What are the consequences of a single injection of the novel coronavirus vaccine? Can tetanus be inoculated Please know this knowledge( Attachment: the second dose of Xinguan vaccine (doggerel)

We need to know the changes of novel coronavirus vaccination

.

In recent years, there have been some new changes in the work of novel coronavirus vaccination, and many people have raised some new questions

.

Here are the answers

.

Why don’t children get the novel coronavirus vaccine? China’s new coronavirus vaccine is safe and effective

.

People should be vaccinated

.

According to the vaccination guidelines, people over the age of 18 can be vaccinated

.

The elderly are also recommended

.

In the real world, the current maximum age of vaccination is 107

.

At this stage, children have not been vaccinated with new coronavirus vaccine because there is no clinical research data on children’s vaccination

.

In the absence of safety and effectiveness data support, children have not been vaccinated with new coronavirus vaccine in the world

.

Can tetanus antitoxin allergy be vaccinated with novel coronavirus vaccine? Tetanus antitoxin (tetanus antitoxin) is used to prevent and treat tetanus

.

The product contains specific antibodies, it is passive immunity, belongs to biological products, but does not belong to vaccines

.

Therefore, tetanus antitoxin allergy is not a contraindication of novel coronavirus vaccination, can be vaccinated with novel coronavirus vaccine

.

After vaccinating novel coronavirus vaccine appears general reaction, can you vaccinate second shot? After vaccination with the novel coronavirus vaccine, very few people had common adverse reactions, such as local pain at the injection site, fatigue, headache, muscle soreness, fever, swelling, joint pain, nausea, etc

.

After judging as mild general reaction, the second injection can be inoculated normally

.

In case of moderate to severe adverse reactions, please inform the vaccination clinic doctor in time, and determine whether the second dose can be vaccinated after comprehensive evaluation

.

   Is it OK to have only one dose of novel coronavirus vaccine? The researchers found that rather than having some people get the second dose first, it is better to use the limited vaccine to get more people to get the first dose, which can indeed reduce the infection rate of the novel coronavirus in the short term

.

This is because even if a single dose of vaccine does not produce complete immunity, it can at least provide a certain degree of protection

.

But in the long run, only one dose of vaccine has a huge hidden danger – promoting the mutation of the virus

.

The speed of virus mutation is closely related to the immune response of human body

.

The less pressure the immune response gives, the faster the virus adapts

.

If the immunity of some individuals is not enough to inhibit the replication of the virus, it is easy to induce “immune escape” of the mutant virus

.

But the researchers also pointed out that even if the immune protection brought by the first dose of vaccine is not complete, if more people get the first dose first, and then make up the second dose in the recommended way soon, these long-term hidden dangers can be avoided to the greatest extent to become an unfortunate reality

.

Every one of us will be safe only if everyone is safe

.

Is the second dose of the novel coronavirus vaccine more responsive than the first? Monitoring showed that the second injection had less reaction

.

New coronavirus vaccine and other vaccines, after vaccination may appear acid swelling, swelling, pain, pruritus and other general reactions, a very small number of people due to individual differences may appear fever, fatigue, nausea, headache, muscle soreness and other symptoms, generally do not need special treatment, most of them can recover after 2 to 3 days, do not affect the second injection

.

Another situation is that the recipient is in the incubation period or prodromal period of a certain disease at the time of vaccination, and the disease happens coincidentally after vaccination, which has no direct relationship with vaccination, and also does not affect the second dose of vaccination

.

In case of fever or persistent discomfort, seek medical advice in time and report to the vaccination unit

.

According to the monitoring of new coronavirus vaccination, although the incidence of general reaction, abnormal reaction, coupling disease and psychogenic reaction is very low, the second dose is lower than the first dose, and the difference is statistically significant

.

However, if there is an allergic reaction after the first dose of vaccination, the vaccinator should report it to the vaccination unit in time

.

After the investigation and diagnosis of the abnormal reaction, the expert group confirmed that it is the allergic reaction caused by the new coronavirus vaccine

.

This situation belongs to the contraindication of vaccination, and there is no need to vaccinate the second dose

.

What happens if the second dose is advanced or delayed? Will the first shot be wasted? Early inoculation was ineffective, but late inoculation did not affect the effect

.

According to the new coronavirus vaccination technical guidelines (First Edition), the interval between two doses of inactivated new coronavirus vaccine is recommended to be completed as soon as possible within 3 weeks and 8 weeks

.

For the inactivated vaccine, after the first dose, the human body may produce antibodies in a short time, but the antibody titer is not enough to produce a better protective effect, and the duration is also very short

.

Only by re inoculation, the immune system can be stimulated again

.

Due to the existence of the first dose of immune memory, the immune response will be much stronger than the first dose, the antibody level will be greatly increased, and the duration will be greatly prolonged

.

It takes time for the formation of immune memory in the first dose

.

For the inactivated vaccine of new coronavirus, it is generally considered to be 21 days, so the second dose should be inoculated at an interval of not less than 21 days

.

Early vaccination should be regarded as invalid vaccination

.

As for the situation of delayed vaccination, like other vaccines, if the follow-up dose of new coronavirus vaccine fails to be vaccinated on time, the delayed vaccination will not affect the protective effect

.

The guidelines also clearly pointed out that those who did not complete the vaccination according to the procedure should be re inoculated as soon as possible

.

There is no need to restart the immunization procedure, and the corresponding dose can be replanted

.

The first dose will not be in vain, there is no case of “losing all previous achievements”

.

Is it better to be immunized by infection than by vaccine? It is costly to establish immune barrier in natural infection

.

It is not feasible to use natural infection of new coronavirus to establish human immune barrier

.

Vaccines can simulate the role of pathogens, in the case of no infection or disease, so that the body has the immune protection of the pathogen, and vaccines need to go through clinical trials before marketing, only when the protection effect meets certain requirements can they be allowed to go on the market

.

All in all, vaccination with new coronavirus vaccine is the best way to obtain immune protection

.

Is it necessary to vaccinate the new coronal vaccine? Virus mutation has always been a high concern of the state and vaccine research and development units and production units

.

Virus mutation is a global concern

.

From the global monitoring of virus mutation, there is no evidence that virus mutation will make the existing vaccine invalid

.

In any case, the mutated virus is only a part of the vaccine in China, which has been confirmed to have a good protective effect on the prevalent virus strains

.

We should vaccinate the new coronavirus vaccine as soon as possible under the deployment of the country, and quickly establish the crowd immune barrier.
