September 25th, the autumn air is clear and cool.
My lover and I took Tao Bao Tao Niu to get the influenza vaccine with nasal spray. Tao Bao looked relaxed, Tao Niu pretended to be scared. In fact, she knew it was a squirting, either an injection or a deliberately teasing the nurse. After the injection, she said mischievously: It didn't feel anything, it was just a pack of anger when she got in.
Tao Bao is 17 years old. This is his 12th time to receive the influenza vaccine, the second time to receive the nasal spray influenza vaccine, and the last time, because the nasal spray vaccine is currently approved for the nasal spray vaccine, and it will be replaced in the future. Tao Niu received the ninth time influenza vaccine and the second time in the nasal spray flu vaccine. She is only in the second grade of elementary school and can still spray it for many years.

I chose nasal spray influenza vaccine for the two children, and there are many considerations. One of the very important points is that nasal spray vaccine acts on the respiratory tract and can produce mucosal immunity. It is possible to remove the virus when the influenza virus falls on the surface of the respiratory tract to achieve better prevention.
In the historical process of fighting the new crown epidemic, this mucosal immunity vaccine may be the strongest counterattack for humans.
htmlOn September 4, my country's inhaled new crown vaccine was approved for emergency use; two days later, another inhaled new crown vaccine in India was also approved for emergency use. Both vaccines are highlighted by mucosal immunity and have attracted much attention from the industry. The website of the authoritative international journal Nature published two articles in a row introducing the impact of mucosal immunity vaccine on the epidemic and was cautiously optimistic. htmlOn September 6, Nature published a news feature article with a clear optimistic title: How spray vaccines change the pandemic, while sub-titles are cautiously optimistic: Vaccine inhaled through the mouth and nose may prevent the spread of the coronavirus, although there is little evidence for human trials so far.

September 7 Nature released information again, introducing that China and India released the new crown vaccine , which acts on the respiratory mucosa, and used [Will it change the rules of the game] to imply that its technology is different from the current vaccine and may have a positive impact on the fight against the epidemic.

I have received 3 doses of the new crown vaccine. If the country arranges a 4th dose, I will first choose an inhaled vaccine that can produce mucosal immunity.
Mucosal immune vaccine is not a new technology. The earliest mucosal immune vaccine was the live oral polio vaccine launched in 1963. China is still using live oral polio vaccines for free vaccination in infants and young children. Oral vaccines for round diseases, oral vaccines for cholera, influenza nasal spray vaccines, etc. are also the mainstream mucosal immunization vaccines currently.
oral live polio vaccine is very effective. In addition to allowing individuals to prevent polio, compared with inactivated vaccine , its mucosal immunity can also greatly reduce the risk of virus excretion from the intestine to the outside world. It is also of great significance to block the spread and achieve herd immunity . Because of this advantage of live oral polio vaccine, scientists also hope that the new crown vaccine with mucosal immunity can stop the epidemic.
I have written about the advantages of nasal spray flu vaccine before (see for details: The flu vaccine is currently being vaccinated, and if you don’t want to get an injection, you can spray your nose, and the effect is surprising). I won’t talk about it anymore here. In fact, the nasal spray flu vaccine was given to my two children is the best proof of my recognition of this vaccine.
