First, vaccines are not a privilege for children.
Perhaps in the impression of many adults, only children need to be vaccinated. In fact, this understanding is wrong. Adults also need vaccination, but children need vaccination more than adults. In addition to COVID-19 vaccine for adults, phv vaccine is also recommended for women between the ages of 26. During the outbreak of influenza, people over 6 months should be vaccinated with influenza vaccine, and adults should also be vaccinated with hepatitis B. To sum up, vaccination is not only the privilege of children, but also the routine vaccination of adults.
Second, you can't be safe after vaccination.
Many people may be narrow-minded and think that as long as they are vaccinated, they will not be infected. That was not the case. Because everyone's physical condition is different, some groups of antibodies will be destroyed after vaccination, and eventually they will be infected with the virus again. Vaccination is only to deepen our protection, not to get along after vaccination. After vaccination, preventive measures should be taken. In addition, vaccines are not life-long protection, and vaccines also have a shelf life. After the shelf life, you need to re-inject the vaccine to protect your body.
Third, the vaccine is not just a shot.
I used to think that the vaccine only needed one injection. Later, I learned that the number of injections actually depends on the type of vaccine. Some vaccines really only need one shot, but some vaccines need to be injected at intervals. For example, there are three kinds of vaccines in COVID-19, some need three shots, and some only need one shot. There are clear regulations on the interval of vaccination cycle.
Vaccine is a medical preventive measure. Vaccination can effectively prevent the spread of diseases, so we should all be vaccinated.
