Can the new crown vaccine be used?

To clarify these issues, we first need to understand what kinds of new coronavirus vaccines are included?

At present, China’s approved new coronavirus vaccines for conditional marketing or emergency use include 5 types, of which 3 are new coronavirus inactivated vaccines, referred to as Sinopharm, Beijing Kexing and Wuhan Biology; one is an adenovirus vector vaccine, produced by Kangxi Produced by Nuo Biological Co.
, Ltd.
, referred to as Cansino, the other is a recombinant new coronavirus subunit vaccine, referred to as Anhui Zhifei
.

In 2021, my country's assisted reproductive technology experts issued the "Expert Recommendations on the New Coronavirus Vaccination of People Preparing for Pregnancy and Assisted Reproductive Technology", suggesting:

1.
For women preparing for pregnancy, in view of:

① Women are immunosuppressed after pregnancy and are susceptible to pathogens;

②The new coronavirus may cause histopathological changes by infecting the placenta, which may increase the risk of fetal death, premature delivery and accompanying complications during pregnancy;

③In clinical trials of the new crown vaccine, pregnant women were excluded.
There is no evidence on the effectiveness and safety of the new crown vaccination during pregnancy.
It is recommended that women receive the new crown vaccine before pregnancy
.

2.
For pregnant and lactating women, although data on immunogenicity and safety after vaccination are currently being collected, there is still a lack of application data for pregnant women.
Therefore, it is recommended that pregnant and lactating women not be vaccinated
.

The recommendations of the International Society for Reproduction believe that inactivated vaccines and toxoid vaccines are safe to use during pregnancy, while live attenuated vaccines can infect the fetus through the placental barrier.
Avoid vaccination during pregnancy.
If you find that you are pregnant after vaccination, Termination of pregnancy is not recommended
.

In summary, the following four suggestions are given for women in different periods:

1.
It is not recommended to vaccinate for women who know that they are pregnant
.

2.
For those who are pregnant after vaccination or vaccinated when the pregnancy is unknown, it is not recommended to terminate the pregnancy just because of the new coronavirus vaccine.
It is recommended to do a pregnancy check and follow-up
.

3.
For women who are preparing for pregnancy, it is not necessary to delay pregnancy planning just because of the new coronavirus vaccine
.

4.
It is recommended to vaccinate breastfeeding women (such as medical staff, etc.
) who are at high risk of new coronavirus infection
.

In addition, men do not have the problem of being unable to get the new crown vaccine due to pregnancy
