Which One Is The Best Covid Vaccine

What Is The Outlook For People With Guillain

How do you know which COVID vaccine is best?

The symptoms of GBS usually become most severe within four weeks of symptom onset, and then plateau. The majority of people recover, though the process may take weeks, months, or even years. Fortunately, most people who develop GBS are eventually able to return to their usual everyday and work-related activities without any significant residual physical impairment.

In some cases, even after recovery people may continue to experience weakness, pain, or fatigue, and require ongoing care. GBS is usually a once in a life-time occurrence, but a small number of people may experience a relapse.

What Are The Side Effects For Each Vaccine

According to Pfizer, about 3.8% of their clinical trial participants experienced fatigue as a side effect and 2% got a headache. The side effects remain similar among young adults and adolescents.

Younger teens receive the same vaccine dosage as adults and have reported the same side effects, mostly sore arms and flu-like fever, chills or aches that signal a revved-up immune system, particularly after the second dose.

Moderna says 9.7% of their participants felt fatigued and 4.5% got a headache.

Like Pfizer and Moderna’s COVID-19 vaccines,;the main side effects of the J&J shot;are pain at the injection site and flu-like fever, fatigue and headache. These side effects usually start within a day or two of getting the vaccine, according to the CDC.

But the;Johnson & Johnson;vaccine was recently paused by U.S. regulators as they investigated reports of potentially dangerous blood clots known as cerebral venous sinus thrombosis, or CVST, in a small number of recipients.

;The CDC and FDA said in April they were;investigating unusual clots in six women;that occurred 6 to 13 days after vaccination. All six cases were in women between the ages of 18 and 48. At the time, more than 6.8 million doses of the J&J vaccine had been administered in the U.S., the vast majority with no or mild side effects.

Ten days later, the agencies recommended;resuming use of the vaccine, stating the benefits of the inoculations outweighed their risks.

Organizations Get Different Types

Which vaccine a patient gets is dependent on the vaccination site. While one site may get Moderna, another might have Pfizer-BioNTech and then others might get J&Js COVID-19 vaccine.

My hospital has both the Moderna and the Pfizer, but the most important thing is whatever you get for the first dose, you have to get for the second dosetheres no mixing and matching, she said. You want to get the full series.

One big advantage of the Janssen vaccine is it only requires one dose, said Dr. Fryhofer. This means you dont have to come back for a second appointment. It also means only one set of vaccine side effects.

It Works Particularly Well In Young People

For younger, healthier people the convenience factor of a one-shot vaccine is not trivial.

People under 60 are generally not at great risk of major COVID-19 complications in the first place, and are more likely to struggle taking time off work, but it’s still imperative that they get vaccinated.;

They can do their part to combat the pandemic without having to schedule two vaccine appointments . With J&J’s shot, immune protection will become robust within a month, without having to go back in for a second booster.

Fortunately, this new vaccine works particularly well in the under-60 group too. In J&J’s trial, people under the age of 60 were well protected from serious infections: Only 58 out of more than 8,200 who were fully vaccinated got moderate to severe illness after their shot had time to take effect. In the similarly sized control group, 180 got moderate to severe COVID-19 infections.

J&J’s shot is also the only one that the FDA has reviewed, so far, that provides evidence that it helps stop people from spreading the virus asymptomatically. That is particularly useful for young people, as well as essential workers and people experiencing homelessness who may not be able to social distance, and already face more barriers getting access to vaccine or testing sites.

Q: Whats The Best Covid

Pfizers COVID

A:The one that you can get.

Clinical trials, like those for the new COVID-19 vaccines, generate a lot of numbers. But media reports about the results of these vaccine trials have focused almost entirely on a single data point efficacy. Is this a mistake?

Associate Medical Director Shawn Ferullo thinks so. Efficacy is far from the whole story, he says.

A vaccines efficacy is a measure of how effective it is at preventing any illness at all, however mild. Efficacy values for COVID-19 vaccines were computed by comparing the relative difference between the fraction of individuals in Phase Three vaccine and placebo groups who developed symptoms and tested positive.

If you look at efficacy numbers alone, the newly approved Johnson & Johnson vaccine, with a 66 percent efficacy rate, looks substantially worse than the Pfizer or Moderna vaccines, which both came in at around 95 percent, Ferullo acknowledges. But we need to look at these numbers in context. This context includes differences in how each clinical trial was conducted and a more practical view of what efficacy actually means.

So why get a flu shot? Because even if you get the flu after being vaccinated, youre likely to be a lot less sick than you would otherwise have been. By CDC calculations, the 20192020 flu vaccine, which had an efficacy value of just 45 percent, prevented an estimated 7.52 million illnesses, 3.69 million medical visits, 105,000 hospitalizations, and 6,300 deaths.

