Answer:
True
Explanation:
everything is composed of cells Dead or Alive
Answer:
Antigen, stabilizers, surfactants, diluents, preservatives
Explanation:
- Antigen: This is part of the protein structure virus or part of its genetic material. These parts are active. But sometimes, the inactivated form of the virus is also included in the vaccine.
- Stabilizers: Avoid other chemical reactions occurring in the interior of the vaccine.
- Surfactants: They prevent the occurrence of sedimentation and agglutination of the elements inside the vaccine.
- Diluent: Used to dilute the vaccine in an appropriate concentration before being used.
- Preservatives: As the word says, preservatives avoid any possible contamination of the vaccine. These elements´ use depends on the doses prepared. If it is only for one-person use, then they are not needed. But if the doses are to be used by more than one person, they need preservatives because once the vaccine is opened it is vulnerable to contamination.
