When Do Side Effects From Vaccine Occur

Booster Vaccinations With Moderna And Biontech: This Is What Stiko Recommends

How to reduce potential vaccine side effects


Booster vaccinations with Moderna and Biontech: This is what Stiko recommends Created: 12/23/2021, 04:45 AM From: Bettina Menzel The standing vaccination commission Stiko recommends a booster vaccination after six months. But which side effects can occur? Munich – Almost 14 million people in Germany have received their booster vaccination . But there is still a lot to be do

How Long Protection Lasts

We do not yet know how long the protection from COVID-19 vaccines will last. Ongoing research around the world is evaluating:

  • how long protection lasts
  • whether you will need booster doses, such as an annual booster.

On 12 December 2021, ATAGI recommended the use of a single booster dose for those who have completed their primary COVID-19 vaccine course at least 5 months ago. Learn more about booster doses.

What Are The Known Side Effects Of The Vaccines

As with many vaccines, there are some side effects, says Dr. Scheraga, but those side effects are relatively mild. The side effects are mainly:

The data shows that side effects are more commonly felt after the second dose of Pfizer or Modernas vaccine rather than after the first dose. With Johnson & Johnsons vaccine, commonly reported side effects were arm soreness, headache, muscle aches and nausea. Most of the side effects occurred one or two days after vaccination.

What Tts Symptoms Should I Look Out For

It is important for people with symptoms of TTS to get medical attention early as this may help to prevent more serious complications. People should seek immediate medical attention if they develop any of the following symptoms after vaccination:

  • severe or persistent headache, blurred vision, confusion or seizures
  • shortness of breath, chest pain, leg swelling or persistent abdominal pain
  • unusual skin bruising and/or pinpoint round spots beyond the site of vaccination.

While TTS is very rare, some people may have concerns that they wish to discuss with their doctor. Weighing up the potential benefits against risk of harm from COVID-19 Vaccine AstraZeneca includes information to help people make informed decisions about vaccination.

Reporting Adverse Events To Vaers

Health Care Personnel Flu Vaccination, Internet Panel ...

The Vaccine Adverse Event Reporting System is the nations early warning system that monitors the safety of vaccines after they are authorized or licensed for use by the U.S. Food and Drug Administration . Reports to VAERS of adverse events are classified as non-serious or serious:

Can You Get The Flu Vaccine And Covid

You can get a COVID-19 vaccine and a flu vaccine during the same visit, according to the CDC and based on extensive research with vaccines, Dr. Carney says. This gives people the opportunity to get vaccinated for both flu and COVID-19 at the same time, increasing their protection against both of these infections.

While there isnt a ton of information or research available on getting the COVID-19 and flu vaccines at the same time, the CDC makes their recommendation based on research into how people react to other combinations of vaccines. Its not clear if getting both vaccines at the same time will increase your chances of having side effects. Early research done in the U.K. of 670 adults shows that people who received their second COVID-19 vaccine and a flu vaccine at the same time were more likely to have local reactions, which includes side effects like arm pain and swelling near the injection site, compared to people who only got the COVID-19 vaccine, according to the November 2021 paper published in The Lancet2.

How Long Do Vaccine Side Effects Last

Typically, vaccine side effects only last a couple of days.

Vaccine side effects typically don’t last longer than a couple of days, Mathew says. Some people may experience side effects for several days. Side effects that were related directly to the injection site, like bruising and redness, should subside relatively quickly, while whole-body side effects like fever and headache may last longer.

If you’re still having side effects a week or more after you get a vaccine — COVID-19 or otherwise — call your doctor or go to urgent care. If you feel the effects are life-threatening , seek emergency medical care right away.

When To Seek Medical Attention

New, unexpected or persistent symptoms

Speak with a health professional if you are worried about a potential vaccine side effect, have new or unexpected symptoms, or if you have an expected side effect that hasnt gone away after a few days.

The COVID-19 vaccine side effects symptom checker can help and you can contact the Adverse Medicine Events line for information about side effects and to forward reports to the TGA. The service is, however, unable to provide medical advice.

Symptoms more than 4 days after vaccination

A very rare condition called thrombosis with thrombocytopenia syndrome has been reported as confirmed or probable in 139 Australians who receive their first dose of the AstraZeneca COVID-19 vaccine .18 There have been over 13.2 million doses of the AstraZeneca vaccine given. Australian data show that the risk of this very rare side effect is lower in people that are older. It appears that the condition is also more severe in younger people.19 Current estimates of risk are summarised in the following table.

  • rash or bruising not at the injection site that cannot be explained.21


Myocarditis and pericarditis are rare side effects that typically occur within 10 days of vaccination with the Pfizer or Moderna mRNA vaccines. Cases are usually short lived and resolve following treatment and rest.

Seek medical attention if you experience any of these symptoms

How Did Pregnant Women Respond After Getting Vaccines Do We Know If Pregnant Women Have Different Side Effects If They Get The Covid

Does the COVID-19 Vaccine Cause Long-Term Effects?

