Why Is The Second Covid Vaccine Worse

Are The Side Effects Worse After The Second Dose

Understanding COVID-19 vaccine side effects, why second dose could feel worse

Theres a good chance the side effects following your second shot are worse than those you experienced after your first, according to the CDC.

Thats because your body, through the memory immune cells it developed, recognizes the vaccine, Moss said. The part of the immune system thats causing the local reactions near the injection site, like soreness or redness, or the more systemic reactions, the fever and fatigue, they are more reactive after the second dose and its because your immune system responding more aggressively.

However, you shouldnt worry. The CDC says side effects like pain, redness and swelling near the injection site and tiredness, muscle pain, fever and nausea throughout the rest of your body are signs it is building protection. Those symptoms should abate within a few days, and you can take over-the-counter pain relievers like ibuprofen and acetaminophen to counter the discomfort after receiving your shot.

Are The Side Effects Of The Second Covid Vaccine Worse Than The First Your Coronavirus Vaccination Questions Answered

Michael Berry got his first dose of the coronavirus vaccine at a big clinic in Rockville run by the Montgomery County Department of Health. It was March 9, and the 72-year-old said he received a shot of the immunization made by Moderna.

A Silver Spring resident, Berry said he was told to expect a series of emails when it was time for him to schedule an appointment for his second dose.

But April 9 marked four weeks to the day, and Berry said no such email arrived.

He called around but got caught in a cycle of recordings, dropped calls and telephone trees. Anxious to achieve maximum immunity considering his age and existing health conditions, Berry even wrote his primary doctor. He was concerned about the consequences he didnt know of receiving the second dose late and what would happen if he can get a different brand than the original immunization.

Im a little frustrated and distressed about the whole thing, Berry said, and worried.

Berrys experience echoed that of other Marylanders concerned about protecting themselves. So The Baltimore Sun sought out to answers to some of the most frequent second dose questions. Heres what we found:

What If You Miss Your Second Covid Shot

The Pfizer vaccine has a 21-day window between shots, while the Moderna vaccine has a 28-day window. While you shouldnt receive a second dose before these dates, there isnt a cutoff date for your second shot

Generally, you should get it as soon as possible if you happen to miss your second dose. Officially, the CDC says doses can be given up to six weeks apart. But even if you receive the shot weeks, or even months, afterward, it will still provide immunity. If the second dose is administered beyond six weeks, you dont need to restart the series of vaccines.

Whatever you do, make it a priority to get your second COVID-19 vaccine. The old adage better late than never applies here.

/7what To Expect With The Second Covid

Getting the second jab of your coronavirus jab is essential to secure full immunization against the viral pathogen. With most vaccines available as 2-dose regimes, it’s important to get the second jab as and when you can.

The first dose of the vaccine kicks in necessary inflammatory reactions and starts building antibodies. With the second dose, the memory cells come into action. As it works to garner higher strengthening antibodies, it remembers the infection from the first time around, and thus, the immune system could be more robust and lead to stronger, more intense side-effects. This is primarily the reason why the second dose could be stronger and cause more side-effects than the first time around, despite getting the same shot as the first time around.

Does One Vaccine Cause More Side Effects Than The Other

Why many Canadians feel stuck in

According to Pfizer, about 3.8% of their clinical trial participants experienced fatigue as a side effect and 2% got a headache.;

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

But experts say data shows the two are similar and that side effects depend more on the person than shot itself and cautioned against trying to make a decision between the two vaccines based on side effects.

Q: Are The Side Effects Worse If Youve Already Had Covid

Research and anecdotal reports suggest that people with a previously diagnosed Covid-19 infection may have a stronger reaction and more side effects after their first dose of vaccine compared to those who were never infected with the virus. A strong reaction to your first dose of vaccine also might be a sign that you were previously infected, even if you werent aware of it.

If you previously tested positive for Covid-19 or had a positive antibody blood test, be prepared for a stronger reaction to your first dose, and consider scheduling a few days off work just in case. Not only will it be more comfortable to stay home and recover in bed, the vaccine side effects can resemble the symptoms of Covid-19, and your co-workers wont want to be near you anyway.

Health Experts Say Those Previously Infected With Covid

BISMARCK, N.D. – Doctors are encouraging everyone to get vaccinated against COVID-19 even if youve already had the virus. However, experts say, be prepared for more intense side effects.

In a study posted by medRxiv , researchers report many people who had previously been infected with the virus reported flu-like symptoms after their first dose. Although these findings could mean some discomfort, they also provide insight into how future vaccine doses are determined.

Rachel Barth tested positive for COVID-19 in November.

I was very sick for like 10 days– super congested, headaches, lost my taste and smell, was very tired, very rundown, said Barth, Mandan resident and COVID survivor.

So, she hopped on the chance to make her vaccination appointment as soon as she was eligible.

