Is the inactivated COVID-19 vaccine really safe? The powerful motherland gives you the most reliable answer

As COVID-19 spreads around the world, every country has launched vaccine research. Currently, many COVID-19 vaccines have been approved for marketing, and my country has also begun large-scale COVID-19 vaccination work.

Today, Yaowa will take you to learn about this vaccine~

Is the inactivated COVID-19 vaccine effective? Efficacy based on data

According to the results of clinical trials, after the two shots of the inactivated COVID-19 vaccine in my country were completed, the neutralizing antibody positive conversion rate was 99.52%. This means that among those who received two shots of the vaccine, 99.52% of the subjects produced neutralizing antibodies. The vaccine's protection against diseases caused by COVID-19 infection is 79.34%, which means that 79.34% of the subjects were protected from infection because of the vaccine. This figure is much higher than the standard of no less than 50% proposed by the World Health Organization. And given the current status of the COVID-19 process in my country, the vaccine is fully capable of meeting the requirements for epidemic prevention and control.

Is the COVID-19 inactivated vaccine safe and reliable? The number of people vaccinated gives the answer

Compared with other types of vaccines abroad, the COVID-19 inactivated vaccine developed in my country has advantages that cannot be ignored. It is safer and easier to store and transport. At present, countries around the world have successively vaccinated various approved vaccines, and the vaccine developed by our country has been vaccinated by more than 10 million people in China alone, the largest number of vaccinations in the world. And so far, no serious adverse reactions have occurred. This also proves that the vaccine developed by our country is fully safe, effective and reliable.

I heard that the vaccine was a virus? Inactivated virus vaccines are very common

The inactivated COVID-19 vaccine widely used in my country this time is an inactivated virus vaccine. It refers to a biological preparation that first cultivates the virus or bacteria, then kills the pathogenic microorganisms by physical and chemical methods, but still maintains its immunogenicity. Inactivated viruses are very common, such as rabies vaccines, influenza vaccines, etc., which are inactivated virus vaccines, so there is no need to panic.

1. The inactivated COVID-19 vaccine is made with viruses, but it should be noted that inactivated vaccines kill all viruses, so the inactivated COVID-19 vaccine does not contain live viruses.

2. What maintains the immunogenicity of the vaccine are some viral antigens or pathogen polysaccharides, which can stimulate the body's immune response, produce antibodies and memory cells for secondary immunization.

3. The current age limit for inactivated COVID-19 vaccination is 18 to 59 years old.

Is it difficult to get the inactivated COVID-19 vaccine? Community hospitals can get it

For COVID-19 inactivated vaccines, you can consult the community health service center or medical institution near your place of residence. After understanding the various precautions for vaccination, make an appointment for vaccination. When you are vaccinated, you only need to bring your personal ID card to the vaccination site.

You must be observed on the spot for 30 minutes after vaccination. You should drink plenty of water and rest more after vaccination. Keep the vaccination site clean and hygienic, do not wash or squeeze it, to prevent infection at the vaccination site. It is generally not recommended to take a bath on the same day to prevent discomfort caused by cold. In addition, it is not advisable to drink alcohol within a short period of time after vaccination.

Of course, Yaowa would like to remind everyone to pay attention! The new coronavirus inactivated vaccine needs to be administered twice, with an interval of 14 days between the two doses. Don’t just get one shot!

No vaccine can 100% ensure that the recipient will not be infected, but it can only ensure that the probability of being infected by the virus is greatly reduced. Therefore, after vaccination, you still need to take good personal protection and maintain good hygiene habits. Wear a mask when going out, try to avoid places with a lot of people, and clean and disinfect in time.
