A new clinical trial was published in the journal Pediatrics.Researchers have found that the quadrivalent live attenuated influenza vaccine (LAIV4), is also called the nasal spray vaccine. Just as safe for asthma children as the intramuscular inactivated influenza vaccine (IIV4), also known as the flu shot. The researchers found that the vaccine spray did not make breathing problems worse in a study of 151 children ages 5 to 17 with persistent asthma.Within 42 days of vaccination, 10.8% of children who received. The nasal spray vaccine experienced worsening asthma symptoms, compared with 14.7% of children who received the vaccine.
The nasal spray was developed as a painless alternative to the injection for patients aged 2 to 49 years.
