The “fourth injection” has been given in many places: each vaccination point is different, should the “Yangkang” population be given it?

Once the “fourth injection” of the new crown for special groups was opened, it was quickly rolled out in many places across the country. For the “Yangkang” group, after the infection recovers, the time interval for re-boosting immunization is also recommended to be more than 6 months. A new coronavirus research expert said that after experiencing an infection, even 6 months after the latest antibody production, the “memory” in immune B cells will persist, which means that existing antibodies are important for preventing severe illness and death still works. On the contrary, if the booster immunization is carried out again in a short period of time after the production of natural antibodies, it is equivalent to another shock to the human immune system, which is unnecessary and unsafe. | Related reading (First Finance and Economics)

Compared with other countries and regions, the biggest problem with the new crown vaccine in my country is that the elderly who should be vaccinated more have the lowest vaccination rate. And in this wave of infection, perhaps because everyone knows the power of Omicron, more people have been vaccinated with the fourth shot. However, rushing to get vaccinated at this time is a bit late. You may be infected before you can form antibodies after the vaccination. Second, you have to go out and get together to get vaccinated. For now, with proper protection, vaccination is still the best way to prevent and treat severe diseases for the elderly and people with underlying diseases.
