Immunization Requirements 

All students must meet the immunization standards determined by the university. Under the direction of the California State University Chancellor, immunization for measles (rubeola) and German measles (rubella) is required for all students born after Jan. 1, 1957, while immunization for Hepatitis B is required for all first-time freshmen 18 years old or younger. The Hepatitis B vaccine is given in a series of three shots and takes six months to complete.

Students enrolled in a California public middle school or high school after July 1, 1999, will have already satisfied this requirement. If you were not enrolled in a California public middle school or high school after July 1, 1999, then you must provide verification of prior immunization or obtain immunization by the end of your first semester. If you’re immune because you’ve already had the disease, you may provide proof or have a blood test done. Verification or immunization for Hepatitis B must be completed before the end of your second semester.

Students will be unable to register for classes until each requirement is met. Log in to your myNorthridge Portal to check the status of a hold.

Proof of Immunization or Immunity

To fulfill the requirement, a student must bring written proof of immunization for measles, rubella and hepatitis B from a doctor or clinic to the Klotz Student Health Center. A school transcript will also be acceptable. If written proof is not available, students can receive the immunization at the health center. Students who cannot take the vaccination for religious, personal or medical reasons must sign a waiver.

Follow the instructions below to provide proof of your immunizations and to ensure you don’t have any holds on class registration. For more information or questions, call (818) 677-3666 and select the prompt for immunization information.

If you cannot provide proof in one of these forms, you may either get the immunizations or get a blood test to see if you have antibodies to measles, rubella and hepatitis B. Both services are available at the Klotz Student Health Center by appointment.

Measles (rubeola) and German measles (rubella)

For measles and German measles, proof can be provided in the following forms.

  • Documentation signed by a physician or nurse stating either that you received the two vaccines or stating you've had the diseases in the past
  • Laboratory evidence showing immunity to both measles and rubella
  • High school transcript confirming vaccination

Hepatitis B

By mandate of the California State University Chancellor, all students 18 years old or younger at time of first enrollment must provide proof of immunity to Hepatitis B. If you do not complete this requirement by the end of your second semester, you will not be able to register for classes.

Proof can be provided in the following forms.

  • Documentation signed by a physician or nurse stating that you either received the series of three vaccines (must indicate dates of all three immunizations) or you've had the disease in the past
  • Laboratory evidence showing immunity to Hepatitis B
  • Certified high school transcript confirming vaccination 

The requirement for rubeola, rubella, and hepatitis B immunization will be fulfilled only when you complete one of the following.

  • Bring proof of immunization to the Klotz Student Health Center
  • Fax documentation along with your student ID number, current address and phone number to (818) 677-2304, Attn: Health Information Management
  • Sign a waiver stating that you cannot get the immunization for religious, personal or medical reasons
  • Send a scanned document to

Colds and Flu

Colds and influenza, or the flu, are both caused by viruses, but not the same ones. Rhino (nose) viruses usually cause colds while influenza viruses cause the flu. The viruses spread from one person to another in respiratory droplets, often from coughing and sneezing. Crowded environments like classrooms and living areas can increase your risk of catching a cold or the flu.

The symptoms of colds and flu may be similar. However, cold symptoms are usually milder. This chart will help you distinguish whether you may have the cold or the flu.

Symptoms of cold and flu

FeverLess common, milderCommon
Muscle achesMild, infrequentVery common
FatigueMild, briefCan be severe
Nausea, vomiting and diarrheaUncommonMore likely with flu
Congestion, runny nose and sore throatMore common with coldsSore throat and/or chest congestion are more common than runny nose

Check with your health care provider if you have questions about your symptoms, if your symptoms are getting worse or persist without getting better. See your health care provider if your symptoms are severe or persistent or if you have dehydration, difficulty breathing or chronic health conditions such as diabetes, heart disease or lung disease.

Antibiotics do not work with viruses and there are no antiviral medicines that can cure a cold. To help prevent colds, avoid close contact with people who are contagious and wash your hands frequently. Avoid sharing eating utensils, bottles and cups. Cover your nose and mouth with a tissue when you sneeze or cough and dispose of the tissue in a trash can. 

If you are exposed to someone with influenza, antiviral medicines may possibly prevent the onset or, if given within the first 48 hours of illness, reduce the symptoms of flu. Please see your health care provider for advice. If you do get sick, the Klotz Student Health Center pharmacy has many medications that can help you alleviate your symptoms including fever fighters and decongestants, which are available without a prescription at low cost.

Flu Shots

One of the most useful ways to protect yourself from contracting influenza is to get a flu vaccine each year. Flu shots are available seasonally — usually in early to mid-October — for students, faculty and staff. Information on current vaccine supply and prioritization recommendations is available from the Centers for Disease Control (CDC). The Klotz Student Health Center supports the CDC's recommendations. 

Meningococcal Disease

Because college students, especially freshmen living in student housing, are at increased risk for meningococcal disease, the Advisory Committee of Immunization Practices of the Centers for Disease Control (CDC) recommends that colleges raise awareness about the disease and the benefits of immunization. In an effort to better serve you, the Klotz Student Health Center would like to provide you with the following information about meningococcal disease and its prevention with the meningitis vaccine.

Meningococcal disease is caused by the bacterium N. meningitides and is a leading cause of meningitis and blood-borne infection among teens and young adults. Approximately one in five victims dies despite antibiotic treatment, often within the first 24 hours of the onset of symptoms. The disease is airborne and breathed through respiratory secretions as well as by direct contact with a carrier by kissing and sharing drinking glasses.

College students are at higher risk of contracting meningitis. Studies have shown that crowded living conditions, a geographically diverse student population, radiator heat, active and passive smoking, bar patronage and alcohol consumption increase the risk of getting meningococcal disease. The incidence of invasive meningococcal infection is three times greater for students living on campus than those living off campus. Students living in dormitories were at least nine times more likely to get meningococcal disease than those not living in dorms.

More than 3,000 cases occur each year in the United States and are caused by various subgroups of the bacterium N. meningitides such as C, Y, B, A and W-135. Entering college students, particularly those living in residence halls and group housing, are advised to strongly consider getting a dose of the meningococcal vaccine. The vaccine, which is usually effective for three to five years, protects against the A, C, Y and W-135 strains of bacterium N. meningitides.

The vaccine is available at the Klotz Student Health Center. For more information, visit the American College Health Association's website.


Mumps is a viral infection that is considered relatively rare in the United States due to high vaccination rates that prevent the disease. However, there have recently been several outbreaks of mumps, primarily located in the Midwestern states. To date, there have been no reported outbreaks of mumps at California State University, Northridge or in the immediate area.

CSUN does not specifically require vaccination for mumps. As part of the university's admission requirements, CSUN students must provide proof of having received measles, mumps, and rubella vaccine (MMR); provide proof of immunity to measles and rubella; or receive a medical or religious waiver. Most people who have been vaccinated for measles and rubella have received the MMR vaccine, which also vaccinates for mumps.

The Klotz Student Health Center recommends that students, staff and faculty who are unsure of their immunization status review their immunization records with their health care provider.
