Which Covid Shot Is Better

What The Cdc Is Saying

Which COVID-19 vaccine is better? (spoiler, theyre all good)

The Centers for Disease Control and Prevention has already issued its guidance on this matter. Back in August, the public health agency indicated in its vaccination guidelines that the administration of other vaccines and the COVID-19 shots may now be administered without regard or timing.

However, the CDC also pointed out at the time that healthcare personnel should consult with the current influenza vaccine recommendations issued by the Advisory Committee on Immunization Practices for specific vaccines, should they have people coming in asking for their flu shot after getting vaccinated against COVID-19.

Better Clinical Outcomes In Covid

Myocarditis is a condition that can lead to strokes or heart attacks. It is normally caused by infection with a virus, but it can be a reaction to a drug or inflammatory disease. In myocarditis, the myocardium becomes inflamed, reducing the hearts ability to pump blood and causing arrhythmias. Symptoms include chest pain, fluid build-up, and swelling of the lower body.

Are The Pfizer And Moderna Covid Vaccines Safe

In general, they appear to be quite safe and there were very few true severe problems noted in the study.

As of March 26, 2021, over 130 million doses of these vaccines have been administered. To date, the primary safety issue that has emerged is the possibility of severe allergic reactions. However, these are uncommon and only affect a handful of people per every million doses administered. For more on this, see this CDC page.

Now, its important to note that it was quite common for vaccine recipients to feel unwell after vaccination, especially after the second dose. The most common symptoms were fatigue and headache, and some people experienced fever, as well.

These are signs that the immune system is responding to the vaccine! So these should not be taken as a sign that the vaccine is dangerous, or not worthwhile.

Are Side Effects More Likely After The First Or Second Dose

With the two-shot vaccines, people are more likely to report side effects after their second dose, experts have said.

According to the CDC, 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,” the CDC states.

In trials of both the Moderna and Pfizer vaccines, more people experienced side effects after the second dose.

But that doesn’t mean that you shouldn’t get your second shot if you get side effects after your first, experts say.

When people receive that second dose, they are receiving the second booster to try and reach the maximum efficacy,” said Dr. Edward Cachay, infectious disease specialist at UCSD.

The CDC also noted that both shots are needed.

“The Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine both need 2 shots in order to get the most protection,” the CDC states. “You should get the 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.”

FACT: In April 2021, the CDC temporarily paused and then resumed use of the Johnson & Johnson vaccine. Read full story.

The Pfizer and Moderna COVID-19 vaccines can have side effects, but the vast majority are very short term not serious or dangerous. The vaccine developers report that some people experience pain where they were injected body aches headaches or fever, lasting for a day or two. These are signs that the vaccine is working to stimulate your immune system. If symptoms persist beyond two days, you should call your doctor.

If you have allergies especially severe ones that require you to carry an EpiPen discuss the COVID-19 vaccine with your doctor, who can assess your risk and provide more information about if and how you can get vaccinated safely.

Beyond 120 Days Moderna’s Shot Maintained Over 90% Effectiveness Against Hospitalization

byIan Ingram, Managing Editor, MedPage Today September 17, 2021

In terms of preventing COVID-related hospitalizations, the two-dose mRNA vaccines from Pfizer and Moderna offered the best protection upfront and over time, a case-control analysis involving data from 21 U.S. hospitals showed.

From March to August 2021, the vaccine effectiveness against COVID-19 hospitalizations landed at 93% for the Moderna vaccine, 88% for Pfizer’s, and 71% for Johnson & Johnson’s , reported Wesley Self, MD, of Vanderbilt University Medical Center in Nashville, Tennessee, and colleagues, writing in the Morbidity and Mortality Weekly Report.

After 120 days from the time of vaccination, however, Moderna’s VE against hospitalization only dipped to 92%, a non-significant decline, while Pfizer’s dropped to 77% .

“Differences in VE between the Moderna and Pfizer-BioNTech vaccine might be due to higher mRNA content in the Moderna vaccine, differences in timing between doses , or possible differences between groups that received each vaccine that were not accounted for in the analysis,” Self and co-authors suggested.

No data were shown for the J& J shot after 120 days due to the limited number of patients who received the vaccine, but the VE rate dipped to 68% for the single-dose vaccine after 28 days.

Overall, 20% were fully vaccinated with Pfizer’s vaccine, 12.7% with Moderna’s, and 3.1% with the J& J vaccine 64.0% were unvaccinated.

There have been reports of severe allergic reactions to the mRNA vaccines. Both the Pfizer and Moderna vaccines appear, on rare occasions, to trigger anaphylaxis, a severe and potentially life-threatening reaction. People who develop anaphylaxis must be treated with epinephrine the drug in EpiPens and may need to be hospitalized to ensure their airways remain open. The CDC says people should be monitored for 15 minutes after getting a Covid-19 shot, and 30 minutes if they have a history of severe allergies. J& J recently revealed that a single case of anaphylaxis has been reported in someone who received its vaccine.

