Does Kexing COVID-19 vaccine need a third shot? Will there be any adverse reactions after receiving the third dose?

It is necessary based on the current epidemic situation. Because according to published research results, two doses of Sinovac vaccine can produce good immune memory, but the duration is not long, and the immune effect will decrease after 6 months, while the third booster shot can increase antibodies tenfold within a week. Why does Beijing Kexing need a third shot? According to published research results, two doses of Sinovac vaccine can generate good immune memory, but the duration is not long. After 6 months, the immune effect will decrease, so a third dose will be introduced. After a few months, the third dose can quickly activate the immune system and produce a large number of antibodies. The results of Sinovac's third dose test have been announced: antibody levels have increased by 3-5 times. On July 26, the official WeChat vaccine benefits of Sinovac Holding Biotechnology Co., Ltd. announced that the inactivated COVID-19 vaccine Kelafu of Sinovac had induced good immune memory, and the neutralizing antibody level significantly improved after the third dose. According to the official news of Sinovac, two doses of the inactivated coronavirus vaccine Kelafu of Sinovac can produce good immune memory. After the third dose is administered from the 28th day to the 8th month after the second dose, the neutralizing antibody level is significantly higher than the baseline level. The adverse events are all Level 1 or Level 2, and there are no related serious adverse reactions. The research results indicate that vaccination with two doses of Kellaifu has good immunogenicity and can induce immune memory in the body; The third dose of Kailaifu has good immunogenicity and safety after vaccination.

When the new coronavirus vaccine was inoculated in the past, if there was an allergic reaction, whether it was the first injection or the second injection, it was a taboo object. Such people were not recommended to take intensive injections, and the on-site doctors would also assess whether it met the vaccination requirements.
