How to cancel the third message of vaccine?

You can call 10086 to ask the staff to cancel the third SMS of the vaccine. At present, COVID-19 vaccines that need three injections in China are generally recombinant protein vaccines. This vaccine needs to be inoculated three times to continuously enhance the immune effect and make the body reach sufficient antibody strength.

The production process of recombinant protein vaccine does not involve live virus, but allows cells to simulate virus to stimulate the production of antibodies in vivo, which is relatively safe. Through the clinical experiment of people aged 18-59, the positive conversion rate of neutralizing antibody reached 83% after two doses of inoculation and 97% after three doses of inoculation.

principle

Vaccine is an active immune preparation made of pathogenic microorganisms (such as bacteria, rickettsia, viruses, etc.) to prevent infectious diseases. ) and its metabolites are artificially attenuated, inactivated or genetically modified. The vaccine retains the characteristics that pathogenic bacteria stimulate the immune system of animals.

When animals come into contact with this harmless pathogen, the immune system will produce certain protective substances, such as immune hormones, active physiological substances and special antibodies. When animals come into contact with this pathogen again, the animal's immune system will follow the original memory and produce more protective substances to prevent the harm of pathogens.
