Experts who pay attention to the health of the elderly: vaccination as soon as possible. Most people with chronic diseases can get safety and immune protection.

zoster virus
for example
after childhood infection
if the virus is not completely cleared
it will lurk in the ganglion for a long time
but as you get older or the disease affects the immune surveillance function
the latent virus may be activated. This can lead to herpes zoster disease
and some patients may even develop post
herpetic neuralgia
which lasts longer.It is understood that in an era when there is no vaccine
human beings can only get immune protection through natural infection
which is dangerous and uncontrollable. Guo Xiang said bluntly that vaccines are a powerful weapon for human beings to deal with diseases
and the reduction of disease incidence and health hazards caused by extensive vaccination is regarded as one of the greatest public health achievements of mankind. "by mimicking the similar mechanism by which pathogens enter the body
the vaccine promotes the immune response of cells to specific pathogens and produces protective antibodies in the body as early as possible
thus effectively dealing with the next possible pathogen infection." According to this expert
the vaccine promotes the body to have the ability to resist disease in advance
so vaccination has become an effective strategy to protect vulnerable people
The classic vaccine types are: live attenuated vaccine and inactivated vaccine. Guo Xiang said that live attenuated vaccines have a long history. Through attenuated pathogens
vaccines composed of intact viruses with reduced pathogenicity and good immunogenicity are obtained. However
live attenuated vaccines have some limitations
