Generally, it is more appropriate to get vaccinated after two weeks of recovery from fever. Most fevers are caused by infections, which may be viral or bacterial, and it takes 1-2 weeks for the infection to return to normal after the fever disappears. Vaccines are often inactivated or attenuated viruses or bacteria, which can easily lead to infections when they are in the human body, so if the body does not fully recover during the fever and the resistance is weak, re-infection can easily occur. Therefore, it is better to wait for two weeks after recovery from fever before vaccination. During this period, it is necessary to drink more water and rest to strengthen the body’s immunity, which is also beneficial for the vaccination.