Women who were known to be pregnant were not allowed to participate in the clinical trials for COVID-19 vaccines. But, some women who were already enrolled in the clinical trials ended up getting pregnant during the studies.

There were no adverse outcomes, Campbell said. And there was no evidence that vaccines affected fertility.

00187-3/fulltext” rel=”nofollow”> New research unrelated to the clinical trials now appears to show that vaccines may be safe for pregnant women and that the antibodies to COVID-19 may cross from the woman to her unborn baby. One mom in western Colorado had received the vaccine while she was pregnant. After her daughter was born, she tested positive for antibodies to COVID-19. Researchers are working to learn more about vaccines for pregnant women, infants and children as fast as they can. Right now, UCHealth medical experts do not recommend testing your baby for COVID-19 antibodies if you got the COVID-19 vaccine during your pregnancy.)

Can I Get Heart Inflammation From Taking The Vaccine

Yes, there is a very rare possibility.

When people are diagnosed with heart inflammation after taking an mRNA vaccine, they face a very rare chance of death or severity of illness.

Myocarditis, also known as heart inflammation, was found to be associated with the Pfizer and Moderna vaccine although extremely rare, and mostly mild. In a study on over one million Pfizer-vaccinated people in Israel, scientists found 2.7 excess cases of heart inflammation per 100,000 vaccinated individuals.

Heart inflammation was also mostly found in men aged between 20 and 34, when it was found at all. Essentially, there were just 11 excess cases of heart inflammation per 100,000 infected individuals.

There is no Moderna-specific study on a similar scale, but global medical authorities continue to keep their finger on the pulse of how a vaccine is working. If a potential risk ever becomes substantial, then vaccine guidelines will be updated.

Natural Immunity And Disease Prevention

Vaccines help your immune system get ready to protect against a disease without making you sick.

You may become naturally immune after being exposed to a disease. However, the risks of severe complications or even death are much greater than the risks of a severe reaction after getting a vaccine.

For example, if your child gets meningitis naturally, they have a 1 in 10 chance of dying. Those that survive have a 1 in 5 chance of:

  • deafness
  • loss of limbs
  • brain damage

An infected person can also spread the disease to others in the community before they show symptoms. Groups at risk include:

  • older adults
  • those with underlying health conditions

What Itp Symptoms Should I Look Out For

We encourage people to seek medical attention if they experience signs and symptoms that could suggest ITP, such as unusual skin bruising or clusters of small red or purple spots that do not lose their colour when pressed. Unusual bleeding is another sign, for example bleeding from the nose or mouth that is hard to stop, or blood in the urine or stools.

No You Cant Get Covid

Serious Measles Vaccine Side Effects Extremely Rare ...

The COVID-19 vaccines will not give you COVID-19. Youre just getting a sequence of the protein spike of the virus. Youre not getting either an active or inactive part of coronavirus.

Youre just getting what is needed from the virus so your immune cells can develop a memory of it. That way if you do contract COVID-19 after full vaccination, your immune system will be able to fight it off quickly so you dont get sick, says Dr. Scheraga.

Moderna And Biontech: Which Short

The side effects of the booster vaccination are comparable to those of the second vaccination.

The studies available so far have shown that the third vaccination does not lead to an increase in side effects.

They are in the same range as after the second vaccination, says expert Christian Bogdan.

The short-term side effects with Biontech / Pfizer and Moderna usually occur within two days of the vaccination and usually subside within a few days.

On average, the symptoms do not last longer than three days.

This is based on data reported to the Paul Ehrlich Institute.

Nine out of ten people did not notice any side effects after vaccination.

The following tables relate to the ten percent who had vaccine responses.

For example, 80 percent of those vaccinated with Biontech noticed pain at the injection site.

Very frequent vaccination reactions at Biontech

  • Pain at the injection site

  • Fatigue

  • Headache

  • Muscle pain and chills

  • Joint pain

  • Fever and swelling at the injection site

Very common vaccine reactions with Moderna

  • Pain at the injection site

  • Fatigue

  • Headache and muscle pain

  • Joint pain and chills

  • Nausea and vomiting

  • Swelling and tenderness of the lymph nodes in the armpit, fever, swelling and redness at the injection site

How Serious Is Myocarditis

Myocarditis is often mild, and cases usually resolve after a few days with treatment and rest. Some cases are more serious and need to be treated in hospital. Our analysis has found about 60% of the patients with likely myocarditis were admitted to hospital. Four people were treated in intensive care, representing about 1% of all cases classified as likely myocarditis. This number has decreased since last week because one case was reassessed as unlikely to be myocarditis after further expert review. Most patients admitted to hospital were discharged within 4 days.

Are The Common Symptoms Worse For The First Or Second Shot

For the AstraZeneca jab, it seems such side-effects are more common after the first shot. When compared with the first dose, adverse reactions reported after the second dose were milder and reported less frequently, the MHRA noted.

