Why do I catch a cold after getting a viral vaccine?

Vaccines are only effective against one or more viruses that have caused epidemics, and are not effective against new viruses or the common cold caused by colds.

It takes half a month after vaccination, the human body can produce antibodies, in layman's terms, it is to produce resistance, during this period people with low immunity may still suffer from influenza, and the validity period of the flu vaccine is only one year, and it needs to be re-vaccinated after one year, and the recommended vaccination time in China is from September to November every year.

Studies have proved that even if you are infected with influenza again, as long as you have been vaccinated, the symptoms will be milder than those of people who have not been vaccinated, and the course of the disease will be shorter, especially the probability of serious complications caused by influenza will be much reduced, so it cannot be considered that the flu vaccine is ineffective, and you can gain immunity to the same type of virus after being infected with the influenza virus, but there is no cross-immunity between the individual type and the subtype, and you can reverse the disease, so you can not benefit for life after getting the flu, and you still need to strengthen exercise and pay attention to the prevention of influenza.

Go to consult. Disease analysis: the vaccine is a kind of live attenuated vaccine developed by the predecessors of medical workers through unremitting efforts, the vaccine is an allogeneic for the human body, after being injected into the human body, the baby with low immune function will have some low-grade fever reactions, most of the body temperature fluctuates above the degree, below 38 degrees, don't worry, this fever does not belong to the cold, it is a normal reaction to the vaccine, no special treatment is required, observation for 3 days is basically fine, individual body temperature is more than 38 degrees, can be physically cooled, If fever persists, ibuprofen suspension can be taken by mouth.

Everyone's reaction to the vaccine is different, most of them are not reacting, some people will have headaches or lack of energy, colds, this is a normal reaction, it will be fine in two days, my family of three has already been vaccinated, nothing happened.

After the flu vaccine, the body may become weak, at this time, if you have a cold or have symptoms of runny nose, you need to drink more water, do not need to do other **, if you have a fever or cough, then take other relevant ** measures, in short, in the case of the condition is not serious, you can do some physical **, and to prevent the symptoms of wound infection.

Vaccinations are not recommended when you have a cold for the following reasons:

1. Because when we have a cold, our immunity is relatively low, and the vaccine is generally a live attenuated vaccine, which weakens the toxicity, but there is still some toxicity, so that when you have a cold, it will make the cold worse, and even when you are about to recover, after injecting the vaccine, it will lead to fever again, and the cold will not heal. Clause.

Second, the purpose of vaccination is to make the immunity respond and produce antibodies, but because the immunity is relatively low during the cold, it is not easy to produce antibodies, and the probability of successful vaccination is relatively low. Clause.

3. When vaccination, because it is a live attenuated vaccine, there are generally mild cold symptoms, which are easy to overlap with the symptoms during the cold, and it is not possible to judge the current symptoms caused by their own infection or caused by the injection of vaccines.

Vaccination is the injection of vaccines and other biological products into the human body, so that the body can produce a beneficial immune response against infection to achieve the purpose of preventing corresponding diseases. Generally, after vaccination, some people will have fever, local injection of redness, swelling, pain and other inflammatory reactions, which is normal, but if you have a cold at this time, the body's resistance is reduced, and vaccination is likely to aggravate the symptoms of the cold, and at the same time affect the effect of vaccination, so it is still recommended to vaccinate after the cold has healed.

It is not possible to take a vaccination during the cold period, because after the vaccination, some people will have a vaccine reaction that causes fever, headache, rash, diarrhea and other symptoms, which will aggravate the cold, which is not conducive to the recovery of the cold condition, and may also affect the efficacy of the vaccine. It is recommended to wait five to seven days after the cold before getting vaccinated.

Most colds are caused by viruses, which can be carried out by oral antiviral oral liquid, paediatric aminophen xanthamine granules and other drugs**.

If it is accompanied by a cough, cough syrup can be taken**. After vaccination, you will be observed in the hospital for half an hour before you can leave the hospital.

If there are no adverse reactions, you can leave. If there is an adverse reaction, it is necessary to inform the doctor in time and carry out relevant treatment to avoid adverse effects on health.

Generally speaking, it is best not to vaccinate during the cold, especially in the case of fever caused by a cold, it is strictly forbidden to vaccinate, of course, if there is an emergency that must be vaccinated, then the case of a cold without a fever can also be considered, and there are professionals at the vaccination site, you can consult further.

