Can people who are allergic to penicillin, cephalosporin, or ofloxacin get the COVID-19 vaccine? Answer from Guangdong Centers for Disease Control

People's Daily Online, Beijing, June 25 (Zhang Wenting) Today, more than 1.1 billion doses of COVID-19 vaccines have been administered nationwide, and the "Great Wall of Immune System" is being built at an accelerated pace. However, some people still have doubts about vaccination. For example, whether certain substances in the COVID-19 vaccine will harm the brain, whether people with drug allergies can get vaccinated, and other questions are emerging one after another. In response to the above questions, Guangdong CDC gave detailed answers.

Will aluminum adjuvant nanoparticles in the new crown vaccine cross the blood-brain barrier and cause brain damage?

Safe for human body

Recently, there have been rumors that the aluminum adjuvant nanoparticles in the new crown vaccine will cross the blood-brain barrier and cause brain damage. Is this true? In response, Guangdong CDC said that the role of the aluminum adjuvant contained in the new crown vaccine is to enhance the immunogenicity of the vaccine, that is, to enhance the body's immune response to the vaccine. The aluminum adjuvant content of the vaccine is very low, far lower than the amount the human body ingests from food, and is safe for the human body. The diameter of the aluminum hydroxide (or aluminum phosphate) particles in the vaccine is far from the level of "nanoparticles" and it is impossible to cross the blood-brain barrier. Even if a very small amount of aluminum adjuvant enters the blood circulation, most of the aluminum that enters the body will be quickly excreted.

Can people who are allergic to penicillin, cephalosporin, and ofloxacin get the new coronavirus vaccine?

Can

So, can people who are allergic to penicillin, cephalosporin, and ofloxacin get the COVID-19 vaccine? Guangdong CDC said that people who are allergic to the active ingredients of the vaccine, any of the inactive ingredients, or substances used in the production process, or those who have had severe allergies when receiving similar vaccines before, are not recommended to get vaccinated. Since the COVID-19 vaccine currently in use does not contain penicillin, cephalosporin, or ofloxacin, people who are allergic to the above ingredients can get vaccinated.

If I briefly stayed in a shopping mall where a close contact works, should I get a nucleic acid test first or get vaccinated first?

Do nucleic acid test first

If you have an appointment for vaccination, but find that you have briefly stayed in a shopping mall where a close contact works, should you do a nucleic acid test first or get the vaccine first? In this regard, Guangdong CDC recommends that you do a nucleic acid test for the new coronavirus first, and then get the new coronavirus vaccine. In case the nucleic acid test for the new coronavirus is positive, the vaccine cannot be given for the time being. If you need to do a nucleic acid test for the new coronavirus after receiving the new coronavirus vaccine, you can only take samples for testing the day after the vaccination.
