How Long Does Side Effects From Covid Vaccine Last

When To Call The Doctor

How long do the side effects from the COVID-19 vaccine last?

In most cases, discomfort from pain or fever is a normal sign that your body is building protection. Contact your doctor or healthcare provider:

  • If the redness or tenderness where you got the shot gets worse after 24 hours
  • If your side effects are worrying you or do not seem to be going away after a few days

If you get a COVID-19 vaccine and you think you might be having a severe allergic reaction after leaving the vaccination site, seek immediate medical care by calling 911. Learn more about COVID-19 vaccines and rare severe allergic reactions.

How Long Do Side Effects Of Second Covid

The COVID-19 vaccination drive is being conducted at full throttle in Singapore and nearly 4.4 million people have been given the first dose so far. Meanwhile, 18.9 lakh people were fully vaccinated on the island by June 12, 2021. Thats about 33 per cent of the population.

But the Covid-19 vaccination does have its own side effects once you get the jab. While some may feel mild effects of it like fever, rashes, or body pain. Others may see more adverse effects of it that can be life threatening.

Thankfully, only 0.004 per cent of the vaccinated population in Singapore is suspected to suffer adverse effects of the Covid-19 vaccine doses, a recent report states. Thats about 157 people out of 3.7 million Pfizer-BioNTech and Moderna jabs that were administered till May 23, 2021. These people had reactions severe enough to be life risk and resulted in hospitalisation, among other serious conditions.

However, no deaths have been linked to the vaccine, the Health Sciences Authority announced on June 11. With well over half the population receiving their first dose and gearing up for the second jab, its important to know about the effects of the second Covid vaccine.

/7can You Continue Taking Your Medications After Getting The Vaccine

Since a lot of people who have battled COVID-19 may be following up with medications that support their health or taking other medications to manage the conditions, it could be concerning to think if they would need to stop or alter the use of some medications. While vaccines are safe to use with many pre-existing conditions, doctors attest that most routine medications are safe to be used before or after vaccination. As long as you aren’t taking specific immunity-suppressing medications, there may not be a real need to stop or pause using these medicines. If at all you have doubts, check in with your doctor before scheduling the vaccine shot.

Pfizer Vaccine Side Effects

People who get the Pfizer COVID-19 vaccine will likely experience soreness, redness and swelling at the injection site, and potentially chills and fatigue. The Food and Drug Administration lists a couple of additional side effects for the Pfizer-BioNTech vaccine specifically, including muscle pain, joint pain, nausea and swollen lymph nodes.;

The FDA notes that most people experienced these side effects after the second dose of the vaccine.;

Reactions to the Moderna vaccine are similar to those reported after the Pfizer vaccine, which is also an mRNA vaccine.

Recipients of both the Moderna and Pfizer mRNA vaccines commonly reported pain at the injection site and redness after the first dose, along with fatigue and joint pain after the second dose.

The reactions to the mRNA vaccines have not been terribly different, certainly not to a degree that an individual should choose one or the other on the basis of side effects, said Liu.

In clinical trials, the Johnson & Johnson shot was associated with milder side effects compared to the mRNA shots.

Since Moderna and Pfizer require two shots and most side effects were from the second shot, the J&J vaccine may have slightly fewer side effects, said Swaminathan.

Do You Feel Worse After Vaccination If Youve Already Had Covid

Our research shows that people who had previously experienced COVID-19 were more likely to experience the systemic effects after vaccination.

Around a third of people who had COVID-19 in the past reported at least one systemic effect within seven days of getting a Pfizer vaccine, compared with one in five people who hadnât already had the virus.

Around one in twenty people who had previously had COVID-19 experienced after-effects for more than three days during the first week, and around one in fifty were affected for six days or more.

Possible Side Effects After Getting A Covid

COVID-19 vaccination will help protect you from getting COVID-19. You may have some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. Some people have no side effects.

Serious side effects that could cause a long-term health problem are extremely unlikely following any vaccination, including COVID-19 vaccination. Vaccine monitoring has historically shown that side effects generally happen within six weeks of receiving a vaccine dose. For this reason, the FDA required each of the authorized COVID-19 vaccines to be studied for at least two months after the final dose.

Completing Your Vaccine Schedule

Provinces and territories are responsible for planning their immunization programs. They will decide how best to incorporate the National Advisory Committee on Immunization’s guidance into their plans to meet their unique population needs.

