There is no such thing as which new crown vaccine is better. There are three types of new crown vaccines, namely inactivated vaccine, adenovirus vector vaccine and recombinant subunit vaccine, all of which are able to provide good protection to the body after vaccination.
1. Inactivated vaccine: Inactivated vaccine is a vaccine prepared by culturing and inactivating the virus in vitro, and requires two doses of vaccination. the interval between two doses of vaccination should be not less than 3 weeks, and the second dose should be completed as early as possible within 8 weeks, and a booster dose can be given 6 months after the second dose of vaccination. Inactivated vaccines usually have fewer adverse effects and are suitable for people who live in the local area for a long time.
2. Adenovirus vector vaccine: adenovirus carrying nucleic acid fragments of the new coronavirus is delivered to the cells to express the antigen, and 1 dose is given, followed by a booster dose at 6 months of age. The vaccination is more efficient.
3. Recombinant subunit vaccine: through genetic engineering methods, the virus protein is specifically expressed in vitro, and then prepared into a vaccine and injected into the human body. The whole process requires three injections, and the interval between two injections needs to be more than 4 weeks. The vaccination time is long and safe.
It is recommended that people who have not received the New Crown vaccine should complete the New Crown vaccination at a hospital or vaccination center as soon as possible.
