How Long Do Side Effects Of First Covid Vaccine Last

What Do We Know About Long

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

Since December, more than 200 million people have received at least one dose of a COVID-19 vaccine worldwide more than the total number of people who have been infected with the virus .

Given the sheer number of vaccines administered to date, common, uncommon and rare side-effects would have been detected by now. Whats more, weve been testing these vaccines in clinical trials since mid-2020, and both the Pfizer and AstraZeneca vaccines have shown excellent safety results.

This gives us confidence the vaccines thatll be used around Australia are safe.

Weve also seen some people raise concerns online about mRNA vaccines, such as the Pfizer-BioNTech vaccine, being a new technology. mRNA is found in all living cells. mRNA is a message that tells cells how to make proteins that trigger the immune response inside the body. That immune response is what protects against infection if an individual is exposed to the virus. mRNA is not the same as DNA , and it cannot combine with our DNA to change our genetic code. mRNA vaccines do not affect or interact with DNA in any way. So we can be assured therell be no long-term DNA-altering effects from these vaccines.

Whats more, checking the safety of the vaccines doesnt just stop after theyve been registered for use. Once a vaccine has been introduced, ongoing monitoring of its safety is a crucial part of the vaccine development process.

Both of these side-effects were observed within weeks of vaccination.

Blood Products Human Immunoglobulin And Timing Of Immunization

NACI recommends that COVID-19 vaccines should not be given simultaneously with monoclonal antibodies or convalescent plasma.

To date, there is insufficient evidence on the receipt of both a COVID-19 vaccine and anti-SARS-CoV-2 monoclonal antibodies or convalescent plasma for treatment or prevention. Therefore, timing of administration and potential interference between these two products are currently unknown. Administration of these products close together may result in decreased effectiveness of a COVID-19 vaccine and/or anti-SARS-CoV-2 monoclonal antibodies because the monoclonal antibodies have high affinity for the spike protein expressed by the vaccines, which could prevent the production of antibodies stimulated by the vaccine.

In the post-exposure setting, expert clinical opinion should be sought on a case-by-case basis when deciding whether anti-SARS-CoV-2 monoclonal antibodies would be appropriate to administer after receipt of COVID-19 vaccine, taking into consideration the risk of exposure and the risk of severe COVID-19 disease in the individual.

To date, there is also insufficient evidence on the receipt of both a COVID-19 vaccine and any monoclonal antibodies or convalescent plasma for treatment or prevention of non-COVID-19 disease. Therefore, timing of administration and potential interference between these two products are currently unknown and expert clinical opinion should be sought on a case-by-case basis.

/7how Many Doses Would They Require

Severe side-effects can kick in with any scheduled dose of the vaccine- be it first or second. While it may happen that the severity of the side-effects subsides if one suffers from intense side-effects with the first dose, multiple studies have found that for recovered patients, even a single dose may be able to elicit the requisite robust immune response two doses would guarantee. This is because the immune system recognizes the pathogen’s spike protein from before, and rushes to mount a good response.

Another recent study also found that recovered COVID-19 patients, of all sections and prioritized groups, have the highest levels of protection from specific vaccines.

What Can I Do To Relieve The Discomfort Of Covid

What to expect after a COVID

Depending on your symptoms, you may try:

  • putting a cold compress on the injection site
  • using your arm, rather than keeping it inactive, to reduce injection site discomfort
  • checking with your doctor to see if you can take over-the-counter painkillers
  • drinking lots of fluids
  • wearing lighter clothing, if youre feeling feverish

The More Common Less Worrisome Issue: Feeling Sick After A Shot

With the two-dose mRNA vaccines from Pfizer and Moderna, the second shot proved to be a real doozy for some who rolled up their sleeves. It wasnt universal, but lots of people felt fluish, feverish, and achy for a day or two, typically after their second shot.

The culprit was the immune system really ramping up. If the first shot provided the bodys defenses with the scent of a key protein from the SARS-CoV-2 virus, then the immune system was ready to pounce when it saw that spike protein again with shot #2. It was all in the name of building up a lasting and robust blockade in the body, but it did mean some people had quite a hangover after the second dose.

The immune system goes, I know what this is, and attacks it more vigorously, said Kawsar Talaat, a Johns Hopkins infectious disease physician and vaccine researcher.

Talaat said that its possible that, because the immune system is already primed to recognize and target the spike protein, some people could experience something similar after a third dose.

Potential Side Effects After Taking Covid

Some of the more common side effects of the Covid-19 vaccine include the following:

  • Pain

  • Fever

  • Nausea

The HSA says that the reactions can possibly be associated with the vaccination but may not have been caused by it. Healthcare providers reported to the HSA saying that any undesirable medical condition which occurs after taking the vaccine does not necessarily have a direct link to the treatment.

It may be coincidental or related to undiagnosed disease.

Why Do I Feel Tired After Getting The Covid Vaccine

It might feel crappy to crash out hard after getting your COVID vaccine, but it’s not actually a bad thing in terms of what’s happening in your body. “When people experience fatigue after a COVID vaccine, itâs usually an indication that our immune system is working,” says Dr. Natasha Bhuyan, M.D., the regional medical director of One Medical. “As our immune system mobilizes cells to fight off the virus in the future, itâs normal for us to feel a sensation of fatigue.”