Most COVID-19 vaccines require 2 doses. A second dose is essential for longer-lasting and optimal protection, including against variants of concern. If you have already had COVID-19 you may also be offered 2 doses.

A different COVID-19 vaccine may be offered for a second dose. This is known as a mixed vaccine schedule.

NACI recommends that mRNA vaccines should be offered for both first and second doses. Your health care provider may offer you the AstraZeneca Vaxzevria vaccine depending on your unique health situation. For example, if you’re allergic to an mRNA vaccine.

Before you arrive at your vaccination appointment:

  • talk to your health care provider about any questions or concerns you may have about vaccination
  • plan which strategies you’ll use during vaccination to limit discomfort or pain
  • contact your;provincial or territorial health authority;if you have additional questions about how to prepare for your vaccination

Why Does The Covid Vaccine Have Side Effects

What Are the Long-term Side Effects of COVID-19 Vaccine?

âThe most common side effects to COVID vaccines include pain at the injection site, fevers, chills, nausea, headaches, tiredness, and painful or swollen lymph nodes in the arm where the vaccine was injected,â says Dr. Vivek Cherian, M.D., a Baltimore-based internal medicine physician.

In the case of the COVID vaccine, side effects can be interpreted as a good sign. “Side effects from the vaccine are due to your body mounting an immune response, and everyoneâs immune response is different based on their overall health,” says Dr. Michael Richardson, MD, a family medicine doctor with One Medical. “Younger people have been found to be more likely to develop side effects, possibly due to their more robust immune system.”

That doesn’t mean you’ve got a weaker immune system or that your body isn’t responding well to the vaccine if you don’t get side effects, Dr. Richardson explains. It just means that different people’s bodies can respond differently to the same stimuli.

Worried about potential side effects of the COVID-19 vaccine? Are you unsure what activities are safe following vaccination? Whether youre vaccinated or not, will be reaching out to public health experts to get your concerns addressed about the COVID-19 vaccine.

Just send an email to and well get an expert to directly answer your question.

Vaccinations to protect from COVID-19 have grown in importance with the rise of the delta variant and surging infection numbers and hospitalizations across Alabama. We are taking your questions about the vaccines and getting answers from healthcare experts.

To get some answers, we consulted Paul Goepfert, director of the Alabama Vaccine Research Clinic at UAB. It should be noted that specific questions about your own health should be addressed with your primary care provider.

Question: What are the long-term possible side effects of each vaccine? What studies have been done which show the impact on the person 2-years or 5-years after receiving the shot? How is it possible to declare the shot safe when these answers remain unknown?

Answer: Vaccine side effects should improve after two days. Symptoms persisting after a week would be highly unusual and may be due to something else, Goepfert said.

How Long Will Covid

Pfizer CEO Albert Bourla recently said that the data the notion that likely there will be a need for a booster somewhere between 8 and 12 months.

When Nelly Furtado sang All Good Things in 2006, she probably wasnt referring to the protection offered by the Covid-19 vaccines. Nevertheless, few believe that the immune response to the Covid-19 vaccines will last forever. Even if you are fully vaccinated now, you will likely have to get another booster shot sometime in the future. The question is when. And the answer is wait for it, wait for it.

Right now the guess is sometime between six months and two years after you were fully vaccinated the first time around. Pfizer CEO Albert Bourla did address this question during a recent Axios interview seen here:

As you can see, Bourla said that the data supports the notion that likely there will be a need for a booster somewhere between 8 and 12 months. So perhaps the Covid-19 vaccine will be a bit like the seasonal flu vaccine, a yearly thing. However, as Carlie Porterfield has reported for Forbes, not everyone agrees yet with this possibility.

How Are We Monitoring The Coronavirus Vaccines


Pfizer and Moderna continue to monitor immunity in people who were given their vaccines in the initial clinical trialsboth companies reported strong overall efficacy at the six-month mark. ;

One thing researchers are monitoring in vaccine recipients is levels of antibodies, which are proteins produced by the bodys immune system when it detects harmful substances, and that are easily measured from blood samples. Antibodies are a really good marker for protection against infection, so we will be monitoring those levels for as long as we can measure them, says Akiko Iwasaki, PhD, a professor of immunobiology at Yale School of Medicine.

