What diseases do vaccines prevent?


It is important to vaccinate infants early and complete the full vaccination schedule from infancy to adulthood because it reduces the spread of vaccine preventable diseases and outbreak breaks. Thus protecting you and others (4).

On the CDC schedule there are 17 on the standard vaccination schedule from birth to 18 years old (3):
  • Diphtheria, Haemophilus influenza type b (Hib disease, is a major cause of bacterial meningitis), Hepatitis A, Hepatitis B, Human Papillomavirus (HPV is a major cause for cervical and other cancers), Influenza (Flu), Measles, Meningococcal, Mumps, Pertussis (Whooping Cough), Pneumococcal (causes bacterial meningitis and blood infections), Polio, Rotavirus, Rubella (German Measles), Tetanus (Lockjaw), and Varicella (Chickenpox) (3).
  • Meningococcal B is on the CDC schedule however, this vaccine will3 depend on the clinic or doctor’s office you go to and if they carry it (3).  In addition to the 17 previously mentioned on the adult schedule there is an additional vaccine for Shingles (Herpes Zooster) for which there is an option for a live attenuated or recombinant vaccine (1)

There are other vaccines available for:

Cholera – there is a vaccine for cholera in the US that has been approved by the FDA called Vaxchora (lyophilized CVD 103-HgR). It is a live attenuated vaccine and a single vaccine for adults 18 -64 years’ old who are traveling to an area that has active cholera transmission or is endemic. Endemic means that a place has regularly reported outbreaks (7).

Rabies – There is a vaccine for rabies, however, it is recommended for high risk groups such as veterinaries, animal handlers, and certain laboratory workers. However, being vaccinated does not mean that one should not seek immediate medical attention after being exposed to rabies (9).

Anthrax – there is a vaccine available to prevent anthrax, however, this is not typically available to the general public and really only available for people who are at increased risk of coming into contact with or have already came into contact with it (2).  

Typhoid – There is a vaccine for Typhoid fever that may help to prevent it, however the CDC only recommends this vaccine to people who are travelling to places where typhoid fever is common, such as South Asia, India, Pakistan, or Bangladesh. There are two types available in the US. The oral vaccine is a live attenuated vaccine able to given to people at least 6 years of age and consist of four pills that need to be taken every other day and should be finished at least 1 week before travel. There is an injectable vaccine that is an inactivated type and is able to be given to people at least to people at least 2 years of age and should be given at least 2 weeks before travel. However, keep in that the vaccine is not 100% effective and the CDC recommends to practice safe eating and drinking habits to help prevent infection. Either way if someone does get vaccinated the vaccine losses its effectiveness over and boosters are required every 2 years for the injectable and every 5 years for the oral vaccine (8). 

Tuberculosis – There is a vaccine called Bacille Calmette-GuĂ©rin (BCG) for tuberculosis (TB). However, in the united states it is not used in the US, but it is given to infants and children in other countries where TB is common. This vaccine does not always protect people from contracting TB and immunity wears off. However, the BCG vaccine is recommended for health care workers who may might chance of coming into with them. Since there is a high percentage of TB patients with TB strains that resistant drug resistant (10).


Yellow fever – There is a safe and effective yellow fever vaccine that has been available for more than 80 years and recommended for those ages 9 months or older and are traveling or living in areas with high risks for yellow in Africa and South America. Sometimes this vaccine may be required in order to enter certain countries. The vaccine itself is a live attenuated form of the virus and only is one shot (10).


Ebola – the FDA approved the first Ebola vaccine called Ervebo (rVSV-ZEBOV) on December 19, 2019. The vaccine is a single dose vaccine and has been found to be safe. The vaccine protects against only Zaire ebolavirus species of ebolavirus and not the others (4).