Is It Ok For Cancer Caregivers To Get The Vaccine

Some vaccines for other diseases contain changed versions of the live viruses that cause the diseases. These types of live virus vaccines typically are not recommended for cancer caregivers because they might have unwanted effects on cancer patients. However, the available COVID-19 vaccines do not contain these types of live viruses, so getting one of these vaccines does not put you at risk for passing COVID-19 on to the person youre caring for.

Its important to know that if you do get a COVID-19 vaccine and are later exposed to the virus, its not yet clear if the vaccine will prevent you from infecting someone else .

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 a health care provider about which precautions you still need to take.

People getting the vaccine might not feel well for a few days after each shot, so it might make sense to have someone else available to help with caregiving during this time.;

Covid Vaccines Still Effective Against Delta Variant

Senior health, science and environment reporter

Having two doses of Covid vaccine remains the best way to protect against the Delta variant, first identified in India and now dominant in the UK.

The Oxford-AstraZeneca jab, though initially less effective, offers the same high protection as the Pfizer-BioNTech after four to five months, the largest study of its kind suggests.

But neither is as effective as it is against the Alpha variant, responsible for most UK infections last winter.

There is insufficient data for Moderna.

But researchers believe it almost certainly at least as good as the others.

They analysed two and a half million tests results from 743,526 participants in the UKs Covid-19 household-infection survey led by Oxford University and the Office for National Statistics.

What To Watch Out For

How it works: As a carrier vaccine, it uses a different method to how mRNA vaccines function. The scientists concocted adenovirus as a shell that carries the genetic code on spike proteins going to the cells.;

With the combination of the code and the shell, you cant be sick. But once the code enters the cells, your cells will produce spike protein that will train your bodys immune system. This will then create the antibodies needed to protect your body against COVID-19 infection.;

Dosage: One-shot with protection fully effective two weeks after vaccination

Side effects: Fatigue, headache, injection site pain, chills, muscle pain, fever, and nausea. According to the FDA, It has milder side effects than that of Moderna and Pfizer. Theres no recorded allergic reaction in clinical trials.;

FDA cautions: Janssen vaccine has two label warnings from the FDA. Back in July, there were reports of cases of Guillain-Barre Syndrome, a neurological disorder.;

Though it was only on a small number of recipients, cases happened within 42 days after vaccination. The other label warning was due to very uncommon blood clots, and this also occurred in just a small number of vaccinated recipients.;

Effectiveness: While comparing the COVID vaccine,; it has an overall vaccine efficacy of 72% and 86% against other severe diseases. Last August, Johnson & Johnson announced that reliable data showed their booster shot at six months had a quick nine-fold boost in spike-binding antibodies.;

How Effective Are The Covid Vaccines Against The Delta Variant

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

Vaccine efficacy has been a main question as the delta variant continues to spread around the country.

Health experts have said that a majority of hospitalizations and deaths associated with the variant in recent months are almost entirely in unvaccinated individuals. The CDC has said the risk of infection is 8x higher in the unvaccinated than the vaccinated, and the risk of hospitalization or death is 25x higher.

But is one better than the other at protecting against breakthrough infections in vaccinated populations?

Researchers in Belgium directly compared the Pfizer and Moderna COVID-19 vaccines by testing the antibodies of 2,500 health care workers after two doses of both vaccines.

The study found the Moderna vaccine produced more than double the antibodies compared to Pfizer, but doctors urge caution.

Antibody level itself is interesting, but it doesnt necessarily lead to a significant difference in;the way the vaccine is performing, said Dr. Allison Arwady, Commissioner of the Chicago Department of Public Health.

Another study to consider when comparing vaccines is one from the Mayo Clinic earlier this month, which is awaiting a full review.

That study found the risk of suffering a;breakthrough COVID-19 infection;with the delta variant after being fully vaccinated with the Moderna vaccine may be much lower than the risk for those who received the Pfizer vaccine.;

Recommendations On Authorized Available Covid

These recommendations apply only to COVID-19 vaccines currently authorized for use in Canada . In considering these recommendations and for the purposes of publicly funded program implementation, provinces and territories may consider local programmatic factors and local epidemiology .

  • NACI preferentially recommends that a complete series with an mRNA COVID-19 vaccine should be offered to individuals in the authorized age group without contraindications to the vaccine.

  • NACI recommends that a viral vector COVID-19 vaccine may be offered to individuals in the authorized age group without contraindications to the vaccine to initiate a series when other authorized COVID-19 vaccines are contraindicated or inaccessible. Informed consent should include discussion about the risk and symptoms of VITT, as well as the need to seek immediate medical care should symptoms develop.
  • Refer to Table 5 for a summary of evidence and factors for jurisdictions to consider when implementing COVID-19 immunization programs.

