Do people over 60 years old suggest getting the third injection of COVID-19? How long can I get pregnant after COVID-19 booster injection

Up to now, 100 million people in China have been vaccinated with COVID-19 vaccine, and COVID-19 vaccine is also free, so many people are willing to vaccinate to give themselves a guarantee. Recently, the National Health Commission released the first version of the COVID-19 Vaccination Technical Guide. How long can you get pregnant after COVID-19 Vaccination? The small edition is organized as follows:

1. Release of Technical Guidelines for COVID-19 Vaccination

1. Applicable target

people aged 18 years and above.

2. Inoculation times and intervals

(2.1) 2 doses of inactivated COVID-19 vaccine (Vero cell) [SEP]; The recommended interval for vaccination between two doses is 3 weeks, and the second dose should be completed as early as possible within 8 weeks.

(2.2) One dose of recombinant COVID-19 vaccine (adenovirus type 5 vector) [SEP].

(2.3) Three doses of recombinant COVID-19 vaccine (CHO cells) [SEP]; The recommended interval for vaccination between adjacent doses is 4 weeks. The second dose should be completed within 8 weeks after the first dose, and the third dose should be completed within 6 months after the first dose.

3. Vaccination route and site

recommends intramuscular injection into the deltoid muscle of the upper arm.

4. Vaccination recommendations for specific populations

(4.1) People aged 60 years and above

People aged 60 years and above are people with high risk of serious illness and death after COVID-19 infection. At present, the number of people included in the phase III clinical trials of four conditionally approved COVID-19 vaccines is limited, and there is no data on the protective effect of vaccines on this population. However, phase I/II clinical research data shows that the safety of vaccination in this population is good. Compared with the 18-59 age group, the titer of neutralizing antibodies after vaccination is slightly lower, but the positive conversion rate of neutralizing antibodies is similar, indicating that the vaccine also has a certain protective effect on the population over 60 years old, and it is recommended to be vaccinated.

(4.2) The current vaccines available for the population under 18 years old have not yet obtained clinical trial data for this population, and it is not recommended to vaccinate the population under 18 years old at this time.

(4.3) Chronic patient group

Chronic patient group refers to the group with high risk of severe disease and death after COVID-19 infection. The group of chronic patients with stable health and good drug control is not considered as the contraindication group for COVID-19 vaccination, and vaccination is recommended.

(4.4) Individuals with impaired immune function.

The population with impaired immune function is the population with high risk of severe disease and death after COVID-19 infection. At present, there is no data on the safety and effectiveness of the COVID-19 vaccine for this population (such as patients with malignant tumors, nephrotic syndrome, AIDS), and people infected with human immunodeficiency virus (HIV). The immune response and protective effect of this population after vaccination may decrease. For inactivated vaccines and recombinant subunit vaccines, it is recommended to administer them based on the safety characteristics of similar vaccines in the past; For adenovirus vector vaccines, although the vector virus used is replication defective, there is no safety data for the use of similar vaccines in the past. It is recommended that individuals be fully informed and weigh the benefits over the risks before administering.

(4.5) Previous COVID-19 patients or infected persons.

The existing research data shows that the re infection of COVID-19 is rare within 6 months after infection. People who have been infected with COVID-19 virus in the past (patients or asymptomatic infected people) can be given one dose after 6 months on the basis of full notification.

II. How long can I get pregnant after COVID-19 vaccination?

If you are pregnant after vaccination or vaccinated in the case of unknown pregnancy, based on the understanding of the safety of the above vaccines, it is not recommended to take special medical measures (such as termination of pregnancy) only for the purpose of COVID-19 vaccination, and it is recommended to do a good job in pregnancy inspection and follow-up. For women with a pregnancy preparation plan, it is not necessary to delay the pregnancy plan just because of the COVID-19 vaccine.

Although there is no clinical research data on the impact of COVID-19 vaccination on breast-feeding infants among lactating women, based on the understanding of vaccine safety, it is recommended to vaccinate lactating women (such as medical staff) with high risk of COVID-19 infection. Considering the importance of breast-feeding for infant nutrition and health, and referring to international practices, it is recommended to continue breast-feeding after breast-feeding women are vaccinated with COVID-19 vaccine.
