Dengue (Dengvaxia)
What is it?
Dengue Fever is caused by dengue virus and is spread by mosquitos (specifically Aedes aegypti, which is the same type of mosquito that spreads Zika, chikungunya, and yellow fever). There are four different serotypes of dengue, and people can get infected multiple times.
​
Dengue can cause a wide range of symptoms. Sometimes dengue causes almost no symptoms but it can also cause severe disease (severe bleeding and organ failure), which can be deadly.
​
The dengue vaccine (Dengvaxia) is recommended for people 9-16 years old who have previously had dengue (confirmed with a test). Previous infectious is part of the recommendation because people who are vaccinated who have not had dengue before are more likely to have severe infection and require hospitalization. This is due to antibody-dependent enhancement (to learn more, click here).
Sanofi-Pasteur will discontinued production of Dengvaxia in September 2025.

(Janssen)
This is one of the COVID-19 vaccines.
Ingredients:
Active ingredients:
This vaccine uses a version of adenovirus that is modified so that it cannot replicate or make you sick. This modified virus contains genetic material that encodes the spike protein of SARS-CoV-2.
Your body uses this genetic information to create the spike protein, which cannot cause disease on its own, but it acts as an antigen and teaches your body how to respond if it is exposed to the virus in the future. This protein is displayed on the surface of the cell, which prompts the immune system to create antibodies that protect you from future infections.
Inactive ingredients:
Salts: help maintain the stability and pH of the vaccine
Acids: improve the stability of the vaccine

Prevnar13 (PCV13)
This vaccine protects against pneumococcal disease.
It is no longer routinely recommended because there are versions that protect against more serotypes such as PCV15 and PCV20
Ingredients:
Active ingredients:
Purified sugars from the capsule (outside) of 13 serotypes of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). In order to help the vaccine create an immune response, these sugars are conjugated (attached) to a protein from diphtheria called CRM197 carrier protein.
Inactive ingredients:
Amounts are based on a 0.5 mL dose
Adjuvants: strengthen the immune response to the vaccine

Zostavax
This is one of the shingles vaccines
Ingredients:
Active ingredients:
Live, attenuated varicella-zoster virus​
Inactive ingredients:
Amounts are based on a 0.65 mL dose
Salts: help maintain the stability and pH of the vaccine
Carbohydrates (sugars): normally used as stabilizers in vaccines
Other:
Some religions such as Islam and Judaism prohibit the consumption of porcine (pork) products. However, according to Jewish law, this does not extend to vaccines because it is not oral consumption. In addition, in Islam, the use of porcine gelatin in vaccines is permitted if lives are at risk and there are no alternatives.

Relevant Terms
-
Adenoviruses: a common family of viruses. These viruses can cause cold-like symptoms, conjunctivitis (pink eye), sore throat, and other symptoms. The version used in adenovirus vector vaccines is not able to cause these symptoms and cannot replicate.
-
Adenovirus vector: a version of an adenovirus that cannot replicate or cause disease. In this vaccine, it is used to deliver genetic information so that the body can make the spike protein.
-
Adjuvant: a compound added to some vaccines to strengthen the immune response
-
Antibody: a protein made by the immune system in response to a foreign particle (antigen). These proteins circulate in the blood and help defend the body against the substance.
-
Anticoagulant: a medicine that prevents blood from clotting too easily. Clotting is very important because it prevents people from bleeding too much if they get injured, but if blood clots too easily, it can harden and get stuck in the body. If a blood clot gets stuck, it can cause heart attacks, strokes, and other dangerous conditions.
-
Antigen: This is any substance that triggers the immune system to create antibodies. For example, allergens such as pollen are antigens.
-
Attenuated: The pathogen is weakened but not completely inactivated. Attenuated pathogens are too weak to cause disease in almost all people.
-
Carbohydrates: Another word for sugars
-
Conjugate: Attaching an antigen to a protein in order to improve the protection the vaccine provides.
-
Emulsifier: a substance that helps to keep the ingredients mixed together
-
pH: a measure of how acidic or basic a solution is. The scale ranges from 0 (very acidic) to 14 (very basic). A pH of 7 is neutral.
-
Serotype: a group of strains within a species that share a particular type of surface structure.
-
Spike protein: the protein in SARS-CoV-2 that allows the virus to recognize and attach to host cells.
-
Viral vector: a version of a virus that has been modified to contain genetic information from another source (in this case, the genetic information to make the spike protein). ​
