Hepatitis A and B

H‚Äč‚Äčepatitis A

Hepatitis A is a highly contagious disease, with the predominant mode of transmission being poor hygiene practices (not washing hands after using the toilet and then preparing food or drink for others - this is known as the fecal-oral route). The Hepatitis A vaccine is indicated for persons greater than 2 years of age.

The following individuals are at increased risk for infection with Hepatitis A:

  • Travelers to Third World or under-developed countries
  • Military personnel
  • Anyone living in areas of high endemicity
  • Certain ethnic groups
  • Persons engaging in high-risk sexual activity
  • Residents of a community experiencing an outbreak
  • Persons exposed to sewage (i.e., surfers)

There has been an outbreak of Hepatitis A in San Diego.  Read more at the County website: http://bit.ly/2x6d2Ct

  • Remember to wash your hands thoroughly before eating, and after using the restroom.
  • Don't share food, drinks, or smokes with others.
  • Use your own towels, toothbrushes and eating utensils.

It is recommended that all UCSD students should be vaccinated against Hepatitis A


The vaccine is contraindicated if there is a known allergy to any vaccine component (the vaccine is made in human cells, not blood plasma; and contains no egg antigens). There is no risk of HIV transmission or of any other disease with this vaccine. The vaccine, HAVRIX, is administered on day 0 and again 6 months later.

The vaccine is effective in 30 days. The duration of vaccine effectiveness is now believed to be lifelong. The vaccine does NOT protect against any other Hepatitis virus or other pathogens known to infect the liver.

Possible side effects might include: pain and redness at the injection site, headache, fatigue, loss of appetite, or nausea.

Hepatitis B

Hepatitis B is a highly contagious, potentially deadly virus. Anyone can get Hepatitis B, as it can be spread in many different ways. It is most often contracted through sex. It can be passed from mother to unborn baby in countries where the virus is endemic.

You MAY be at risk if....

  • You are a health care professional
  • You are a first-line responder who gives first aid or medical assistance (police, firefighter, EMT)
  • You ever come in contact with blood or body fluids at work
  • You or your parents have immigrated from a country where the virus is endemic (Asia, Africa)

You ARE at risk if.....

  • You have had more than one sexual partner in the last six months
  • You have had unprotected sex (without a condom)
  • You or your partner have ever been diagnosed with a sexually transmitted disease (herpes, gonorrhea, syphilis, chlamydia, genital warts, AIDS)
  • Someone in your household is a carrier of the Hepatitis B virus
  • You or your partner have had sexual contact with someone who has Hepatitis B or is at risk

Protect Yourself

The best way to protect yourself against this potentially fatal disease is to be vaccinated. Ideally the vaccine is given in a series of three shots over a period of six months (day 0, 1-2 months, and 4-6 months). 80% of protection is obtained after the first two doses and 98% protection after three doses are administered.

Possible side effects of the vaccine might include: pain and redness at the injection site, fever, headache, or dizziness.

If you need to complete the Hep A or B vaccine series, or need other immunizations, visit the Student Health Nurse's Clinic.
