Recently, news about vaccines has continued: the state announced that the new crown vaccine is free for all people, and Shanghai has completed the emergency vaccination of 602,000 people with the new crown vaccine… Yesterday, the data of “the protective efficacy of domestically produced new crown vaccine is 79.34%” has once again aroused everyone’s discussion.
What does protection effectiveness 79.34% mean?
This means that after vaccination, our probability of contracting the new coronavirus has decreased by 79.34%.
Seeing that more and more people are vaccinated with the new crown vaccine, and there are various reliable and unreliable rumors, you may have a lot of questions:
Do I need to worry about side effects when I get a vaccine?
Can other vaccines be given during the vaccination period?

Are you vaccinating the new crown vaccine now as a mouse?
The inactivated vaccines currently used are very safe! The current inactivated vaccines used for emergency vaccination have already passed two rounds of complete clinical studies on mice, various other animals, and many people, so there is no way to talk about mice. There is no need to worry too much about side effects. According to the official news from the press conference of my country’s joint prevention and control mechanism: The current adverse reactions after vaccination are mainly local pain and induration. Less than 0.1% of mild fever cases and only about 2/100 cases of severe adverse reactions Million (and not necessarily related to vaccines).Since the vaccine entered clinical research, although there have been reports of fever, fatigue, allergies, facial paralysis, transverse myelitis-like symptoms, and even death after vaccination, we should be clear: After vaccination, minor adverse reactions are normal. As for those serious adverse reactions, investigations by professional institutions have found that one part is not clearly related to the vaccine, and the other part has been relieved after treatment. As for death, the current description is more sensational, and there is no clear evidence that it is related to the vaccine.

How long will it take for the vaccine to work? How long will it last?
More detailed data has not been released on the public platform, but based on the results of phase I and phase II clinical studies, most people will produce enough protective antibodies about 2 weeks after the completion of the 2 doses of vaccination. As for how long the protective effect of the vaccine can last, there is no clear answer for the time being. After all, the vaccine development time is less than one year, and there is very little information on immunity persistence. However, according to official information, after 2 doses of vaccine, neutralizing antibodies can last for more than half a year. I believe that with the deepening of research, this number will continue to extend.
No longer need to do nucleic acid testing after being vaccinated?
I want to get the new crown vaccine, how should I get it?
The vaccine used for emergency vaccination requires 2 doses with an interval of 14-28 days. However, according to the national “Notice on Promoting the Vaccination of New Coronavirus for Key Populations”: At this stage, the new coronavirus vaccination is only open for key occupational groups for epidemic prevention and those who really need to work abroad. At present, vaccinations in most areas are uniformly notified by the unit and go to officially approved vaccination institutions for vaccination. With the orderly advancement of epidemic prevention work and more abundant vaccine supplies, the scope of the vaccine population will be gradually expanded in the future.
