Which Is Best Covid Vaccine

Side Effects And Safety

Which COVID-19 vaccine is the best? | DW News

The COVID-19 vaccines approved for use in the UK have met strict standards of safety, quality and effectiveness.

They can cause some side effects, but not everyone gets them.

Any side effects are usually mild and should not last longer than a week, such as:

  • a sore arm from the injection
  • feeling tired

What Is The Connection Between The Johnson & Johnson Covid

In July 2021, the FDA warned that the Johnson & Johnson COVID-19 vaccine may lead to a small but increased risk of Guillain-Barré syndrome . GBS is a disorder in which the body destroys its own nerve cells. It can lead to muscle weakness and sometimes paralysis, trouble breathing, or, rarely, death. The risk of developing GBS after receiving the J& J vaccine is very low, and benefits of vaccination still far outweigh the risks.

The FDAs warning was based on preliminary reports of about 100 cases of GBS that occurred in people who had received the J& J vaccine. To date, about 12.8 million people in the US have gotten the J& J vaccine. Most of the reported cases occurred in men ages 50 years and older, about two weeks after vaccination.

Almost all required hospitalization because GBS can affect the nerves to chest muscles and the diaphragm, making it difficult to breathe. Most people recover completely from GBS within a few months, but some never regain full strength.

Seek immediate medical attention if you experience any of the following symptoms after receiving the J& J COVID-19 vaccine:

  • weakness or tingling sensations, especially in the legs or arms, thats worsening and spreading to other parts of the body
  • difficulty walking
  • difficulty with facial movement, including speaking, chewing, or swallowing
  • double vision or inability to move eyes
  • difficulty with bladder control or bowel function.

Do I Still Need To Take Precautions If I Get The Covid

The COVID-19 vaccines are still being studied, as there are things we dont yet know about them. For example, researchers are still trying to determine how long the COVID-19 vaccines will help protect against the virus. And while the vaccines can clearly lower the risk of getting serious disease from COVID, its not yet clear how well they can prevent the spread of the virus to others.

For people who are fully vaccinated , the CDC has guidance on things you can now do , as well as what types of precautions you should still be taking. This guidance is being updated regularly, so check the CDC website for details. The CDC guidance may not apply if you have a weakened immune system , so its important to talk with your health care provider about which precautions you still need to take.

How Have The Covid

The urgency of the pandemic has meant that all available resources and efforts have been directed towards finding effective vaccines.

Globally, some COVID-19 vaccines were approved and administered just 12 months after the virus was discovered. Usually, development of a vaccine takes several years. Some of the reasons behind this rapid progress include:

  • The levels of funding and collaboration between vaccine developers and governments are greater than ever before. Planning began early, including investment in manufacturing facilities before a vaccine was even available.
  • Technology makes vaccine development faster than in the past. To develop a vaccine, scientists need to understand the viruss genetic code. New technology allowed researchers to quickly identify the genetic code of the COVID-19 virus soon after it emerged. This allowed scientists around the world to start designing and building vaccines.
  • Clinical trials progress more quickly if a disease is widespread, which is the case for COVID-19 in many countries. This means researchers can evaluate the effect of a vaccine on both unvaccinated and vaccinated groups much sooner than theyd be able with a rare disease.

What If I Have Breast Cancer Or A History Of Breast Cancer


Some people who get a COVID-19 vaccine might have swollen lymph nodes under the arm in which the injection was given . Because a swollen lymph node under the arm can also be a sign of breast cancer spread, most doctors recommend that people with breast cancer or a history of breast cancer get the injection in the arm on the opposite side of your breast cancer. For example, if your breast cancer/breast surgery was in the left breast, it is probably best to get the injection in the right arm. If you have had surgery on both breasts, its best to talk with your doctor about the best place on your body to get the injection.

Swollen lymph nodes after a vaccine injection might also have an effect on your mammogram results.

Safety Of A Moderna Booster Dose

Evidence of the safety of the Moderna booster COVID-19 vaccine is derived predominantly from clinical trials as well as limited post-implementation safety surveillance. The Moderna 50µg booster dose was safe and well tolerated among the 344 boosted participants, which included both 100µg and 50µg primary dose recipients.2 Rates of adverse events within the booster group were comparable to those observed after dose 2 of the primary series, with pain at the injection site the most common solicited local adverse event in both groups. Headache, fatigue and myalgia were reported as systemic adverse events equally across both groups. Axillary swelling or tenderness was the only adverse event more common in booster dose recipients, being reported in 21% of participants following a booster dose, compared with 14.2% of participants following their second primary dose.2 No grade 4 adverse events, or vaccine-related serious adverse events or deaths were reported in the booster trial.

Remind That Payments Not Required

If you go someplace and theyre wanting you to pay for the vaccine, that is a red flag, said Dr. Fryhofer. We have all paid for these vaccines, with our tax dollars, through Operation Warp Speed.