I never want to get it again. I want to make sure Im not giving it to people around me, said Barth.

New findings show people like Barth who have previously had COVID might be at a higher risk of more intense reactions to the vaccine due to their antibodies attacking the known spike proteins.

The immune system, when you have COVID, creates antibodies. Those antibodies are there to help fight infection. So, when you get the COVID jab, youre introducing viral particles back into an immune system that already recognizes COVID. So, your bodys just doing what it wants to do naturally– and thats fight the infection, said CHI St. Alexius Medical Director Dr. JPatrick Fahn.

How Should You Prepare For Your Second Shot

You can expect to receive the second dose three to four weeks after the first. The Centers for Disease Control and Prevention recommends spacing Pfizer-BioNTech doses 21 days apart and Moderna doses 28 days apart in accordance with company directives.

If youre concerned about side effects, you can take preliminary steps to reduce their potential severity, such as resting and ensuring that any existing medical conditions are well controlled. While you should make sure that you have ibuprofen, aspirin, acetaminophen, or antihistamines on hand as well, Wen strongly recommends against medicating beforehand.

There is some mixed data about this, but some people believe that if you blunt your response by taking Tylenol or ibuprofen, it may reduce the effectiveness of the vaccine,” she says. “Now, I’d say that that is quite controversial, and there isn’t definitive evidence about this.”

However, its probably better to play it safe. Some studies have found that over-the-counter pain relievers can interfere with the immune response provoked by vaccines, including the COVID-19 vaccine.

One such study linked the use of nonsteroidal anti-inflammatory drugs , including ibuprofen, to a decrease in cytokine activity and antibody production. These findings, the authors wrote, raise the possibility that NSAIDs may alter the immune response to SARS-CoV-2 vaccination.

What About Other Uncommon But Potential Side Effects

Recent reports have brought to light some other unexpected, but so far not serious, side effects that could be related to the vaccines, experts say.

As more and more Americans receive their first or second doses of the Pfizer or Moderna COVID vaccines every single day, some people who menstruate are reporting changes to their periods after getting vaccinated.

Health experts have noted that menstrual changes have been documented in recent months outside of vaccinations as well.

Even without contracting COVID or getting vaccinated, menstrual changes have been reported possibly stemming from the overall pandemic environment itself. A;Washington Post report from August;found that several gynecologists “confirmed that many of their patients are reporting skipped periods or have noticed increases or decreases in cycle length, blood volume and level of menstrual-related pain.”

There have also been reports of what’s known as “COVID arm,” a term used to describe delayed skin reactions such as rashes, which appear days after injection.

The skin reactions gained attention when a letter was published in the;New England Journal of Medicine;earlier this month detailing some patients who experienced varying degrees of arm rashes following their first dose of the Moderna vaccine.

The CDC acknowledged reports “that some people have experienced a red, itchy, swollen, or painful rash where they got the shot,” which it identified as “COVID arm.”

It Takes Time For The Vaccination To Provide Immunity

Clinical studies indicate that the vaccination may provide some protection around 12 days after the first dose is given, but you must get both doses in order to achieve full protection. When both doses are administered, the vaccine is more than 90% effective at preventing COVID-19 infection.

On May 13, the CDC stated that people who are fully vaccinated no longer need to wear masks or maintain social distancing in most situations. However, the CDC also noted that people with weakened immune conditions, such as cancer, should talk to their healthcare provider about the need for protective measures even after vaccination. Therefore, to protect our patients from COVID-19, MSK requires that all staff, patients, and visitors must continue to wear masks while at MSK. This requirement includes people who are fully vaccinated.

Q: Ive Heard The Covid Vaccine Side Effects Especially After The Second Dose Can Be Really Bad Should I Be Worried

Short-lived side effects like fatigue, headache, muscle aches and fever are more common after the second dose of both the Pfizer-BioNTech and the Moderna vaccines, which each require two shots. Patients who experience unpleasant side effects after the second dose often describe feeling as if they have a bad flu and use phrases like it flattened me or I was useless for two days. During vaccine studies, patients were advised to schedule a few days off work after the second dose just in case they needed to spend a day or two in bed.

Data collected from v-safe, the smartphone-based tool everyone is encouraged to use to track side effects after vaccination, also show an increase in reported side effects after the second dose. For instance, about 29 percent of people reported fatigue after the first Pfizer-BioNTech shot, but that jumped to 50 percent after the second dose. Muscle pain rose from 17 percent after the first shot to 42 percent after the second. While only about 7 percent of people got chills and fever after the first dose, that increased to about 26 percent after the second dose.

The New York Times interviewed several dozen of the newly vaccinated in the days afterward. They recounted a wide spectrum of responses, from no reaction at all to symptoms like uncontrolled shivering and brain fog. While these experiences arent pleasant, they are a sign that your own immune system is mounting a potent response to the vaccine.