    Summary of evidence and rationale:

    mRNA COVID-19 vaccines

    Informed consent for mRNA COVID-19 vaccines should include information about very rare reports of myocarditis or pericarditis in the week following an mRNA vaccine

    AstraZeneca COVID-19 vaccine

  • In clinical trials, the majority of local and systemic adverse events with the AstraZeneca COVID-19 vaccine were mild and transient and did not differ by dose administered or age.
  • Immunosuppressed persons

    How Do These Vaccines Work

    The Pfizer-BioNTech and AstraZeneca COVID-19 vaccines each work in different ways. The Pfizer-BioNTech vaccine uses mRNA technology, while the AstraZeneca vaccine uses an adenovirus vector.

    Below, well discuss the mechanisms used in each vaccine meant to help protect you from becoming ill with COVID-19.

    The Bottom Line With Covid

    Were trying to prevent:

    • COVID-19 infection
    • COVID-19 transmission
    • Severe COVID-19 cases that would require hospitalization or cause either long-term effects or death

    Every vaccine available right now is much more effective than no vaccine, and they all significantly reduce the likelihood of severe illness and death. This means that even on the chance that someone gets infected after receiving a COVID-19 vaccine, theyre less likely to spread it to others and less likely to end up in a hospitals intensive care unit.

    If we can get widespread immunization, we can decrease the community viral load , and the more people that are vaccinated, the better the vaccine works in a population.

    Getting as much of our population as possible immunized with any FDA-approved COVID-19 vaccine will help us reduce the threat of disease, control the pandemic and move forward with our lives.

    Will A Booster Shot Be Needed

    U.S. health authorities are now recommending an extra dose of the COVID-19 vaccine for all Americans eight months after they received their second dose of the Pfizer or Moderna shot.

    In a joint statement, the directors of the Centers for Disease Control and Prevention, Health and Human Services, the National Institute of Health and other top medical experts, outlined plans to begin administering booster shots later next month.

    The overall plan is pending a Food and Drug Administration evaluation of the safety and effectiveness of a third dose, the officials said.

    Those who were fully vaccinated earliest, which includes health care workers, nursing home residents and other older people, will be first in line to get a booster shot before they are available to the general public.

    What About Safety Of The Covid

    The FDA and other reviewers closely consider diverse populations included in the trials for safety purposes. The clinical trials for the first two COVID-19 vaccines included underrepresented minorities, older age groups, and people with conditions such as obesity, diabetes and heart and respiratory conditions.

    J&j Pause Shows System Is Working

    Among nearly 8 million doses of the J&J vaccine administered through April, the Food and Drug Administration and CDC reviewed data involving 15 reported cases in the U.S. of cerebral venous sinus thrombosis with thrombocytopenia in people receiving the vaccination. Most were in women between 18 and 49, with symptoms developing six to 13 days after vaccination.

    Overall, These adverse events appear to be extremely rare1.9 cases per millionbut COVID-19 vaccine safety is a top priority and health problems following vaccination are taken seriously. The reporting rate is higher for women under 50 at seven per 1 million and highest for women in their 30s at 11.8 per million. For women 50 and older, the reporting rate is less than one in 1 million.

    Since the pause was lifted April 23, the J&J Janssen vaccine is recommended for those 18 or older under an amended FDA emergency use authorization, which includes additional warnings and precautions, especially for women under 50.

    AMA President Susan R. Bailey, MD, commended ACIP for reaffirming its recommendation on the use of the Janssen COVID-19 vaccine for those 18 or older under the FDAs emergency use authorization. The population-level data presented during ACIPs meeting clearly demonstrates that the benefits of this approach outweigh the risks, she said.

    People Who Are Unsure About Getting Vaccinated Have Shown Enthusiasm For Johnson&johnson Because It’s One Dose

    Which COVID-19 vaccine is best for you?

    A Mar. 24 survey about vaccine hesitancy, administered by Survey Monkey, has revealed that among Americans who are “not sure” about getting vaccinated, more are willing to be injected with the one-shot Johnson&Johnson vaccine than the Pfizer-BioNTech and Moderna jabsboth of which require two doses.

    Another poll, which was done before the Johnson&Johnson vaccine obtained emergency use approval in the U.S., appears to back up Survey Monkey’s findings. The Kaiser Family Foundation published its KFF COVID-19 Vaccine Monitor on Feb. 26, and found that 26 percent of non-vaccinated Americans who were hesitant to get the jab were more likely to choose a vaccine requiring only one dose.

    “About a quarter of those who want to ‘wait and see’ before getting vaccinated say theyd be more likely to get a vaccine if only one dose was required ,” the analysis explained.

    How Are They Different

    Arguably one of the biggest difference between the three vaccines is the number of doses needed. The Johnson & Johnson vaccine requires just one dose, while both Pfizer’s and Moderna’s vaccines are two shots.

    The Pfizer-BioNTech and Moderna vaccines also differ from traditional vaccines in their use of mRNA. Instead of introducing a weakened or an inactivated germ into your body, this vaccine injects mRNA, the genetic material that our cells read to make proteins, into your upper arm muscle. It teaches your body how to make the protein that triggers antibody production so if the real virus later enters your body, your immune system will recognize it, according to the federal;Centers for Disease Control and Prevention.;