It will take time to come up with a firm estimate of how frequently this side effect occurs. The most recent data from the CDC suggest that anaphylaxis occurs at a rate of about 2.5 cases per one million doses given of the Moderna vaccine, and 4.7 cases per million doses of the Pfizer. Many of the people who have developed anaphylaxis have a history of severe allergies and some have had previous episodes of anaphylaxis.

The mRNA vaccines carry a small risk of myocarditis and pericarditis, two types of heart inflammation that are most commonly seen soon after people receive their second shots, health officials have said. Men under 40 seem to be at highest risk, particularly those aged 12 to 17. Most cases reported have been mild and resolved.

Explain Potential Side Effects

Trust and open communication are so important, said Dr. Fryhofer. If you don’t tell people what to expect, physicians are going to be sorry because they’re going to get phone calls from patients about side effects.

That is because after getting a COVID-19 vaccine, most people are going to have some sort of side effect, she said. All three vaccines are going to cause a sore arm. You may feel a little bad, maybe a little tired, muscle aches, but it is so much better than getting COVIDand you do have to get that second dose.

You do expect to have more side effects with that second doseonly for Pfizer and Moderna, said Dr. Fryhofer, adding that if day one is the day you get vaccinated … most symptoms are going to be on day two, day three, possibly day four and then they’re usually gone. But for some people, they’re enough to make you not be able to go to work.

Additionally, with the J& J vaccine, its one dose and youre done, so you dont have to go for a second dose, she said. Its just the one time, but for our patients that means youre only going to have side effects one time.

For most people, not yet.

The questions of who needs booster shots and when should they get them is currently being looked at by the Australian Technical Advisory Group on Immunisation .

On Friday they announced people who are severely immunocompromised would be eligible for a booster shot from next week with Pfizer and Moderna the preferred vaccines.

They are yet to make any recommendations about third doses for the general population, so watch this space.

How About Out In The Real World

Until we wait for the results of head-to-head studies, theres much we can learn from how vaccines work in the general community, outside clinical trials. Real-world data tells us about vaccine effectiveness .

And the effectiveness of COVID vaccines can be compared in countries that have rolled out different vaccines to the same populations.

For instance, the latest data from the UK show both Pfizer and AstraZeneca vaccines have similar effectiveness. They both reliably prevent COVID-19 symptoms, hospitalisation and death, even after a single dose.

So what at first glance looks best according to efficacy results from clinical trials doesnt always translate to the real world.

Is It Safe To Get The Covid Vaccine When Pregnant

When Covid-19 vaccines first received emergency use authorisation in December, researchers knew little about how the jab could impact pregnant women. This was because pregnant women were excluded from initial clinical trials.

Several studies have since come to light and have shown positive preliminary results of the vaccines impact for pregnant women.

In one study, published in JAMA: The Journal of the American Medical Association earlier this month, Pfizer and Modernas vaccines sparked a robust immune response in pregnant and lactating women. The results also indicated that the vaccines protected the women against the novel virus.

Then a second study, published in the journal Obstetrics & Gynecology last week, revealed that there was no evidence the Pfizer or Moderna vaccine caused damage to the placenta in pregnant women.

Based on the current data available, the CDC and FDA have authorised the vaccines for anyone who is pregnant or planning to become pregnant. But the health agencies do recommend for women to consult with their healthcare provider if they are unsure about the potential effects of the vaccine.

You might want to have a conversation with your healthcare provider to help you decide whether to get vaccinated. While such a conversation might be helpful, it is not required before vaccination, CDC states on its website.

What Are The Covid Vaccine Side Effects

Some people notice side effects of the COVID-19 vaccine, such as pain or swelling where they got the vaccine. You may also get fever, muscle aches, chills, fatigue, headaches or a combination of these symptoms.

COVID-19 vaccine side effects may last about a day or two, and do not signify illness. These are signs that your immune system is responding and preparing to fight the coronavirus if you catch it. If symptoms persist, you should call your doctor.

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.

Moderna Vs Pfizer: Both Knockouts But One Seems To Have The Edge

A series of studies found that the Moderna vaccine seemed to be more protective as the months passed than the Pfizer-BioNTech vaccine. Heres why.

  • Read in app

It was a constant refrain from federal health officials after the coronavirus vaccines were authorized: These shots are all equally effective.

That has turned out not to be true.

Roughly 221 million doses of the Pfizer-BioNTech vaccine have been dispensed thus far in the United States, compared with about 150 million doses of Modernas vaccine. In a half-dozen studies published over the past few weeks, Modernas vaccine appeared to be more protective than the Pfizer-BioNTech vaccine in the months after immunization.

