I heard that the reaction will be greater after the sequential booster shot, why don t you take it?

The antibodies produced by the sequential booster CanSino new crown vaccine are 5 times that of homologous booster, and the antibodies against Omicron are 6 times that of homologous booster, so for the current complex epidemic situation, this method of play can still have a relatively strong protective effect.

As for the side effects of the new crown vaccine, it is generally a normal reaction when the vaccine takes effect, and it will generally subside automatically within 48 hours, so there is no need to worry about It is more cost-effective to exchange these reactions that may not necessarily occur for a stronger immune effect, especially if you are planning to go abroad and need a stronger protective effect.

And now that CanSino's new crown vaccine is a vaccine in the WHO emergency use list, you can go abroad directly after vaccination, and you don't have to worry about revaccination when you go abroad.

A large reaction to vaccination does not necessarily mean that it is unsafe, and the new crown vaccines on the market are all after long-term clinical trials, which are still relatively reliable.

The response of the sequential booster CanSino vaccine may be greater than that of the inactivated vaccine, because the CanSino vaccine can stimulate "cellular immunity", which makes the body's immune response greater and more effective.

The reaction after vaccination is related to the individual's physical condition, some people have a reaction, and many more people do not react. However, the general reaction belongs to the body's immune response to the vaccine, which is a normal phenomenon, and it is good to take a break.

Sinopharm Group has designed a booster injection trial when it carried out a phase clinical study last year, and the relevant data has been released recently. In the three age groups of 18 to 59 years old, over 60 years old, and 3 to 17 years old, the vaccination schedule is designed to be 56 days apart from the third and second doses.

The overall safety data is still very good, whether it is a local reaction or a systemic reaction, it is in line with expectations, and there is no difference from the two-shot one. Zhang Yuntao said that in terms of immunogenicity, after the third shot, the increase in antibodies was about 30%.

Although there is no large-scale epidemic, there are still scattered and frequent occurrences, and it is even more difficult to explain abroad, coupled with the rampant mutant virus, so everyone needs the new crown vaccine to provide stronger protection.

Sequential booster is a way to strengthen the protection of vaccines, and its effect has also been proven. For example, the sequential booster CanSino new crown vaccine, the antibody level is 5 times that of homologous booster, and the antibody against Omicron is 6 times that of homologous booster, which is very telling that the sequential booster shot can indeed strengthen the immunity of the new crown vaccine.

1 is a type of booster shot.

Sequential booster vaccination is a new way to get a booster dose of the new coronavirus vaccine, which refers to the use of vaccines with different technical routes to be administered.

At present, the regulations on sequential booster immunization are: people who have completed the 2-dose inactivated vaccination of Sinopharm Sinopharm Beijing Company, Sinopharm Sinopharm Wuhan Company, and Beijing Sinovac Company for 6 months, and are at least 18 years old, can choose Anhui Zhifei vaccine (recombinant protein vaccine) or CanSino vaccine (adenovirus vector vaccine) for sequential booster immunization.

2. It can improve the immune effect of the human body.

According to the relevant experimental data, whether it is sequential booster immunization or ordinary homologous immunization booster shot, it can stimulate the body's immune nucleogenicity and improve the body's immune effect after vaccination, so for people who meet the conditions for vaccination, it is recommended to choose one.

However, according to the research data, the level of neutralizing antibodies produced by sequential booster vaccination is 5 times higher than that of homologous booster vaccination, so relatively speaking, sequential booster vaccination can also obtain better immunogenicity.

3 Injections are required.

Sequential vaccination is only another way of vaccination for booster shots, but the choice of vaccination is different, but it still needs to be injected, and there may be inhaled vaccines that have been successfully developed in the future.

However, sequential vaccination is not a simple "mixed vaccine", but the use of the complementarity of different vaccines to obtain the best immune effect, which can not only have a better immune protection effect on the highly varied virus, but also avoid the occurrence of some ***.

4No, you cannot. Sequential booster immunization is a booster shot, so for people who meet the vaccination requirements, it is enough to choose one of the homologous booster immunization (that is, the third dose of the new crown vaccine) and sequential booster immunization in the original technical route vaccine.

Either technology can further improve the body's immune effect, but if you have already received a booster shot, then according to the current regulations, it is not possible to carry out sequential vaccination.

The sequential booster shot is because the new crown virus is mainly a mutant virus, and the immune effect of the new crown vaccine needs to be strengthened through the sequential booster shot.

Sequential booster shots are to replace the previous inactivated vaccine with a recombinant protein vaccine or CanSino new crown vaccine, and strengthen immunity through the complementary advantages of different vaccines.

The conditions for sequential booster shots are two injections of inactivation + 6 months + 18 years old, both of which are indispensable