Now, you might be asked to show your insurance card, she added. The places that do administer vaccines are allowed to bill your insurance company for the administration fee, but you should not be paying.

I would also encourage patients to go on their department of health website and take a look at the forms that are being offered and read them, said Dr. Fryhofer. They’re going to have to read and understand them sooner or later, and that also can give you a feel as to whether or not this place is legitimate.

However, the best bet is to call your physician, she added.

What If My State Doesn’t Have An App That Lets Me Store My Card

If your state doesn’t have an iPhone or Android app that lets you store a copy of your vaccination record, there are other ways to keep it on your phone. What qualifies as valid proof, however, can vary by state, city, county or even individual business.

Some places may trust a photo of your physical vaccination card: Concert producer AEG Presents accepts a “physical copy of a COVID-19 Vaccination Record Card, a digital copy of such card or such other proof as is permitted locally.” But you definitely want to research first if your city, county or state does the same.

Along with many public schools, hundreds of private colleges are also requiring students and employees to be vaccinated: Seattle University, which requires students to be vaccinated to attend in-person classes, offers an online form to upload photos of the front and back of your vaccination card.

When in doubt, look for information on a business’s website or call the local health department and ask for clarification. It’s bound to save you time and lessen the risk of being turned away at the door.

Covovax And Corbevax: What We Know About India’s New Covid Vaccines

Top 8 Vaccines for Covid-19 | Comparison

India has approved two new vaccines, expanding its programme amid fears of a third wave fuelled by Omicron.

The new vaccines – Serum Institute of India’s Covovax and Biological E’s Corbevax – have both been authorised for “restricted use in emergency situation”.

India has now approved eight vaccines, three of which have been developed in India.

The country has so far given more than 1.4 billion doses.

The government aimed to vaccinate all Indians by the end of this year but is falling short of that target. About 62% of eligible adults have been fully vaccinated and more than 90% have received at least one jab since the beginning of the drive in January.

Prime Minister Narendra Modi said that India would begin administering booster shots – or “precaution doses” as he called them – to healthcare and frontline workers, and those above 60 with comorbidities from 10 January.

He said India would also begin vaccinating 15-18-year-olds from 3 January.

India’s daily caseload is around 6,000, but cases of the Omicron variant – about 653 now – have been rising in several states, prompting night curfews and a slew of other restrictions.

It’s unclear still if the newly approved vaccines will be deployed for booster shots, or if the government will insist on the third shot being the same as the first two.

Use Caution If You Are Allergic To This Ingredient

If you are allergic to polyethylene glycol or polysorbate, pay attention: “PEG and polysorbate are closely related to each other. PEG is an ingredient in the mRNA vaccines, and polysorbate is an ingredient in the J& J/Janssen vaccine. If you are allergic to PEG, you should not get an mRNA COVID-19 vaccine. Ask your doctor if you can get the J& J/Janssen vaccine.

If you are allergic to polysorbate, you should not get the J& J/Janssen COVID-19 vaccine. Ask your doctor if you can get an mRNA COVID-19 vaccine.”

Does Age Matter For Vaccinations

Pfizer’s vaccine is also currently the only vaccine authorized for emergency use in children as young as 5. Both Moderna and J& J’s vaccines can only be used on people 18 and older.

Both Pfizer and Moderna have also started studies in the U.S. surrounding the vaccine and children as young as 6 months.

Can I Choose Which Vaccine I Receive


All 3 vaccines are now being administered across Australia, however not all participating vaccination clinics, GPs and pharmacists will have all of the available vaccines to choose from.

  • The preferred vaccine for people aged 60 and over is the AstraZeneca vaccine.
  • The preferred vaccine for people aged 12 to 59 years is the Pfizer vaccine or the Moderna vaccine.
  • The preferred vaccine for people aged 5 to 11 years is the paediatric Pfizer vaccine.

However, adults aged 18 to 59 years can receive the AstraZeneca vaccine if they have weighed up the benefits and the risks, and provide informed consent. Talk to your doctor or immunisation provider to help inform your decision.

The Link Between Myocarditis And Covid

Myocarditis, an inflammation of the heart muscle, became a trending topic this spring when the Centers for Disease Control and Prevention reported that it is monitoring a small number of cases of heart inflammation that have arisen in young adults not long after mRNA COVID-19 vaccination. The side effect is considered important but uncommonarising in about 12.6 cases per million second doses administered. And now the Food and Drug Administration has announced it will place a warning on the mRNA vaccines. Its important to note that the vaccination is still recommended for everyone who is eligible.

What Do We Know About The Novavax Covid

The Novavax COVID-19 vaccine appears to be effective and safe, according to an analysis of phase 3 trial results released by the company in a press release. The trial found the vaccine to be 90% effective overall, and 100% effective against moderate and severe disease. The vaccine requires two doses, given three weeks apart, and may be stored using standard refrigeration.

