People who are allergic to cephalosporins are generally eligible for vaccination with Neocon. People who cannot be vaccinated with the New Crown virus include those who have had severe allergic reactions during previous vaccinations and those who are allergic to the components of the New Crown vaccine. Cephalosporins are not part of the previous vaccines and the New Crown vaccine does not contain cephalosporins, so it is usually possible to receive the vaccine. Cephalosporin refers to cephalosporins, a generic term for a class of antibacterial drugs commonly used in clinical practice. The New Crown vaccine consists of inactivated New Crown vaccine and adjuvants such as sodium dihydrogen phosphate, disodium hydrogen phosphate, and aluminum hydroxide, etc. People who are allergic to these ingredients are not allowed to receive the New Crown vaccine, but it does not contain cephalosporins, so people who are generally allergic to cephalosporins are not affected by the New Crown vaccine. However, if a cephalosporin allergy has recently occurred, it is necessary to wait until the allergy has completely subsided before a professional assesses whether vaccination is possible to avoid aggravating the adverse reaction. However, it is still recommended that such people explain to the medical staff at the vaccination site before vaccination, so that a professional can make a clear judgment and perform allergen testing if necessary. Do not conceal the actual situation to avoid adverse consequences. It is inappropriate to drink alcohol or consume alcoholic foods both before and after vaccination to avoid triggering or aggravating allergic reactions.
