Recently, residents in various places have been vaccinated against the new coronavirus in batches, which is a great thing
.
Once the immune barrier is formed, normal life and contacts with different places can be restored.
Everyone is looking forward to this day
.
However, many people say that vaccination will bring all kinds of discomfort, worry and fear
.

I myself received the first shot of the new coronavirus vaccine on February 21st
.
It was injected at 11:30 noon, and it didn't hurt at all
.
It has been 3 days since the article was published, and there is no abnormal physical sensation
.
Let me briefly explain a few questions about vaccine reactions
.
Friends who already know about these issues can pull to the second half of the article to see the measures
.

1.
Why do I feel tired easily after the vaccine, and I really want to sleep?

Many people have discovered that they feel fatigued after the vaccination.
People are more sleepy than before.
They get sleepy earlier, can't stay up at night, and sleep for a long time at night
.
This is a normal reaction
.

This is like conducting a military exercise, using imaginary enemies to mobilize the army
.
For countries with sufficient materials, sufficient funds, and strong military capabilities, conducting an exercise is not considered a major event, but because many departments have to serve the exercise, other activities that are not related to the exercise may be temporarily suspended in order to save manpower and material resources.
Focus on the central task
.

The body is the same
.
Because the immune system has discovered the inactivated virus from the vaccine, it needs to concentrate on dealing with the invading enemy, and other things must make way
.
The human body sends out a sleepy signal to urge you to lie down and sleep quickly, temporarily saving resources consumed by work, study, and exercise to the immune system, allowing the body to concentrate on fighting the "virus" during sleep
.

2.
Why do I have a great appetite after the vaccination, so I am especially hungry?

As mentioned earlier, the purpose of vaccinations is to use inactivated viruses to stimulate an immune response, but the body also needs to pay for this, consuming energy and nutrition
.
Everyone must have heard something like this: The army has not moved, the food and grass go first
.
To fight a big battle, the resources consumed are indispensable
.
Where does this energy and nutrition come from? Naturally it comes from three meals! Dr.
Zhang Wenhong repeatedly said that we must eat enough nutrients so that the immune system can fight the virus
.

Therefore, after the vaccination, many people feel that their appetite has increased
.
Especially for those who have low daily food intake, insufficient nutrition, and frequent diets to lose weight, when their body finds that their nutritional reserves are insufficient, they want to urge you to eat more
.
Why does Dr.
Zhang Wenhong repeatedly say that he must eat enough protein? Only in this way can the immune system be able to fight the virus
.

Perhaps many friends who have donated blood have this kind of memory: after donating blood, their appetite improves, eating is delicious, and appetite increases
.
This is because the body feels blood loss and determines that you are injured, urging you to increase your nutritional supply and repair the damage as soon as possible
.
Many girls have a similar appetite before their aunt's blood loss
.
It is very important to strengthen nutritional protection during disease recovery and postoperative recovery.
Appetite, nutritional quality, and digestion and absorption capacity determine the speed of recovery to a large extent
.

3.
Why do the first needle feel good, but many people feel uncomfortable with the second needle?

When the first injection is given, it is the first immune response
.
In other words, the human body may be the first to see what the new coronavirus (which has been inactivated and cannot harm the human body, but the appearance is still there)
.
When the human body first comes into contact with an antigen, it is not yet familiar with it.
The rate of antibody production is relatively slow, the amount of antibody produced is relatively small, with IgM being more, the maintenance time is relatively short, and the specificity of the antibody is relatively low
.
To put it in plain language, the body is not yet familiar with how to deal with this virus, the overall mobilization is not so in place, and the energy and nutrition consumed may be relatively small
.

When the second injection is given, there is another immune response
.
Because I have learned about this "enemy" before, and have a plan for it, the immune system responds faster and produces more antibodies, mainly IgG, and the specificity of antibodies is high, and the time to maintain antibody levels is longer
.
Naturally, there is a greater chance of temporary discomfort after vaccination
.

After two exercises, the body has firmly remembered the appearance of this virus, has vigilance and knows how to deal with it
.
This is why vaccinations can protect the human body
.
Therefore, don't give up the second vaccination because you are afraid that you will feel a little uncomfortable after the vaccination, otherwise your previous efforts will be lost
.

However, there is also the reverse situation
.
For example, when the first shot was overworked, I was overworked and fatigued, and the reaction was relatively large.
When I took the second shot, it was during the Spring Festival.
I had enough rest at home and plenty of food every day, so I felt better with the second shot
.

4.
Why is it obvious to me that others have no bad feelings?

As mentioned earlier, a major exercise of the immune system requires nutrition and energy
.
The body may experience a temporary increase in the level of inflammation, because inflammation is a physiological response necessary to eliminate pathogens
.
For people with poor overall physical capabilities, or for people who are temporarily in poor physical condition, an immune exercise may make the body noticeably tired and even temporary inflammation
.
For example, cough, fever, sore throat, diarrhea, rhinitis worsened, and so on
.

Some people with allergic diseases may also find that asthma attacks, hives, food allergies, and so on
.
Before getting the vaccine, a doctor will ask about the relevant health conditions in detail to help you confirm whether you can get the vaccine, and you must sign an informed consent form
.
If you have various diseases and do not report them, you are responsible
.

