You can’t get flu from the flu vaccine as it doesn’t contain the live virus, so those adults were wrong *@Aishah231*
The nasal spray is different but I think it has very weak live virus so very unlikely to cause flu.
Actually, the nasal flu vaccine
does contain live flu virus in it. The flu virus, while alive, is attenuated, which basically means weakened. This means the vaccine cannot cause flu in the recipient or others by viral shedding post vaccine but it can cause flu symptoms such as runny nose, blocked nose- which for some asthmatics can trigger their asthma.
Which is one reason why children with severe asthma get the flu shot instead of the nasal spray. The other reason is that the flu shot is actually more effective than the nasal spray in terms of immunity response and asthmatics need the best protection more than nonasthmatics from flu. (Nasal spray is cheaper)
All my DC got the annual flu vaccine, the two with severe asthma were given the flu shot not the nasal spray.
