Types and mechanisms of vaccines Quiz

They introduce live, weakened viruses into the body.

Inactivated vaccines use killed pathogens to trigger an immune response.

Live attenuated vaccines introduce weakened viruses into the body.

Subunit vaccines contain purified components of pathogens; Hepatitis B vaccine is an example.

Adjuvants are added to some vaccines to boost the immune response.

Toxoid vaccines stimulate an immune response to toxins released by pathogens.

Aluminum salts are a common adjuvant used in vaccines to enhance their effectiveness.

Toxoid vaccines may need booster doses to sustain immunity.

Subunit vaccines often require adjuvants for improved efficacy.

The influenza nasal spray vaccine is a live attenuated vaccine.

Live attenuated vaccines usually need cold storage to preserve their stability.

The MMR vaccine is a live attenuated vaccine.

Subunit vaccines consist of purified components of pathogens.

Subunit vaccines often require adjuvants for improved efficacy.

The HPV vaccine is a subunit vaccine.

Inactivated vaccines cannot cause the disease they provide protection against.

The rabies vaccine is an inactivated vaccine.

The BCG vaccine against tuberculosis is a live attenuated vaccine.

mRNA vaccines utilize synthetic mRNA to trigger an immune response.

DNA vaccines can be rapidly produced in response to emerging pathogens.

Polysaccharide vaccines often need multiple doses to establish immunity.

Recombinant vector vaccines utilize a harmless vector to deliver genetic material from the pathogen.

Conjugate vaccines stimulate the formation of immunological memory.

DNA vaccines utilize pathogen DNA to trigger an immune response.

The Adenovirus-vectored Ebola vaccine is a recombinant vector vaccine.