The latest such study, published on Wednesday in The New England Journal of Medicine, evaluated the real-world effectiveness of the vaccines at preventing symptomatic illness in about 5,000 health care workers in 25 states. The study found that the Pfizer-BioNTech vaccine had an effectiveness of 88.8 percent, compared with Modernas 96.3 percent.

Research published on Friday by the Centers for Disease Control and Prevention found that the efficacy of the Pfizer-BioNTech vaccine against hospitalization fell from 91 percent to 77 percent after a four-month period following the second shot. The Moderna vaccine showed no decline over the same period.

Its not appropriate for people who took Pfizer to be freaking out that they got an inferior vaccine.

See The Promise Of Mrna Vaccines

But more recent data have started to suggest a divergence in performance. For instance, a medRxiv preprint first published August 8 reports significantly fewer breakthrough infections among Moderna vaccine recipients than a similar cohort of participants that received Pfizer/BioNTechs.

The study analyzed data from people who underwent SARS-CoV-2 PCR testing at the Mayo Clinic Health System in Minnesota from January to July 2021. Within the population available, they matched patients of similar age, same sex, race, ethnicity, SARS-CoV-2 testing history, and date of vaccination from three different groups: those vaccinated with Moderna, those with Pfizer/BioNTech, and those unvaccinated. This matching exercise resulted in groups of between 21,000 and 25,000 individuals for each of the three vaccination categories.

The team then assessed how the mRNA vaccines protected individuals from COVID-19 and found that, while SARS-CoV-2 positive test results were rare among those vaccinated compared to the unvaccinated group , the Moderna cohort had significantly fewer of them. The estimated effectiveness of Moderna at preventing infections was 86 percent versus 76 percent in Pfizer/BioNTech, and when they expanded the data to four other US states, they saw a similar trend: the numbers altogether showed a two-fold risk reduction of breakthrough infections conferred by Modernas vaccine when compared to Pfizer/BioNTechs.

Do I Need The Vaccine If I Have Already Had Covid

Even if you had COVID-19, the CDC still recommends getting vaccinated. Thats because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19. Even if you have already recovered from COVID-19, it is possible although rare that you could be infected with the virus that causes COVID-19 again, the agency explains.

Have questions? Talk to your doctor.

Essentially, what a vaccine is doing is teaching the immune system how to handle something before you actually encounter the real thing so that, hopefully, when you do encounter the real thing, youre able to deal with it quickly and get rid of it.

Is It Safe To Not Wear A Mask After Getting The Covid Vaccine

WATCH: Which COVID vaccine is most effective?

For the most part, the CDC guidance states that fully vaccinated Americans are allowed to participate in normal activities without wearing a mask or social distancing.

“If you are fully vaccinated, you can start doing the things that you had stopped doing because of the pandemic,” Dr Walensky said during a White House press briefing last week when announcing the new guidance.

According to the CDC, vaccinated individuals no longer have to wear a mask for indoor and outdoor activities, including eating at a restaurant, participating in an exercise class, and attending an outdoor event like a concert.

This same guidance also applies to social distancing.

Previous guidance recommended for vaccinated individuals to wear a mask when indoors if they were around other people who have yet to receive a vaccine. But Dr Walensky said this would no longer be required.

“The science demonstrates that if you are fully vaccinated, you are protected. It is the people not vaccinated who are not protected,” she said.

“The science is also very clear about unvaccinated people: you remain at risk of mild or severe illness, of death, or of spreading the disease,” Dr Walensky added. “You should still mask, and you should get vaccinated right away.”

The CDC still requires all Americans to wear masks when on aeroplanes or other public transportation like trains and busses.

Covid Vaccine Hesitancy: Why People Don’t Want The Shot

Here’s what influences someone’s decision on whether to get the COVID-19 vaccine.

When the Food and Drug Administration authorized the first COVID-19 vaccine in December after an arduous year of disease, death and sheltering in place, many celebrated vaccination as a way out of a once-in-a-lifetime pandemic.

Others weren’t as enthusiastic. Some became fearful of a vaccine they thought was rushed or experimental, and they may have heard false statements about vaccines causing infertility or containing a microchip. Others drew comparisons to a thick history of medical gaslighting and abuse of people who look like them at the hands of the US government. Then there are those who value individual liberty above all else, and view vaccine promotion as an intrusion on personal choice. The push for COVID-19 booster shots throw more light on the discussion.

The US is no stranger to a vocal antivaccine movement, but the people who’ve chosen not to get a COVID-19 vaccine yet aren’t necessarily “antivax.” In fact, antivaxxers are likely a small number in the much quieter and much larger group who are vaccine hesitant.

“Television and the internet is going to highlight the people who are the most vehemently antivax, but if you take a look at it, a lot of the reasons people aren’t getting vaccinated is that they just don’t know,” says David Dunning, a professor of psychology at the University of Michigan who studies human misbelief.
