What type of vaccine is Prevnar 13?

Conjugate vaccine
Live attenuated vaccine
Inactivated vaccine
Subunit vaccine

The correct answer is: Conjugate vaccine

Prevnar 13 is a conjugate vaccine. This type of vaccine is created by binding a non-toxic part of the pathogen (pneumococcal antigen in this case) to another molecule. This allows the immune system to recognize and produce antibodies against the pathogen, providing protection against future infections. The incorrect options are - B: Live attenuated vaccines contain weakened or non-pathogenic strains of the virus or bacteria, which may not be suitable for individuals with weakened immune systems. - C: Inactivated vaccines use the killed virus or bacteria, which may not be as effective as live attenuated vaccines in terms of immune response. - D: Subunit vaccines use only a specific part of the pathogen, such as a protein or sugar, which may not provide enough immunity compared to a full pathogen in a live or killed form.
