Non-live vaccines, including inactivated, subunit, toxoid, and mRNA types, use killed pathogens or pieces of them to create immunity without causing disease. Common examples include the Flu shot (inactivated/recombinant), Tdap, Polio (IPV), Hepatitis A/B, HPV, and COVID-19 mRNA vaccines.

Which vaccines are not live vaccines?

The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples. Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria. The whooping cough (pertussis) vaccine is an example.

Which is not a live vaccine?

Messenger RNA vaccines—also called mRNA vaccines

mRNA vaccines have several benefits compared to other types of vaccines, including shorter manufacturing times and, because they do not contain a live virus, no risk of causing disease in the person getting vaccinated.

What are live and non-live vaccines?

Because they contain living bacteria or viruses, live-attenuated vaccines can provide enduring protection with only two doses. By contrast, non-live vaccines typically require at least three doses to achieve protection that fades over time and must be restored with booster doses.

Is the COVID vaccine live?

Vaccines do not use any live virus. Vaccines cannot cause infection with the virus that causes COVID-19 or other viruses.

Inside one local parent's choice to not vaccinate her children as measles cases increase nationwide.

Who should avoid live vaccines?

Severely immunocompromised persons generally should not receive live vaccines3. Because of the theoretical risk to the fetus, women known to be pregnant generally should not receive live, attenuated virus vaccines4.

Why refuse the Tdap vaccine?

Reasons to avoid the Tdap vaccine primarily involve severe allergic reactions to previous doses or vaccine components, certain neurological conditions like Guillain-Barré Syndrome (GBS) after a prior shot, or a history of encephalopathy (coma, prolonged seizures) following a previous pertussis vaccine, with moderate to severe illness on the day of vaccination being a reason to delay, not avoid. Personal beliefs, safety concerns (though risks of the disease far outweigh vaccine risks), or confusion about past vaccine reactions can also influence hesitancy, but medical contraindications are specific and usually involve severe reactions to past shots.

Is the polio vaccine live or non live?

IPV stands for “inactivated polio vaccine” and refers to the vaccine given as an injection. This is now the preferred vaccination for polio in the UK. As a child or in some countries outside of the UK, you might have received the oral polio vaccine (OPV); this is a “live” vaccine given as drops in the mouth.

What are the five live vaccines?

Examples of Live Viral Vaccines

• Chickenpox (varicella) vaccines.
• FluMist (intranasal flu nasal spray)
• Measles, mumps, and rubella (MMR) vaccines.
• Japanese encephalitis vaccine.
• Oral polio vaccine (no longer used in the United States)
• Rotavirus vaccines.

Is there a flu vaccine that is not live?

The inactivated influenza vaccine is made of killed influenza viruses or parts of the viruses. It protects against infection from influenza viruses and is given by injection. The vaccine does not protect against other viruses that cause colds or gastroenteritis (vomiting and diarrhea).

What vaccines are no longer recommended for children?

Recent major changes (early 2026) to U.S. federal vaccine guidelines removed universal recommendations for rotavirus, COVID-19, influenza, hepatitis A, hepatitis B, and meningococcal vaccines, shifting them to "shared clinical decision-making" (SCDM) or specific high-risk criteria, meaning parents must consult providers, while also reducing HPV doses. Vaccines for measles, polio, chickenpox, etc., remain routine, but families now need provider discussions for the shifted vaccines to determine individual necessity.

Is there a COVID vaccine that is not an mRNA vaccine?

Two types of COVID-19 vaccines are recommended for use in the United States: mRNA vaccines (Moderna and Pfizer-BioNTech) and a protein subunit vaccine (Novavax).

Are there any vaccines that are not safe?

The science that has been done has shown that vaccines are very safe. They're not perfectly safe; they do sometimes, very rarely cause adverse reactions.

What is an example of a live vaccine?

Examples of live virus vaccines are the chickenpox vaccine and the measles, mumps, and rubella (MMR) vaccine.

Is tetanus a live vaccine?

The Tdap vaccine does not have a live component because it is manufactured using inactivated noninfectious bacterial products that generate a robust immune response.

What are the six killer diseases of a child?

The six major childhood killer diseases are tuberculosis, diphtheria, pertussis (whooping cough), tetanus, poliomyelitis, and measles. These vaccine-preventable diseases can cause a lot of sickness and death in children if not stopped or treated quickly.

Who cannot get Tdap?

Tdap contraindications primarily include a severe allergic reaction (anaphylaxis) to a previous dose or vaccine component, and encephalopathy (coma, prolonged seizures) within seven days of a prior pertussis vaccine not caused by another condition, requiring deferral or use of Td instead. Progressive neurological conditions, or a history of Guillain-Barré syndrome after a tetanus vaccine, are also important precautions or contraindications, necessitating medical consultation. 

Which vaccines have the worst side effects?

MMR vaccine side effects (measles, mumps, and rubella)

These can include seizures (often associated with fever) or temporary low platelet count that can cause unusual bleeding or bruising. In people with serious immune system problems, this vaccine may cause an infection that may be life-threatening.

Why are doctors pushing the Tdap vaccine?

Whooping cough is a serious disease that can be deadly for young babies. Pregnant women can give their babies protection against whooping cough (pertussis) before their little ones are even born. Getting a whooping cough vaccine called Tdap during pregnancy helps protect mother and baby.

What vaccines do we not need?

For example, the United States does not recommend routine immunization for tuberculosis, typhoid, yellow fever, malaria, meningococcal disease (for infants), or dengue, while these are routinely recommended in other countries.

Who cannot take the live vaccine?

Immunosuppressive therapy (including biologics)

Individuals who are on or have recently received high doses of certain immunosuppressive or biological therapies (see list below) should not be given live vaccines because of the risk of severe or fatal infections.

What vaccines cannot be given together?

Note that there are two situations where vaccines cannot be given together: People who have anatomic asplenia (who do not have a spleen) or functional asplenia (whose spleen is not functioning properly) or have HIV should not get the meningococcal vaccine (MCV4) and pneumococcal conjugate vaccine (PCV13) together.