If you have a cold, you can't get vaccinated, no matter what vaccine you get, as long as you have a cold, you can't get vaccinated, and you can only get vaccinated a week after you get better.

It is not recommended to get vaccinated during the cold period to avoid affecting the recovery of the condition.

When the patient has a cold, the immunity is low and it is easy to cause viral and bacterial infections, and the main component of the vaccine is to inactivate viruses or bacteria, which are foreign substances in the body and may contain some toxins or viruses. Vaccinations given in the event of a cold can cause viral or bacterial infections with the vaccine, which can cause fever and other complications. Therefore, it is not recommended to get vaccinated during a cold, and it is generally possible to get vaccinated about a week after the cold symptoms have resolved.

Try to get vaccinated when you have a cold or when you have various diseases, people with high blood pressure, try not to get vaccinated to prevent ***, and when your cold symptoms disappear, then go to the vaccine, which is good for your body

It is not recommended to take the vaccine when you have a cold, because the body's immunity is relatively low when you have a cold, which is easy to cause infection of viruses and bacteria, and the main component of the vaccine is inactivated viruses or bacteria, which are foreign substances in the body and may contain some toxins or viruses.

Vaccines should not be given for colds, because all vaccinations cannot be given during an acute infection in the body. A cold is a viral infection of the respiratory tract, and it is an acute respiratory infection, so you should not be vaccinated during the onset of the disease.

Disease analysis: can you take a look at what kind of cold advice and suggestions: what we call vaccination is to inoculate vaccines and other biological products into the human body, so that the body can produce a beneficial immune response against infection, so as to achieve the purpose of preventing corresponding diseases.

Colds are inflammation of the upper respiratory tract caused by viral or bacterial infections, so try not to get vaccinated when you have a cold. People with colds often experience symptoms such as cough, phlegm, chills, and fever, and they feel very unwell.

If you have a cold, don't get vaccinated first, and get vaccinated after the cold is cured, which is safer.

No. Even if you get a flu shot, you can get the flu. The reason for this is that the flu vaccine can prevent a limited number of types of influenza, and new types of influenza emerge every year.

No, the flu vaccine only prevents some types of influenza, not all influenzas, and it only plays a certain protective role, and it cannot be said that the flu is completely influenza.

You can also get the flu, the flu virus is easy to mutate, even if you have been vaccinated against the flu, there is still a risk of the flu, it can only be said that the risk of the flu is reduced, and it will not disappear completely.

Analysis: Why do I still catch a cold after getting the flu vaccine?

Home 》Disease Control Information》Why do I still catch a cold after getting the flu vaccine? Close the window.

Epidemic ** flu (referred to as "influenza") is an acute respiratory infectious disease caused by influenza virus, which is harmful because of its rapid epidemic and the various serious complications it causes. During the flu season, people tend to take various precautions such as smoking vinegar, opening windows, drinking antiviral powders, and getting vaccinated against influenza, which is currently the most effective way to prevent influenza.

However, I have also met some people who are unimpressed with the flu vaccine: "I got the flu vaccine last year, but I still don't catch a cold?" "I've had a flu shot and I still get the flu, is it still useful?" "Actually, these people still don't know much about the flu vaccine.

First of all, the pathogens that cause influenza and the common cold are different, the former is influenza virus, while the latter has more than 200 pathogenic microorganisms, mainly rhinovirus and mycoplasma. Influenza vaccine is only against influenza viruses, especially influenza A1, A3 and B, which are highly susceptible to influenza epidemics. Therefore, the flu vaccine will only produce antibodies to the corresponding influenza virus strains, and has no effect on the pathogenic microorganisms that cause colds.

Knowing this, you can understand why the flu vaccine does not protect against the common cold.

Secondly, it takes 1 to 2 weeks after the flu vaccine to reach the peak of antibodies in the body. Therefore, to get the flu vaccine, you must rush half a month before the arrival of the flu epidemic season. If you are infected with the influenza virus just after vaccination, the antibodies in the body are not enough to fight the influenza virus, and you may still get the flu.

Generally speaking, the elderly and the frail are often more likely to get the flu due to their lower immunity. Therefore, flu vaccination should be prioritized for this group of people. However, for healthy people and young adults, there is also a risk of influenza virus infection, so they should also be vaccinated against influenza at the right time and should not be careless.

Since the influenza vaccine is prepared from chicken embryos, people who are allergic to eggs should not be vaccinated. In addition, those who have acute infection, fever, advanced cancer, cardiopulmonary failure and severe allergies should not be vaccinated against influenza.
