The protection period of the new coronavirus vaccine is only half a year?

Rumor: Since the COVID-19 vaccination work was carried out on a large scale, the discussion about the vaccine protection period has never stopped. There are rumors that the COVID-19 vaccine protection period is only half a year. Is this true?

Fake rumors

Verification points:

1 The protection period of the new crown vaccine is not only half a year, "half a year" is just the bottom line for qualification and listing. It's just that the vaccination time is still very short, and there is only half a year of data for the time being.

2. There are individual differences in the levels of antibodies produced after COVID-19 vaccination. Some individuals still have high antibody levels in their bodies one year after COVID-19 vaccination, and the vaccine protection period may be underestimated.

April Fools' Day is here, and it's another day when "fooling people is not a crime". However, rumors on the Internet don't care whether it's April Fools' Day or not, and they fool the public every day.

Last month, many rumors appeared on the Internet: the protection period of the new crown vaccine is only half a year, the sun is harmful to televisions and human bodies, and wireless charging will produce extremely strong radiation... On April Fools' Day, we will take stock of the rumors that "fooled" us in March.

1. The protection period of the new crown vaccine is only half a year? The truth: The specific protection period is still under observation. Since the new crown vaccine work has been carried out on a large scale, the discussion about the vaccine protection period has never stopped. There are rumors that the protection period of the new crown vaccine is only half a year. Is this true?

A Science and Technology Daily reporter learned that the "Guidelines for Clinical Evaluation of New Coronavirus Vaccines (Trial)" issued by the National Medical Products Administration requires that the new coronavirus vaccine on the market must provide at least 6 months of protection.

Recently, Pang Xinghuo, deputy director of the Beijing Center for Disease Control and Prevention, said in an interview with the media that the protection period of the new crown vaccine is not only half a year, but the vaccination time is still very short, and there is only half a year of data for the time being. At present, relevant departments are still continuing to collect data on the antibody levels of the vaccinated population and closely monitor the protective efficacy after vaccination.

There is even more exciting news. Yu Qingming, deputy to the National People's Congress and chairman of Sinopharm Group Sinopharm Holdings, revealed at this year's two sessions that in March 2020, the party and government leaders of the group's four-level enterprises "tested the drug on themselves". After one year of continuous antibody tracking and monitoring, their antibody levels are still at a high level and have not shown a significant decline.

Of course, there are individual differences in the level of antibodies produced after COVID-19 vaccination. The above-mentioned case of "testing the drug on oneself" may not be enough to explain anything, but it sends a signal: the protection duration of the COVID-19 vaccine may be underestimated by some people.

To sum up, the rumor that "the protection period of domestically produced new crown vaccine is only half a year" is a rumor. "Half a year" is just the bottom line for qualification and listing. Time will eventually give the answer to how long the protection period is.