You may also feel more wiped out after the second shot than you did after the first, and thatâs normal, too. âBecause the body has already started to develop antibodies after your first dose, your body responds more robustly after your second dose and you are more likely to be fatigued or have more pronounced side effects in general,â says Dr. Vivek Cherian, M.D., a Baltimore-based internal medicine physician. So even if the first shotdidnât knock you out, itâs not uncommon for the second to hit you like a truck.

Can I Treat The Side Effects

Many report side effects after second COVID-19 vaccine dose

If you have pain or discomfort after receiving your vaccination, talk to your doctor about taking an over-the-counter medicine, such as ibuprofen or acetaminophen .

To reduce pain and discomfort on your arm:

  • Apply a clean, cool, wet washcloth over the area.
  • Use or exercise your arm.

In most cases, discomfort from fever or pain is normal. Contact your doctor or healthcare provider:

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

General Vaccine Side Effects

All vaccines have possible side effects with mild to moderate severity. Typical vaccine side effects include local pain, swelling, redness and sometimes bruising at the injection site, as well as fever and tiredness, says Dr. Roshni Mathew, pediatric infectious diseases physician at Stanford Children’s Health.;

With any vaccination, you can expect a bit of pain during and after the injection, says Dr. Thomas Duszynski, director of epidemiology education at Indiana University. He adds that some people may experience chills, fatigue or minor headaches after vaccines.;

Sandra Lindsay, a nurse at Long Island Jewish Medical Center, is inoculated with the COVID-19 vaccine.

According to the Centers for Disease Control and Prevention, common COVID-19 vaccine side effects include:;

  • Injection site pain
  • Tiredness

Want To Be Part Of The Largest Independent Community

We need to gather as much data as we can about the impact and any after-effects of COVID-19 vaccines to support the rollout and help end the pandemic.

If youâre not already using it, and use it to record your COVID-19 vaccine, followed by daily health reports to help us monitor the after-effects and impact of vaccination.

You can also register a profile and log reports on behalf of relatives or people you are caring for who may not be able to use the app themselves.

Together weâll get through this. Stay safe and keep logging.

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.

Will I Be Compensated If I Have An Adverse Reaction To The Vaccine

Winners and Losers in the Wake of Positive COVID 19 ...

While the Australian Government strongly supports immunisation, it is not compulsory. People, parents and carers maintain the right to choose whether to receive a vaccination.

The Government is not currently pursuing a no-fault COVID-19 vaccine injury compensation scheme. Serious side effects are extremely rare. If you think you may be having an adverse reaction, you should seek immediate medical care.

How To Report Covid

The CDC launched a tool that allows people who have received one or two doses of any COVID-19 vaccine to track and report side effects. The tool, called V-Safe After Vaccination Health Checker, uses messaging and survey functions to automatically check in on people after they get vaccinated. You can on your smartphone after getting the vaccine. You’ll need your vaccine info handy, including which type of vaccine you received and the date and time you received it. Using the chat function, you can tell the tool your side effects. Someone from the CDC may call you and ask for more information if you report severe or unusual side effects.

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.

Why The First Dose Is Effective

This also adds to the body of evidence that one dose might be enough for those who had COVID-19, at least in the beginning. As I wrote for the Deseret News, theres research out that says the first dose of the Pfizer COVID-19 vaccine which has two shots can create high efficacy in fighting the novel coronavirus. In fact, the first dose of the Pfizer COVID-19 vaccine has been found to be 85% effective against COVID-19 symptoms after 15 to 28 days, The Wall Street Journal reports.

That same study found it has 75% efficacy against stopping asymptomatic cases of COVID-19, too, per The Hill.

That said, experts still recommend people get both doses of the COVID-19 vaccine for full protection against the coronavirus.

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 Common Were Side Effects

In total, 954 healthcare workers at Johns Hopkins Medical took part in the research. All of them had received either the Pfizer or Moderna vaccine, and some had previously had a SARS-CoV-2 infection.

What indicated an infection was either having a positive SARS-CoV-2 PCR test within 14 days of the second vaccine dose or having an elevated IgG antibody count before receiving the vaccine.

The researchers asked the participants to report their reactions to their first and second inoculations. They could report none, mild including injection site pain, headache, and mild fatigue or clinically significant symptoms, such as fever, chills, and fatigue.

Just 5% of the participants reported side effects after their first inoculation, although 43% said that they experienced side effects after the second one.

People who took the Moderna vaccine were more likely to have clinically significant symptoms after either dose, and those who had previous SARS-CoV-2 infection were more likely to experience them after the first shot but not the second.

Whether individuals experienced side effects or not, almost all 953 out of 954 developed IgG antibodies 14 days after their last vaccine dose.

The lone exception was an individual taking immunosuppressant medication.

Lead author Dr. Amanda Debes, of the Johns Hopkins Bloomberg School of Public Health in Baltimore, tells HUB, the news center for Johns Hopkins:

If You Do Have Covid It’s Not From The Vaccine However

If you do find out you have COVID after getting the vaccine, it’s not because the vaccine gave you COVID, however. As the CDC explains, none of the three COVID vaccines available in the U.S.Moderna, Pfizer, and Johnson&Johnsonare live vaccines, which means they cannot give you the virus they are protecting against. However, it takes a few weeks after vaccination to build immunity, which means “it is possible that a person could be infected with the virus that causes COVID-19 just before or just after vaccination and then get sick because the vaccine did not have enough time to provide protection,” the CDC says. And for more guidance from the CDC, The CDC Says Don’t Do This Within 2 Weeks of Your COVID Vaccine.
