What happens if the novel coronavirus vaccine doesn’t get a second shot? Is there an optimal interval? What if I can’t make an appointment?

However, “the protection period of the novel coronavirus vaccine is only half a year” and “the second dose of the vaccine in the evening will give up all the previous achievements” are constantly on the Internet

.

Some people say: “I’ll stay up until the summer vacation, because the virus is more serious in winter…” is there any difference in the composition and dosage of the two injections of the novel coronavirus vaccine? What happens if you don’t get a second shot? How long is the interval between two injections better? Have you ever received a shot of Xinguan vaccine in other places? Can you still get a second shot in Shanghai? Come and see the latest authoritative answer of the Municipal Health Commission

.

Is there any difference in the composition and dose of the two injections of the novel coronavirus vaccine? A: according to the current immunization strategy, there is no difference in the composition and dose between the two doses of the novel coronavirus vaccine, regardless of the first and second dose

.

At present, Xinguan vaccines produced by Wuhan Institute of biological products (Wuhan Institute), Beijing Institute of biological products (Beijing Institute) and Beijing Kexing Zhongwei Biological Technology Co., Ltd

.

(Beijing Kexing Zhongwei) of Sinopharm group are used in this city

.

The above three vaccines are inactivated vaccines, and the production process is basically the same

.

Can new coronavirus vaccines from different manufacturers be used instead? A: according to the “technical guidelines for new coronavirus vaccination (First Edition)”, it is recommended to use the inactivated new coronavirus vaccine from the same enterprise to complete the whole process of vaccination

.

In case that the vaccine can not be supplied continuously and the recipients can not be inoculated in other places, the vaccine products of other manufacturers of the same kind can be used to complete the whole vaccination

.

Have you ever received a shot of Xinguan vaccine in other places, can you still get a second shot in Shanghai? A: after one shot, I am back in Shanghai now

.

According to the vaccination records of other places, I can complete the follow-up dose according to the recommended interval (the interval between two doses of new coronavirus inactivated vaccine is recommended to be more than 3 weeks, and the second dose should be completed within 8 weeks as soon as possible)

.

For those who have not completed the vaccination according to the procedure, it is suggested that they should be re inoculated as soon as possible

.

What happens if you don’t get a second shot? A: the immune procedure of the vaccine is determined based on the results of research and development stage and clinical trial stage, so as to obtain the best safety, immune response effect and immune persistence

.

It is difficult to obtain the best immune response effect and immune persistence without complete vaccination

.

After the first injection, is it important to make an appointment for the second injection? A: at present, it is recommended that the best interval between two doses of vaccine is 3 to 8 weeks

.

Vaccination sites will reasonably arrange the time of the second dose according to the supply of vaccine and the time of each person’s first dose

.

Don’t worry if you can’t make an appointment for the time being, because in the range of 3 to 8 weeks, the effect is guaranteed

.

Please be patient

.

After the first injection, symptoms, can you play a second injection? A: let’s list several cases

.

The first is after vaccination, just in time to catch a chronic attack or suffering from a cold, herpes and other acute diseases

.

For this kind of situation, we should first control and treat the disease

.

When the attack period is over, or the chronic disease control is stable, we can continue to receive the second injection

.

The second is the first dose of vaccination after fever, mild rash and other adverse reactions

.

From the results of previous clinical trials and information collected during the use of novel coronavirus vaccine, the occurrence of common adverse reactions of novel coronavirus vaccine is basically similar to other vaccines that have been widely used

.

The main causes were swelling, induration, pain, fever, fatigue, nausea, headache, muscle soreness, etc

.

Usually this kind of reaction will disappear with the passage of time, without special treatment, the second injection can also be inoculated as usual

.

Different people have different situations

.

Of course, if you feel that you can’t eat properly, you can tell the doctor at the vaccination site whether you can get vaccinated or not

.

How long is the interval between two doses of vaccine better? A: on March 29, 2021, the National Health Commission issued the “technical guidelines for new coronavirus vaccination (First Edition)”, which recommended that the interval between two doses of basic immunization with inactivated new coronavirus vaccine should be 3-8 weeks (21-56 days)

.

Vaccination sites will reasonably arrange the time of the second dose according to the supply of vaccine and the time of each person’s first dose

.

In February and March last year, some vaccine developers had been vaccinated with the novel coronavirus vaccine

.

How about the antibodies in the human body? A: in fact, it’s less than a year since the development of novel coronavirus vaccine

.

As time goes on, the data will be updated at any time

.

In March last year, some people, as the “vanguard” of the vaccine, have been inoculated with the novel coronavirus inactivated vaccine, which has now been on the market

.

Vaccine enterprises have carried out clinical monitoring

.

Up to now, more than nine months of antibody detection data have been obtained

.

The data show that the antibody still remains at a certain level, and the follow-up monitoring will continue to strengthen to further observe the maintenance time of the antibody

.

Would you like to call later? A: only when the number of vaccinated individuals reaches a certain proportion can the protection of the group be formed, that is, to form a population immune barrier, to protect individual people who cannot be vaccinated due to vaccination taboo and other reasons, as well as a small number of people who have not been protected after vaccination

.

If everyone delays vaccination, the immune barrier will never be established

.

If you vaccinate quickly, this barrier may come a day earlier

.

To get back to normal life as soon as possible, vaccine is the best choice at present
