Heterogeneous vaccination refers to the use of a different type of vaccine than the primary vaccine when administering a booster dose of the NeoCrown vaccine.
In other words, no matter how many doses or what type of New Crown vaccine you have received, when you receive a booster shot, you choose a different vaccine than the one you received before, and use a “mixed vaccination” to administer the booster shot. This “mixing” method is called sequential vaccination, and vaccinating with different types of vaccines is called heterogeneous vaccination.
The different types of vaccines are called heterologous vaccines. For new vaccine types, there are inactivated vaccines, adenovirus vector vaccines, and recombinant protein vaccines. Antibody production and cellular immunity are observed by laboratory analysis of the immunogenicity of the vaccine. The antibody level activity of 2 doses of inactivated vaccine followed by a third dose of mixed vaccine is higher than that of the third dose of inactivated vaccine from the same source.
It is recommended that everyone responds positively to the booster vaccination, which plays an important role in strengthening the antibodies to the new coronavirus, and is more capable of resisting the chances of viral infection, so as to improve the prevention and control measures of the epidemic in a more effective way.
