You experience no pain no fever after vaccination? Learn more about the causes of vaccine-induced fevers and how to prevent them from happening again.

The unusual side effects of the coronavirus vaccine have been the hottest topic ever since the beginning of the vaccination drive. Fever, sore arms, headache and muscle pain are some symptoms that show that the shot is doing its job of producing antibodies against the virus. But not everyone witnesses these reactions after getting the jab, which has made people wonder if it meant their vaccine dose didn’t work. While most people experience side effects after getting the vaccine, it is not mandatory in every case. The intensity of the side effects depends on several factors, including your age, the type of the vaccine, whether you have had COVID, and others.

No Pain No Fever After Vaccination

Coronavirus vaccines have been proven to be well-effective against coronavirus and can even potentially curb severity rates. Of course, side-effects are something that accompanies vaccines, some usual, other unusual and some downright severe enough to prompt action. However, with more and more people getting vaccinated, it has become clear that the side effects aren’t uniform for everyone. Some get the typical ones, some suffer from the greater intensity of it, while some escape unscathed and have no side effects. But why does this disparity happen? 

Why do some people get side effects after coronavirus vaccination and some don’t?

Side effects refer to the reactions that take place when the body is exposed to an external antigen. The way our system reacts to the same shows up as vaccine side effects.

What do vaccine side effects mean?

Upon exposure, our immune system kicks into action. While the first part sends white blood cells and defensive antibodies to fight the pathogen, it also prompts inflammatory responses against the infection, making a person experience symptoms like fever, fatigue, muscle soreness, pain, chills, etc.

These are also what many refer to as the common side effects and reactions expected with vaccines.

Some unusual side effects or inflammatory reactions may also occur, depending on how a person reacts to the vaccine.

Side effects depend on how your body reacts to the vaccine

While side effects can be experienced, it is common knowledge that no two bodies react the same way to the same vaccine. It can also happen that different vaccines showcase different responses. For example, it has now been shown that the ‘A’ vaccine doles out ‘fewer’ inflammatory reactions compared to the ‘B’ vaccine.

Therefore, whether a person reacts to a vaccine, or has the same reactions as someone else, depends on the way the individual system reacts to the antigen in the vaccine. Clinical trials from Pfizer’s mRNA vaccine study also observed that over 50% of people reported suffering from no side effects after getting the jab, and were still protected.

Apart from this, factors like age, gender, pre-existing immunity, health conditions, use of anti-inflammatory medicines may also affect the side effects you get. This is one reason younger people report more side effects than older people do. Newer research also shows that the time of the day a person gets jabbed may also affect inflammatory reactions.

Women get more vaccine side effects than men

Increasing data has shown that the side effects and vaccines work differently across genders. Women, more than men, experience harsher and more intense side-effects from the vaccine doses, compared to their counterparts. This could also lead to a difference in reporting of symptoms between men and women.

One reason women experience more side effects could be because of the way hormones interact with the immune system make-up. Heightened estrogen levels may lead to more inflammatory reactions and increase the duration of the side effects as well. Hormonal interference may also make women experience some different side effects, such as swollen lymph nodes under the arms as well. Compared to this, men have not been shown to report any distinct side effects with vaccines.

No side effects from covid vaccine mean weak immune system?

Whether you develop any side effects after getting the shot or not, this factor does not determine the effectiveness of the vaccine. People respond differently to vaccines and it is completely normal even if you stay active and feel better after getting the shot. There are no reasons to believe that the vaccine is less effective.

No side effects after the covid vaccine mean the vaccine is not working?

There looms a question, what happens if you don’t get any side effects? Does it mean that your vaccine is still working? The answer, according to many experts, is that no show side-effects shouldn’t be a reason right now to get concerned. Every vaccine works in the same way and not getting any side effects, or the ones which may be barely noticeable, may only mean that your body is reacting to it differently. In no way does it imply that the immune system has not accepted the vaccine, or the vaccine may not be working. It can also happen that a person who doesn’t develop side effects after the first shot gets side effects with the second dose. Or, it can happen that reactions do not show up altogether. As long as sufficient antibodies are produced, and you follow utmost COVID appropriate behaviour, there’s nothing to be worried about.

What happens if you get sick after being fully vaccinated? Should you get tested?

Remember vaccines do not prevent COVID-19 completely. As helpful as COVID vaccines currently are, they do not work as anti-COVID drugs, and the newer variants of concerns that spread may also lower the efficacy rates of the vaccines. So, there is very much a possibility that you can catch coronavirus, after being vaccinated, and hence, no complacencies should be entertained. However, remember that these infections, or breakthrough cases, as they are called, are still rarer in numbers? So, even if there is a real risk of the virus causing infections, the risk is on the lower side. As data has suggested, different vaccines carry a distinct risk of breakthrough infections and symptomatic risks.

Does age and sex matter for covid vaccine side effects?

Your age matters for the side effects of the vaccination. Studies suggest people aged 30 to 44 are most likely to report side effects. Adults, older than 65 years, experience fewer side effects overall. This does not mean that vaccines won’t work well in older adults. The potential reason younger people develop severe symptoms could be a stronger immune system. The COVID shot triggers an immune response, which can lead to side effects. Data also suggests that vaccines work differently across genders. Women experience more intense side-effects as compared to men. The major reason behind this could be different hormones in the body.

No side effects after vaccination conclusion

After taking the vaccine against COVID-19, many people experienced side effects including sore arm, tiredness, headache, fever, or nausea, which is a sign that the immune system is responding well to the vaccine. But they are many people who have experienced no side effects at all, this does not mean the vaccine is not working properly. If you don’t feel crummy after getting jabbed, chances are that your body still had a good protective immune response.

In various vaccine clinical trials, it showed that 50% of participants experienced no side effects during the trial, and 90% of them developed immunity against the virus.
