure it was accurate.

What isnt known yet is how long the vaccine protects you from COVID-19. It also isnt certain whether vaccinated people can still carry and spread the virus. Thats why its important to continue to wear your mask and practice physical distancing after being vaccinated.

Are You Giving The Johnson & Johnson Covid

On Friday, April 23, 2021, the Food and Drug Administration and the Centers for Disease Control and Prevention lifted the temporary pause of the Johnson & Johnson COVID-19 vaccine, allowing vaccine providers to resume administration of this vaccine.

UI Health Care is following guidance from the Food and Drug Administration and the Centers for Disease Control and Prevention and is resuming administration of the Johnson & Johnson COVID-19 vaccine.

Six Countries In The Americas Are In Danger Of Missing A Year

Are the Coronavirus (COVID-19) Vaccines Safe and Effective?

As many as six countries in the Americas are struggling so much with coronavirus vaccinations that they may fall short of a global target of having 40 percent of their populations protected by the end of the year, the Pan American Health Organization warned on Wednesday.

The organizations parent agency, the World Health Organization, set the goal, but for many poorer countries it has been difficult to attain because of inequities in global vaccine distribution.

Dr. Carissa F. Etienne, director of the Pan American Health Organization, told reporters on Wednesday that overall, 55 percent of people in Latin America and the Caribbean had been fully inoculated so far, but that 20 countries in the region had not yet reached the 40 percent threshold. The agency expects many of them to get there by Dec. 31, Dr. Etienne said, but six countries remain far behind.

Dr. Jarbas Barbosa, assistant director of the Pan American Health Organization, identified those countries as Haiti, Jamaica, St. Vincent and the Grenadines, Guatemala, St. Lucia and Grenada. He said the agency was working with each of them to try to improve vaccination rates.

The most concerning situation is Haiti, Dr. Barbosa said, citing the earthquake that struck there in August and the political crisis touched off in July by the assassination of Haitis prime minister. Those events have contributed to keeping vaccine coverage in Haiti very low, he said.

What Are Children Going To Get

In the same way that pharmaceutical companies raced to get the vaccine approved for adults, those companies have carried out trials to see if their vaccines are safe and effective in adolescents and children.

Speaking at an Independent SAGE briefing on November 5, 2021, Prof. Deenan Pillay a professor of virology at University College London in the United Kingdom said:

There have been a number of trials. We are always concerned about the untoward effect of all medicines in children, and, of course, we cant just extrapolate from data that from adults to children. We have got to wait to ensure there is safety in children. And now that has happened.

So far, mRNA vaccines from Pfizer and Moderna have received approval in the U.S. for children over 12 years of age, with the Pfizer vaccine approved for 512-year-olds at the end of October 2021.

The European Medicines Agency announced that it would start investigating the safety of the vaccine in that age group on October 18, 2021.

Most countries offering vaccination to those over 12 years of age are offering the Pfizer or Moderna vaccine, Reuters recently reported. A single dose of the Pfizer vaccine is available for those over 12 years old in the U.K., where the Moderna vaccine also has approval for this age group.

Pfizer has plans to trial the vaccine in children aged 6 months to 5 years, and Moderna has ongoing trials to test the safety and efficacy of vaccines in children under 12 years old.

Can Any Of The Vaccines Give Me Covid

None of these vaccines contain the virus, so they cant give you COVID-19. These vaccines contain genetic instructions that allow your own cells to make one of the virus proteins. Your immune system reacts to this protein to make antibodies and other immune cells that can recognize and fight COVID-19 if you do get exposed.

Theres Now A Formal Name And Help For Prolonged Grief

A year after her mother died from Covid, Fiana Garza Tulip held a small memorial service on a Texas beach that her family had visited countless times when she was a child. As she and her brother dropped a wreath of yellow roses into the waves, she expected to cry. But the tears did not come. She felt only guilt for appearing to be unmoved, heartless even.

Ms. Garza Tulip, 41, had endured so many losses two miscarriages, and the virus taking her mother, uncle and great-aunt. It also debilitated her father. I think the one thing I miss the most is feeling anything, she said recently of life after the series of tragedies.

She had thought the lack of emotion meant she was not grieving, unaware that numbness can be a symptom of grief. When a therapist diagnosed her with prolonged grief disorder, or P.G.D., a newly recognized condition, Ms. Garza Tulip, who lives in New Jersey, was relieved that her suffering had a name.

Recently added to the upcoming revision of the Diagnostic and Statistical Manual of Mental Disorders, or D.S.M., prolonged grief disorder leaves people feeling stuck in an endless cycle of mourning that can last for years or even decades, severely impairing daily life, relationships and job performance.

This is about a lost relationship that was central to who you are, said Holly Prigerson, co-director of the Center for Research on End-of-Life Care at Weill Cornell Medicine in New York. Now this person is gone, its I dont know who I am anymore.

What If I’ve Already Had Covid

Moderna COVID

People will still be offered the jab even if they have had Covid-19 in the past.

That’s because natural immunity may not be long-lived and immunisation could offer more protection.

Guidance says there are no safety concerns about giving jabs to people with “long” Covid either. But people who are currently unwell with Covid-19 should not receive the vaccine until they have recovered.

Heres What You Need To Know:

More than 200 million Americans over 60 percent of the population have been fully vaccinated against the coronavirus.

The United States crossed that milestone as the threat of the Omicron variant spurred a flurry of jabs in recent days, though the daily rate remains far below its peak in April. And the U.S. lags significantly behind several other countries, which have inoculated over 80 percent of their populations.

Providers are administering about 1.78 million doses per day on average, including first, second and additional doses, about a 47 percent decrease from the peak of 3.38 million reported on April 13, according to federal data.

The United States remains far behind not only developed countries like Singapore and Portugal, which will soon have vaccinated 90 percent of their populations, but developing nations like Cambodia , according to Our World in Data.

Even before the arrival of Omicron, cases and hospitalizations were on the rise in the U.S. as the weather grew colder in much of the country and the highly contagious Delta variant remained a threat. Daily cases are averaging over 120,000 and more than 55,000 patients are hospitalized nationwide, far fewer than in September but an increase of more than 15 percent over the last two weeks. Hospitals have been overstretched from upstate New York to New Mexico.

Many questions remain about Omicron.

Broad mandates by President Biden that had helped boost vaccination rateshave been put on hold by courts.