5.
When vaccinated, I was told to avoid seafood, fresh beef, beef and mutton and spicy food within a week.
Why?

The advice of doctors and nurses is to prevent a few people from having adverse reactions after eating these foods
.
On the one hand, it is to prevent excessive inflammation
.
On the other hand, I am worried that the state of the immune system will temporarily change, and allergies may occur to foods that did not respond
.
For example, some people can eat seafood on a daily basis, but they will have adverse reactions when they are over-fatred or unwell
.
There is also this risk after vaccination
.

Although only a small number of people have had adverse reactions after eating these foods, it is impossible to identify them one by one.
For the sake of insurance, we advise that these diets are beneficial and harmless
.
Finally, I would like to summarize some precautions in diet before and after vaccination, which may help you reduce discomfort and strive for the best immune effect
.

1.
Get enough sleep and avoid staying up late

The importance of adequate sleep for immune function has been confirmed by countless studies, and it is also crucial for the long-term immune memory generated by the vaccine
.
A review article published in the journal Sleep Breath by researchers from West China Hospital showed that lack of sleep after vaccination significantly reduces the protective effect of the vaccine
.

German scientists discovered as early as 2011 that subjects who were deprived of sleep on the night of vaccination had only half of the antibodies and specific T cells of those who had normal sleep one year after the vaccination
.
Therefore, it is advisable to rest early a few days before and after the vaccination, fall asleep early, and never stay up late
.
Shift workers choose to be vaccinated during the off-night shift
.

2.
Pay attention to rest before and after vaccination to avoid fatigue

In order to allow the body to focus on the immune response, unless otherwise necessary, vigorous exercise can be temporarily stopped within two or three days before and after the vaccine, but aerobic exercise can be maintained
.
Under the premise of adequate rest and no adverse reactions, resume high-intensity exercise after two days
.
In the same way, overtime work can also be reduced to avoid physical fatigue and stress
.

3.
Stop hunger and diet, eat three meals well

The immune response is stimulated by the vaccine, and sufficient antibodies are produced, and a variety of nutrients are required
.

Among them, protein is the most important.
The antibody itself is made of protein.
Cytokines and complement are also proteins
.
A variety of B vitamins act as coenzymes and participate in the synthesis of immune factors and antibodies
.

Vitamin A and Vitamin C are necessary for the normal functioning of the immune system
.
The immune stimulation process will increase the consumption of vitamin C, so it is best to supplement it
.
When vitamin D is insufficient, the immune system becomes dysfunctional, and the risk of severe infectious diseases and death increases
.

Zinc is involved in the immune response, and the immune system functions when iron is insufficient
.
The immune response consumes energy, so the total calories of the three meals should be sufficient
.
In addition, in order to protect the body during the inflammatory response, a variety of antioxidants are needed
.
Vegetables, fruits and grains are also essential
.
Therefore, before and after the vaccine, you must eat well
.
Otherwise, the production of antibodies is insufficient, and the effectiveness of the vaccine will be compromised
.

4.
Supplement protein and micronutrients moderately

If you are not confident enough about your nutritional foundation, you can consider appropriately increasing your nutritional supply and taking vitamin and mineral supplements before vaccination
.
For example, people who used to eat less protein food can increase the supply of fish, egg, milk and soy products in advance
.
People who don’t have enough daily vegetables and fruits can eat more fresh fruits and vegetables.
They can also take two to three hundred mg vitamin C tablets every day.
This amount is safe
.
It is also possible to take one compound nutrient supplement every day before and after the vaccination
.

5.
Eat seafood and fresh seafood and other foods with risk of allergies carefully

Because vaccination causes the immune system to stimulate, the reaction to some common allergen foods may also change
.
For some people who are more sensitive, people who are not allergic to seafood and fresh seafood may have a temporary allergic reaction
.
So although most people are fine with eating these foods, it is safer not to eat them for the sake of insurance
.
In addition to seafood and fresh seafood, if you have ever experienced allergic reactions to daily foods such as buckwheat, pineapple, lamb, and eggs, you should also avoid eating them at this time
.

6.
Avoid foods that cause excitement

Coffee and strong tea will affect rest, and excessively spicy and stimulating food will also excite the body, which may not be conducive to achieving the best immune response
.
Of course, if you are accustomed to drinking tea and coffee daily, it will not cause excitement and insomnia, you can drink it normally
.
People who are accustomed to eating spicy food have adapted to these ingredients and do not have to stop eating spicy food suddenly
.

7.
Limit foods that may increase inflammation

Inflammatory factors are produced in the immune response, and excessive inflammation can damage body tissues
.
Therefore, foods that promote inflammation should be reduced at this time
.
Fried, smoked and grilled foods and processed red meat products are rich in pro-inflammatory factors and should be avoided at this time
.
Excessive intake of high-saturated fatty acid foods such as beef and mutton, and excessive intake of sweets and sweet drinks can also promote inflammation
.
Therefore, the quantity of these foods should be controlled
.

8.
Eat fresh fruits and vegetables and whole grains every day

These foods can help supply enough antioxidants and multivitamins, which are necessary to ensure a stable and healthy immune response
.

9.
Avoid alcohol and take drugs with caution

Past experience believes that drinking alcohol after vaccination may interfere with the immune response or aggravate the adverse reactions after vaccination
.
Immune reaction products such as antigen-antibody complexes need to be processed and decomposed by the liver and then discharged into the intestines for clearance
.
Immune stress will increase the burden on the liver, and drinking alcohol will also increase the burden on the liver
.
To be on the safe side, do not drink alcohol for a few days before and after the vaccination
.
Some drugs may also interfere with the immune response
.

I wish you all feel good after being vaccinated, and hope that the epidemic will end soon!