The PREVENT-19 trial enrolled 29,960 participants, ages 18 years and older, across the US and Mexico. Two-thirds of the participants received the Novavax vaccine and one-third received a placebo. The trial was randomized, and observer-blinded, meaning the study participants and those evaluating the study endpoints did not know which participants received the vaccine.

Between January 25 and April 30, 2021, there were 77 confirmed cases of COVID-19 among the study participants. Of these, 63 occurred in the placebo group and 14 occurred in the vaccine group. All of the cases that occurred in the vaccine group were mild. Of those that occurred in the placebo group, 10 were moderate and four were severe. This translated to 100% efficacy against moderate and severe disease. The vaccine was 91% effective in people at high risk, which the study defined as people 65 years or older, with a medical condition that increased risk of severe COVID illness, or whose jobs increased their risk of exposure to COVID-19.

Side effects from the vaccine included arm pain at the injection site, fatigue, headache, and muscle pain.

The Road Ahead: Charting The Coronavirus Pandemic Over The Next 12 Months And Beyond

And even though the studies by Karikó and Weissman went unnoticed by some, they caught the attention of two key scientists one in the United States, another abroad who would later help found Moderna and Pfizers future partner, BioNTech.

Derrick Rossi, a native of Toronto who rooted for the Maple Leafs and sported a soul patch, was a 39-year-old postdoctoral fellow in stem cell biology at Stanford University in 2005 when he read the first paper. Not only did he recognize it as groundbreaking, he now says Karikó and Weissman deserve the Nobel Prize in chemistry.

If anyone asks me whom to vote for some day down the line, I would put them front and center, he said. That fundamental discovery is going to go into medicines that help the world.

But Rossi didnt have vaccines on his mind when he set out to build on their findings in 2007 as a new assistant professor at Harvard Medical School running his own lab.

He wondered whether modified messenger RNA might hold the key to obtaining something else researchers desperately wanted: a new source of embryonic stem cells.

In a feat of biological alchemy, embryonic stem cells can turn into any type of cell in the body. That gives them the potential to treat a dizzying array of conditions, from Parkinsons disease to spinal cord injuries.

But using those cells for research had created an ethical firestorm because they are harvested from discarded embryos.

Langer could barely contain his excitement when he got home to his wife.

Will My Childs Pediatrician Have The Vaccine

Which COVID Vaccine Booster is Best? Pfizer vs. Moderna vs. J. Johnson (Update 133)

It’s a good idea to call your childâs doctor to see if they have COVID-19 vaccines for younger children, Goza says.

âI think that is really where pediatricians will come in — talking about the vaccine, getting parents more comfortable about the vaccine, and then being able to give the vaccine,â she says.

But not all pediatricians will have vaccines right away, as the Pfizer shot requires special refrigeration, not to mention that pediatrics offices are typically busy this time of year anyway.

The pharmacy is another great option, says Eric Ascher, DO, a family medicine doctor at Lenox Hill Hospital in New York City.

âPharmacists are well-trained in vaccine administration,â he says.

âThey are also well-trained if in the very rare event something happens. In fact, in the hospital, when a patient has a medication or vaccine side effect, the pharmacy team is the first group bedside, alongside the physician, to help treat the patient.â

If parents are hesitant to take their 5- to 11-year-old to a pharmacy to get a COVID-19 vaccine, they should raise any questions or concerns with their pharmacist, says Danielle M. Zerr, MD, division chief of pediatric infectious disease at the University of Washington..

âWhatâs key is the vaccinatorâs experience in administering vaccines to children,â she says. âThis is a question that parents can ask of the pharmacy.â

“We found a really good immune response across the board…, in fact, higher than the threshold set by Oxford-AstraZeneca vaccine two doses,” Matthew Snape, the Oxford professor behind the trial dubbed Com-COV2, told Reuters.

The findings supporting flexible dosing will offer some hope to poor and middle income countries which may need to combine different brands between first and second shots if supplies run low or become unstable.

“I think the data from this study will be especially interesting and valuable to low- and middle-income countries where they’re still rolling out the first two doses of vaccines,” Snape said.

“We’re showing…you don’t have to stick rigidly to receiving the same vaccine for a second dose…and that if the programme will be delivered more quickly by using multiple vaccines, then it is okay to do so.”

If the AstraZeneca-Oxford vaccine is followed by a Moderna or Novavax shot, higher antibodies and T-cell responses were induced versus two doses of AstraZeneca-Oxford, according to researchers at the University of Oxford.

The study of 1,070 volunteers also found that a dose of the Pfizer-BioNTech , vaccine followed by a Moderna shot was better than two doses of the standard Pfizer-BioNTech course.

No safety concerns were raised, according to the Oxford University study published in the Lancet medical journal.
