Lecture on the use of vaccines during pregnancy

Pregnancy is not a good time to be vaccinated. But sometimes vaccinations are required because the disease is abundant (fluid) or the pregnant woman has to go to an epidemic area.

When vaccinating, you need to meet the following requirements:

Germs that are still alive are not allowed to be introduced into the body.

Do not give a pregnant woman a fever as a fever can cause the fetus to die.

For live virus vaccines, they are not recommended during pregnancy, but have never been seen to cause fetal malformations even in early pregnancy. So if you have accidentally used these vaccines, there is no indication for abortion.

The vaccines are definitely not dangerous

Tetanus vaccine

The tetanus vaccine is a pure adsorption vaccine. The vaccine is not only not dangerous but is also indicated for use by pregnant women in countries with many neonatal tetanus, including Vietnam. Vaccine is injected intramuscularly, 0.5ml each time.

Pregnant women who have not been completely vaccinated against tetanus: 2 injections given 1 month apart, the second shot must be given at least 1 month before delivery to be effective (should be injected in the second quarter of pregnancy).

The previous delivery had given 2 injections or only 1 injection, this time less than 5 years from the previous birth, only 1 injection is enough (should be injected in the second quarter).

Pregnant women who have been expanded vaccinated at the time of giving birth 3 doses of diphtheria, tetanus, pertussis (the age of expanded immunization in our country is now at the beginning of childbearing age), only 1 dose is enough (should be injected in the second quarter).

Pregnant women have been vaccinated with 5 doses of tetanus prevention: no additional injection is required because with 5 doses, the protection capacity reaches 95% and for a lifetime.

In areas with difficult pregnancy management, 2 doses of tetanus prevention vaccination can be organized for all women aged 18-35 years old.

Vaccine against hepatitis B

Hepatitis B vaccine is an inactivated vaccine that does not pose any danger to the mother or fetus. The vaccine can be given to pregnant women at high risk for hepatitis B.

Flu vaccine

The flu vaccine is not dangerous and can even be used for people with respiratory failure. Flu can cause miscarriages or malnutrition.

Vaccine against polio Salk - Lepine

The vaccine against polio Salk - Lepine is the inactivated virus vaccine. Use late in pregnancy allows the protection of the new-born in the early months of pregnancy.

Vaccines are definitely contraindicated

These are live virus vaccines:

Vaccine to prevent oral polio (Sabin).

Vaccine against rubella (Rubella).

Measles, mumps, and chickenpox vaccines.

A vaccine to prevent diphtheria, pertussis, typhoid because it causes fever in pregnant women.

Vaccines are used in some circumstances

Inactivated rabies vaccine: a vaccine obtained from cell culture. Use this vaccine when needed (if bitten by a rabid dog or suspected rabid dog).

Cholera vaccine: unstable effect, can be used when entering the epidemic area.

BCG: not indicated during pregnancy, nor does it cause complications. If necessary, people use antibiotics and chemicals for treatment.