I tell my family, ‘It’s great that youre vaccinated… But even the vaccines dont have 100% guarantees, so… you want to keep weighing the risks,'”;says Yale Medicine infectious diseases expert Jaimie;Meyer,;MD,;MS

A report in;The New England Journal of Medicine; in April showed that 33 participants who had received the Moderna vaccine during the Phase I trial had a gradual decline in antibody protectionand, based on the slope, Iwasaki says, that is hopeful news. If antibodies are going down very quickly, you would expect that to last for a short time. The slow decline raises hopes that the mRNA vaccines will be protective for at least a year, if not longer, she says. ;

This is a reason why the CDC recommends vaccinations for people who have had a COVID-19 infection as well as for those who have not.

Moderna Vaccine Side Effects

For the Moderna vaccine as well, common side effects remain typical: injection site pain and swelling, chills, fever, fatigue and headache . In a;company release;summing up the Phase 3 clinical trial analysis, Moderna reported that “no serious adverse events were noted in the trial.”;

In general, most people report worse side effects after the second dose of the Pfizer and Moderna vaccines, both of which are mRNA vaccinations.

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

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 to lower a fever, reduce chills, or relieve a headache or body aches. Its important that you do not take these drugs before getting your vaccine as there are theoretical 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.

Q: What Safety Data Did The Fda Evaluate To Authorize The Pfizer

A: The available safety data to support the EUA include 37,586 of the participants enrolled in an ongoing randomized, placebo-controlled international study, the majority of whom are U.S. participants. These participants, 18,801 of whom received the vaccine and 18,785 of whom received saline placebo, were followed for a median of 2 months after receiving the 2nd dose. This is consistent with the recommendations set forth in the FDAs October 2020 Guidance on Emergency Use Authorization for Vaccines to Prevent COVID-19.

The most commonly reported side effects were pain at the injection site, tiredness, headache, muscle pain, chills, joint pain, and fever. Side effects typically started within two days of vaccination and resolved 1-2 day later. Of note, more people experienced these side effects after the second dose than after the first dose, so it is important for vaccination providers and recipients to expect that that there may be some side effects after either dose, but even more so after the second dose.

The FDA also evaluated additional safety data from the larger database that included participants enrolled later during the study who had shorter follow-up . The FDA determined that the findings were similar to those in the population of participants with a median follow-up of 2 months after the 2nd dose.

More People Died In Alabama During 2020 Than Were Born As Covid

Mayo Clinic Insights: Why do the COVID-19 vaccines cause side effects

Alabama had more people die last year during the onset of the;Covid-19 pandemic;than births, a top health official said, as the US continues to grapple with rising coronavirus cases and deaths.

This past year, 2020, is going to be the first year that we know of in the history of our state where we actually had more deaths than births, Alabama Health Officer Dr. Scott Harris said Friday during a news briefing.

Our state literally shrunk, he said.

Preliminary data shows that 64,714 people died in Alabama in 2020 while there were 57,641 births, Harris said. In 2019, the state recorded 54,109 deaths and 58,615 births, according to the;health department.

According to;state data, 7,182 people in Alabama died due to Covid-19 in 2020 and total Covid-19 deaths reached 13,209 as of Saturday.

Even though more than half of the country is fully vaccinated, Covid-19 cases, deaths and hospitalizations have been rising over the past few months and its not impacting everywhere equally.

In Alabama, where 41% of people are fully vaccinated, according to;data;from the US Centers for Disease Control and Prevention , officials said more hospital beds have recently become available, though its not because people are recovering from the virus.

Is The Pfizer Vaccine Working

While the full course of the Pfizer vaccine is two shots up to 12 weeks apart, the good news is that it seems to provide some degree of protection after just the first dose.

Our data shows a 58% reduction in infection rates between 12 to 21 days after the first dose of the Pfizer vaccine, improving to a 69% reduction after 21 days.

You Should Wait To Get The Second Shot If You Catch Covid In

The CDC says you should not get the vaccine if you are currently infected with COVID. So if you do get the coronavirus in-between the first and second dose of Pfizer or Moderna, you should postpone your second shot. “Vaccination of people with known current SARS-CoV-2 infection should be deferred until the person has recovered from the acute illness and they have met criteria to discontinue isolation,” the CDC says.

If you do need to delay your second dose, the agency says it can still be administered up to six weeks after the first dose. However, if you are just experiencing side effects after the first shot and not the virus, you should still get your second shot on time “unless a vaccination provider or your doctor tells you not to get it,” the CDC says.
