The nasal spray flu vaccine is approved for use in healthy non-pregnant individuals, 2 years through 49 years old. People with certain medical conditions should not receive the nasal spray flu vaccine.
The nasal spray flu vaccine contains small amounts of weakened flu viruses. They do not cause flu in children. As the main flu viruses can change each year, a new nasal spray vaccine has to be given each year. The brand of nasal spray flu vaccine available in the UK is called Fluenz Tetra.
Severely immunocompromised persons generally should not receive live vaccines (3). Because of the theoretical risk to the fetus, women known to be pregnant generally should not receive live, attenuated virus vaccines (4).
The nasal spray flu vaccine can only be used in healthy, younger adults who are not pregnant. In addition to the previously listed adults who should not receive the flu shot, adults should NOT get the nasal spray influenza vaccine if they: Are pregnant. Are ages 50 or older.
There are 2 vaccines that protect against chickenpox: The chickenpox vaccine protects children and adults from chickenpox. The MMRV vaccine protects children from measles, mumps, rubella, and chickenpox.
Invalid Contraindications to Vaccination
- Mild Illness.
- Moderate or Severe Acute Illness.
- Nonanaphylactic Allergy.
- Allergy to Products Not Present in Vaccines.
- Antimicrobial Therapy.
- Breastfeeding.
- Household Contacts of Pregnant or Immunosuppressed Persons.
- Preterm Birth.
Anything (including a symptom or medical condition) that is a reason for a person to not receive a particular treatment or procedure because it may be harmful. For example, having a bleeding disorder is a contraindication for taking aspirin because treatment with aspirin may cause excess bleeding.
People who are very immunocompromised can't have certain vaccines, such as the vaccine against measles, mumps and rubella, because the vaccine contains weakened live viruses that are too dangerous for damaged immune systems.
WHY IS LAIV NOT APPROVED FOR USE IN CHILDREN < 24 MONTHS OF AGE? LAIV (FLUMIST®) is contraindicated in this age group due to increased risk of wheezing.
The live attenuated influenza vaccine (LAIV) contains live forms of flu virus which have been weakened (attenuated). These stimulate the immune system but do not cause disease in healthy people. It can safely be given at the same time as all other routine childhood vaccines, including other live vaccines.
Flu vaccination can keep you from getting sick with flu.For example, during 2019-2020, flu vaccination prevented an estimated 7.5 million influenza illnesses, 3.7 million influenza-associated medical visits, 105,000 influenza-associated hospitalizations, and 6,300 influenza-associated deaths.
The best way to prevent influenza is to get a flu vaccine every year. The influenza virus is constantly changing. Each year, scientists work together to identify the virus strains that they believe will cause the most illness, and a new vaccine is made based on their recommendations.
For the nasal spray flu vaccine (i.e., the live attenuated influenza vaccine – LAIV), the starting CVVs are live, but weakened viruses that go through a different production process. FDA tests and approves all influenza vaccines prior to release and shipment.
