What is the difference between COVID-19 vaccine booster needle and basic needle?

1, the antibody produced by enhancing immunity has stronger endurance.

After half a year of intensive immunization, although the antibody level has also decreased, it is still higher than the peak after two or one doses of vaccine. All these suggest that strengthening immunization will have a better protective effect.

2. The antibody spectrum is also wider.

Related studies show that strengthening immunization can not only increase antibodies, but also broaden antibody spectrum, which means better protection for mutant strains.

Different COVID-19 vaccines have different basic immunization time. The basic immunization of adenovirus vector COVID-19 vaccine in China only needs 1 needle; Recombinant protein subunit vaccine needs to be inoculated with 3 shots within half a year; Inactivated vaccine in China and mRNA vaccine in the United States need 2 needles.

Intensive immunization refers to vaccinating the same vaccine again after the basic immunization is completed for a period of time. Most people in China are vaccinated with inactivated COVID-19 vaccine. In this case, the third dose of vaccine is a booster immunization.

What are the precautions for strengthening immunization?

Bring your previous vaccination certificate and ID card before vaccination.

Strictly avoid contraindications. If allergic reaction occurs after vaccination with COVID-19 vaccine, no matter whether it is the first injection or the second injection, as a contraindication, booster injection cannot be performed.

After inoculation, you need to stay in the same place for at least 30 minutes. A few people will have mild systemic reactions, such as tenderness at the inoculation site, fever, headache, body aches, etc., and generally do not need to go to the hospital. Pay attention to rest, and generally relieve yourself in 1-2 days. However, if the symptoms are serious and last for a long time, it is recommended that the recipient go to the hospital for treatment in time.
