How long can I get the new crown vaccine after taking other vaccines?

Columnist/Sun Guihua

The question of the interval between different types of vaccinations, you will understand after reading this article.

Since the new crown epidemic, our country has invested a lot of manpower, material and financial resources to protect the health of the people and adopted a series of prevention and control measures to stop the spread of the epidemic.

On May 28, the official website of the Chinese Center for Disease Control and Prevention announced the monitoring of adverse reactions to the new crown vaccination in my country.

The interpretation of its monitoring information shows that the general response and abnormal response rates of my country's new coronavirus vaccine are lower than the average reported levels of other types of vaccines in my country in 2019.

The results once again proved that my country's new crown vaccine is safe and effective.

We encourage all eligible people to actively participate in vaccination, but in the actual vaccination process, many people, including vaccination doctors, still have questions about the interval.

About the vaccination interval

Chinese disease control experts have 4 suggestions

In response to similar issues, the CDC experts clearly stated:

1.

2.

3.

4.

Pay attention to the "before" and "after" of vaccination

The author takes the rabies vaccine as an example to further illustrate the importance of the interval between new crown vaccination.

First, if you vaccinate the new crown first, you need to vaccinate rabies vaccine and tetanus serum without considering the interval to inject immediately.

2.

3.

That is to say, the interval should be considered when vaccinating rabies and tetanus toxoid before other vaccinations; if you want to vaccinate rabies and tetanus, then regardless of what you vaccinate before, regardless of the interval, vaccinate immediately.

Vaccines do not immediately produce antibodies

Intermediate process that requires an immune response

Why are these requirements? This question is related to how the vaccine works in the body.

Vaccines don’t allow the body to produce antibodies immediately after injection.
Vaccines work through the interaction of the human immune system.
It takes a certain period from injection to production of antibodies, and there is an immune response process in the middle.

The process is divided into three stages:

First, the recognition period

Lymphocytes recognize foreign antigens, that is, vaccines.

Second, the activation period

Lymphocytes are antigens, and the new crown vaccine is activated at this time.

Third, the effective period

Lymphocytes produce antibodies to clear the antigen, which is the infected new coronavirus.

Antibodies are generally produced 7 days after the first dose of the new crown, and the positive rate is 60%-90% from 14 to 28 days.
The positive rate of antibodies is more than 90% 28 days after the second dose.

After clarifying these problems, both the vaccinator and the vaccinating doctor should pay enough attention to the interval between vaccines.

The interval is short.
During the period of vaccine detoxification and the establishment of a new immune response, vaccination of another vaccine will easily affect the immune response, causing physical discomfort or reduced immunity, which will affect the production of antibodies between the vaccines, and thus affect the immune effect, so I would like to remind everyone:

When vaccinating the new crown vaccine, you must pay attention to the interval before and after, and you cannot change the vaccination procedure yourself.