However, for the Pfizer jab the reverse appears to be true. Side-effects such as fever, chills, tiredness and headache throughout the body were more common after the second dose of the vaccine, the US Centers for Disease Control said.

Read said: We are a little baffled about this, but it may be due to the fact that the Oxford University/AstraZeneca vaccine has an adenovirus vector, which stimulates the immune system strongly in the first dose and less strongly in the second.

Is The Pfizer Booster The Same As The First Two Shots

Possible Side Effects Of Coronavirus Vaccine Described

Yes. According to Pfizer, its COVID-19 booster would be a third jab of the same vaccine you got with the first two doses.

Are The Vaccines Safe

Yes, all three COVID-19 vaccines are safe and effective.

Theres a lot of concern because of the speed of development and whether or not mRNA vaccines are a brand new platform, says Dr. Scheraga. But its not brand new technology. This platform has been under development for this kind of real-time distribution for a while and was worked on prior to the pandemic.

The vaccines are safe, effective and potentially life-changing.

Total Adverse Event Reports To 19 December 2021

Anyone can report a suspected side effect, either:

  • directly to the TGA

You can report anonymously.

Learn more about how to report a suspected side effect to a COVID-19 vaccine.

The most frequently reported side effects suspected to be associated with the vaccines include injection-site reactions, such as a sore arm, headache, muscle and joint pain, fever and chills.

The TGA is closely monitoring reports in people aged under 18 years. To 19 December 2021, we have received about 2,900 reports after vaccination with Comirnaty and Spikevax . The most commonly reported reactions in this age group are:

  • chest pain
  • fever.

Ausvaxsafety A National Survey On Covid

This ongoing survey actively collects responses from Australians about adverse events after they have received a COVID-19 vaccine. The survey tells us what proportion of people experience an adverse event and what the most common reactions are. It also measures the percent of people who went to the doctor or missed work or study because of an adverse event. Reassuringly, survey results largely reflect what was seen in the clinical trials, with injection-site reactions, fatigue, headache, and muscle and joint pain being the most common reactions.

Results are given for everyone who took the survey, which is about 5 million Australians so far. Data is presented for each vaccine and for the first, second and third or booster doses. Vaccine safety data is also given for subgroups of the population including:

What Is Vaccination

5 Things You Can Do to Minimize COVID

Vaccination is an important way to reduce the risk of developing a number of infectious diseases. The diseases vaccines prevent can be dangerous or even deadly. The benefits of having a vaccine greatly outweigh the risks of not having a vaccine and harmful effects from the disease. Read more about a range of vaccination topics.

How Common Is Itp

It is very rare after COVID-19 vaccination. In Australia, ITP has been reported in less than one in every 100,000 people following the Vaxzevria vaccine.

To 19 December 2021, the TGA has received 84 reports of suspected ITP following vaccination with Vaxzevria . This number has decreased since last week following a review which identified some duplicate reports and reassessed some cases with new information. These patients had an extremely low platelet count, and signs of thrombocytopenia which may include unusual bruising, a nosebleed and/or blood blisters in the mouth. Their symptoms occurred in a timeframe that suggested they could be linked to vaccination and no other obvious cause was identified based on the information provided to the TGA.

Reports Of Very Rare Blood Clots

The Medicines and Healthcare products Regulatory Agency is carrying out a detailed review of reports of a very rare blood clotting problem affecting a small number of people who have had the Oxford/AstraZeneca vaccine.

The problem can also happen in people who have not been vaccinated and it’s not yet clear why it affects some people.

The current reported rate of this condition in the UK is around 15 cases per million first doses given.

The coronavirus vaccine can help stop you from getting seriously ill or dying from coronavirus. For people aged 40 or over and those with underlying health conditions, the benefits of being vaccinated outweigh any risk of clotting problems.

For people under 40, it’s currently advised that it’s preferable to have either the Pfizer/BioNTech or Moderna coronavirus vaccine.

If you have already had a first dose of the Oxford/AstraZeneca vaccine without suffering any serious side effects you should complete the course .

This includes people aged 18 to 39 years who are health and social care workers, unpaid carers and those who live with someone with a severely weakened immune system.

Who Is At Risk Of These Heart Problems

Myocarditis is more commonly reported in young men and teenage boys after the second dose . However, even in this population it remains rare.

A European review of myocarditis and pericarditis data in teenage boys and young men found for Comirnaty, there were 26 extra cases of myocarditis per 100,000 vaccinated individuals compared to unvaccinated individuals. For Spikevax, there were 1319 extra cases of myocarditis per 100,000 vaccinated individuals compared to unvaccinated individuals.*

*Correction: in the last 2 TGA vaccine safety reports, we incorrectly quoted the number of extra cases of myocarditis per 100,000 vaccinated individuals as less than 1 extra case for Comirnaty and 12 extra cases for Spikevax. This has now been corrected . We apologise for this error.