Q: What About Taking A Pain Reliever After The Shot

Someone on Instagram talking about how Covid

Its OK to treat side effects with a pain reliever, said Dr. Offit, but if you dont really need one, dont take it.

While most experts agree its safe to take a pain reliever to relieve discomfort after you get vaccinated, they advise against taking it after the shot as a preventive or if your symptoms are manageable without it. The concern with taking an unnecessary pain reliever is that it could blunt some of the effects of the vaccine.

Understand;Vaccine and Mask Mandates in the U.S.

During the Moderna trial, about 26 percent of people took acetaminophen to relieve side effects, and the overall efficacy of the vaccine still was 94 percent.

What If You Don’t Get The Second Covid Shot

In April, a New York Times article made waves around the country, noting how 8 percent werent receiving their second vaccination. By mid-June, those figures increased to 12 percent of Americans who werent getting a second dose, according to CDC data.

As of early July, more than 181 million Americans received at least one COVID-19 vaccine dose, and more than 155 million are fully vaccinated. In Oklahoma, there have been more than 3.2 million doses administered 1.7 million Oklahomans have received at least one dose and 1.5 million people are fully vaccinated.

On the surface, the numbers are headed in a positive direction as a majority of Americans are receiving their second dose. However, there is still a faction of the country using a one-and-done approach to the vaccine.

Pennsylvania is among the worst offenders in the country, with more than 16 percent of residents failing to receive their second dose, according to the Philadelphia Inquirer.

Why does this matter? A CDC study showed adults 65 and older who received both doses were 94 percent less likely to be hospitalized with COVID-19 compared to just 64 percent less likely for those who were partially vaccinated.;

Put simply: Not receiving the second vaccine increases your risk of contracting COVID-19. An additional study from March showed one vaccine dose limited risk of infection by 80 percent compared to 90 percent with two doses.

Protection Against New Variants

This amplification not only makes the immune response more effective, but also helps it last longer.

“Let’s say you need an antibody level of 100 to fight this off. We are, with some of these vaccines, inducing antibody levels of 3,000 and 4,000. So we really are developing just a huge antibody response,” Poland said.

“That accounts for some of these off-target effects, but there’s also a positive to that,” he continued. “Antibody wanes over time, so the higher you start out, the longer you have a protective level of antibody present.”

“As you get to that level of antibody, you get a greater breadth of response. By breadth of response, we mean it covers not only the wild-type and currently circulating virus, but also the variants that we see circulating,” Fauci said during a Monday media briefing of the White House COVID-19 Response Team. “It’s not just a matter of potency. It’s a matter of the breadth of what you can cover.”

One interesting fact to keep in mind, Poland said, is that — because people’s immune response tends to wind down as they age — younger and middle-aged folks will be more likely to have a severe second-shot response than seniors.

“Generally speaking, the older you are, the tendency toward being so immunologically reactive goes down,” Poland said.

Covid Vaccine Effectiveness Against Virus Variants

Although more and more Americans are receiving vaccinations, COVID-19 still looms due to variants and mutations that have developed over the past several months.

The Delta variant, also known as B.1.617.2, is among the most notable mutations to make headlines, first in India and now in the U.S. In fact, the Delta variant accounts for one in five new COVID-19 cases, according to recent CDC data.

The good news is the Pfizer vaccine was recently found to be 88 percent effective against the Delta variant two weeks after receiving the second dose. The effectiveness plummeted to just 33 percent when receiving only one dose. This is just another reason why its so important to get your second dose.

Why Are Side Effects Worse After A Second Dose Of Covid

Why feeling bad after your second COVID-19 vaccine dose may be a good sign

When it comes to the one-two punch delivered by two-dose COVID-19 vaccines, its the second shot that really wallops.

Kristen Choi can attest to that. Choi, a nursing researcher at UCLA, ended up with a host of symptoms, including a fever that peaked at 104.9 degrees, after she got her second shot last year. But the effects soon passed and they were well worth the much-needed protection against the pandemic, she said.

Im very grateful to have gotten the vaccine and to be able to have that protection, and really want to see that opportunity be made available to everyone, Choi said.

As more Americans line up for the COVID-19 vaccine, some are anxious about the second-dose side effects, which tend to be stronger than the first. But experts say that the symptoms, which range from a sore arm to headaches and nausea, are a sign that the second dose is doing its job: turbo-charging the immune systems response to the initial dose, and thus providing more vigorous and long-lasting protection against the virus.

Two of the three vaccines that are authorized for use in the U.S. one made by Pfizer and BioNTech, the other by Moderna require two doses, spaced three and four weeks apart, respectively.

Theres no special secret sauce to that second dose: Both the first and second shots are exactly the same. The first simply primes the immune system so that its ready to launch a more robust response when its time to roll up a sleeve once again.
